Advantages of a humidifier

If the air is too dry in rooms where we often spend time, health damages can occur. Amongst other things irritation of the mucous membranes and irritation of the eyes may occur. And not only with us humans, but also with our beloved animals. For example, if the four-legged pets are taken to the office so they do not have to spend the entire day at home alone, they too, like their two-legged owners, are affected by the possible consequences of too dry indoor air. But there are not just living things that are affected by a low relative humidity. Valuable furnishings, antiquities, works of art and floor coverings can also be damaged by too dry air. Especially if the just mentioned objects are made out of wood or other hygroscopic, meaning water-attracting materials it can warp and lead to blemishes or even to a significant loss of value of your valuables.

The single items of the Brune B 300 humidifier


The Blower

The blower can be operated via two manual blower levels or via the automatic function. If you want to determine manually about the blower, select "Low" for a low fan power and "High" for high fan power. If you have the automatic function selected, the electronics take over the complete control of the fan and regulate it depending on the performance requirement either up or down. With the automatic function, you do not have to worry about the blower anymore and you can enjoy your moistened room air peacefully.

The sterilization of air and water by UV C rays

The UV C rays have a highly efficient effect in the destruction of germs. Because this is known about UV C rays, they are already used in the industry of water treatment. The intelligent arrangement of the UV lamp in the Brune B 300 humidifier allows the UV rays to reach the water in the water tank, the sucked in room air, which is located in the device, and the filter medium to effectively get rid of germs. This process, the significant reduction of germs, is completely ozone-free and is harmless to humans as well as to our animals.

The air purification

The additional air filter in the area of the intake of the air first filters dust particles, suspended particles and animal hair. Thereafter, the sucked in air is passed over the water to be moisturized and finally passes through the evaporative filter, which corresponds to a further purification of the air, back into the room. Combined with the sterilization by the UV lamp you have an efficiently and effectively cleaned air, which is much cleaner than before.

The water level indicator

The current water level can be found on the control panel or on the display. So you do not have to remove the tank of the humidifier to be able to see the level of the water. As soon as the tank is empty and there is no more water in it, the unit switches itself off automatically to prevent damage. A flashing light indicates that the water tank is empty and you should fill it up.

The automatic water supply

The automatic water supply is an optional element that you can buy. Adding an automatic water supply to your Brune B 300 humidifier eliminates the hassle of refilling the humidifier, and the humidifier can also be run unattended throughout the day.
