Frequently Asked Questions

Use our Filter Conversion Guide to find the correct TriPure™ Filter with one-time upgrade rails for your AprilAire Whole-House Air Purifier model.

The upgrade rails are a one-time installation that allows your existing air purifier cabinet to work with the new TriPure™ Filter platform. In addition to enabling compatibility, the new easy-glide rail system makes future filter replacements faster and easier by allowing the filter to slide smoothly into place every time. Once installed, no additional rail changes are needed for future filter replacements.

Every Upgrade Kit includes one-time upgrade rails that must be installed before using the new TriPure™ Filter. Watch our step-by-step installation video here.

While your new TriPure™ Filter may look different and be a different thickness than your previous AprilAire Filter, it was specifically engineered to deliver improved performance through advanced filtration media rather than relying on filter depth alone. TriPure™ Technology provides enhanced filtration performance, lower airflow resistance to help support HVAC system efficiency, and up to 12 months of filter life. This allows the filter to deliver better overall air purification while maintaining the convenience of annual replacement.

Yes, new TriPure™ Filters are designed to fit all AprilAire 4″ and upgraded 6″ whole-house air purifier cabinets. Compatible systems can use the new TriPure™ Filter with the included upgrade rails. No air purifier cabinet replacement is required. View the filter conversion guide here to find your model.

MERV (Minimum Efficiency Reporting Value) serves as a test designed to minimize confusion about the performance of air filtration devices by assessing the minimum or worst-case scenario for a product’s effectiveness.

The test evaluates an air filter’s efficiency across three particle size ranges: large particles (3.0 – 10 microns), medium-size particles (1.0 – 3.0 microns), and small particles (0.30 – 1.0 micron). While two products may share the same MERV rating, variations exist in terms of initial particle size efficiency, initial air resistance, air leakage, bypass air, service life, and tested airflow.

The standard requires the test to be conducted at 1200 CFM (Cubic Feet per Minute). However, not all manufacturers adhere to this condition, and reduced airflow can inflate an air filtration device’s MERV rating. It’s essential to note that MERV solely assesses immediate performance, and a product may exhibit a lower MERV as it begins filtering particulate matter. The MERV test also employs test dust containing carbon.

An AprilAire Air Filter plays a crucial role in your HVAC system, trapping dust and other airborne pollutants that can pose health risks or lead to HVAC system issues. As the filter accumulates debris over time, its efficiency diminishes, making it essential to replace it for optimal system performance.

Follow these tips for proper air filter disposal:

  1. Turn off your HVAC system before removing the old filter. Running the system without a new air filter is not recommended.
  2. Have a plastic bag ready to contain the dust, debris, and contaminants from the old filter.
  3. Avoid shaking or bumping the filter during the disposal process.
  4. Tape the bag securely to prevent any spills or leaks.
  5. Place the sealed bag with the old filter in an outdoor trash can to prevent the escape of dirt and debris back into the indoor air.
  6. Insert the replacement Aprilaire Filter into the HVAC system and then turn the system back on.
  7. Ensure you have a replacement Aprilaire Air Filter on hand for future replacements.

Simplify the process by ordering a new Aprilaire Air Filter today. For additional information and tips on Aprilaire Air Filters and Purifiers, explore our FAQs article.

Annual maintenance is recommended and includes replacing your air filter. It is simple and takes less than a minute. No tools, washing, or vacuuming required. Your Healthy Air Professional may suggest replacing it sooner or later depending on your unique home.
