Practical Boat Owner Magazine tested several dehumidifiers for use in boats and published the results in the December 2009 issue. The DD122 with its desiccant technology was the clear winner, but this has now been replaced by the DD8L model, which has won the award every year since. Its this history of producing award-winning products that keeps us recommending these units.
