How much moisture does the MDDO12 remove?

Midea rates it at 12 liters per day, which suits rooms of about 20–35 m². In a very damp or larger room it will run longer and need emptying more often.

Is it quiet enough for a bedroom?

Midea rates it at 35–39 dB, roughly the level of a quiet fridge hum. Most people can sleep with it running, though the compressor cycles are audible in a silent room.

Can it drain continuously?

Yes, it has a continuous-drain outlet, so you can run a hose to a drain and skip emptying the 2.5 L tank. The hose is normally sold separately.

How does it compare with a 20 L dehumidifier?

A 20 L unit removes more water per day and copes better with large or very damp rooms. The MDDO12 is smaller and lighter, and better matched to a single bedroom or living room.

Does it work in a cold garage or unheated room?

It uses a compressor, which loses efficiency as temperatures drop. It is designed for normal indoor rooms; for unheated spaces below about 15 °C a desiccant dehumidifier is the better choice.
