Lennox Healthy Climate X8788 MERV 16 Filter - 20 x 26 x 5 - Genuine Lennox Product

Filters even fine dust. Our ducts are hardly dirty even after 3 years

Received it on with problems.

Works great with our heating system.

actual measurements are 19 3/4 x 25 1/4 x 4 1/4. I had to buy another 1 inch filter to fill in the gap. Now the furnace squeels when the air is flowing. Next year I will not buy this one again, it is not the size advertized. Very dissapointed.

will be ordering again

These filters are well made and really do a great job of cleaning the air. I will use these exclusively.

Amazing how much these trap from our HVAC air... Sort of scary we breath all this dust otherwise. We run our 3500 sq ft home fan continuously (on low) and this filter lasts 6 months.

We replace our whole house filter once a year. It’s much less expensive to buy online than through out HVAC service company. We think it helps a lot with the asthma and allergies we have.

Perfect fit and definitely a fantastic price.

Guaranteed by HVAC installer would have to replace once each year. Must replace filter every 6 months!
