Lennox X8790 MERV 16 PLEATED Furnace Filter 20x21x5 for PCO14-23

Atomic Filters have the size and quality(MERV 16) that I wanted at $50.00 per filter less than what my local furnace repair shop wanted. Next time I need another furnace filter the first place I'll look will be Atomic.

We ordered this as an experiment to see if we could get it to fit our Trane furnace. With some minor modification to the box to ensure a tight seal, it works nicely. We will be ordering more soon.
