Aprilaire 216 Replacement Filter – MERV 16 for Whole-Home Air Purifiers (20x25x4) – Pack of 1

Upgrade Your Home Air with a Genuine Aprilaire 216 Filter

The Aprilaire 216 Healthy Air filter is designed to slide into compatible Aprilaire air purifiers, turning air moved through your HVAC system into a cleaner, more balanced breeze in everyday life. The 4-inch depth delivers a larger filtration area than standard options, supporting longer intervals between changes while maintaining strong airflow.

What the 216 Can Do in Real Homes

In many homes, daily activity stirs up pollen, dust, pet dander, and other irritants. The 216 filter works through the purifier to reduce this mix as air circulates, potentially lowering the presence of pollen, spores, bacteria, and smoke particles. The filter’s high-efficiency media helps capture virus-size particles and other common pollutants while your HVAC system continues to run smoothly, which may contribute to a more consistent indoor climate and less frequent dust buildup on surfaces.

• Virus-size particle capture up to 98% in tested conditions
• Allergy and asthma trigger reduction through high-efficiency filtration
• External air bypass minimized by Self-Seal Technology for better filtration efficiency
• Easy 3-step replacement using the Interlock Rail System

Design and Longevity

With 28 square feet of filtering media, this 4-inch filter provides substantial surface area for particulates, helping maintain airflow while collecting more contaminants. The combination of low initial resistance and high dust-holding capacity often supports longer intervals between changes, compared with thinner filters.

• Nominal size 20 x 25 x 4 inches, compatible with multiple Aprilaire models
• Four-inch depth delivers expansive media for heavy-use environments
• Estimated life up to six months under typical home conditions

Genuine Aprilaire filters are made in the USA and designed to fit the purifier exactly. The Pure Fit Promise and Self-Seal Technology help ensure air passes through the intended media, supporting your system’s performance and your home’s air quality.
