Aprilaire 201 MERV 10 Furnace Filter 20x25x6 — 2-Pack, 12-Month Pleated Whole-House Replacement

The AprilAire 201 replacement furnace filter is a MERV 10, 20x25x6-inch whole-house air filter designed to capture common airborne particles and fit AprilAire or Space-Gard 2200 and 2250 air purifiers.

When indoor air quality matters, choosing the right furnace filter makes a noticeable difference. The AprilAire 201 is a six-inch deep, pleated filter engineered to trap dust, pollen, mold spores and pet dander as air moves through your system. Sold as a convenient two-pack, these filters are built to last up to 12 months, reducing how often you need to change them compared with standard one-inch filters.

How does the AprilAire 201 improve my home's air?

By offering MERV 10 performance in a deep-pleat design, the AprilAire 201 captures a broad range of airborne particles without heavy restriction to normal airflow. Its larger media area lets it hold more contaminants between changes, helping maintain cleaner ducts and indoor surfaces.

• MERV 10 efficiency removes dust, pollen, mold spores and pet dander
• 6-inch depth increases filter media surface area for improved particle capture
• Pleated construction prolongs service life up to 12 months under typical conditions
• Two-filter pack ensures you have a replacement ready when needed

Will this filter fit my AprilAire or Space-Gard unit?

The AprilAire 201 is made to be compatible with AprilAire and Space-Gard whole-house air cleaner models 2200 and 2250. The listed size uses the industry’s nominal dimensions (20 x 25 x 6 inches) to help you find the right replacement without measuring exact frame tolerances.

• Nominal size: 20 x 25 x 6 inches — match nominal sizing to your existing filter
• Designed specifically for models 2200 and 2250 air cleaners
• Packaging includes step-by-step replacement instructions for easy installation

How often should I replace the AprilAire 201 filter?

AprilAire recommends replacing the filter annually for typical residential use, thanks to the deeper 6-inch media that holds more debris than thinner filters. Homes with pets, high dust, or allergy concerns may require more frequent checks and possibly earlier replacement to sustain airflow and filtration efficiency.

• Typical service life up to 12 months under normal household conditions
• Check sooner in homes with pets, smokers, or heavy dust loads
• Regular replacement helps protect HVAC components and can help maintain efficiency

Is there an upgrade option for better performance?

If you want higher particle capture or a different frame system, AprilAire offers the Model 1213 upgrade kit. That kit converts the original 201 filter frame to accept a higher-performance 213 filter and removes the need for pleat spacers, simplifying future filter changes.

• Model 1213 upgrade kit (sold separately) replaces 201 with 213 high-performance filter
• New frame system eliminates pleat spacers for easier installation
• Good route for users seeking enhanced filtration without replacing the entire air cleaner

Who is this for? The AprilAire 201 two-pack is suited for homeowners and renters using AprilAire or Space-Gard 2200/2250 whole-house air purifiers who want reliable, year-long filtration with a balance of particle capture and system airflow. Choose this pack if you want American-made replacement filters that reduce maintenance frequency, protect HVAC components from dust buildup, and fit existing AprilAire/Space-Gard systems. If you need stronger filtration or a frame upgrade, consider the AprilAire 1213 kit or the 213 filter as an alternative.
