We notice the difference in our inside air quality immediately. Much less sneezing and nasal irritation. Looking into air duct cleaning as it has been some time since it was done.

20x20x1 filters are actually 19.5x19.5x1.

20x20x1 filters are actually 19.5x19.5x1. The opening for the filters is 20x20x1, hence there is not a tight fit.
