Question: My humidifier is starting to make the room smell really bad, and it's only been 3 weeks! Do I need a replacement filter or is it our tap water?
Document: We have had this humidifier for 4 months now and I am really disappointed. The filters constantly need to be changed (every two to three weeks) and they aren't cheap, but if you don't change them the room starts to smell musty. We cleaned ours daily and changed the water, it didn't help. The only good thing about this humidifier is the stars and the ability to use the vapo pads. Sad we wasted our money.
We bought this for our son last spring to replace a warm mist humidifier that was always getting moldy. The one nice thing about the warm mist was that it didn't need filters, but this one does. We used this for about 2-3 months in the spring and then put it away until a month ago. We are on our 4th filter/wick.This does a good job of keeping the room air slightly moist. It also makes the room a bit cool.
Be aware that this humidifier needs replacement more frequently than the instructions let on. Our filters began to discolor and smell funky after only a month. Our water is not overly hard either.
I bought this humidifier for my son's room. I followed the setup instructions, and after letting it run for 24 hours there was no noticeable difference in the room. I checked the water tank, and it looked like the water level had not gone down at all. After some investigating, I found that the plastic nub that is supposed to hold the water tank open was too short to do the job. I placed a dime on top of the nub, and that was enough to make it work.
I've bought probably eight to 10 humidifiers over the years. This one is average. I like the size. However, even with the adjustable knobs this model doesn't really put out enough humidity. It will definitely not harm your wood furniture as there is so little water being put out into the air. I also don't care for all the water that collects in the base because the filter sits in the base as well and soaks up this extra water.
The filter is a real pain in the neck. I wish I'd known it had afilter because I would have ordered a humidifier without one.And there are plenty of options. The booklet says the filtershould last one month. The filter lasted about 3 days tops.And then you have to order a filter and wait for it to arrive.
I was impressed with how quiet the machine is when it's running. The next morning Damien woke up and he was still a little sick but he looked like he had a better nights sleep and he didn't sound nearly as congested. The humidifier was used again the next night and after that, Damien was good as new. The really cool thing is that you don't have to have the humidifier running to use the starry effect, so he can enjoy that even when he's feeling great. This would make a perfect gift!
I previously owned a Vicks cool mist humidifier,Vicks 1.0 Gallon Cool Mist Humidifier. I bought the other one about two years ago and loved it but it had a lot of wear. I put this humidifier on a wish list and it was purchased for me. The thing that is great, it takes the same filters as my other humidifier which I still had left over, Protec WF2 Extended Life Replacement Humidifier Filter.My older humidifier was very loud.
I've had this about 3 weeks and it has been used steadily, first to moisturize then to help with a stuffy nose while using the VapoPads. One complementary scent pad is included with your unit.
I found out some things after having bought this humidifier that, had I known before purchasing, I would have kept looking for a decent cool mist vaporizer.1. Seriously. WAY too loud. On high, it's like a jackhammer and it shakes the whole room.2. You have to buy filters for it.3. Probably the most important issue I take with it is that if the moisture content in the air is 60%, the vaporizer simply won't put out moisture.
Answer: Honestly my tap water is HORRIBLE and I didn't change my filter for 2 months. I never had problems with smell or the quality. Do you have pets or anything else that might be causing it?
