Genuine Aprilaire 201 high efficiency replacement filter. Used the media air cleaner model 2200 and 2250. Aprilaire 201 is rated at Merv 10.
The 201 filter is 24¼" long and 6" wide with 39 fan-fold pleats. The filter requires assembly with 5 plasitic pleat spacers (not included).
Replacement is suggested once a year or after one heating and one cooling season. Holding the filter up to light will show the amount of dirt. Only the intake side should be dirty, the side of the filter that the air exits from should remain dust free.
