An air purifier for pets is a handy appliance that can transform the atmosphere of your entire home, especially if you keep pets.

Air purifiers come with powerful electric fans that combine with high-efficiency filters to eliminate dust mites, airborne bacteria, allergens, mold spores, pet dander, odors, and even smoke, from multiple rooms in your home.

Some purifiers will run for the entire day or night to keep your home’s air fresh and safe for your entire family.

In our top 10 air purifiers for pets’ review, we help you choose a model that best fulfills your household demands.

What To Check Before Buying Air Purifier for Pets?

How to Buy the Best Air Purifier for Pets

1. Power

Your air purifier is an electric appliance that will consume some degree of power during operation.

If you’ll be running your purifier for extended periods, such as the entire day and night, then a low-power one will help keep energy costs at the minimal.

Some pet air purifiers we saw that consume low power in their lowest speeds include Koios EPI810-A and Levoit Vista 200.

It’s worth noting that power consumption may increase with an increase in air purifier fan speed.

2. Speed Settings

Air purifiers for pets have varying fan speeds. The speeds determine how much air is discharged from the unit into the surrounding environment.

Most air purifiers have at least 2 speed setting, with many having 3 (high, medium, and low). However, models such as the Guardian Technologies AC5250PT did stand out from the rest because of its 5-speed settings, which make the purifier more versatile.

Often, you may not reach the highest fans speed as even low-speed settings are very reliable.

3. Filtration

Filtration systems are key components of air purifiers. All purifiers have filtration systems with one or more stages.

The most reliable air purifiers for pets have multi-stage purification systems. Almost all the models we reviewed had 3 or more filtration stages. A 3-stage filter often has a HEPA filter, an activated carbon filter, and a normal filter.

However, some models have a superior filtration system, like the Renpho RP-AP001 and Hathaspace HSP001, both of which have 5-stage filtration systems.

4. Coverage Area

Coverage area is another important consideration to make when choosing an air purifier for pets.

If you want a purifier for large spaces such as offices and living rooms, get one that covers a large area.

Blueair Pure 211+, Honeywell HPA300, and Whirlpool AP51030K are some of the models we reviewed, which cover areas of over 400 square feet.

You can also get purifiers that cover smaller spaces, in case your room is not so big. Such purifiers are likely going to consume less power.

5. Noise Level

Air purifiers have fans, which produce varying degrees of noise depending on their speed.

Most users will prefer an air purifier which runs as quietly as possible, especially at night when people are sleeping. Noise can be a nuisance and sleep disrupter.

Luckily, most of the air purifiers we reviewed run quietly, especially at low speeds. Hathaspace HSP001 is one such air purifier with a noise level of 18 dB at its lowest speed setting. Other worthy mentions are Levoit LV-PUR131S and Levoit Vista 200, which have noise levels below 30 dB at their lowest speeds.

6. Remote Control

You may also encounter air purifiers for pets, which have remote control functions to support simplifies and flexible operation.

If your air purifier has a remote control, you are able to set timers, monitor air quality, switch the purifier on or off, and adjust fan speeds.

Hathaspace HSP001 has a remote-control option, which is achieved through an app you can install on your phone.

7. Ease of Use and Maintenance

Air purifiers are appliances constantly exposed to a great deal of dirt and allergens, thus requiring regular maintenance.

Much of the maintenance done on air purifiers for pets involves replacing air filters. The frequency of filter replacements will depend on your purifier model, the number of filters, and the intensity of appliance use.

The ease of use depends on the purifier design and control layout. Whirlpool AP51030K is one such air purifier designed for ease of use.

Another thing to love is its ease of operation. You only need one button to get it running. A nightlight function is included to illuminate rooms and paths.

Blueair Pure 211+ emerges as the best pet air purifier for large rooms with its superior coverage area.

This air purifier covers an area of up to 540 square feet, which is the largest we have recorded in all the models reviewed here. If you have a large living room, bedroom or even office space needing a constant supply of clean and fresh air, this is the purifier for you.

It also boasts of an advances Swedish filter design, which promises to capture 99% of airborne pollutants and pathogens, including pollen, dust, pet dander, bacteria, mold, and a wide range of viruses.

Producing only 31 dB of noise at its lowest speed, this unit is notably quiet and is no louder than a whisper.

You also get 2 machine-washable fabric pre-filter, which come in dark shadow and diva blue colors. These colorful pre-filters make the whole unique elegant.

The unit comes with HEPA filters, which trap 99.9% of allergens, including dust mites, pollen, and pet dander. An antimicrobial agent, Pet Pure, has also been added to the filter to prevent mold growth.

Filter replacement is a bit pocket-friendly with this purifier. Only one filter requires replacing every 6-8 months, depending on operating conditions.

A digital display panel is included to simplify the control of the purifier. It contains a filter change indicator, timer, and UV C controller.

An issue we did not like in the Guardian Technologies AC5250PT is its small coverage area of only 180 square feet, which makes it unsuitable for large rooms.

The purifier’s CARB-certified and Energy Star-certified air filter is versatile and capable of capturing dust, pet dander, smoke, odors, and allergens.

It is also incredibly quiet. You’ll barely hear it running with its 27-dB noise level. It maintained the peace and quiet in your environment even as you sleep.

You also get a Sleep Mode function, which allows the purifier to run at a low fan speed thus producing low noise levels of 26 dB only.

Warm night light with 2 brightness levels is a handy feature offered by this purifier to stimulate sound sleep. We didn’t like the fact that the Levoit Vista 200 covers a small area of 161 square feet only.

This purifier especially excels in protecting you and your family from allergies caused by pet dander and other allergens including pollen, dust, smoke and other particles as small as 0.3 microns.

A cost-saving feature you’ll love is the separated filter replacement function and indicator. When the appropriate filter light flashes, you can replace the respective filter without removing all the other filters.
