So we are a WG and had the last few years major problems with the humidity, despite multiple daily airing. In order to meet the Lord, we thought of just such moisture killer. Supposedly these things, this effect are intended for up to 50 square meters ... well, what can I say, our rooms have 10 to 25 square meters and we ended up having two of these parts are in the 10sqm room to achieve an effect :(. but was so low that it just did not make more sense to buy any refills. We then borrowed an air conditioner from a friend and does the same thing to another like a dehumidifier. We've also tested and the exhaust air from the air conditioning was warmer than the cold that it blew out, so no additional heating costs, but be careful! 2 hours runtime cost us 15 cents! So you have to expect or through calculate! We reached definitely a decrease in humidity from 60% to 40 % in those 2 hours!
