I have one of these
https://www.meaco.com/products/meacodry-abc-range-12l-dehumidifier
Which seems to be the same extraction rate but a bigger tank (2.6l vs 1.5l) and quieter.Anecdotally, if I set if going in a room with 2 loads of washing overnight the clothes will be dry the next morning and the tank full.
Although if it is going in a room that used to be a toilet you might have somewhere to just drain direct via a hose (which they both seem to do).
Was looking at this one https://uk.trotec.com/shop/comfort-dehumidifier-ttk-33-e.html
Would you suggest biggerer?
