The Flanders PrecisionAire MERV 8 furnace filter model 80085.011820 is a high performance disposable replacement air filter for all gas and oil furnaces, heat pump and AC air handlers that use a 18 x 20 x 1 air filter. This filter should have the same if not higher efficiency rating as the original equipment manufacturers air filter media. In some cases this MERV 8 rated filter will be an upgrade compared to your previous filter. The size of the 80085.011820 replacement air filter is approximately 17 3/8" x 19 1/2" x 7/8".

The Flanders PrecisionAire MERV 8 Pre Pleat 40 disposable air filters features a filtering medium that is more efficient and ecologically friendly than most other air filters on the market. Made entirely from recycled materials, this medium achieves MERV 8 efficiency with low resistance to airflow. It is also unaffected by high humidity and is hydrophobic (non-moisture absorbing). Flanders PrecisionAire Pre Pleat 40 air filters can upgrade existing flat panels as well as MERV 6 & 7 pleated filters currently being used with little increase in resistance. All Pre Pleat 40 filters are 30-35% efficient by ASHRAE 52.1-92 and MERV 8 per ASHRAE 52.2-99. Diagonal and horizontal support members provide frame strength and the filter media pack is sealed to eliminate air bypass. The Flanders PrecisionAire Pre Pleat 40 filters are UL 900 Class 2 listed.

  • Media: 100% Non-woven synthetic non-moisture absorbing media manufactured from recycled material with a MERV 8 efficiency rating and a UL 900 Class 2 listing
  • Media Support: Diamond-shaped expanded metal
  • Pleat Design: V Pleat
  • Frame: Moisture-resistant clay coated frame made with recycled material

The Flanders 80085.011820 air filter media should be checked every month. Adjust the schedule to your needs, but at least replace the filter every three months.
