These exact fit high capacity furnace filters are ideal for multiple seasonal use. Used during the winter months in Wisconsin they offer exceptional filtering of fresh air to the high efficiency gas furnace and during the summer months when running the cooling cycle they are very good at screening out the dust and dander from the two red golden retrievers that grace our home. MERV 13 offers the highest capacity in the pleated filter design without a reduction in air flow or efficiency I can highly recommend these exact fit filters used by Trane high efficiency furnaces and cooling hvac systems
I was disappointed with this purchase. The filter cardboard frames are very thin, and they are supposed to be the same size as we have always used, however they are enough too large that they do not slide in the frame easy. We had to practically jam them in the frame.
