Great Prices

This is our new system filter. Have ordered other filters from this co. in the past, and this filter was selling for anything from 250 to 150 in other places. The company that maintains my system wanted 150 for just the filter, then 50 to replace it, so I

New carbon coating

This new carbon coating restricts the air flow. My furnace now whines, which it does when the air flow is reduced. Next time I hope to find the plain version.

Price and Performance

Looking around it was Discount Furnance Filters who provided me what I was looking for. Hard to find Merv 16 filter at the best price. They perform as expected and get me back to using the manufacturer installed original filter. Thanks DF!

Great product and service!

When we got our new furnace, our local installer encouraged us to buy replacement filters from him. Always out for a better deal, I researched online availability and prices of alternatives, and came to Reading the reviews convi

Great Service, Great Price

Filters are same as provided by our commercial HVAC company. Arrive within 1-3 days, even can set up automatic reminder. We're an animal hospital so I need to replace filters every 3 months. Looks like the system sucked up a whole cat every time. The pric

X6675 furnace filter

Previously, I used 1" filters in an old furnace, which did not filter enough to reduce my wife's allergy symptoms, and left my duct work filthy. Since having installed new ducts and a new Lennox furnace, which uses this 5" Merv 16 filter, my wife's aller

Price & quality can't be beat

I installed a new Lennox heat pump / air conditioning unit a couple years ago. The first time I had to replace the Merv 16 filter, I was in shock! The installation company charged $190.00 for the filter. I purchased through them for a couple times unti
