Here’s a list of this VicTsing humidifier’s key features.

Medical Stone Filter

The medical stone filter is responsible in capturing impurities and bacteria that may have lived in the water. The result is a healthier, cleaner, and purer vapor or mist.

What’s a medical stone?

According to this article, it’s a kind of non-toxic compound mineral or medicinal rock whose main composition is inorganic aluminosilicate.

Top Fill Design

Refer to the image on the right to appreciate this humidifier’s “top-fill design.” The advantage is that it’s very easy to fill and clean. Usually, other brands of humidifiers have a removable water tank, but some of them either have a small hole or they need to be refilled from the bottom.

As advertised, you can refill this VicTsing humidifier even when it’s running. Plus, you don’t have to open the lid to add water.

Misting Time

This humidifier is equipped with a water tank that has a 3-liter capacity. It has a powerful maximum mist output of 200 ml/hr, and it can run continuously for 14 hours.

To adjust the mist output, you can simply touch the switch below the VicTsing logo. There are three options to choose from – low, middle, high – and switching between these options require one, two, or three taps on the button. Touch it a fourth time and expect the unit to turn off.
