Common Questions

How often should the Aprilaire 401 filter be replaced?
Replacement intervals depend on the specific indoor environment and total system run time; however, contractors typically recommend a change-out every 6 to 12 months to prevent excessive static pressure.

Is the 401 media interchangeable with newer high-efficiency upgrades?
The Model 401 is the standard MERV 10 media. If a higher MERV rating is required, ensure the system blower motor is rated for the additional resistance before upgrading.

Does this filter include the metal spacers?
No, this is the replacement media only. The existing plastic or metal spacers from the original housing must be reused to secure the pleats in place.
