My trusty filter
on March 18, 2023

I have been using this particular brand and type of furnace filter for decades! It seems to do a fabulous job of catching the gunk out of the air that comes through the furnace system. Two thumbs up from me!

Prepare to be Amazed!

I purchased this filter a few days ago. Before installing this filter, my husband was sneezing very often everyday. We were so amazed the first day, he did not sneeze at all; everyday since, it has been the same. I know a person would have a hard time believing it could work so well and so fast, but it is absolutely true. Thank you for making such a wonderfully made product.

Too restrictive.
on September 29, 2025
Posted by: Herman the German
Too restrictive does not allow enough air flow. My 5 ton unit is sized correctly for my home. My return is 1024 sq in Unit struggled to cool with these in higher temperatures. Unit is less then a year old as soon as we put a less restrictive filter in the air flow was better and unit was quieter.
