I bought this product because of the price for what seemed like an equivalent product to the Honeywell or AAF (American Air Filter) product. But it a poor cousin. It is cheaper, but what you get is less as well. Note the key differences compared to the AAF product:

1 - It is thinner: 3-5/8 inches versus 4-3/8 inches.
2 - It has only 13 folds of the filter versus 18.

It all adds up to less filtration surface. Pay less, get less. I'll buy the AAF or Honeywell next time.

The filter is not the size as the Honeywell filter. I ordered a 20X25X4 filter but I got a 19 1/2 X 24 1/2 X 3 5/8 filter.

This review is from: 20 x 25 x 4 Merv 12 (Case of 6) Furnace Air Filters

Furnace filters are outrageously priced. I was happy to find a place where I could get 4 inch or better filters for a more reasonable price (Its still about $1.50 to make I bet.). Shipping was good from these guys and I got a good supply to last me a while. Having used 4 inch filters for a while I think the quality on these is as good as anything else I've seen. Not sure if the MERV 12 rating really makes a difference (I had MERV 8 before and I haven't notice a difference in the allergen level.).
