The more efficient dehumidifiers are designed for commercial use but you will find these are fairly bulky, loud and (as a previous answer stated) can be fairly expensive to run. I think a better option (if you will be using it regularly) is to find a dehumidifier that has been designed for the home but is slightly more attractive and concentrated (as in area/floor space). Is it your whole house that is damp or just a certain area? If it’s just a certain area (which I suspect it is) try and contain it by reducing air flow in and out of the room and install a smaller more attractive unit.

If you’re in the UK, I regularly use 4air which is a small company who sell to the trade and I assume homeowners too. I’m sure they will give you some good advice on an attractive unit that will get the job done. I always love a bit of a haggle too and they tend to be relaxed about it.

Try and get the area (m2) or even better the volume (m3) before you speak to them so they can narrow down the units with the power required.
