AprilAire Air Filter

This filter is designed for a 12-month replacement cycle. Because it is a high-capacity, whole-house filter, you only need to swap it out once a year to maintain optimal airflow and filtration performance.

Standard filters often allow air to leak around the edges, bypassing the filter media entirely. The patented self-sealing design creates a tight fit that forces all air through the filter, ensuring you are actually capturing the dust and allergens the filter is rated for.

This filter is specifically engineered for AprilAire whole-house air purifier systems, not standard 1-inch slot filters found in many residential HVAC units. Please verify that your system is designed to accommodate a 4-inch deep filter before purchasing.

Yes, with a MERV 11 rating, this filter is highly effective at capturing common household irritants, including pet dander, dust, and mold spores. It is a solid choice if you are looking to improve indoor air quality for allergy sufferers.

No tools are required. The filter uses an integrated rail system that allows you to slide it directly into your AprilAire housing for a quick, tool-free installation.

AprilAire guarantees that if you use their genuine filters as directed, they will cover the cost of cleaning your HVAC cooling coils if they become dirty within 10 years. It is their way of standing behind the filter's ability to protect your expensive HVAC equipment from debris buildup.
