Humidifiers have come a long way!

I’d never thought I’d be excited about a humidifier, especially one with Bluetooth technology that I can control from my phone! Very easy to set up and go!!

High Tech - So convenient & easy to use

I love this humidifier. I connected it to my Alexa. I can control it from the app on my phone or through voice commands on Alexa. It is just so convenient and a great humidifier.

Best Humidifier Design I've Ever Seen!

This Humdifier is amazing!
The tank is detachable and easily cleaned and filled. It can easily be filled while the tank is still mounted on the base because of the large top-fill.
The mist is extremely fine and is emitted through the largest nozzle I've ever seen on a humidifier.
It is also easily controlled from the front control panel or through a phone app or via voice control using Google or Alexa.
The app gives you more than control over all of the functions, it also provide humidity history and a reminder to clean the unit after each 100 hours of use. (Darn good idea, since there is mold and many impurities in most water systems.)
The base has a 110/120V cord which is much more reliable than a flimsy adapter. The humidifier is extremely well built and priced very reasonably!
