The DampFree Hanging Absorber Pouch creates and easy, hands-off approach to a damp free environment. The non-toxic crystal formula works by gradually pulling moisture from the air and protecting against dampness, rust and musty odours that can damage your clothing and other stored items in your wardrobes, closets, cupboards and any other enclosed spaces. To use, simply remove the pouch from the carton and plastic packaging, unfold, and hang with the paper filter side hanging outwards, ensuring there is enough space for circulation. The moisture-hungry-magnets will then absorb excess moisture from the air as they dissolve and prevent musty odours. When the crystals have dissolved completely, discard the pouch while holding upright and simply replace with a new Pouch. Each Hanging Pouch can absorb up to 800mL of moisture and lasts up to 75 days depending on temperature and conditions. Overly humid environments also present opportunities for mould and mildew growth, leading to allergens that trigger Asthma and other respiratory problems. Do not use near metal and leather goods.
