Here's the deal: You may have done a complete cleaning, vacuuming, and wiping of your home or a thorough cleaning and bathing of your furry family member—it doesn’t matter: Every time your dog gets up and shakes itself, a huge amount of pet hair, dust, and dander are wafted in the air.

So even if you clean meticulously, if you own a pet, chances are there is plenty of hair, dander, and other small particles in the indoor air you breathe.

And not only is the hair and dander causing issues with cleanliness, but they can also make your nose itch and your eyes water.

What if you could get cleaner air and get rid of some of that pet hair, dander and odors at the same time? Having an effective air purifier guarantees clean and fresh air while saving you a ton of cleaning.

    Coway Airmega AP-1512HH(W) True HEPA Purifier with Air Quality Monitoring, Auto, Timer, Filter Indicator, and Eco Mode, White

    Coway first began devoting research and development processes to environmental solutions back in 1989. Their aim to enhance general living standards also mixes with their desire to produce and provide a visually appealing product with powerful performance to make your life easier.

    Size and Coverage

    Since the Coway Mighty air purifier is compact by design, it can comfortably fit into any home and room, but it’s also perfect for a big space—it can clean up rooms that are up 528 square feet (about the size of a 3-car garage) in one go.


    With its four-stage filtration system (Pre-Filter, Carbon(Odor) Filter, True HEPA Filter, and Ionizer) you will definitely get cleaner than clean air.

    The micro-mesh pre-filter will catch larger particles and lengthen the lifetime of the other filtering parts, and the carbon filter will take care of all those nasty smells.

    To effectively eliminate dander, pollutants and other small particles the Coway AP-1512HH Mighty Air Purifier then uses a HEPA-filter and finally an ionizer to catch anything that wasn't caught by the three previous filters. And if you don't want to use the ionizer to be environmentally friendly, you can always turn it off when it is not needed.

    The indicators alert the owner when it’s time to change the filter—so you don't have to worry about whether the filter is full or not. It comes with a replacement filter pack—one package that comes with two carbon pre-filters and a replacement HEPA filter, leaving you good to go for about a year.


    This Coway air purifier uses the Eco Mode to save energy when the Air Quality Indicator has not detected pollution for 30 minutes. On the other hand, the indicator uses particle sensor technology to monitor the air quality and kicks the fan to high gear when needed. It has 3-speed settings, auto mode, and eco mode.

    The Mighty Air Purifier also can be set on a timer, from one to four- to eight-hour increments, which can help you time it during the night.

    Noise level

    Although you don't have to worry about it being noisy either, with quiet operation, this purifier is a silent killer of air-borne pet hair.

    LEVOIT LV-PUR131 Air Purifier

    A popular and well-performing air purifier with excellent 3-stage filtration including a True HEPA filter and an activated carbon filter. Check the latest price.

    Key Features

    • Coverage up to 360 sq. ft.
    • 3-stage filtration
    • Air quality monitor
    • True HEPA filter
    • Activated carbon filter
    • Auto-mode and sleep mode
    • Easy-to-use LED display
    • Energy Star
    • 2-Year Warranty
    • CADR Rated 135+ CFM(233m³/h)

    This LEVOIT Air Purifier has been designed in California. It is 100% ozone free, and it does not use UV or ions to clean the air.

    Size and Coverage

    This is not the smallest of air purifiers, but it does cover up 360 square feet and will purify a large room of that size in just 10 minutes.

    If you need an air purifier that can cover a larger area, Levoit has a similar large room air purifier that can cover up to 3175 sq ft. Although the design is different, the features are similar and we can recommend it for pet homes as well. You can find this air purifier for larger areas here.


    The 3-stage filtration system consists of a pre-filter, True HEPA filter and an activated carbon filter. The pre-filter will capture larger particles like pet hair and protect the HEPA filter from being clogged.

    The HEPA filter captures 99.97% of particles as small as 0.3 microns, which means it will clear the air of allergens like pollen, mold spores, and pet dander. An air purifier with a HEPA filter is an excellent choice for pet homes because it will significantly reduce the amount of pet dander floating in the air causing your eyes to itch and your nose to run. Especially if you have family members that have a sensitivity towards some of the most common allergens, an air purifier with a HEPA filter should be your choice. In addition, we love the fact that this is a True HEPA filter meaning that the filtration system is sealed and won’t leak nasty particles back into the air before they have been removed by the filters.

    The third filter is an activated carbon filter which will eliminate the nasty smells you might notice in your home. Pet owners may find an odor eliminating filter especially useful since pets can produce all kinds of unpleasant smells from the cat pee smell to the musty odor wafted into the air by your wet dog.

    With this 3-stage filtration system, the air in your home will be fresh and clean.


    The automatic sensors and air quality indicator will inform you about the surrounding air quality so that you can adjust your machine accordingly.

    You can adjust the speed of the fan manually, but this Levoit air purifier also has a smart, automated mode which will automatically adjust the fan speed to purify your air faster when it detects impurities.

    You also have a sleep mode which is slower and quieter but will ensure you get a restful nights sleep with the air in your bedroom being clean and fresh. You can turn on the auto-off timer if you wish, although many users prefer to keep the air purifier quietly running through the night. After all, you do spend 7-9 hours in the bed every night, and clean air will help you sleep better.

    If you want to control the air purifier with your smartphone, there is also an updated version of this air purifier with a Wi-Fi connection. It will allow you to control the air purifier using the free VeSync application. You can even use scheduling and customize how your air purifier runs.

    Noise level

    This air purifier is very quiet with the noise being only 28dB on the lowest setting. This means that you can easily use it during the night to guarantee you fresh air and a good nights sleep. The humming sound of this machine is also pleasant, and users feel it does not disturb them during the day even with the automatic setting.



    + Good coverage
    + 100% Ozone free
    + Air quality sensors
    + Automatic mode and sleep mode
    + 3-stage filtration with True HEPA and activated carbon filters
    + Eliminates allergens, pollen, airborne bacteria and odors
    + Quiet at only 28 dB on the lowest setting
    + Wi-Fi connectivity available


    - Does not detect odors well
    - No remote

    Summed up

    This popular Levoit air purifier has gained excellent ratings form many satisfied users. It is not a highly advanced model, but if you are looking for something that is moderately priced and cleans the air efficiently, this air purifier is a great choice. It is easy to use, effective and it has an excellent filtration system that removes even the smallest particles and odors.

    If you’re looking for an air purifier for a pet home to help you deal with pet hair, allergens and pet-related odors amongst other things, then this air purifier is one of the top choices.

    Pure Enrichment PureZone 3-in-1 True HEPA Air Purifier

    A compact air purifier with modern design and efficient filtration. A fairly basic but very functional bestselling product. See the latest price here.

    Key Features

    • Coverage 200 sq ft
    • Compact and modern design
    • True HEPA filter
    • Activated carbon filter
    • UV-C light to eliminate viruses and bacteria
    • Three speed settings
    • Auto Off Timer for 2,4 and 8 hours
    • Noise level 30dB
    • 5-year limited warranty
    • CADR: 80 cfm

    This popular air purifier is manufactured by Pure Enrichment, who are dedicated to producing sleek premium products that enrich your everyday life. They aim at building carefully designed products that last for many years.

    Size and Coverage

    The Pure Enrichment PureZone 3-in-1 True HEPA Air Purifier can cover rooms up to 200 square feet in size. It is not suitable for more massive rooms or homes, but that makes sense as when it comes to size the product is pretty compact. It has a sleek and modern design, and with the whisper-quiet operation, it will blend right in.


    The PureZone 3-in-1 air purifier has a three-stage cleaning system with three filters: pre-filter, activated carbon filter, and a HEPA filter.

    A HEPA filter can filter out 99.97% of particles as small as 0.3 microns. That means it can remove dust, pollen, pet dander, smoke and mold spores among other nasty particles you wouldn’t want in your indoor air. Since the filter is a True HEPA filter, the system is sealed preventing unfiltered air from leaking out before it travels through the filtration system and gets cleaned.

    The second filter is an activated carbon filter which can filter out many household odors like the smell of cooking or pets. It is a great way to guarantee a nice smelling home even if you have a cat litter box or dogs that have that musty smell when their fur gets wet.

    The machine also uses UV-C light to safely destroy any viruses, bacteria or fungi in the air it filters. It is a great way to prevent germs from spreading through the air you breathe in your home.


    The PureZone air purifier has three speed settings you can control manually. The highest speed setting is great if you want to clean stuffy air quickly while the medium setting is the best choice for continuous purification.

    The lowest setting, on the other hand, is what you want to use if you’re going to use the air purifier during the night because it is the quietest while still keeping the air in your bedroom fresh. The automatic timer can be set to shut off the air purifier after 2, 4 or 8 hours for energy efficiency.

    Noise level

    The noise level of this PureZone air purifier is only 30dB at the lowest setting and 50dB on the highest. Even on the fastest fan speed, the sound the machine makes is a quiet humming, and with the lowest setting, you can comfortably sleep with the air purifier next to your bed.


    + True HEPA filter to reduce allergens
    + Activated carbon filter to eliminate smells
    + UV-C light to destroy bacteria and viruses
    + Tree speed settings
    + Quiet with a noise level of 30dB
    + Automatic timer for energy efficiency
    + Sleek design


    - Not suitable for large rooms
    - Does not have an air quality indicator

    Summed up

    This is a fairly basic but efficient air purifier for small to medium-sized rooms. It is an excellent option if you’re looking for something compact and moderately priced. The filtration system is capable, and it will guarantee you fresh and clean air free of dust, dander, pet hair and even germs.

    Why do you need an air purifier for pet hair?

    There are many ways to remove pet hair from the air - one of them is by using an air purifier. Although these air purifiers won’t completely 100 percent get rid of all pet hair in the air, it will do a pretty good job at it.

    After tackling the couch and thick carpet with the vacuum, you can rely on the air purifier to take care of all the dog hair wafted into the air by your cleaning efforts.

    dust and dander on table

    Without an air purifier, once the dust settles, it settles. And it settles as dander and hair back on the floor which you then need to mop or vacuum again.

    For starters, consider this fact for a moment:

    More than 50 million Americans experience various types of allergies each year, according to the Asthma and Allergy Foundation of America, with cat and dog dander being the most common triggers.

    That means that there are a lot of Americans suffering from pet allergies that can be eliminated or reduced with the proper care and maintenance.

    You might have already been using dehumidifiers to inhibit mold, mildew, and dust mites' growth if they are your main triggers of allergies.  Even though a traditional dehumidifier doesn’t directly target pet dander, your allergies will be less likely to act up if you manage to control your humidity level below  55% Relative Humidity (RH).

    What's even better, you can enjoy both ideal humidity and fewer allergens in the air by upgrading to a pet hair dehumidifier air purifier combo. Check out our article about the best dehumidifiers for homes with pets to find out more. They will make a huge difference in clearing the air—of dog hair and dander that is.

    How does an air purifier for dog or cat hair work?

    Many efficient air purifiers have enough power to circulate the indoor air and capture the pet hair floating around. You just have to pick one that suits the room size or the size of your house or apartment. When the air is circulating through the air purifier, it will also catch the dog and cat hair.

    But, it's not just about the hair when you have a pet in the house. Your dog can carry all kinds pollutants inside in its fur, and if you have seen a dog shake itself in direct sunlight, you know their coating is full of dust and other small particles which are wafted into the indoor air. Moreover, of course, there is the dander.

    To get the best chance of getting all that dog dander out of the air in your home, you should invest in a purifier with a HEPA-type or true-HEPA filter. These filters are responsible for trapping particles in its system that are down to 2-4 microns in size. Fortunately, dander is 2-3 microns.

    This filter will then capture and retain the animal dander, dust, and other pollutants, thus lowering the possibility of you or your family’s allergies acting up.

    To be fair, these air purifiers can only reach the hairs floating around in the air—not settled in your sofa or on your shirt. It would be pretty dangerous if it were powerful enough to suck up pet hair embedded in your couch - if it were that powerful, it might suck in your pet as well!

    You still need to vacuum; however, it can definitely help to leave less pet hair floating in the air than before, and reduce sneezing down to a minimum.

    Fortunately, most dog hair will stay in the air before it settles, so the air purifier will take care of that floating hair before it goes out of bounds and out of play—for the purifier, that is (you can still tackle it with a lint roller or a vacuum).

    Factors That Will Affect Your Choice

    It’s essential for you to realize a few things about pet hair and dander before you invest in an air purifier.

    • Pet hair is not the culprit behind your allergies acting up—it’s the pet dander that’s attached to the hair that causes you to sneeze, your eyes to water, and your nose to get stuffy.
    • If it’s just pet hair you're worried about any “HEPA-type” filter should work sufficiently enough to remove the pesky hair floating around. However, if you have allergies, you should invest in a “true” HEPA filter, which will eliminate the dander floating in the air and causing your allergies to act up.
    • You should aim for a pre-filter or a filter screen that is separate and can be removed and cleaned, which will lengthen the lifetime of the HEPA-filter.
    • If you're looking to eliminate pet odors as well as hair and dander, you should invest in an activated carbon filter which will reduce all kinds of foul smells your pet leaves behind. Also, you may want to check out our article focusing especially on air purifiers for odor elimination.

    Buying guide - how to choose the best air purifier for pet hair?

    Pets: A part of our family. Our best friends. A great source of joy and love and affection.

    But also—foul-smelling, gas-passing fur balls who shed hair and dander into the air of our homes.

    Although the cute outweighs the shedding and bad smells, having a pet can actually decrease the indoor air quality quite dramatically.

    kitten on floor

    If you have allergies or sensitivities, pet dander is likely to cause your allergies to act up, and even if you don’t have diagnosed allergies, you probably enjoy breathing clean, fresh and odorless air without dander, dust, pet hair and other nasty particles.

    It is therefore essential to invest in a good quality air purifier which has the ability to remove pet dander, hair, and odor in the air.

    You also might want to invest in a purifier to filter dust, smoke, fumes and any other particles that may cause air congestion in your home.

    11 Things to Consider Before Buying an Air Purifier for Pets

    1. The Size of the Room:

    The air purifier you purchase should have the capacity to cover your room or the home you live in. You will need to know the measurements—which doesn’t mean you have to get out your graphing calculator from seventh-grade math class. Simply estimate and multiply the length and width of the room to get the dimensions in square feet.

    2. Placement of the Air Purifier:

    You need to find a location in your home where you will install the air purifier—which will probably end up where you and your family (and also your pet) mostly spend your time.

    Many people install the air purifier in the bedroom because you spend somewhere around 6-10 hours asleep every night, and clean air will help you sleep better. If you do choose your bedroom as the optimal location, make sure silence is a key feature of the purifier so it won’t disturb you while you’re sleeping.

    Other common places to put your air purifier are the kitchen and living area. A kitchen is an excellent place for the air purifier if you want the purifier to filter our odors that come from cooking. However, if your primary goal for the air purifier is to filter out dust, then you might want to place it in the living area where most of the dust gets wafted into the air.

    Also, if you’re a cat owner, placing the air purifier somewhere near your cat’s litter box will eliminate the cat pee smell.

    3. Type of Filtration:

    If the main reason for the purifier is to reduce pet hair, odor, dander, dust, smoke, and pollen, find an air purifier with a HEPA filter. Filters that are HEPA standard must remove 99.97% of particles that have a size greater than or equal to 0.3 µm.If you have allergies or sensitivities, it is especially important to find an air purifier with a HEPA filter, because it will filter out those allergens that trigger your symptoms.

    However, if the main problem is viruses or bacteria, an air purifier with UV-C technology, ozone purifiers or ionizers will be ideal.

    4. Maintenance Cost:

    To help with your budget (and bank account) an air purifier which is easy to maintain, clean, and operate can save you in the long run.This will save you both your time and effort. Also, check the availability of spare parts and the cost for replacement; otherwise you might end up with a purifier expensive to fix and maintain. It might be a good idea to buy a few spare filters when buying the air purifier. That way you have an extra one at hand when you notice it is time to change the filter.

    5. Automatic Monitoring:

    This is a feature that allows the purifier to automatically adjust the speed of cleaning the air when there are any changes in its quality. This is a handy feature because it keeps up the air quality automatically. Without this function, you will need to adjust the air purifier yourself once you notice the air is stuffy and the air quality has already gone down.

    6. Power Consumption:

    Air purifiers for pets run 24/7 to make sure that the air you breathe is kept clean and fresh. However, this comes at the cost of your monthly electricity bill. You may need to consider buying an air purifier which has lower power consumption but still has the capacity to clean the air.

    7. The Level of Noise:

    If you can sleep through heavy rain, vacuum cleaning or any other noise, then chances are you probably won’t have a problem with a noisy purifier. However, if you can’t handle too much noise and still get a quiet night’s sleep, then consider getting yourself an air purifier that emphasizes more silent operation.

    8. Effectiveness:

    The purifier’s Air Change Rate or ACR is also an important feature. This is the number of times the purifier can clean the air within a given space in an hour.

    9. The Reputation of the Manufacturer:

    Known manufacturers protect their reputation by continuously producing quality products in order to satisfy their customers. By researching into a manufacturer’s quality, history, and past customer reviews, you can factor in the manufacturer's reputation.

    PetHairPatrol will only recommend products from well-known manufacturers that produce high-quality machines. By choosing one of the products we recommend, you can rest assured the research has been done for you.

    10. After-Sale Customer Service:

    The technical support that you may need after your pet air purifier has been installed is also a contributing factor to the overall quality of the product. Purifiers tend to wear and tear with continuous use. So, you can feel safer knowing that you will always have someone to help should any problem arise.

    Choosing a product from a well-known company is a good idea because they often have the best customer service. Again, PetHairPatrol will not recommend any products or manufacturers that are known for slacking with customer support.

    11. Warranty:

    In the long run, the air purifier might break down. Instead of throwing it away, you may want to know if the company covers parts or full product on the warranty. It could be lifetime free service or replacement of the entire product or damaged parts of the air purifier. Always check out any guarantee before purchasing the purifier.

    PetHairPatrol will recommend only products that we find have an adequate warranty. If you buy online on Amazon, you can easily find information about the warranty on the product page.

    Pet Dander vs. Pet Hair - Understanding the differences

    As a pet owner, it is important for you to understand the differences between pet dander and hair, and understand how both affect your health. This information will help you in deciding the best air purifier to meet your specific needs.

    Studies have shown that people who own pets are likely to experience pet allergy symptoms, including a runny nose, itchy watery eyes, sneezing, congestion, and having difficulty when breathing.

    Most people will think that these allergies are caused by breathing in their pet's hair, but that is not the case.

    Pet allergies are actually caused by the microscopic dander shed by the pets.

    Pet dander is the tiny flecks of the skin that peels off with the pet’s hair, feathers or fur during shedding. Pet dander not only comes from dogs and cats but also other pet animals for example guinea pigs, hamsters, ferrets, and birds, which cause allergies in humans.

    On the other hand, pet hair is simply the hair or fur of your pet, just as how the name suggests.

    Coming in contact with pet hair does not cause any allergic reactions in humans. The only problem with pet hair is that they make a mess on the furniture and collect on the floor or stick to your clothes.

    Important Features for Air Purifiers in Pet Homes

    If anyone in your household experiences allergic reactions from pets, including cats, dogs or birds, be sure to purchase the best air purifier for pet dander in the market.

    The best product will be one with a True HEPA filter.

    This is because this air purifier is the only one certified to remove allergens up to 99.97% which includes pet dander from any animal, not just cats, and dogs. You will not need to purchase a specific air purifier for cat allergies and dog allergies—this filter does all the work.

    By pulling the pet dander and enclosing them in the True HEPA filter, the purifier works best running 24/7 to rid the air of dander and keep it clean.

    A simple, HEPA-type filter is a bit cheaper than the True HEPA filter and only has one major difference—its capability of trapping particles between 2-4 microns. This means that this air filter for pet hair is capable of removing pet hair from the air making it one the best air purifiers for cat hair or dog hair (and a little more affordable than the True filter).

    If you want to get rid of pet odor in your home using an air purifier, the most important feature to look for in an air purifier is one that comes with an Activated Carbon filter. This is a type of filter designed to absorb the smell produced by pets in your home. You can find our listing of best air purifiers for odor elimination here.

    Other Types of Pet Air Purifiers

    Apart from the above air purifiers for pets that have air filters as their main features, here are some other models:

    • Ionizers: This type of air purifier electrically charges the air surrounding it so that all the particles within its range are negatively charged. The particles are then attracted to a collecting plate which is positively charged. Sometimes, the particles attach themselves to surfaces and walls. This type of air purifier is good at inactivating bacteria and viruses, but not effective in eliminating pet dander and odor.
    • UV purifiers: This type of air purifier uses UV-C light to kill allergens and germs and inactivate other particles in the air.
    • Ozone purifiers: These air purifiers are known to use the process of oxidation in damaging the membranes of bacteria and other organisms, inactivating them. Unfortunately, they are not effective in removing pet odor and dander.

    4 other Essential Features of a Good Pet Air Purifier

    These are the 4 other essential features that an air purifier for pets must have:

    1. Sensors for Air Quality: This is basically the brain of the air purifier. It monitors the air quality in your home continuously and consistently. If there are any changes in air quality, the sensors are responsible for adjusting the speed of the air cleaning properties of the purifier, in order to bring back the air quality back to the desired levels.
    2. Anti-bacterial Coating: Not all the air purifiers will have this feature. However, there are filtration systems that have an additional layer of coating with antibacterial properties. This means that the particles filtered will come in contact with the anti-bacterial coating, making them ineffective.
    3. Purifying capacity: You can know the purifying capacity of your purifier by checking the Clean Air Delivery Rate (CADR). The CADR shows the efficiency of the air purifier in eliminating contaminated air particles within a given period of time and space occupied. The higher the CADR, the better the purifier is in cleaning the air. However, before you buy, take into consideration the size of the room and the CADR ratings.
    4. Security features such as child-lock: Especially if you have young ones in your home, (and they are particularly curious) precautions taken with the purifier are highly important. You should be setting the program and then being sure that it won’t be altered in any way (due to a wandering child).

    Air Purifiers with Washable Filters

    Most air purifiers use filters that last for 3-6 months and need to be replaced since they are clogged with dirt, which discourages them from working properly.

    Fortunately, the best air purifiers with washable filters in the market will have minimum maintenance. These filters are reusable and you don't need to replace them since you can just wash them and put them back in the purifier.

    Air Purifiers for Removing Dust

    It is recommended to remove dust particles from the air in your home as they can cause allergies and asthma.

    Investing in an air purifier to remove dust is the best way to ensure that the air you and your loved ones breathe is cleaner, safer, and dust free.

    Benefits of Using an Air Purifier for Pets

    Reduced cleaning

    The positive side of having an air purifier in your home is that you won’t have to worry about that extra cleaning since it is run on a daily basis. Making the purifier run 24/7 helps remove dust, dander, and hair making your home cleaner.

    A fresher home environment

    Different pets produce different types of odors.

    Cats move around the house freely and mostly stay indoors.

    Dogs, on the other hand, bring odors from outdoors when you take them for a walk or when they use the potty and come back in the house.

    Indoor pets such as birds, ferrets, and potbelly pigs contribute to the smell through their cages and litter pans.

    Regular cleaning helps in controlling the smell, but sometimes the unpleasant smell is out of control.

    Having an air purifier will always ensure that your home is smelling fresher as it neutralizes the smell and does not cover it up like the scented candles and air freshener sprays.

    So, should you buy an air purifier?  In pet homes it can be beneficial because it can:

    • Filter out dander that triggers allergies
    • Remover pet hair and dust reducing the need to clean
    • Eliminate pet smells
    • Provide fresh, clean and healthy indoor air for you to breathe


    Investing in an air purifier is a big investment. Not only with the initial purchase but you have to realize that you'll probably end up having these purifiers for the next few years. We realize that with such a commitment, you might have a few questions. Here are our most FAQ to help you out:

    An air purifier is essential because it filters out the air particles that you don’t want to breathe in. The particles in the air maybe things like pet hair, dander, odor, dust, smoke or any other tiny particle that may cause harm to the body.

    If you or anyone in your family suffers from allergies or asthma, purchasing an air purifier could be the right thing to do to keep the air clean around them.

    Although it will not get all the dog hair out of your home, it will definitely help out—as long as you've invested in one with powerful air circulation and excellent filtration.

    Just think of all the hair, dust and dander being lifted to the air every time you vacuum or your dog shakes itself. The air purifier will circulate the indoor air filtering out all these particles before they settle as dust on your floor.

    Having an air purifier will not eliminate the need to vacuum completely, but it will definitely reduce the times you have to do a thorough clean-up with your vacuum.

    Even if you don't have allergies (and especially if you do), we suggest you pick out an air purifier that has a HEPA-filter. These filters have a promise of ousting 99.97% of contaminants larger than 0.3 of a micron. Having excellent filtration will make sure the air in your home is always clean and fresh.

    Especially if you have a long-haired dog, this might be your heaviest concern.

    When your dog sheds, the fur will get everywhere—from the floor to the sofa to the bed—even to your clothes! However, the air purifier will focus solely on that fur that’s floating around in the air before it settles. This is the target goal of these air purifiers.

    So, if your problem is dog or cat hair that’s stuck to your furniture, the air purifier cannot do anything about it—it’s best if you invest in a vacuum for that.

    However, for that hair that’s still floating around in the air and polluting your breathing environment, you can definitely benefit from an air purifier.

    Every time your dog gets up and shakes itself, a huge amount of dust, dander, hair and other small particles are wafted in the air. Unless you have an air purifier to do the task for you, you will have to take out the vacuum once the dust has settled.

    Having an air purifier guarantees clean and fresh air while saving you a ton of cleaning.

    This is where the majority of your allergies will come from—the dog dander.

    Scientifically speaking, the several proteins that are found within the dander is what may cause allergy symptoms. With an air purifier, the air around you becomes cleaner because it filters out skin cells, urine, saliva and even the proteins that cause allergy symptoms—if they are all in the air.

    Ultimately, the air purifier will focus on making the air around you as breathable as possible for you—giving you clean air and lessening the triggering of any allergy symptoms by inhaling that dander from your beloved dog.

    If you own a pet, chances are there is plenty of pet hair in the air of your home, especially during the shedding season.

    You may have done a thorough cleaning, vacuuming, and wiping of your home or a thorough cleaning and bathing of your furry family member—it doesn’t matter: there is still hair in the air.

    An excellent way to remove pet hair, dander, and dust from the air is by using a powerful air purifier. The purifier will trap in the nasty particles releasing fresh air to your home.

    Definitely. Air purifiers are as safe for pets as they are for you.

    Just like humans, pets need to breathe fresh air, free from odors and other microscopic organisms that may be harmful. And although they are the main ones causing the pet hair and dander in the air, that shouldn’t make them suffer from it.

    Pets also can be affected by the different types of chemicals present in your home. Therefore, an air purifier is essential for your furry friend to be a happy pet.

    However, not all air purifiers are suited for pets like birds. Ionizers use the process of oxidation to kill germs, bacteria, and viruses, which may cause harm to birds since they cannot handle too much oxygen in the air.

    Yes, air purifiers help with pet allergies.
