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.

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.

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.

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.

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.

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. Thats over the top customer service.Kudos. All my neighbors will hear about this and get your company name. Bruce Walker

I checked, to see if they would fit, right after I received them, and all is fine. I had ordered from another outfit and they were too big. Ordered the correct size, but they would not fit, so I had to send them back. Hope I get my refund, ha So thank you, these are fine!
