Good, high quality ac filters that arrive on time to be changed every 60-days. Ac serviced every six months. Always clean. Just keeps the drains clean and flowing and things stay good to go. I’ve been pleased.

These Filters MERV 13 20" X 20" X 1" are the best filters for fitment, size (custom), and material for filtration.
Will continue to purchase them!
The same to be said about the 10" x 10" x 1". .
