14oz Bag.These moisture-absorbing sachets are a safe alternative to electric dehumidifiers. They utilize special white crystals which, when exposed to the air, absorb excess moisture and liquefy into a non-toxic, salty brine. The collected liquid will not re-evaporate, so moisture cannot escape once itÆs captured. The crystals also absorb unpleasant musty odors, helping to create a fresher, healthier environment. They are non-toxic, septic safe and environmentally friendly. Depending on humidity, convenient sachets can last for up to six months. The 14oz. Hanging Sachet is designed for placement in hanging lockers. The 6oz. Sachet is ideal for placement under cabinetry in your boat or RV. It features a convenient visual indicator that tells you when it needs to be replaced.
