It's hard to know how good a filter is just by looking at it. These look pretty basic and pretty much like the filters I had been getting from my local furnace guy. Those were only supposed to last a month, and you are saying these can last 3 months. I wondering if I should have purchased one of your higher end filters. I do have a basement workshop. the filters are used in geothermal system with a water furnace. Any recommendations would be useful.
It is very hard to find a 14x14x1 air filter that actually fits my 13x13x3/4 ceiling vent. Thank you, thank you, thank you!!! I will always buy from you.
I have a Payne furnace which requires an unusual filter size (i.e. 16 1/4 X 21 1/2 X 1). This size is not readily available at your local home improvement store. In searching the internet I found your company with a tremendous size selection of filters. Unfortunately my first purchase was the wrong size, (i.e. 16 X 20 X 1). These did not fit at all and ended up on the bottom of the furnace. I re-ordered the 16 X 21 !/2 X 1 size and they seem to be working well, so I am extremely satisfied. Thank you. I still have four (4) of the originally purchased filters left over which I cannot use. Can I return them for a refund or credit towards my next purchase. Thanks.
