Review: Best Ultrasonic Humidifier - I purchased a Pure Guardian Ultrasonic Humidifier in early 2019 because of the winters and dry heat causing my skin to be super dry and my nasal passages to bleed. The one I purchased then was manual and I keep it in the bedroom. Since it worked great, I wanted one for the living room so I didn't need to keep moving the first one I purchased. This Pure Guardian H4750AR Ultrasonic Cool Mist Humidifier is push button and has the cool mist only, which is totally fine. desertcart had the lowest price and I thought I would try it out to see if it was worth it. This definitely is! If you are looking for a larger capacity cool mist humidifier that is ultrasonic (meaning it does not need filters and gives an even mist) then this is a great purchase. I have been using it for almost a week and it runs all day and night. I fill it up and keep it on the highest setting. It is really quiet and as I stated, it is a nice fine mist. The Pure Guardian are definitely great products. The manual states it comes with a 3 year warranty.
Review: Phenomenal! - This humidifier has been a game changer. It's easy to use, easy to clean, but best of all it is powerful enough to humidify our entire apartment. I refill the tank every other night but keep it running round the clock. As a singer, it has made warming up and maintaining my vocal health so much easier. I didn't realizer how helpful it would be. My boyfriend struggle with painfully dry skin in the winter and it has even helped him!! I did a lot of research before purchasing and I am so happy with my choice!!

### ⭐⭐⭐⭐ Works great but can be improved
*by G***N on January 4, 2022*

I use this device often. It works best with distilled water, or reverse osmosis water, otherwise it creates white dust in the room. I wish there was a better way to adjust low, medium and high output to my preferred preference, not just the setting on the machine.
