I bought the #360 in Oct. 2005, and after about 4 weeks of operation the motor started to make a really bad rattling sound, Oh crap where is the receipt????? Can't find it!!!! Well, knowing that most stores won't return anything without a receipt if it's been used, I figured I would have to take advantage of the 5 year warrenty and contact the mfg. for a replacement. In the meantime I can't be without a humidifier so I went out and bought another one, same Mfg. (Honeywell)but a differant model to be on the safe side thinking if I go differant I shouldn't have any trouble......THINK AGAIN!!!!
I bought the HCM-645 on 11-15-05 and on this day 11-29-05, yes thats right 13 days later.....This motor has started to rattle, not quite as loud as the other but that won't last long.
I called the Mfg. about the one I had no receipt for and they wanted to charge me $10.00 for warrenty processing and I was to pay shipping cost both ways, estimated shipping cost would be $20.00 so for $30.00 they would send me a new humidifer. I paid $32.99 orginally does this make sense????. Well, I took the information on returning only to hang up the phone and call Wal-Mart just to see if they would take it back. Guess what? They had no problem in returning it for store credit and also took back the extra filters I purhased.
So my thought on Honeywell Humidifers, BUYER BEWARE, something is definatly wrong with the components in the motor operation in 2004 and 2005 models
The second, and deal breaker problem, is overly apparent when refilling the tanks. The tanks are made of a clear, very fragile plastic that, if touched on the side while full, crack. The first crack on one unit appeared from some unknown bump and was found hours later with a pool of water around it. Now we do not have children, and our dog is about as mellow as dogs come, so we aren't sure how it appeared. So, ok, on crack -- we superglued the crack to reinforce it, it held, and we were generally pleased. Then another, on another machine, on a different floor, appeared. Hmmm, more superglue. From there we know what happened. When we attempted to refill the original tank (first superglue job) about a week later, after it had held through a number of refillings, the bottom was bumped against the sink when full. This caused the superglued crack to spread very quickly and a chunk of the sidewall broke loose.Read more ›
The filter situation has been covered to death in the comments. To be clear, yes it can be difficult to find the exact model of filter for this unit. That doesn't mean you can't find filters though. It's extremely easy to cut down a filter that's a little too large for this humidifier. Grab your scissors and spend the 10 seconds it takes to cut a cheap filter from Wal-Mart down. It's a painless activity.
