How DampRid Works

How DampRid’s Moisture Absorbing Crystals Work

The DampRid® crystals are calcium chloride, a type of salt that, like similar salts, attracts moisture. We use the word moisture because it is the most universal term, but the most accurate words for what the product absorbs are humidity or water vapour. The “loose” water molecules of the vapour are more easily absorbed by the calcium chloride crystals than liquid or solid water are. By absorbing water vapour from the air DampRid begins to dry the air, thus promoting the evaporation of liquid water, which, given time, can allow this to be absorbed as well.  DampRid works best in high humidity areas.  Without the humidity to absorb DampRid will not function, or not function as quickly.
