Rated 5 out of 5 by MUCH better than the plain white Whisper cartridge Excelente filter cartridges! MUCH better than the plain white Whisper cartridges !! They have a white side that is a coarse "pre-filter" with the other side is a blue "tight/dense" filter. THEY WORK GREAT (and with them already assembled.... no stress) 04/11/2012
