Review on Filterbuy 14x25x1 HVAC AC Furnace Air Filters, MERV 8, Pleated (4-Pack, Silver) by Devin Lee

I have used all filter levels before. Quality filters are expensive. HVAC specialists say they can be so dense that they make your HVAC's work harder. The cheapest seem acceptable at first glance when changed monthly, but they let dust through - as you can see if they come out pretty clean when you take them off. HVAC experts recommend an average MERV rating, but make sure it has wrinkles and change it monthly. Thus, it is an ideal product at a reasonable price for a monthly replacement.
