Aprilaire 213 Replacement Whole-House Air Filter 20x25x4 (Pack of 2) — MERV 13 Self-Seal for Allergy & HVAC Protection

The AprilAire 213 is a genuine MERV 13 whole-house replacement filter engineered to trap common allergens and fine particles while fitting precisely into AprilAire air purifiers.

Designed and manufactured in the USA by AprilAire, the 213 replacement filter uses the brand’s Self-Seal™ design to create an airtight fit and reduce bypass around the media. This high-performance MERV 13 filter captures a wide range of airborne particles—pollen, mold spores, pet dander, dust, dust mite debris, and many fine particulates—to help lower in-home contaminants and reduce cleaning frequency. AprilAire pairs this filtration with a 10-year Clean-Coil Commitment to help protect your HVAC coil with proper maintenance.

How effective is the AprilAire 213 at removing allergens and fine particles?

The AprilAire 213 meets MERV 13 performance standards and is independently verified to remove a high percentage of common allergens and virus-sized particles in controlled testing. It captures up to 97% of typical allergens and shows strong performance versus submicron particles, improving indoor air quality when installed and replaced per guidelines.

• MERV 13-rated media captures particles down to the 0.3–1.0 μm range.
• Independent lab testing confirms improved removal of harmful particles versus minimum MERV 13.
• Designed to remove pollen, pet dander, mold spores, dust, and many fine particulates.
• Pack of two filters for easy scheduled replacement.

How long will a 213 filter last and how often should I replace it?

The AprilAire 213 is built for long life and low maintenance under typical residential conditions. AprilAire recommends changing the 213 at least once a year to keep your whole-house purifier operating optimally and to preserve HVAC system performance.

• Rated for up to 12 months of typical service life.
• Longer media life reduces frequency of replacements and operating strain.
• Annual swap helps maintain filtration efficiency and system protection.

Does the AprilAire 213 affect energy use or HVAC performance?

• Engineered media for extended life compared to lower-rated filters.
• Fewer replacements mean less waste and lower lifetime cost.
