I bought these filters in the past and I think they are very well made. I don't know if they compare to the lennox brand but they seam to work just fine

Affordable Filters

I'm glad I found this website for affordable filters. The Merv 16 was getting very costly, and the Merv 13 seems as if will do the same job, if the not the same, I feel it will be close enough, especially for their price
