To reduce the high humidity of a new building, I have dealt with the issue dehumidifier. Originally I thought of the dehumidifiers that work with pellets. However, this idea I am because of the time (together up here even 2 liters, it can take several weeks) and the costs (a refill binds approximately 2 liters of moisture and costs about 5, -) strayed. A simple calculation: In order one or more rooms by about 20 liters of water to dehumidify (who has moved into a new building and know how much construction water consumed here knows what I'm talking about) one needs therefore two months and 10 dehumidifiers (parallel) the - expects you only the cost of the refill, cost around 50.00. This amount of moisture draws the WDH-610HA away in less than a week. The statement "up to 12 liters per day," I think is exaggerated, this may work in the tropical rainforest, but in about 10 hours creating this device easy 2 liters, and this is certainly also depends on how high the actually binding moisture is. Compared with the granulate solution that appears cheaper at first, I'm definitely happy to have opted for this device. Meanwhile, we have a room humidity that is between 55% and 60%. I stroke the amount of water that has been removed from the air this device that the granulate solution would in any case have been much more expensive and would furthermore also lasted considerably longer. From me 5 stars - an absolute buy recommendation.
