Finding the Best Air Purifier for Pets

There are a handful of factors you need to consider when picking out the best air purifier for pets. We discuss these crucial factors below.

Speed Setting

It’s vital to pick up a model that offers plenty of speed settings so that you can adjust it based on your requirements. On the lower settings, the device will be quieter and use less energy. However, if the air in your home is particularly smelly or dirty, you can turn up the settings to remove odors and allergens quickly.


There are a few design options to consider when you’re picking an air purifier for your lovely pets. These include:

  • Closed back panels: These models have a closed back design, or their entire housing is covered to protect advanced equipment featured in the purifier.
  • Tower design: Tower air purifiers feature a slim design that allows you to easily place these products in any location in your house.
  • Wall-mounted: These versions can be mounted onto a wall in your home, and they work by taking in the polluted air from the bottom and pumping out fresh air from the top.

Electronic Filter Monitors

Every air purifier relies on the use of a filter to maintain the consistency of the purification process. These filters need replacing from time to time, and some models come with the feature of offering alerts every time your filter needs to be replaced.

Automatic Operating Mode

This is a feature that is often found only in premium models. It gives the air purifier autonomous control to be able to regulate the airflow based on the requirements of the room. Although you’ll have to pay a considerable amount for this feature, it’ll save on electricity in the long run as the purifier operates at its most efficient in this mode.

Remote Control

Some models include remote controls that let you change the settings of the purifier from any location in your house. It isn’t the most vital feature, but it can be handy when you own a large home.

UV Bulb

UV light has been known to have powerful sterilizing abilities and can be extremely lethal to airborne pathogens such as microbes, bacteria, and viruses. A few models come with the option of a UV bulb that can be extremely useful in doubling the safety of your home.

Ion Generators

Models that include ion generators are known to be some of the best air purifiers on the market. This feature uses negative ion-charged particles that stick to one another and eventually create a massive particle cluster. These clusters fall to the floor or stick to the nearest surface after that, allowing you to clean them easily.

This is a handy feature to seek out in air purifiers and is a brilliantly effective method of removing unnecessary particles from your home.

Off Timer

Air purifiers are notoriously power-hungry devices that tend to eat up a lot of electricity when left running for extended periods. Having an off-timer on your device is a great way to save power, especially when you want to use the device only for a few hours before dozing off.


Some good purifiers for pet owners come with a humidifier function, it helps to control the humidity at the same time. Check our picks for the best humidifier and purifier combos.

Keep It Pure

Air purifiers are not only known to be extremely useful for human beings, but they are also quite priceless to have around when you have pets at home. They can help control odors, remove dander, and keep the house smelling nice and fresh.

All six models recommended on our list would make excellent purchases. While the Coway Airmega 400 Smart Air Purifier is ideal for large spaces over 1500 square feet, the Alen BreatheSmart Classic Large Room Air Purifier is ideal for keeping a check on stray odors. 

The LEVOIT H13 Purifier, however, has to take the cake for being the best air purifier for pets around today. It’s a small and handy device that is virtually noiseless and can eliminate nearly 99.97 percent of all impurities in a given space. 

You’ll never have to worry about your room’s air quality with your pet around thanks to this highly useful gadget.
