great fit and perfect size! make sure to measure and see what will fit your filter opening. service was prompt and successful. will be ordering more next year!
To see upgraded allergy filters for an hvac is awesome. To have the almost perfect size makes it even better. Yes my system makes a tight squeeze but at least we have the top of the line to catch almost all allergens in the air.
The Fit of my filter was perfect . I had no trouble changing it . I feel like this filter does as good as the job in cleaning my air as the higher priced ones.18 x 20 x 1 is'nt the easiest to find lately . Had no trouble finding the right fit and size .
I bought the Mer 13 filters after we were badly affected by the recent fires in Orange County. Happy with the filters so far! Although, one was a bit too snug so it took quite a bit of maneuvering..
