Choosing the best Air Purifier for your Home

How clean is the air you breathe?  It’s a question on many people’s minds as seasonal allergies will start to wreak havoc across the continent. Several of your home appliances can help reduce pollen and pollutants in your home, but an air cleaner/purifier is your go-to product if you want to improve the quality of the air in your home.

Even if you don’t suffer from seasonal allergies, air purifiers can help make your living space cleaner and more comfortable, and some models (those with carbon filters) can reduce odors.

How do air cleaners remove pollutants from your home’s air? It depends on the model. Some air cleaners use a combination of filters (HEPA and ULPA) and fans, electrostatic filters that clear the air by using static to attract particles, electrostatic precipitators that attract particles to a plate or grid, or ionization combined with other technologies. Many units also have pre-filters that trap larger particles.

On a given model, you might also find multiple features, including:

  • Multiple power settings
  • Oscillation, including some with multiple levels of oscillation
  • Sensors: Some air cleaners have the ability to sense the air quality and adjust the fan speed accordingly
  • WiFi capability

Make the right choice

With all of the models and features available, how do you choose the right air cleaner for your home? The most important detail to know is the size of the room in which the air cleaner will primarily be used. Look for the AHAM Verifide® label, which will show the air cleaner’s Clean Air Delivery Rate (CADR) and suggested room size.

CADR is a measurement of how fast an air cleaner filters three commonly sized particulates: dust, pollen and tobacco. The higher the number on the label, the faster the air cleaner filters the air. However, don’t just choose the air cleaner with the highest numbers. You might end up with one that is too large for the room, leading to unnecessary energy use and noise. A too-small model may not get the job done. Follow the 2/3 rule, and choose an air cleaner with a tobacco smoke rating that is two-thirds the size of the room’s area. That means a room that is 200 square feet, would require an air cleaner with a CADR for tobacco smoke of at least 132.

CADR also gives you a way to choose an air cleaner based on your air cleaning needs. If you live in an area with a high pollen count, consider air cleaners with higher ratings for filtering pollen. If dust is an issue, pay closer attention to the unit’s rating for dust.

CADR is a recognized performance testing program where air cleaners are randomly selected and tested at an independent laboratory using the American National Standard, known as ANSI/AHAM-AC-1.

You will find the AHAM Verifide® label with the CADR ratings on the product packaging.

After purchasing 

Now that you have an air cleaner that is right for your home, it is time to maximize its air cleaning potential. 

Position it properly:  Air cleaners work best when they’re put in a place that allows them to filter as much air as possible. Certain air cleaners, depending on the design, aren’t as effective if placed in the corner of a room. Place the air cleaner closer to the center of the room, away from anything that may block or obstruct the air flow.

Clean it regularly: This applies to both units with filters and those that use electrostatic precipitators. Change the filter according t0 recommendations in the appliance’s use and care manual. If you use the air cleaner frequently or in areas with higher levels of pollutants (like where the pets hang out), you likely will need to change it more often. Precipitators also need to be cleaned regularly. A drop in performance may signal that it’s time to change the filter or clean the precipitator.

Use your other appliances: Vacuums, central vacuums, clothes washers and dryers, air conditioners and dehumidifiers are all part of the equation to keep the allergens in check in your home.
