Love the way they have pretty much any size you need, quality is great. I receive my filters within a couple of days, if you have a problem or mix up they were gracious and do whatever it took to make it right! Great filters at a good price!

I realized I had used my last filter and the one in my furnace was old, so I ordered a new 6 pack immediately. The new box was on my porch the next day! Super easy website and fantastic quality and price. Keep it up!

Would be nice if u can add the weather strips around the filter to better prevent air leak thru.

Not satisfied!

These filters do not fit! They are the wrong size! They are 1/2" too short all around and do not filter anything! They just rattle around and let the dust and dog hair pass right through! They are 15 1/2" by 19 1/2" by 3 1/2". The quality is poor and they are not anything like the the filters I bought before.

I didn’t think the actual size would be an issue but it was especially the width
