As a quick outline of how I chose fresh-r. My house is north facing and experienced issues with condensation in those rooms. As a chartered engineer I am used to looking at the potential solutions and when I read about the Fresh-r system and spoke to the local representative about its development and functions I was confident it was the correct solution. In particular with it being necessary to install the solution in a house that was 10 years constructed the simplicity of the system without the need for any piping or filters appealed to me. I have not had any issue with condensation and in the 14 months since the units have been in place. The units are in a kitchen and hallway outside the main bedroom and operate a a very low noise level so sleep is not in any disturbed!
