The order I got from you is Merv 13 and they are good. But there is a few other companies that the armor of 13 how about the same. So I just wanted to let you know that its price I am looking for because times are tough today. But I wouldnt hesitate buying from you again if the price is right thank you
I make a house filter out of four of the 4inch merv 13 filters and a box fan. ( see -ask this old house ). I make a new filter every 6 months. The first picture is a new filter, in the second picture is my house filter after six months, the third picture is a new filter compared to a used filter. Thank you Ask This Old House for the instructions and sharing the ideas. Thank you FilterBuy for making such good affordable filters that we can do this with.
Too thin - so that when the fan comes on I hear the filter smack as it's sucked against the frame.It is the size listed for the AC unit I have but is a half inch too thin - the Honeywell one fit properly.Is it a cost-saving effect?
I was a little surprised that they came down sized. It still worked, but the folds in the filter were not neatly separated and some were clumped together. The filters were cheaper than 3M so it works for now. I purchased a 4-pack so a year from now I'll probably go back to the 3M product thar were perfect.
