Lennox filters

Filters are good quality however they are slightly larger than listed on the packaging, making them an incredibly tight fit. I will likely get the branded filters next time to avoid this issue.

When new filters arrive, it reminds me to actually replace my air filters, otherwise I would forget. I just replaced them for the first time in six months and they were much filthier than I expected in such a short time. Now I'm on the 3-month train.

Appear excellent substitute for Honeywell.

These are replacements for the Honeywell MERV 13 filters we have been using. American made and appear excellent. I expect they will be fine, but we have just installed them. I'll know better in 3-4 months. Much less expensive.
