20" box fan filter

Just the right size for a 20" box fan. 4" width creates minimal air resistance.

First purchase so we'll see how it goes. Seems to be of good quality and purchasing experience was easy and quick.

First time user. Sadly very very poor quality, flimsy too. But I guess u get what u pay for. Shame on me. And size is slightly smaller (depth) than it should be.

furnace / heat pump filters
on August 28, 2019

Excellent quality, and glad to find the 16x24 size furnace filter which my local stores seldom had. The 4" wide heat pump filter is working fine also, though it is not really a full 4" wide and is narrower than the 3M Filtrete brand I used before, which hopefully is not a problem.

Filters for my Furnace
on August 19, 2019

I just recently bought my second set of filters (4) for this new year. I was able to just go online, order them and within a few days, they had them on the way to me.Couldn't have been easier and I saved a fair amount of money by getting them from FilterBuy, instead of the local HVAC company that charges about twice as much.So, I'm happy, FB is happy, UPS is happy....everyone is happy. I'll be getting my third set from them when the time comes.If you're just thinking about it, then stop doing that and get to the ordering page. You'll be glad you did.BR in Spokane

Great filter, but....

As a retired Building Engineer I know my filters. This is truly a professional grade filter. The reason for only four stars is that it is a bit smaller the the original filter it was replacing. It will work, but its flopping in its mounting when the fan engages.
