4th tip: of course. Ventilating!
Ventilating the place has proven to be a quick and effective means of exchanging humid air with fresh air. If you air your bathroom regularly, you can help prevent mould from forming. For ecological reasons, the window should not be left open for hours during the winter months, as you will otherwise unnecessarily waste heating energy. Ventilation is particularly effective when open windows cause a draught. To do this, it is best to open the bathroom window and the door as well as a window in another room so that the moisture can escape quickly. If you don’t have a window in the bathroom, switch the ventilation unit on for a while. You can also open the bathroom door and a window in the room opposite. To ensure the humid air leaves the premises and does not accumulate in other rooms, doors to other rooms should remain closed.
5th tip: replace the ventilation filter
In bathrooms without windows, a ventilation unit installed by default is known to help eliminate unpleasant odours. The unit’s performance determines whether and how fast the air in the bathroom is fresh again. If, however, the ventilation is outdated or broken, it can also actively cause unpleasant odours in the air. You may experience unpleasant smells in the bathroom if the filter is blocked or the ventilation defective. Instead of fresh air being brought in, the defective unit brings the unpleasant air back into the bathroom. Whatever the situation: cleaning, maintenance and possibly a new product are certainly worth your while.
