I have used these Lennox filters in my Lennox furnace for 3 years. They are sturdy and dimensions match furnace filter box for a tight fit. Heating/AC personnel recommend higher MERV filters but I have not heard a good reason.

Exactly what I ordered except apparently they over shipped because I received 4 filters instead of 3! Product quality is as advertised and I’m very happy with the product.

I used it as a replacement for a flex one, X8309. Model HCXF16-11. FIts perfectly.

Best HVAC filters I’ve ever used. I keep a year’s worth on hand bc I can’t find these in my local stores. Keeps my system humming nicely. Worth every penny!

This is the best fit for our LENNOX furnace — have tried other cheaper imitations, but they are so much smaller so that the furnace doesn’t work properly — get the name brand!!!!
