Bests & Worsts Reviews from Amazon

This product is not as advertised. The product description says 19 1/2” tall and product specs say 19.9”. For those at Filtrete 19 1/2” is 19.5” not 19.9”. The product is slim and that is something I can live with however being so short to the point air and particles can (and will) just go over it is worthless. For others benefit this product is 19.5” tall. Also, “slim” is a modifier to describe thickness. Not overall dimensions, that would be “compact”. This is specifically for certain units that are not actually 20x25x4. Don’t bother with the descriptions for this product because they are contradictory.
