14x20x4 MERV 11 Pleated Air Filter

We’ve used these filters for the past 2 years. They really do the job well. And, the shipping service is supreme!

Great quality, timely delivery.

looks good

They seem to fit a little tighter than my previous filters, but that turns out to be my benefit; in the unorthodox way I'm using them. Using a thicker filter allows me to step-up the MERV rating without taxing the air-handler, so I was quite pleased that they would hold themselves in place without any modification to the filter holder that was meant to hold a 1" thick filter.

Great product. Bought 2 for what I would spent locally. Easy ordering and prompt service.
