Filterbuy 20x20x5 Lennox Compatible MERV 8 Air Filter

Perfect fit and arrived for installation within 2 days after ordering.

This portion of my order was correct.

Easy to purchase and shipped fast. Very pleased. THX!

It is always strange to review products right after you buy them--it is too soon to know. All I can really say is that this company shipped relatively quickly and the filters arrived in good condition and fit properly. I tried another company but they shipped the wrong filter type and also for some reason the filters arrived damaged-twice. I finally gave up on that company, except for another filter where the exact size is critical. Filterbuy once shipped filters that did not fit, due to some confusion on the size on their website. It is really critical that you measure the old filter and have the replacement filter company swear on a stack of Bibles that their replacement is the exact same size (or maybe slightly smaller). If the replacement is only a tiny bit bigger you won't be able to cram it in.Except that the thickness is usually quite a bit less than the nominal size and that is OK. In the case of this so-called 20 x 20 x 5 (inches) filter, the thickness is actually 4-3/8 inches, which is what it is supposed to be. Super confusing.

They work great and easy to order
