Residents of apartments periodically encounter unpleasant phenomena associated with the ventilation system. One of them is the appearance of an unpleasant putrid odor. As a rule, the neighbors are not to blame, since their situation is similar. In this regard, one should look for the reason in something else, and then deal with the solution of the problem. There are two such solutions.
1. A universal way to get rid of an unpleasant odor
Regardless of what caused this problem, you can get rid of it using the so-called check valve. Such grilles can always be purchased at building materials stores or via the Internet. The role of the valve is often played by the film on the inside. This will help. An electric hood is also suitable. If the air enters the apartment, and does not draw out through the ventilation duct from it, then the hood will help solve the issue.
Those who are especially economical can build this valve themselves. It is enough to stick the film on the back of the grille - on top or in the corners. The air penetrating into the dwelling will press down the film, which will become a barrier for him and for any odors.
2. Option two
In this case, you should initially find the cause of the undesirable phenomenon. In the overwhelming majority of cases, it is pigeons, which can fly in and simply die in the ventilation shaft. Most often, the problem of unpleasant odors from the ventilation system arises in the summer, and each of us can almost always cope with it without the help of specialists.
