There are so many air purifiers out there to choose from. You may be asking that very question – which air purifier is best for pet dander?
I’ll cover some basic information you need to know about pet allergies and show you some of the best air purifiers for your money to relieve pet dander problems, along with some brief reviews to help you decide.
Infographic – Pet allergies and pet dander facts
What is pet dander?
Pet dander is actually made up of skin flakes shed by pets. These, in turn, cause an allergic reaction in humans. It’s carried by the fur of pets and is also distributed by the air around you.
Pet dander, just like human skin cells we all shed, is what causes dust mites to thrive. This is another major source of allergies you’ll have to worry about! So, in fact, reducing pet dander helps you in more ways than you may have realized.
Another fact: Although cats are found in fewer homes than dogs they account for more allergies when compared to dogs.
Also, male cats produce less allergen material than female cats. Interestingly, enough, older animals have been shown to actually produce more dander skin shedding than younger pets.
Facts & myths about pet allergies
Note: While it’s true that no animals are completely hypoallergenic (meaning they don’t cause allergies) the amount of hair they produce can vary. For example, there are a number of dog breeds that don’t shed much or at all and can reduce the amount of pet hair in your home.
Why pet dander is hard to deal with
A microscopic image of pet dander and organic proteins produced by a pet that triggers allergies in humans.
Pet dander is microscopic and can be moved around your home via house dust and even provides food for dust mites which feed off of skin particles leaving the bodies of human and animals. Even worse, when airborne dander can enter the open passages in your body like your nose, throat, and lungs causing allergies and in some cases more severe reactions due to the proteins found in the skin animals shed.
It also builds upon different surfaces and over time becomes a problem that never goes away and only gets worse. Don’t underestimate how hard it can be to deal with!
Opening a window lets in fresh air from the outside and can remove some odors and bring in clean air. The main problem with having allergens in an enclosed space is that they remain trapped there until removed.
Using an electric fan will not help and can actually trigger your allergies and disturb existing dust and pet dander causing more problems. Air fresheners do not actually remove odors and have no effect on contaminants in the air.
As allergens like pet dander and dust mite waste are incredibly small they’ll simply increase and increase until you can’t stand it anymore. The dust mite population will grow worse too since there’s so much pet dander for them to feed on.
A quality air purifier is what you need
As mentioned earlier, pet dander and other allergens are microscopic in size and permeate the air around you. The only true way to alleviate your allergies and keep your home clean and fresh is by removing the problem at its source.
HEPA filters are the answer
High efficiency particulate air (HEPA) filters are designed to provide a standardized level of filtering quality. The standard was introduced in the 1950s in the United States. Filters claiming to be “true” HEPA in quality are proven to satisfy to very strict requirements:
- Can remove 99.97% of particles from the air passing through them
- Are able to remove elements & substances down to 0.3 microns in size
(Note that 1 micron is 1/1,000,000 of a meter – incredibly small!)
HEPA filters are made of very dense material and they’re extremely efficient in removing nasty air particles. They’re so efficient that out of every 10,000 particles in the air that passes through them, only about 3 will be able to escape! The remaining particulates are permanently removed from your air forever.
Because of this and when implemented in well-designed, quality products they are capable of making a huge impact on your pet dander & allergy problems. The filtering process is accomplished by pulling air through the filter where these particles are trapped permanently – leaving only fresh, pure air in the surrounding air.
A true HEPA filter addresses the source of the problem – pet dander & dust carried in the air that can come in contact with your skin and enter your breathing passageways.
Additionally, good purifiers typically come with 1st & 2nd stage filters consisting of a more coarse filter for trapping larger elements like pet hair & large dust as well as a carbon/charcoal filter stage for trapping chemical substances in the air like odors.
Why not an ionizer or ozone generator purifier?
An ozone generator (shown here) can potentially produce high levels of ozone that may aggravate your breathing passages. Additionally, they don’t permanently remove particles like pet dander from the air around you. I don’t recommend them for pet dander problems. Stick with a proven and reliable filter-based product instead. You’ll be glad you did!
Other purifiers marketed work by generating ozone molecules from the surrounding oxygen molecules using a principle based on high voltage. The free molecules have an atomic charge which causes them to bond with particulates in the air.
Air purifiers sold as “ionizers” create electrical charges on air molecules to attract and trap airborne particles and kill airborne germs.
Many low-quality foreign made ozone generators are sold as “air purifiers” and “air cleaners” but in fact, both more often than not the unsafe levels of ozone have little to no impact on your air quality.
Some people may even experience headaches too as a consequence of being around ozone.

Product reviews and details
1. Winix HR900 Ultimate Pet – Best-in-class air cleaning and fantastic features make it the best choice for pet owners.
NEW! When it comes to keeping your home clean and fresh no matter how many pets you have, the Winix HR900 is in a class of its own. For around $200 you’ll get a lot for your money!
It’s not just full of great features the competition doesn’t offer – but one of the most advanced air filter systems money can buy. As a satisfied Winix air purifier owner, I’m happy to report they’re some of the best air purifiers I’ve tested & reviewed yet!
The HR900 offers not the usual 3 filter stages like most, but a fantastic 5 stages of purification:
- Pet filter screen
- Washable pre-filter (traps larger particles like pet hair and dust)
- True HEPA filter with 99.97% effective filtration down to 0.3 microns in size
- Advanced carbon odor control filter with solid pellets
- PlasmaWave stage ion pollutant cleaner
Unlike standard HEPA-based purifiers, the Winix is one of the most powerful air purifiers for dealing with pet dander & odors. It has one of the highest buyer satisfaction ratings with excellent reviews and many happy owners.
The PlasmaWave stage is a type of air molecule device which creates charged particles that attract and bond to viruses, bacteria, chemical vapors, and odors in the air.
Got a larger room? You’re covered as the HR900 is recommended for rooms up to 300 square feet in size.
Interested in the industry-standard Clean Air Delivery Rate (CADR) performance? I’m impressed with it, as the unit has lab-tested performance:’
- Dust: 200
- Pollen: 220
- Smoke: 194
That’s two times more effective air cleaning performance than many of the most commonly sold purifiers on the market today!
Filter system layout
The Winix HR900 uses a 5-stage filter system for excellent air cleaning performance. Not only is it a better performer, but the pre-filter and advanced odor control filter can be cleaned for extended performance. Access is really easy, too: Just open the magnetically-attached front cover and they’re easy to pull out.
One of the reasons I’ve awarded the HR900 my Editor’s Choice best buy badge isn’t just because of how well it works, but because maintenance is super easy.
Unlike the competition, the pre-filter and odor control filter can be removed and easily cleaned to keep performance high. Filters are really easy to remove, too! Just pop off the front cover (attached with a smart magnetic latch design) and pull out the pre-filter and odor control filter as needed.
Vacuum or rinse off the pre-filter and you’re done in seconds! After a heavy build-up of pet hair or dust, it’s a snap to clean and restore to 100% optimal operation.
Unlike most air purifiers on the market, the Advanced Odor Control (AOC) filter section is a powerful, highly effective approach to pet odor problems.
It contains real carbon pellets instead of the simple filter coating most use. Hands-down it’s one of the best money can buy – and you’ll get a lot longer life, too!
When it’s time to check, clean, and perhaps replace the filters the handy filter reminder will light so you won’t have to remember yourself.
Enhanced pet filtration included
Left: You’ll get a generous 12 included pet filters with the Winix for enhanced pet air cleaning needs. The pet filter extends the life of the HEPA and other filters. Right: Filter access is one of the easiest I’ve ever seen! The front cover features magnetic attachment points making maintenance incredibly easy.
One of the biggest advantages isn’t just the general design, but in fact the pet-specific filters it uses. Included with the purifier are 12 pet filters that easily attach to the pre-filter.
They work as a front line defense for capturing the toughest pet by-products and extending the life of the HEPA and other filters. Once used up, just remove and replace as needed.
Great controls and features
Top view of the HR900. Controls are easy to understand and operate. Just touch the push button electronic controls to rotate through fan speeds, turn off lighting, activate the auto-off timer, and even lock the controls in case you’ve got little kids.
Check out the excellent control features you’ll get for your money:
- Mode selection: Sleep, Low, medium, high, Turbo, and Auto speed modes
- PlasmaWave on/off button
- Power on/off control
- Auto-off timer control: Choose from 1, 4, or 8 hrs of operation
- Child lock: When set, controls can’t be changed by little ones
Auto mode automatically changes the purifier’s fan speed based on air quality. Don’t stress – you not only won’t have to get up and fiddle with controls, but just set it can forget!
Ready for sleep? No problem? Just put it in Sleep mode or Auto for a whisper-quiet operation that won’t disturb your rest. Winix has even added a light sensor to darken the controls when the lights are off as well!
Advanced air quality sensors and automatic operation mode
Included are 3 sensors for light & air quality self-adjusting operation: A light sensor, a dust sensor, and an odor sensor.
Anytime the air quality sensors detect you need more air cleaning power, the purifier automatically kicks into high gear and gracefully ramps up the fan speed until the air quality has improved.
For night-time use, the light sensor offers a smart way to switch off lighting to the display controls in order to keep it from annoying you in the dark.
Both sleep mode & and an off timer with 1, 4, and 8 hour shut off options are included, making it incredibly easy to “set and forget.” Both at bedtime and when you’re about to leave your home.
General quality and performance thoughts
For pet problems, I have to say the HR900 really impresses me. Odor control, pet dander, and pet hair filtering is excellent. It’s simply one of the best I’ve seen, yet you won’t go broke with the value you get at around only $200.
It’s a great choice for large rooms, it’s super-quiet, and I love the features. The auto-sensing mode works great and makes it a snap to use, even at bedtime. No need to touch the controls!

2. Levoit LV-PUR131 – A great purifier and an excellent value.
For less money than the Winix AC9500, the Levoit actually outperforms the Winix in room size coverage and features most of the same great features. It doesn’t include a remote control or additional germ killing features, however.
Levoit air purifiers are well-regarded and feature great design & a modern appearance too. The LV-PUR131 is no different. Electronic controls are simple to use (similar to its smaller sibling the LV-H132) and it includes a sharp-looking LCD display.
A lovely auto-off timer function with very flexible usage is built in: simply set the timer to shut off anywhere from 1 to 12 hours of operation.
An auto mode allows the unit to operate on demand as the air’s cleanliness drops and adjusts the fan speed automatically. 3 filtration stages remove pet dander and odors with a true HEPA filter for the best possible air purification for your money.
Filters are typically replaced about every 6 months and the replacement reminder will let you know when it’s time to check the filter. Expect to pay around $35 for a replacement, which is still relatively economical when compared to the Winix WAC9500 filter replacement cost which is nearly 60% more expensive.
A quiet sleep mode ensures that you’re not disturbed by noise as it provides a very low level of noise during operation. As it’s only about 11.2 lbs in weight and 14.5 x 7.2 x 18.5 inches in size, the PUR131 provides more square feet coverage (322 square feet) than the WAC9500 but can be placed on many countertops, shelves, and desks if needed.
A 2 year warranty is provided.
- More room coverage for the money (322 sq ft)
- Auto-sensing mode can be set to adjust fan speed based on air quality demands
- Sleep mode for very quiet operation
- Electronic, simple controls
- LCD display for auto-off timer
- Auto-off feature is very flexible: set anywhere from 1 to 12 hours for “set and forget” operation
- Great pet dander filtering with true HEPA filter and fine 1st stage filter; carbon filter removes pet odors
- Excellent overall reviews and customer satisfaction
- Lower weight and smaller size than the WAC9500 makes it suitable for use in more places
- 2 year warranty
- Nice, modern appearance
- No remote control
- Auto-sensing mode does not indicate air quality levels like the Winix WAC9500
- No night light
- No 5-stage filtering like the Winix WAC9500
- Replacement filters aren’t the cheapest (near $35 or so)
- Warranty is shorter than some competitors
As it’s a fantastic compromise between cost, room size coverage, features, and performance it’s a purifier you can’t go wrong with. Not only that, but it's a #1 best seller with wonderful reviews!
3. GermGuardian AC5250PT with Pet Pure treatment, germ killer, and auto-timer. A great all-around pet purifier!
The GermGuardian AC5250PT is a 28″ tall more advanced version of its popular sibling the smaller AC4825. Additionally it’s easy to use and features the same great build quality that has made the company’s air purifiers an industry standard.
A 3-in-1 filter assembly includes a true HEPA filter, a pre-filter, and a carbon filter to trap odors as well. The pre-filter is excellent for removing pet hair that carries allergy-causing dander as well. A Pet Pure anti-microbial agent is added to the filter for even more protection against mold, mildew, and odor-causing bacteria your pets produce.
The UV-C feature is an optional germ-killing bonus: when switched on, it safely bombards airborne microbes that pass through and render them inactive. It’s a great feature you won’t find on many competitors’ products.
The AC5250PT’s control panel is high-tech easy to read, but still simple to operate. For one thing, buttons are well-labeled and a breeze to understand. The color display readout shows the current fan speed and timer status along with other features at a glance.
The AC5250PT’s control panel is straightforward and features a nice status display with fan speed, UV germ killer on/off, and timer countdown. Electronic push button controls round out a nicely built and great-performing product you’ll be glad to own.

4. Hamilton Beach TrueAir Ultra – Affordable, compact, and quiet pet cleaning.
For those with a budget, the Hamilton Beach TrueAir represents a great buy. It’s well suited for desktops, shelves, and other convenient places. It’s a great choice if you have smaller pet dander problems.
It is simple to operate, using a rotary 3-speed fan switch yet still remains very quiet during operation unlike other lower-priced purifiers on the market. Even more beneficial is that the HEPA-grade filter is permanent and can be cleaned off for reuse – no replacement filters to buy!
Note that the pet-specialized carbon filter does need replacement, but a 3-pack of those costs less than $15, so it is still a very economical model.
It’s also small in size, measuring only 8.5 x 13.5″ yet provides coverage of up 140 square feet, so it is suitable for small rooms & offices. Due to its smart design, it can be turned on its side for use as well.
The included zeolite carbon filters are specially designed for pet odors while the HEPA filter removes pet dander from the air down to 3 microns in size (which is sufficient for all pet dander, dust mite allergens, dust, and much more).
The TrueAir’s filter is easy to clean for extended use (right). The purifier works great for a budget solution for pet issues. It’s great for small areas as well as it can be used both on its side or upright.
For the best cleaning & most expedient cleaning it can be set on high speed, medium for all-day cleaning, and low speed for the lowest noise possible.
- HEPA filter is very effective at removing pet dander in small rooms
