Aprilaire 3" Filters with TRIPure Media

AprilAire 4-Inch Filters Are Transitioning to 3-Inch Replacements

AprilAire is introducing a new generation of 3-inch replacement filters for many existing whole-house air cleaners. If you currently use an AprilAire 4-inch filter, this guide will help you identify the corresponding 3-inch replacement and plan for the change.

Your existing air cleaner can continue to be used with the compatible new filter, but a one-time upgrade to the filter rail system may be required. Check the replacement details before ordering.

Why AprilAire Is Introducing the New 3-Inch Filter?

AprilAire is transitioning from its longstanding 4-inch filter design to a new generation of 3-inch replacement filters featuring TriPure media technology. The new design is intended to provide effective whole-home air filtration with improved airflow and longer-lasting performance.

For homeowners with compatible AprilAire air cleaners, this means a change in the replacement filter they purchase-not necessarily a change to their existing air cleaning system. A one-time upgrade to the filter rails allows the new 3-inch filters to be used in compatible existing equipment.

What Changes With the New 3-Inch Filters?

While the new filters are thinner than the original 4-inch versions, AprilAire has introduced several changes intended to improve filtration performance and simplify maintenance.

  • New 3-Inch Design: Replaces the existing 4-inch filter format in compatible AprilAire whole-house air cleaners.
  • Updated Filter Media: TriPureT technology is designed to capture common airborne particles, including dust, pollen, and lint.
  • Improved Airflow: AprilAire reports up to 30% lower airflow resistance compared with certain competing filters under controlled testing conditions.
  • Long-Lasting Filtration: The new filters are designed to last up to 12 months, depending on operating conditions.
  • One-Time Rail Upgrade: Compatible existing air cleaners require an upgrade to the filter rail system to accommodate the new 3-inch design.

Important: Before ordering, use the replacement guide above to identify the correct 3-inch filter for your existing AprilAire air cleaner.

Reduce Airborne Contaminants Throughout Your Home

Keeps your air cleaner by removing more pollen, household dust, and lint than leading brands and helps reduce your exposure to pollutants linked to higher rates of heart disease, stroke, and other serious health risks.
