Lennox Merv 11 filter
on July 15, 2025
Posted by: Anonymous
I purchased the Filterbuy 20x25x5 Merv 11 filter for my Lennox furnace. The quality appears comparable to the filter supplied by Lennox when the furnace was installed last year at a significantly lower price. To date I see no issues with the unit.

Lower quality than in the past. The cardboard frame was so flimsy that it barely held together for me to install it.

Had a hard time finding the right size for my indoor unitbut the ones I buy from filter buy are a perfect fit. The sizes are deceiving but they worked with me and we got it right.
