Frequently Asked Questions

How often should I change my Aprilaire 231 Filter?

Depending on the air quality in your home, you may need to change the Aprilaire 213 filter every 9 to 12 months. If you have smokers or pets in your home, you will likely need to replace it more frequently to keep your air purity at an optimal level.

Where can I buy an Aprilaire 213 filter?

The Aprilaire 213 is readily available to customers directly through the manufacturer, or you can find it on Amazon or Walmart when it is in stock.

Which Aprilaire filter is better – 210 or 213?

One of the most important ways to compare the Aprilaire 213 to similar air filters is by checking the Minimum Efficiency Report Value (MERV) and deciding what rating is best for your space. MERV is a rating that indicates the size of the particles the filter is designed to capture. The Aprilaire 213 filter is rated a MERV 13, while the 210 is a MERV 11. This means the Aprilaire 213 filter can grab smaller particles than the 210. It can also trap virus-sized particles and bacteria from the air, even if they are smaller than 1.0 micron in size. The 210 is not manufactured with a MERV rating high enough to hit these levels. All in all, the Aprilaire 213 operates more efficiently than the 210 and has a better chance of removing the smallest particles from the air.
