AAF Flanders 12" x 12" x 1" Nested Glass MERV 1 Air Filter (4 Filters)

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.

Great, efficiency filter. I change every 30 - 40 days. May need to change every 25 days with pets in the place. Ease of installation with perfect size ordered each time. Started buying these 7 years ago. Great price though it's double since I started buying them but still better than others I've tried.

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.
