Keep up
on August 4, 2026
Posted by: Customer
One of the best things ive done is kept up with filters on my unit and returns. Some say it can be to restrictive and over work your unit, but our experience is the Merv 8 does well. I love choosing my exact size rather than standardizing.

Inexpensive and removes the dirt from system. In the summer, I change them monthly.

The width of my requested
on August 2, 2026
Posted by: Customer
The width of my requested filter was 16 3/8. Instead, you sent a 16 1/2" width. That additional 1/8 " was significant enough that it made the filter installation very difficult. I even sustained some damage to the filter trying to force it into the slot. The air condioning manufacture assigned this very precise measurement for a reason.
I have tried to use FilterBuy to save money. It appears that I will have to return to the premium price filter to eliminate the problem with fit.
