Lennox X6666 17x26x4 (16-5/8x26) OEM MERV 16 Replacement Furnace Filter- 1 pack

A perfect fit!!!

The highest efficiency on the market filter (MERV16) will be protecting me & my family (let alone the equipment) for the next 12 months.
Get yourself one & have your ECM blower ready!

Atomic's filter buying experience is awesome! No issues with this filter. We have been using this filter for years with no issues!

I received excellent service and a good price for filter I purchased. I would recommend this company

Short and sweet:
Great price! Fast delivery! Official parts!
Second time ordering from Atomic Filters I'm sure it's not the last.
