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.

I have used them in the past and went to a cheaper brand for a short period. I have now returned and am pleased with the higher quality these filters have.

Lasts longer

lasts longer than other filters. bought them specifically for dirt and sand as we live in the AZ desert and we get hit every year with sandstorms from the Cali sand dunes. Helps the pets with the seasonal allergies too. Grateful I do not have to climb the ladder a 12 times (x3) a year to change 3 filters out. Bought them for our shop too in 20x20s. Have to change 2 of them out there. I bought them for shop exhaust fumes and again dirt and sand.

These filters last longer than regular filters. I specifically bought them as we live in the desert and during monsoon season we get hit with sand from the Cali sand dunes. Helps the pets with their seasonal allergies too.
