Those who very sensitive to allergy or asthma have to undertake special measures to prevent mold formation and growth at home. Mold spores, swallowed with a room air, are considered to be an important factor, following dust ticks and flower pollen, leading to bronchial asthma development. Since people spend up to 90% of their time in enclosed space, room air purity maintenance is of a top priority.

Mold fungi better grow in a warm, humid and enclosed space and can produce in this environment up to a million spores in several minutes. The probability, that one-third of them could precipitate in man’s lungs and bronchi wall, is high.
