In my opinion the Filterbuy branded Merv 13 pleated air filters work just as good as the name brand at a good price. I recently had a soot accident if you will from my gas furnace recently and panicked. I purchased a set of these filters to swap out first in 2 weeks then after a month then after 2 months. These filters are good for 3 months but I wanted to get rid of lingering soot in the air as quickly as possible. These have done a very good job and will continue to purchase them!
Fit is good and the product functions well. The company should improve packaging. The box was taped together and didn't look professional. I would still re-order from this company.
