- UNIVERSALLY COMPATIBLE: MERV 11 Pleated Air Filter for HC HVAC or Furnace (Pack of 4 Filters), comparable to MPR 800 / 1200. Actual size is: 19-3/4 x 24-3/4 x 3/4
- A CLEANER ENVIRONMENT：Say goodbye to dust, pet dander，pollen, dust mite, debris, lint, mold spores, smoke, smog, and auto exhaust particulates. Say hello to better indoor air quality!
- LONG-LASTING: For best results, change the filter every 60 to 90 days during normal times of the year, but increase the frequency to 30 days during peak months of summer and winter, when the equipment is most difficult to work with. They are very easy to replace and can be changed more often for homes with children or those who suffer from allergies.
- HIGH QUALITY: Moisture-resistant clay coated frame, which stays strong through humidity and temperatures up to 180° F (81℃). Pleated filters deliver multiple benefits – greater surface area means more air coverage, thicker for great capture capacity, and extended life for your AC or furnace.
- ADVANCED TECHNOLOGY: Low initial resistance requires less energy consumption, resulting in lower operating costs and energy savings.
