3 minute read

Have questions about AprilAire Air Purifiers or AprilAire Filters? These are some of the most common inquiries we receive, but if you require additional assistance or information about the best air purifier, please contact our talented and knowledgeable customer support team!

What is MERV, and how do I know which AprilAire Filters I should use? How often should my AprilAire Filters be replaced?

MERV, or Minimum Efficiency Reporting Value, ranks air filter efficiency. The higher the MERV rating, the better it is at cleaning your air!

The filter you choose depends on what you want to tackle in your home. Here’s a guide to help you find the right AprilAire Filters for your needs.

MERV 10, 11, or 13 AprilAire Filters should be changed annually; however, if you run your fan 24/7, check your filter every six months as it may need to be replaced earlier.

MERV 16  and 13 + Carbon AprilAire Filters should be changed every six months. While these are just recommendations, some filters may need to be changed more or less often than others.

How do I know when my filter is dirty and needs to be changed?

Replace AprilAire Filters when the color of the filter changes from bright white to dark gray. If you see dirt starting to cake on the outside of your filter, it should be changed immediately. Typically, it’s standard to replace AprilAire Filters every 6–12 months, saving you time and money compared to traditional 1-inch filters, which require replacement every 1–3 months.

It’s important to note that some thermostats can be programmed to display reminder notifications to help you know exactly when to swap out your filter. Check with your local Healthy Air Professional to learn more.

What are AprilAire Filters made of?

Our 6-inch filters are microglass, while our 4-inch filters are polypropylene.

How do I know which AprilAire Filters to buy for my air purifier?
