Product review (5 stars): I LOVE THIS HUMIDIFIER!
FILTER LASTS FOR ABOUT 3 WEEKS- REALLY EASY TO SWAP OUT. I LOVE THIS HUMIDIFIER- HAVE BEEN USING DAILY FOR ABOUT A YEAR IN MY SON'S ROOM. IT HAS A VERY QUIET SETTING AND ONLY NEEDS TO BE FILLED ONCE EVERY 24 HOURS WITH WATER. SET IT AT A CERTAIN HUMIDITY AND FORGET ABOUT IT!
