If water drops often appear on the walls in your bathroom, and the mirror fogs up even without using hot water, it means that dampness has firmly settled in the apartment. First you need to check how well the ventilation system is functioning. The most elementary way is to bring a lit candle to the ventilation grilles. When the traction is good, the light deviates in their direction, everything is in order. But if it barely fluctuates or does not react at all to air movements, firstly, all ventilation ducts should be cleaned, and secondly, an appropriate device should be purchased and installed.
Selection of fans
Even with good ventilation, a bathroom fan will not hurt, especially during the hot period of time. It will help to cope with excess humidity, get rid of an unpleasant smell in the bathroom, and improve the overall air space of the apartment.
What power should the device be installed in order for it to work efficiently and at the same time not be energy-consuming? There is a trick here. Need to calculate volumecommon space, the airspace of which should be improved. Multiply the resulting figure by the average number of rooms (from five to ten), from here calculate how much power the bathroom fan needs.
Now about the types of this household appliances:
- Axial wall fans. The entire working mechanism is hidden when installed in the body of the wall. Outside, the front part is left - a grate through which the air intake process is carried out. An undoubted plus of the design is that such a fan for the bathroom fits perfectly into any design of the room, it is organic against the backdrop of the most expensive modern tiles.
- Blade ceiling structures. Their working part is also "recessed" in the cavity of the ceiling, only the axis is outside, on which the "propeller" blades are mounted. This type of air-purifying technology is also useful in any of the most cutting-edge design spaces.
-
bathroom exhaust fan Exhaust fan for bathroom. Often such a device is equipped with a special sensor that monitors and shows the level of humidity in the room. When the humidity level set in the standards rises, automatics work, the fan turns on by itself. The "smart" setting system practically frees owners from the on/off routine. Yes, and with a long absence of the owners, they can not be afraid that dampness will spoil their housing. Therefore, the exhaust fan for the bathroom, although it is more expensive than usual, is still very convenient andprofitable.
- Devices with built-in timer. They can also be left unattended for long periods of time. It is enough to 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 for 2, 5, 15 minutes - as programmed, then turns off, and after a specified time starts working again.
- Models of the combined type - with the installed timer and hydrostat. Naturally, they are quite expensive.
Requirements for ventilation devices
Whatever type of devices are installed, they must have splash protection in their external design and have a system of increased electrical safety. Bathroom fans must have a capacity of at least 100 m3 per hour.
