Holmes 3 gal. Cool Mist Humidifier  Product Reviews

"After about a week of normal nighttime use, the filter needs changing! Ugh. It doesn't wick the water up anymore. I called Bionaire who said filters should last 4 weeks. They blamed hard water but we have Culligan soft water! So they sold me more filters and some water softener to use when I fill the basin to see if the filters will last longer. The filters also have a black layer that crumbles all over. Messy. I'm close to trashing it and buying another kind without a filter. My last Evenflo humidifier filter didn't behave this way; it stayed wet and continued working even with a 'full/dirty' filter so I'm not happy about the Bionaire stopping humidifying. Their processing takes 3 weeks for me to get the new filters and that's not acceptable. The unit is very quiet and you have to be careful when moving it otherwise it will spill but it's never 'leaked'."

"This is sleak, easy to use, has NEVER leaked, and is SUPER quiet. I just can't figure out which filter it uses. In retrospect I should have bought some at the same time..."

"I bought one of these and I will be returning it (or throwing the damn thing away, if a return isn't possible) and buying a different brand. The instruction manual tells you to place it on a "waterproof pad" and not to place it on carpets or rugs that may be damaged by water. I assumed this meant it might drip a little, which sounded reasonable enough. Wrong. It means the product gushes gallons of water out the bottom like a fountain. I ran it overnight in our bedroom, sitting in a roasting pan in case of drips. After a few hours the roasting pan had filled up completely and the base of the product was getting dangerously close to being immersed. I don't know where you're supposed to put this product so it would neither destroy your flooring or immerse itself in water and then blow out. Assuming I didn't get a defective one, it seems very poorly designed and I would not recommend it to anyone. Apart from the horrendous leakage, it runs quiet and produces a good amount of humidity."
