Product review (1 stars): Not as good as Broan 41F from Homedepot
This filter is labeled as Broan 41F. The same filter (Broan 41F) at Homedepot has denser front side and the back side of filter is very much denser. This can't possibly do the same filtering. You can actually see through this filter but not a Broan 41F from Homedepot. Wish I had not bought these.
