The Moisture Killer dehumidifier from Symple Stuff works against moisture, mould and unpleasant odours. It is ideal for rooms of up to 20 square metres and can also be used to dehumidify textiles, furniture, cars and walls. It contains 250 grams of potassium chloride, which begins to remove moisture from the environment immediately after the dehumidifier is set up. The water, which collects visibly in the container, is proof of the effectiveness of the Moisture Killer. The dehumidifier works entirely without electricity and removes moisture from the air with one filling lasting for up to four weeks. Refill packs are easily available, so dehumidification over several weeks and months is also possible. The set includes two dehumidifiers in neutral grey. For long-term or permanent dehumidification of rooms, Symple Stuff now also offers a large refill pack for the Moisture Killer dehumidifier. This jumbo pack contains four blocks of potassium chloride (250 grams each). This means that a total of one kilogram is available to provide fresh, pleasant indoor air for four months. The dehumidifier’s mechanism of action is based on biological and chemical principles similar to those of natural desiccants, such as sea salt. This Symple Stuff dehumidifier was tested in a laboratory and works in an environmentally friendly manner.
