How does this filter reduce dust and airborne allergens?

The AprilAire 110 uses MERV 11-rated media to trap a broad range of particles as household air passes through the filter, reducing what settles on floors and surfaces. Its thicker 4-inch design provides more filtering surface than common 1-inch filters, increasing capacity and efficiency.

• MERV 11 captures pollen, pet dander, mold spores, and larger bacterial particles
• 22.2 sq ft of filtering media for higher dust-holding capacity
• 4-inch depth extends service life up to 12 months under typical residential use

Will this filter fit my AprilAire system and is it easy to replace?

This is a genuine AprilAire replacement specifically sized for AprilAire air cleaner model 1110 and uses the brand’s interlock rail system for straightforward swapping. The filter arrives ready to install—no assembly, reinforcements, or special tools required.

• Nominal size: 16 x 20 x 4 inches to match AprilAire filter listing
• Patented Interlock Rail System: slide in and close—simple three-step replacement
• Illustrated packaging includes step-by-step replacement instructions

How does the filter protect my HVAC and energy efficiency?

The AprilAire 110 limits particle buildup inside your ductwork and on heat exchangers, which helps systems run more efficiently and may reduce maintenance frequency. Low initial resistance and high dust capacity support steady airflow while capturing contaminants before they reach sensitive components.

• Self-Seal Technology prevents bypass so air goes through the media, not around it
• Lower dust accumulation inside equipment helps sustain system efficiency
• Up to 12 months of life reduces replacement visits versus 1–3 month filters
