Overhead ducts stay relatively clean now that we are using Merv11 filters. The automatic shipments work well, no 2nd guessing or forgetting to order them.

New user here. Have been a Filtrete user for years. Seemingly good quality, too soon to tell. Super fast service and good prices vs the brand names.

Good looking filters, put one in. Unfortunately, my filter box had been crushed. Needless to say, the filters were a little flat.
