The package includes a dehumidifier plus an extra pack of the refill tabs. The dehumidifier is designed for use in living spaces of up to 30 square meters. This product is ideal for winter lockups, caravans, motor homes, and other leisure vehicles. The dehumidifier is also ideal for use in living rooms, bedrooms, kitchens, office spaces, and storage units. The hygroscopic refill solutions allow you to replenish the dehumidifier again and again. Like iron filings to a magnet, the hygroscopic attracts moisture and assists in the prevention of condensation, mold, mildew, and unsightly dampness. This typically lasts 6-8 weeks depending on ambient conditions. The dehumidifier can be emptied safely through the integral pouring spout and the contactless refills are simple and easy to use. Always read instructions on the product packaging before use.
