The optimal relative humidity for human living is 40-60% RH. Creating a comfortable environment with suitable humidity can let you breathe easier, reduce coughing, and prevent dry skin and sinuses.

Reduce Static Electricity
The level of static electricity depends on the humidity of the surrounding air. Drier air leads to more static electricity and discomfort between your skin, clothes, even people’s physical touch.

Prevent Dry Skin
Thanks to its top-fill design and wide opening of the water tank, you can easily clean out TOSOT humidifier. Replace the water in the water tank to prevent the growth of incrustation.

Enhanced Aromatherapy
With aromatherapy function, you can relax and breathe air with your favorite fragrance by adding a few drops of your selected essential oil into the tray.

A full water tank will run continuously for 28 hours on low, 20 hours on medium, or 12 hours on high.

Oil Diffuser
Do not add scented oils directly to the water tank as this may degrade the internal components. Always use the fragrance box on the rear of the humidifier base.

4L ultrasonic cool miss humidifier
Excellent! Super easy to fill and clean!


Great humidifier and easy to use
The machine is very quiet and does a great job of dispersing the mist through the room! I highly recommend this product!

Very high quality humidifier
The market is truly full of the humidifiers, you can see the prices are very different. Tosot humidifier is absolutely a higher quality if we consider it’s low price. I have my humidifier for my dogs, children and the air is absolutely better, you can feel it immediately after turning the humidifier on. I let it work with the purifier and the A/C and I no longer can breathe outside. It’s has literally no noise and is super easy to clean.

1. Do I have to use purified water?
It is not required to use purified water, but buildup of hard-mineral deposits in the water tank could be reduced by using only distilled, mineral-free water and frequent cleaning.
2. What is a carbon filter? How often should I clean?
The Carbon filter is a black, sponge-like material which is for the air intake. This filter may attract large quantities of dust or other debris from the surrounding air after continued use, depending on your local environment. We recommend doing a basic cleaning every week.
