Quiet, clean, long lasting, no messy filter, more than adequately humidifies our rooms. We bought one for large living area and one for large bedroom. Our skin is less dry, respiratory dryness solved, house feels warmer. Love it!!

Very good humidifier - 01/18/2019
Reviewer: John sensback
It took a while to receive because it was out of stock at the time. Not an issue really. The estimates for delivery were very good. The product was packaged well, no damage, etc. Very easy to set up and operate. The product is fairly large, but not so much to be an eyesore. We placed it in the bedroom to add some moisture while we sleep. Has certainly made a difference in our morning sinuses. The winters here are fairly dry and it really helps the air quality. We do plan on getting a second one for the main living area. On the lowest setting it uses the entire water storage container in just under 24 hours so you need to check the water container often on higher settings.

Purchased this unit in January 2019 for the dry Minnesota winters. My new wife is from Hawaii and the dryness destroys her skin. This unit has fixed the problem for her very well. Highly recommend this unit

Humidifier Review - 12/16/2018
Reviewer: Aila Bolton
The humidifier seems to be working properly, but it failed to turn on after I had turned it off for a day. When I tried later it did turn on. I am concerned that this may happen again and that it will never turn on again.

I have used this unit for three weeks. It is extremely quiet and works well. No white mist. Easy to clean.

Q: I hear the fan turning, but I don't see any mist. Is my humidifier operating properly?
A: Dry air is pulled through the system and a fan disperses invisible, moisture balanced air. There is no "mist" emitted. When operating normally, you will feel only cool air coming from the unit. Monitor the water level in your Tank/Base. If you notice a decrease in the Water Tank over 24 hours then the unit is operating normally.
Q: My unit has been running for several hours. I hear the fan spinning, but I do not notice the water level in the tank decreasing.
A: First, check the filter to ensure it is wet. If the pad appears dry, remove it from the Base and gently
rinse under cool water. Reposition wet filter in the Base. You may also want to note the current
moisture level in your home. If the humidity level is over 60% the unit will not put out much moisture
as your air is already saturated. Also verify the upper enclosure and water tank are properly seated.
Q: My filter has turned light brown and rust colored. Do I need a new filter?
A: Probably not. Since your filter has been made with Protec antimicrobial, the change in color
indicates only a mineral deposit. Soak filter in a sink full of cool water to help break up deposits. The discoloration may remain but will not affect the humidifier's performance.
Q: My humidifier doesn't appear to be as clean as when I first purchased and/or I'm smelling an unpleasant odor. What should I do?
A: You probably need to replace your Protec Antimicrobial Cartridge. This cartridge helps your
humidifier stay cleaner, longer and helps freshen the mist. If you have been using your humidifier
regularly for over 30 days replace the Protec cartridge and follow the cleaning instructions.
