## Customer Reviews

### ⭐⭐⭐⭐⭐ ULTRASONIC HUMIDIFIER -- ABSOLUTELY SILENT
*by M***T on November 20, 2022*

I previously purchased the same model and was very pleased with it. It is easy to operate and runs absolutely silently. It does come with a permanent ceramic filter. However, if you have hard water locally and use it in the humidifier, the filter can eventually get clogged. Your options are: 1) Buy "de-mineralization" filters (from Amazon or the manufacturer - Air Innovations), or 2) Use distilled water. I use only distilled water, which eliminates that annoying "white mineral dust" throughout the room. My only complaint was the humidifier was NOT shipped in a standard Amazon box. Instead, it was shipped in the original mfg. box with my address label stuck on it. This was a bad procedure for two reasons. First, no security (possible package thieves) and second, damage in transit. My humidifier arrived in great condition, but the box had a hole and a few "dings" in it. I completely recommend it for use in small rooms (up to 400 sq. ft.).

### ⭐⭐⭐⭐⭐ Humidifier works very well
*by P***C on March 3, 2021*

The humidifier works very well. It has several output settings which makes it quite versatile. It's easy to use and looks like it will be easy to clean.

### ⭐⭐⭐⭐⭐ Love this humidifier
*by J***N on July 13, 2021*

Easy to use and lasts a while on fill ups of water.
