Customer Reviews:
Very helpful in cleaning air especially during recent wildfire smoke in the northeast
Collected by Trustpilot.comGood filter, reliable supplier
Collected by Trustpilot.comThe filters are good quality and about $20 less expensive than the filters brought by my furnace contractor. Since I have three dogs in my house, I need to change my filters more than once per year. When I originally received this year's automatic order, the filters were damaged in transit. Customer service had new filters sent out promptly -- they arrived undamaged. Thanks.

Collected by Trustpilot.comI should have read the description more carefully as this is NOT an OEM filter but is a cheaply made knock-off. I won’t make this mistake again. I can buy the actual Lennox filter at the same price and will do so from now on.
