This is the third de-humidifier that we had over a period of 12 years and far by the best. Our original de-humidifier (expensive circa £400) which we purchased just over 12 years ago was very good and did reduce the double glazed window condensation during the winter periods down to an acceptable level. The original machine was classed as un-economical to repair after 10 years of good service, due to our experience with this company we decided to purchase another machine with a similar specification. The second de-humidifier was not a patch on our original and after a few service visits with no satisfaction we decided to purchase another manufacturer completely. After doing my homework and reviewing a lot of websites like this one we the purchased this machine and all I can say is "it does what it says on the box". We do not have an acceptable level of condensation, we do not have any condensation at all on any windows. The de-humidifier at first was removing 10 - 12 litres per day, it is now removing 6 - 7 litres per day and the house feels a lot fresher as well. Excellent de-humidifier and would not hesitate to recommend to anyone.
