Dehumidifiers are expensive in power consumption, I don't know which model is more effectively. I'm living in SEA, and get humidity level to 50% 24/7 in my studio equally to double my monthly electricity bill.
- Cthulhu_ 8y agoI don't know if these are effective, but in my country we have passive dehumidifiers which are basically containers with a load of salt or something like that which draws the moisture out of the air. Good enough to keep caravans in storage mold free. Probably not good enough for e.g. living rooms or actually moist locations, but maybe it scales up. Of course, you'd then need a lot of salt or whatever the stuff is.
- majewsky 8y agoI used the passive variant that you explained in my previous apartment and while it may be effective at keeping humidity down, it's not very effective in bringing a high humidity down. I got an electric dehumidifier and it's drastically more efficient. It pulls over two liters of water per day out of the air if the air is sufficiently humid. I've since moved, so I don't use it routinely anymore, but I still have it and occasionally use it to speed up the drying of clothes on a drying rack.

The problem is, once the calcium chloride has absorbed the moisture from the air and is saturated, you have to take it out and dry it to make it effective again. That might be cheaper (in terms of energy) than refrigerant phase-change dehumidification, but it's a lot more labor intensive.
