Get the DD1 Classic if…

  • Garage, loft, conservatory or unheated room.
  • You keep the heating low.
  • You'll carry it room to room.

Get the Arete One 20L if…

  • A normal, heated home.
  • You want lower running costs.
  • Bigger damp problems.

Why the Arete One 20L wins

In a heated home the Meaco removes more water for less electricity. In a cold room a compressor slows down, and the desiccant DD1 keeps working.
