The Koch Multi-Pleat XL13 MERV 13 furnace filter is a high performance disposable replacement air filter for all gas and oil furnaces, heat pump and AC air handlers that use a 20 x 22 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 13 rated filter will be an upgrade compared to your previous filter. The size of the P13M12022 replacement air filter is approximately 19 1/2" x 21 7/8" x 3/4".
The Koch Multi-Pleat XL13 MERV 13 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 13 efficiency with low resistance to airflow. It is also unaffected by high humidity and is hydrophobic (non-moisture absorbing). Koch Multi-Pleat XL13 air filters can upgrade existing flat panels as well as MERV 6 & 7 pleated filters currently being used with little increase in resistance. Diagonal and horizontal support members provide frame strength and the filter media pack is sealed to eliminate air bypass. The Koch Multi-Pleat XL13 filters are UL 900 Class 2 listed.
The Koch P13M12022 air filter media should be checked every month. Adjust the schedule to your needs, but at least replace the filter every three months.
For instructions on how to change your furnace's air filter, please refer to your unit's Owner’s Manual.
