Two Types of De-Humidifiers (Freshbrook SN5)

It's amazing what you find in the back of a cupboard, isn't it? Clearing out one of mine I have come across 2 different types of "manual" compact de-humidifiers that I've not used for a few years but still have a lot of life left in them. There are 4 of the Coopers compact de-humidifiers that have silica gel in them that change colour once they are "full" and you just leave them in a warm place to "recharge" themselves/dry out and again the silica will change colour once they are ready to be used again. I also have 4 (2 white and 2 blue topped) Aero 360 De-Humidifiers together with 11 Aero 360 refill blocks on offer looking for a good home. I don't have a car but I can deliver if you live in the Freshbrook/Grange Park area otherwise it will need to be collection only, sorry. They are in need of a bit of a clean up and come from a smoke-free home. Thank you for reading and I hope to hear from you soon.
