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

Atomic filters are a money saver if you have HVAC and other systems that require specialty filters. Save yourself some of the HVAC company markup with Atomic Filters.

I can rarely find this filter size anymore even on Amazon so I was very happy to find it here and at a great price too. Allergies make the higher merv rating very welcome in this house. I will definitely return when it's time to replace this one.

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.
