I have two pieces likely to suffer from moisture: a storeroom and a windowless bathroom. In the pantry I placed a conventional absorber pad makes very good job. Okay think to empty the container fleet. It was in the bathroom I stashed the bag Seko. Less obvious efficiency. The bag is provided without support, it should be placed in a small container. The powder inside hardens and takes in volume. It's convenient, so it is forgotten. But on the other hand it is also the risk: forget it! And again, efficiency is less obvious.
