Excellent filters, fast delivery, priced right!
These filters are the exact ones used by the HVAC company in my system. I tried another more generic filter but the size was off. These fit perfectly, better price than I can get locally, and delivery was very fast. Plan to buy all my filters from Field Controls from now on!
