ABSODRY is all about an effective way to dehumidify a space, using a design moisture absorber. Our special dehydrating crystals draw moisture from the air and allows it to condensate in the bottom part of the moisture absorber. When the absorber is full and the crystals are consumed, just start over with a new ABSODRY refill, and ABSODRY will continue to "devour moisture". How it works Our special dehydrating crystals draw moisture from the air and allows it to condensate in the bottom part of the moisture absorber. Simple and effective.
