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.
