ABOUT HUMIDIFIER

A humidifier is a device that increases humidity in a room. A Comfortable
Indoor atmosphere is achieved at a relative humidity of between 40 and 60%.

It acts as a moisturising agent by relieving dryness and maintaining a level of
comfort during dry winters.

Your appliance automatically controls the humidity level according to your
chosen setting. If the air is too dry, the unit will automatically switch on. As
soon as the desired humidity level is reached, it will automatically switch off.

Excessively low humidity can cause health problems such as dry throats and
noses, chapped lips and other respiratory diseases. Low humidity can also
affect wooden furniture and carpets, causing shrinkage and loose joints. Books
and paper may also shrink, warp and become increasingly brittle.

Benefits of Humidification:

1) Rooms stay clean and germ-free.

2) Makes indoor air more pleasant and comfortable.

3) Ultrafine water particles prevent books, wallpapers and carpets from getting
wet and mouldy.

4) Prevents drying out of mucous membrane, chapped lips and stinging eyes.

time and follow them. Save the instructions for future reference.
