pore construction and reduced size.

the filters elements inside the frame are loose and dont cover the space properly. and the frame is 1/4" smaller all around. the filter fits too loose and allows air to go around it. Bad way to save money.

Great filters

Found exactly what I needed for my furnace. Can't find these in a regular home improvement store. Just bought my home and needed new filters and this was in it and I got the information off the old filter and looked this site up and found my replacement very easily. Recommend this site and very fast shipping also.

Very disappointed

Your filters were substantially inferior to the filters that I had previously used. I am so disappointed and will never buy them again. I wish I had not purchased in bulk. 😢
