The basis of ventilation and good indoor air is that air is constantly removed from the apartment, and it is replaced by fresh air coming from outside. The housing locations of TYS have power ventilation of exhaust air.
Exchange air vents, i.e.vents which let fresh air into the apartment from outside are located near the windows. Exhaust air vents, i.e. vents leading exhaust air outside, are usually located in the kitchen, bathroom and for example in the walk-in closet. It’s important that both exchange air vents and exhaust air vents are kept open and clean.
Exchange air vents
An exchange air vent must never be fully closed or for example blocked by tape. If the exchange air vents are blocked ventilation starts to suck exchange air through the next easiest way, such as mail slot or sewer. Many exchange air vent models have different positions which can be adjusted for example according to the outdoor temperature (winter and summer position, see video above). If a vent is in the open position but no fresh air comes in, fill in a notice of defects form. If there is dust in the vent, you can vacuum-clean it. Regular cleaning of the exhaust air vent is the tenant’s responsibility.
Exhaust air vents
Vents gather dust over time and they must must be washed if needed. A vent must never be adjusted when being washed but it must be wholly pulled out (off its collar) by twisting it counterclockwise and washed carefully for example with dilute dish washing liquid solution (see video above).
You can easily test the function of an exhaust air vent: put a bit of toilet paper/ kitchen paper over the opening of the vent. If the bit stays stuck on the vent, the ventilation functions as it should. If the bit falls down instead, the ventilation out of some reason doesn’t remove air from your apartment and the reason must be found out.
It’s recommendable to leave the bathroom door ajar after a shower and during the drying of laundry so that the vent fluently receives replacing air from elsewhere in the apartment: the bathroom gets dry sooner, and the ventilation doesn’t pull stinking air out of the sewer instead.
Usually there also is one exhaust air vent, it may be located above the stove or inside the cooker hood. If there is a cooker hood in the kitchen, the tenant is responsible for its regular cleaning with dilute dish washing liquid solution or in the dishwasher (see video above).
