Great filter


Although it was a bit small for the opening, I popped the filter into the cardboard holder of the old disposable filter and it was a perfect fit!

BOTTOM LINE: Yes, I recommend this product

Very loose fit. I had to go to lowes and buy rubber door seals that have adhesive tape. I stuck the seals around the perimeter of the hole the filter goes into now the filter fits. Without the door seals their were huge gaps where the air would just go around the filter. Plan on spending 10 extra bucks to get a good seal. If it came with seal material 5 stars

BOTTOM LINE: Yes, I recommend this product
