Our Top 5 Picks for the Best Pet Air Purifier

What is an Air Purifier?

An air purifier is a device that cycles your home's indoor air through a series of filters to trap and lock airborne contaminants. You switch it on, let it run, and it'll clean the air and expel the cleaned air back into your home until you switch it back off.

Your air purifier can come equipped with several different types of filters. Each filter has a slightly different function. Knowing the differences between the types of filters is key to helping you narrow down your choices.

Five Types of Air Purifiers

Now that you know how air purifiers work, well go over the five different types of air purifiers. This list will give you a good starting point to start searching for the correct air purifier to suit your needs. They include:

  • Activated Carbon - An activated carbon air purifier comes with an activated carbon filter installed. This filter is specially designed to help rid your home of odors by trapping the things that cause unpleasant smells like smoke or mold.
  • HEPA - One of the most popular types of air purifiers available are ones with True HEPA filters. True HEPA air purifiers can trap and lock 99.97-percent of any contaminants that come through because it has an extremely dense design.
  • Negative Ion - Negative Ion air purifiers use chemical injectors to rid your home's air of unwanted pollutants. They release negative ions that attach to any pollutants and weight them down to drag them out of the air.
  • Ozone - Ozone air purifiers release minuscule amounts of ozone into the air to change the pollutant's chemical makeup. However, the ozone it releases can actually contribute to your home's poor indoor air quality.
  • UV - The final type is air purifier comes with a UV light that destroys bacteria and germs as they pass through the light. They don't trap many particles or allergens though because they don't have a filtration system.

What to Consider When Buying an Air Purifier for Pets

There are several important things that you want to keep in mind when you're buying an air purifier. Keeping these things in mind will help to ensure that you get a quality air purifier that suits your needs.

Automatic Sensors

Air purifiers are starting to come with more and more technological features that make them more convenient for people to use. Newer models come with air quality sensors built right into the purifier that monitors your indoor air quality in real time.

As your air quality changes, the air purifier's sensors tell the air purifier this so it can adjust the speed it's running without any input from you. This is great if you plan to put your air purifier in an area that you don't frequent a lot or if you leave your purifier running while you're out and about.

Coverage Area

The first thing you have to understand is that air purifiers typically work best in the room where you have them running. Each air purifier will tell you the maximum amount of coverage area your specific device will cover without leaving any gaps in square feet.

You can get the square feet of your room by finding the length and width of the room and multiplying them together. The square footage of a 10 foot wide by 12 foot long room would be 120 square feet, and this calculator can help you find your room's square footage.

Ease of Use

Are you technologically savvy or do you need help when it comes to setting up your air purifier and maintaining it? You want to get an air purifier that is easy for you to switch on, turn off, adjust the settings, and set the timer if it comes with one.

Also, you want to get an air purifier that comes with a clean user face that allows you to adjust it quickly and easily. LED screens and other additional options like a light to remind you that you have to clean your filter are also other options.

Maintenance

How much time do you have to devote to cleaning your air purifier and how difficult is it to maintain? Some air purifies require you to take them apart and clean them while other air purifiers require you to switch out the filter every six to eight months.

Additionally, ionizers and UV air purifiers will most likely require more routine maintenance to keep them running in peak performance because there are no filters. Are extra filters expensive and how difficult is it to get them? These are all things that you want to keep in mind.

Noise

Since you run these air purifiers 24 hours a day, you want one that is very quiet. You want to look for quiet operation, and it's important to note that air purifiers with fans can run a little louder on their more powerful settings.

Unfortunately, you won't really be able to test your particular device's noise levels unless you buy it in person. However, you can usually read reviews to get a good idea on how well something runs, and certain air purifiers come with quiet run technology to make them virtually silent on every setting.

Power Consumption

You want an air purifier that is very energy efficient because most people leave them run 24 hours a day. The last thing you want is to run an air purifier and have it drive your energy bill up.

It's important that you look for an air purifier that comes with an energy star rating. This energy star rating will help to reassure you that your air purifier is between 10 to 20-percent more energy efficient than any non-rated model, and this can save you money all year round.
