The MAX DRY dehumidifier is a special tool for solving the problem of increased air humidity and preventing from its consequences. The set consists of a reusable plastic container and a drying tablet/moisture-absorbent granules operating during a period of up to two months depending on the ambient conditions and the area of application. The tablet and the granules absorb the moisture, bacteria, mould spores and unpleasant odors. The dehumidifier covers up to 30 square meters due to which it can be efficiently used both in apartment houses and in the private sector. Its functioning is based on the chemical composition of the tablet/granules which, absorbing the moisture from the air, transform it into liquid trickling down to the lower part of the container. The dehumidifier operates without connection to the electrical network or use of batteries. The drying tablet and the granules are manufactured from hypoallergenic materials and are safe for the health of people. The MAX DRY BOX plastic container is reusable provided replaceable cartridges are used (a drying tablet or moisture-absorbent granules).
