Optimus U-31001 1.5-Gallon Cool Mist Ultrasonic Humidifier

While this humidifier doesn't have all the bells and whistles, it works excellent and delivers the right amount of moisture into the air. What I also like about it is that there are no weekly filters to use(wick), plus the added expenses of purchasing wicks.

Its easy to use, it holds enough water that I only have to fill it every other night, and it works very well. The blue ring around the adjustment knob lights up bright blue but it can be turned off for those who do not like night lights. Operation is pretty quiet.

The drawbacks:

water flows out of the bottom of the reservoir into the base were the magic happens. This means that the base of the reservoir will be wet when you remove it to refill and things around the humidifier may get a little wet.

The part where the moisture comes from isn't secured to the top of the humidifier so when you remove the reservoir to refill and flip it upside down (you fill from the bottom), this part will probably fall off a few times before you remember to take it off and set it aside.

even considering those two things, its worth the money.

This is a super quiet machine and we've had no problems with it. If using the highest setting it'll typically run for 11-13 hours.

Not too big and not too small. It'll last about 2 -3 nights, ie does not require a refill every night (phew) and not too heavy to carry like bigger models (double phew). Plus, there's no nasty paper filter that gets instantly moldy.

I live in a dry climate and in the cold months with the heater running, we buy bedside humidifiers for the whole family to keep from drying out and catching colds. Of all the humidifiers we've tried, this one is far and away the best. It has a ceramic filter which does not need replacement but keeps the unit from getting as dirty as quickly as other humidifiers. The control knob gives you a lot of control, ranging from a barely noticeable stream of mist to a thick fog pouring out the top. It's very nearly silent, so light sleepers shouldn't worry. Other reasons I love it: large water tank so you won't run out over night, a directional spout at the top to point the mist where you want it and a little brush beneath the tank for cleaning. I can't think of anything I'd change about this unit. I'm surprised I've never heard of Optimus before.
