A lot of wasted $$ as I bought 4 of the smelly things. Air is not fresh and clean.. it's a very bad odor. Not sure if it's the glue, or if the cardboard parts are recycled cardboard.. the smell is musty and very offensive. I emailed the company to let them know.
My bad, I didn't take the time to look at the actual dimensions of the filter before ordering, they are too small (by about half an inch) for a standard Honeywell enclosure. I reused the paper shell from the Honeywell filter and placed the Filterbuy model inside it. Also the pleats were glued somewhat haphazardly, not uniformly. Other than that, we'll see how they work from here on.
Had a hard time finding the ones to fit my furnace. Youd think if they label a filter 16x 20x4 thats what it would be, not 5/16 oversized. This was a great place to shop for filters.
I bought a 20x25x4 MERV 13 Pleated Air Filter. I noticed that it was probably a 1/2 in. smaller then the 20X25X4 so it moves a small amount when the unit comes on.
