I have cheap crystal type Unibond moisture absorbers in all 3 bathrooms. They do a great job all year round but they won’t, and aren’t intended to, absorb moisture from the rest of the house or the laundry.
After reading recommendations from Which, Gransnet and other online forums I bought a Pro Breeze 12L/day model. It arrived on Monday and has dried 2 loads of washing in no time. It is on for a couple of hours a day. You can use it on continuous drainage if it’s near an outlet or emptying into a large container but that’s no good to a wobbly weakling like me. It has casters so is easily moved as required. It has a 2L tank and I can manage to empty that myself. I empty it once a day after it’s finished running. It won’t overflow, it beeps a warning and switches itself off when it gets near the top.
I had a good think about where and how I wanted to use it, accessibility given the afore mentioned wobbly weakness and visual impairments, and checked the energy use. This one works great for me but others may have different needs.
Hope this helps someone.
