Very disappointed in the product. I had it on in a damp room and it only removed some of the water. It doesn't live up to 18ltrs per day. I only got 1 litre in 3 days. Then it broke down. I sent it back and it was repaired and then it seemed to work as in the lights were on and noise from the fan but no water in the collection tank. So it was sent back again. When it came back there was smoke coming out of the front. So it went back again. I wish I had never bought it. It's a horrible product and the last time I buy British for the sake of patriotism.
