AprilAire 310 Replacement Filter for AprilAire Whole House Air Purifiers - MERV 11, Clean Air & Dust, 20x20x4 Air Filter (Pack of 1)

The Aprilaire replacement air filter is a high-quality MERV 13 option for whole-home air purifiers that effectively captures allergens and pollutants. The filter has received positive feedback from customers who have found it to be effective in reducing allergies and respiratory issues. However, some customers have reported whistling sounds coming from their units, and it is recommended to ensure the filter is correctly seated to address this. Another concern is that there is no carbon version for 20"x 20" filters that remove cooking odors and VOCs. The team at Aprilaire recommends reaching out to local HVAC contractors to ensure proper sizing for individual systems. Overall, the Aprilaire replacement air filter serves as an effective option for improving indoor air quality in homes, but customers must ensure that it is the correct size and properly installed for optimal performance.
