buy this one!

I have purchased many humidifiers; this one is by far the best. I like that I can control everything from my cellphone, and I am fairly certain that I will buy another one.

Whisper Quiet...

I had another brand of humidifier that was filled from the bottom of the tank. I replaced it with this one. This dehumidifier is so quiet and easy to fill. It is small but suits my needs. It adds moisture to the air and includes a light that can change colors. It also has a soft tank, as compared to the hard, brittle water tank with other humidifiers.
