Just what I needed

I’ve been having a lot of problems with condensation and damp in my garage. To the point that my MdF shelves had completely sagged and gone mouldy. Decided to invest in one of these desiccant dehumidifiers to try and keep that under control. When I switched it in it read 95% relative humidity. It’s now always between 70 and 80. Still not ideal, but considering that the garage still has some drying out to do and it’s poorly sealed I’m happy with the performance. Great little machine.

Thank you so much for taking the time to leave the DD3 a review. We're delighted to learn that it is helping you to reduce dampness and moisture in your garage.
