Suitable for use in living spaces of up to 15 m sq ideal for caravans, living rooms, kitchens, and bedrooms. Like iron filings to a magnet, the hygroscopic attracts and removes moisture from the air, helping prevent damp and associated mold, mildew, and unsightly stains and aiding in the neutralisation of odors. The dehumidifier is ideal for use throughout the household, ideally one per room where there is a damp problem and particularly suited for use on windowsills assisting in the prevention of condensation. The system is noiseless and requires no electricity or batteries. 500 grams are effective for 6 to 8 weeks depending on ambient conditions and absorb twice their weight in moisture. The moisture trap is calibrated for ease of use and once full, you can use the ergonomic spout to safely pour away collected liquid. Always read instructions on the product packaging before use.
