If drops of water often appear on the walls in your bathroom, and the mirror fogs up even without using hot water, then the dampness has firmly settled in the apartment. First you need to check how well the ventilation system works . The most elementary way is to bring a lit candle to the ventilation grilles. When the draft is good, the light deviates in their direction, everything is in order. But if he barely hesitates or does not react at all to air movements, - firstly, you should clean all ventilation channels, and secondly, purchase and install the appropriate device.
Fan selection
Even with good ventilation, a
fan for the bathroom does not hurt, especially during the hot period of time. It will help to cope with excess moisture, relieve unpleasant odors in the bathroom, and improve the overall airspace of the apartment.
What power should the device be installed so that it works efficiently and at the same time is not energy-intensive? There is a trick. It is necessary to calculate the volume of the common room, the airspace of which should be improved. Multiply the resulting figure by the average number of rooms (from five to ten), from here and calculate how much power a fan for the bathroom needs.
Now about the types of this household appliance:
- Axial wall fans . The entire working mechanism is hidden when installed in the body of the wall. Outside, the front part is left - the grille through which the air intake process is carried out. An undoubted plus of the design - such a fan for the bathroom fits perfectly into any design decoration of the room, seamless against the backdrop of the most expensive modern tile.
- Bladed ceiling structures. Their working part is also “recessed” in the cavity of the ceiling, only the axis appears on the outside, on which the “propellers” blades are mounted. This type of air cleaning technology is also convenient in rooms with any ultramodern design.
- Exhaust fan for the bathroom. Often such a device is equipped with a special sensor that monitors and displays the humidity level in the room. When the humidity level set in the standards rises, the automation is activated, the fan turns on itself. A “smart” tuning system practically frees owners from the on / off routine. And with a long absence of owners, they can not be afraid that dampness will spoil their housing. Therefore, the exhaust fan for the bathroom, although it costs more than usual, is still very convenient and profitable.
- Devices with a built-in timer. They can also be left unattended for a long time. Simply set the on / off parameters, the standard period is from 2 minutes to 20. That is such a fan for the bathroom turns on, works 2, 5, 15 minutes - as it was programmed, then it turns off, and after a specified time starts working again.
- Models of the combined type - with installed timer and hydrostat. Naturally, they are quite expensive.
Ventilation Requirements
Whatever type of devices are installed, they must necessarily have protection against splashes in their external design and have a system of increased electrical safety. The performance of fans for bathrooms should be at least 100 m3 per hour.
