No merv 8 or 9 available in custom size so I purchased the merv 11. Haven't installed one yet. Hope it's not too much for my small house.

I have had trouble with local stores selling filter of this size yet will not fit - missing the size by a 1/4 of an inch. This one fit. We could tell the air quality difference immediately!!

I have been buying these filters for the past 3 years. I modified the filter housing to accept these filters and they work great. I like the fact they can be made to the size needed.

This was my second time ordering online. We have a big house with 5 filters all different sizes. The fit is perfect and the quality great. I especially like being able to purchase filters that have a higher MERV as this house is older and drafty, and we are pet parents. I do notice a difference in the air quality.
