The Koch Multi-Pleat XL8 MERV 8 furnace filter model P8S1-170-250 is a high performance disposable replacement air filter for all gas and oil furnaces, heat pump and AC air handlers that use a 17 x 25 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 P8S1-170-250 replacement air filter is approximately 16 7/8" x 24 1/2" x 3/4".
The Koch Multi-Pleat XL8 MERV 8 Pre Pleat 40 disposable air filters feature 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). Koch Multi-Pleat XL8 air filters can upgrade existing flat panels as well as MERV 6 & 7 pleated filters currently being used with little increase in resistance. All Multi-Pleat XL8 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 Koch Multi-Pleat XL8 filters are UL 900 Class 2 listed.
The Koch P8S1-170-250 air filter media should be checked every month. Adjust the schedule to your needs, but at least replace the filter every three months.
