    • dry air
      Verified Purchase

      While I though I had a small albeit open main level I was hoping this unit would help with the dry air in the winter. I'm not sure if it just wasn't large enough to add enough moisture to the air or if I just waited too long and it couldn't adequately catch up. I was also leery of keeping it on when I was not home as I do not believe it has an auto shut off feature but would just keep running wasting electricity and drying out the filter. Which would require me to go through a lot of filters. I'll probably move this up to my bedroom and find something a little bigger for downstairs.

      i appreciate the closed sysytem, I have had others that collected dust near the intake. I alos appreciate the ease with which I can fill it and the silent operation. Humid air is great for your skin and nasal passages.

      We have a wood stove and this humidifier took care of the dryness in our living room. We have owned 2 other types that did not do the job, this one works great, thank you.

    • a decent small humidifier
      Verified Purchase

      This is a standard humidifier with a filter. It works well. It is a little loud on high, and seems best in a small room on medium. If you have a large area, look for a larger one. A typical bedroom is fine.

    • best so far for large room
      Verified Purchase

      By far the best humidifier I've used so far. This is not the ultrasonic ones (which I also have) and incudes an ultraviolet light to kill any germs in the water. You can use regular tap water and nothing gets wet or moist. You do not see any vapor it's just cool clean air. Goes through a gallon a day on the lowest setting.

    • Not that impressed
      Verified Purchase

      From the online reviews I read I had high hopes for this humidifier, but so far, it's just average. I've had it less than a week, but the tank is much smaller than I thought and so needs to be filled at least once a day on the lowest setting, and much more often if it's running on the higher setting. But the loud noise it makes on the highest setting means I won't run it on high often. And while the instructions tell you to not aim the mist at walls, furniture, curtains, you can't adjust the flow so the entire unit may have to be moved or turned. I have a smaller Homedics humidifier that I purchased last year and am using in another room, and I like it much more than this one - you can adjust the flow, the tank holds much more water, and it takes up much less space (and it cost less).
