50%of the flutes were crunched up together reducing the surface area. This decrease the life of the filter. I tried to spread out the flutes but was not that successful do to the amount of glue used. Will look at other brands
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.
