Q & As

John Lewis Large Moisture Trap 4.1 5 9 9
amazingly effective We have recently moved into a house which is really damp from condensation and inadequate ventilation. We had a small spill on the carpet and the area where I cleaned it up was still wet two weeks later!! We put one of these next to it and within a week it had a centimetre of water in the bottom and the carpet was finally dry. I am buying some more to see us through the winter!! Great product and so good to see that you have refills available too. Thanks John Lewis. 20 August 2013
Very effective By far the best product I've found for dealing with condensation in a wardrobe - since it has been in there, the issue has cleared right up. Easy to use and refill, though instructions on the packaging at the start would have been helpful. 29 April 2013
No instructions No instructions came with this item, don't know how many crystals to use and how often to replace them 13 January 2013
The only thing it has trapped are the crystals! After reading the positive remarks regarding this product I was relieved to find something that would absorb the condensation from my bedroom windows overnight without the noise of a de-humidifer. This was not the case, it has now been two weeks since I have purchased Moisture Trap and the only difference is that the crystals have hardened and I am still having to wipe my windows with towels. Very disappointed, complete waste of money. 10 January 2013
Excellent purchase - it really works! I bought this for my drying room about six weeks ago because of too much condensation at times in the winter months. (There isn't an extractor fan in the room and I don't use a tumble dryer.) This moisture trap has been a very effective remedy and since using it condensation is a thing of the past! I still can't quite believe how good it is - and so cheap too! 01 January 2013
A very good damp trap You pay a little extra for quality and moisture traps are no exception. It does exactly what it is supposed to - traps a lot of moisture with no mess and no leaks. Very good product that everyone should have under their kitchen sink. You might not think you suffer from damp issues, but trust me - you do! 21 November 2012
product quality exactly as described and very competatively priced 19 October 2012
Good value! These dehumidifiers catch a surprising amount of water, however fill up quickly. 01 February 2012
