The harmful mold can occur in any place, even in the cleanest and most comfortable home, as it only needs high humidity and lack of ventilation. Often it occurs in winter, in the absence of regular ventilation and presence of condensation. In addition to the unpleasant appearance and its ability to destroy plaster, furniture and wallpaper, mold often causes allergic reactions and respiratory problems. It is therefore an urgent need to take action against it. Use of chlorine preparations, especially in children’s rooms is not desirable! Therefore it is better to replace chemistry with something natural, namely home preparation against mold. Professional mold inspection and mold mapping is especially important in the fight against mold.
