Owner's manual

Q: Does Model:U-31003 require replaceable filters? I did not find the answer to this question in the specifications. The only information about filters was that it had a ceramic filter. Does it use tap water or distilled water?

A: No you don't need filters for this model. I like to use distilled water because tap water might have minerals in it and you can get buildup in your humidifier.

Q: Can u use essential oils in this humidifier

A: undefined

Q: I use my cool mist Vick’s thermistor every night I find the nights I don’t have time or forget to fill it up . I wake with a headache and my head fills dry . When I use the Vick’s pack I sleep well and wake up with loose snot and my sinuses feel so good

Cool mist vaporizer
Easy to fill and not too difficult to clean up. Although the company does not claim it is necessary to use distilled water, that is probably a good idea. It will be easier to keep free of calcium buildup. I chose the side and because the description stated it was adequate for a 500 square-foot room. So far it has worked very well. I empty and wash it out once a day

Does The Job
I wish I could give this more, but there are a few things that both my wife and myself do not like. We may be trivial, but a review is supposed to be an honest assessment of a product purchased. Good things first. It does not take up to much space. The cool-mist is cool, and the amount of mist can be increased or reduced. A fill up lasts up to three days if used over night like we do. Has a 2/8/12 hour timer that seems to work, but I usually set the thing at 12 hours when I start it and manually shut it off in the morning. Has a cylindrical movable directional diffuser that moves the mist any way you want it to go in 360 degrees. Things we do not like. Not the easiest to fill and the handle on the bottom to hold the 1.5 gallon container while works, just seems like it will not one day. Internally has a bright bluish LED light that seems overtly too bright. I use a very dark shirt to wrap around the unit to "calm" the light down. Seems to have a unique yet somewhat offensive odor (bothers my wife more than me) via the cool mist. The diffuser mentioned earlier comes off extremely easy and the cat has found it and knocks it off the unit to play on the floor with it. Thinking of taping it down. If you want a "night lite" in a cool mist unit, and/or not concerned with a few of the items mentioned above, most of the previous reviews were quite positive. I'm just trying to give it an honest, but maybe trivial assessment to help you make an informed decision about this unit that maybe other folks either did not care about or just ignored the things that bothers us. I hope after a while the odor goes away (I think it will). I would recommend this unit as good working humidifier.

Decent humdifier
I wanted an ultrasonic humidifier to eliminate the heating element, which usually makes a humidifier difficult to keep clean. This has stayed much cleaner. On one of the lower settings, it does last all day (or overnight). There are two things I am not thrilled about. 1) There is a light in the tank (I understand why it is there- it makes it easier to see the water level) that you cannot shut off. This makes it annoying to have in the bedroom while you are trying to sleep. 2) I did not pay the extra money for a warm mist humidifier. Next time I will. This has made the house noticeably cooler. Living through a Winter in the Northeast, this is not the best feature. It will be pleasant in the Summer, but humidifying is usually not as necessary in the warmer seasons.
