Easy to order, great product and best price.

I have been ordering these replacement filters from DiscountFilters for a number of years now. They always arrive on time, are reasonably priced and fit perfectly. I replace them every 2-3 months, no matter the time of the year, since I run the fan constantly. Thank you.
