AAF Flanders 20" x 25" x 1" Nested Glass MERV 1 Air Filter (4 Filters)

For the price, these work fine. I change them at least every 30 days. As long as you change them regularly, they allow good flow. They catch the dust. The size fits perfect (14x20x1).

I ordered four packages of four of the Flanders green 20 x 16 filter packs for the furnace and you only sent me one. Sorry but I'm gonna have to order more but that's OK overall you got them here in a hurry which is a great deal thank you, Janice.

Works well. Have been using these for about 20 years. Helps with allergies and dust and the size fits perfect in my vents. Also allows the perfect air flow.

I like it because it's the better filter for my home's machine performance. I don't like noticing it's rising in price. Last time I purchased this pack, it was $5.

I was told by my A/C guy that these filters were the best for my system. He said not to get the Pleated kind. So, about 2 years ago I found these at Walmart and ordered enough for 2 years. 2 years ran out yesterday so I needed more.
