This moisture-absorbing product is a safe alternative to electric dehumidifiers. It utilizes 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 it’s captured. The crystals also absorb unpleasant musty odors, helping to create a fresher, healthier environment. They are non-toxic, septic safe and environmentally friendly.
