Kontrol Krystals refills help to combat damp, condensation and musty odours. These refills are suitable for Kontrol Krystals Mega Moisture Trap 1kg.

So, how do they work?

Kontrol Krystals are flakes of calcium chloride (CaCl2) which have a high affinity to water and readily attract excess humidity from the air by a simple chemical process. When used in a moisture trap, the Krystals begin to coagulate (sometimes developing a discoloured crust) and eventually. after a few weeks - depending on levels of humidity/dampness, liquid will begin to collect in the base of the moisture trap. Kontrol Krystals will continue to function effectively for up to 2-3 months after exposure to the surrounding air.

For optimum results, place the moisture trap into areas where there is a damp or moisture problem, replacing the Krystals when the process is complete.
