Good Product, excellent shipping service, they are a tad bit tight in the height, my unit being a Goodman but using a Lennox sized filter was a bit of a knuckldrill finding the correct filter, but they work.

The 20x25x5 AIRx ALLERGY Replacement Air Filter - MERV 11 does a good job. Although it’s a bit on the pricey side, it is a good filter and lasts six months.

John 2 days ago

The filters are good quality. The only gripe I had there was a hole on each side of the shipping box. I didn’t consider that was their fault. I carefully removed each filter from the box and the filters were still usable.

Too bad furnace manufactures don't standardize size of Hight and width and length for these type s filters within the industry, price would drop for sure. Probably get a higher merv rated filter then in competition between manufactures.

MICHAEL K FREEMAN 17 days ago

The product arrived quickly and undamaged. The visual quality of the product is not quite the same as the OEM filter, however, I will withhold final judgement until I see how it performs.

I thought I was buying what I had in the past, original equipment. This is a generic filter. I would have preferred the original I had purchased in the past. No indication you were shipping something else.

Not all filters are the same! I bought this one after the one I bought from a name brand store did not fit! I change this filter every six months and it works well.

Robert Spoonemore 14 days ago

Great value and works well with one minor drawback and that is the cross-hatched pieces catch easily when pulled out to inspect the filter. I can live with that.

Irvn 22 days ago

Arrived with no damage and a perfect fit. This is my second order of these filters and will continue to use these.

David Terre 11 days ago

The filters I got were damaged in the shipping process and most were unusable. This happened twice for the same order. This company was good at replacing damaged goods the first try. After shipping a second time, the filters were damaged again and I just gave up. They need to find sturdy boxes or change shipping companies.

Dale Biesenthal 22 days ago

I have already been asked to review my order of filters and did so. I am very happy with the quality and price of the filters. Its the way they are shipped that doesn't make since to me. They are sent from the factory in Indianapolis Indiana to Champaign Illinois(pass Springfield Illinois) to St. Louis Missouri then back to Springfield Illinois and last to New Berlin Illinois which is about 10 miles west of Springfield Illinois. I will still order more when I need them.

I ordered the wrong size 24x20x4 instead of 25x20x4. When I called to reorder I was told the correct size would be sent at no cost to me, frt free and I could give the wrong ones away.
