    I've tried many different kinds of humidifiers, over the years, and this one is by far the best of all. Other models sent too much humidity into the air, made the room feel colder, and left left a mild musty smell. This unit keeps the air pleasant, both by maintaining an appropriate balance of humidity and by cleaning the air, with the ion filtration system. it is also has a sleek design, and runs quietly, which means it's fine to locate it in the bedroom. I've already recommended it to friends, and am seriously considering purchasing a second unit, for my study.

    I waited before writing this review to see if the product was good as the others reviews stated. And yes it is. Is so easy to maintain, not like others humidifier I had before, you won’t see any mold growing in the water thank. Another plus is, even though you don’t see the steam coming out the equipment, you will feel the air in the room getting fresher and cooler. The best part for me is after more than a month of daily usage the room doesn’t smell moldy like the one I had before. The front panel shows the quality of the air, I can’t tell is true but is good to see the change of light (green/yellow/red) and the number showing how humid is the air . The access to the filters is also very easy. I am happy with this purchase.

    Runs quietly. Cleans the air and keeps it fresh. Easy to control with push buttons. The colored light fluctuates with more or less pollutants in the air. The light brightness is able to be changed from brigh to off making it perfect to sleep while running in a dark room. A red light flashes when the water tank needs refilling which is usually every 10-12 hours in my home.

    very effective air cleaner/humidifier combo

    These are great, very effective air cleaner/humidifier units. The reservoir is a little small, I have to refill most nights, which is a chore with three of them in our house. The unit also lacks the ability to set a desired humidity. It's either on high, med, or low, or off. It can't reach 55% humidity and turn off. I'd think for this price it should have that. They run very quietly. The filters vacuum clean very easily, and only need to be changed every few years. All in all they're good, and priced well.

    Excellent air purifier and humidifier that only needs to be occasionally cleaned and dusted. It does a great job of keeping our bedroom cleaner especially with a pet. 5 years use for the filters is fantastic too, worth the investment.

    Love it. The amount of dust on the furniture has been drastically reduced. We also love the humidifier. It increases humidity without leaving a film on furniture.

    Not a bad product - does what it suppose to do. It's quiet - lowers humidity ad cleans some air. A bit expensive for what it does.

    Since purchasing this unit a month ago, we've been extremely satisfied. The air feels fresh and the built-in humidifier is a great benefit in the winter. It has a nice, clean look and feels solidly made. We're considering buying additional units for the rest of our home.

    I want one of these in every room. Quiet cleaning of the air while humidification at an automatic set point makes this unit superior over the others I own. High quality is what I wanted and this unit is just that.

    Works great, like the look of it as well. I think our room was slightly too large for the humidifier function though. Replacement filters are expensive.

    it's on the expensive side, but good machine

    this is my third air purifier/humidifier. the first time i bought a cheap brand for about 130 and the dust meter is all over the place. it just didn't impress me all that much so i had to return it. it wasn't too quiet, and has only the purifying function. I bought another one for the contemporary look for the house. that one was not cheap either and doenst have purifying function. I came across this sharp one and decided to give it a shot. what attracted me was that its' purifying and humidifying in one. when i got the unit, it's on the larger side. the look is pretty clean and sleek though. i use it for my bedroom which is not too big, so the machine can cover the area without a problem. it's relatively quiet, but occasionally you would hear the water bubbling. the display light can be turned on or off so that it doenst bother you at night time sleeping. i don't have allergy problems, so i can't tell how much air the unit actually purifies. I was hoping to live in a healthier environment, my house gets dusty very easily and i don't want to breath in all the dust particles. the only concern i have is the filter. i haven't figured out how often i need to change it or how much it cost. it doesn't seem like a cheap filter to replace. hopefully not too often. i would recommend this for those who want to have cleaner air

    I initially bought this machine when we found mold in our room. It worked so well that we now use it every day even after resolving the mold issue. It creates a white noise that blocks out all other noises, allowing us to sleep better at night while keeping the air clean!

    This humidifier/ air purifier works great! My kids sleep better. It was easy to setup and use. The directions even encourage the use of tap water! If you run out of water the machine turns off automatically! It was well worth the money and I would definitely recommend it.

    This units works well. Quiet running and seems to do a great job as my allergies are less since having this unit. As other reviews noted, the light on the unit can be a distraction but can be blocked with tape if desired.
