It has a 1500ml capacity which means you won’t have to change it every day, even if you leave the dehumidifier running. Unlike other dehumidifiers I've tested, this unit doesn’t kick out hot air, regardless of how long it’s on. This reusable dehumidifier doesn’t run on any electricity, so you can place it where you like, and it will still collect a lot of moisture from the air.

We tested each dehumidifier for at least three days and kept an eye on energy costs, how noisy it was and how well it performed. Lightweight, small, and oh so quiet, this dehumidifier comes in sleek black or stylish grey, with the aim of blending into your living space. The water tank is situated at the front of the unit and there’s a small window, so you can keep an eye on the water level, but when it’s full the LED light will light up to indicate it needs emptying.I also used the dehumidifier in my bedroom which is prone to developing condensation on the windows in the morning.

The 600ml water tank is the right size for the amount of water that’s extracted and means it won’t have to be emptied often. It didn’t really get rid of any odours associated with cooking like other dehumidifiers have, but this design doesn’t have an air filter, so that’s understandable. If a collection service is opted for, the item will normally be collected within 10-21 working days. The tank is easy to empty and replace once it’s full, and the use of a peltier system means it doesn’t affect the temperature of the room.

As a general rule, a compact dehumidifier will suit a small space, while a larger area requires a more generously sized dehumidifier with a big enough tank to efficiently extract sufficient moisture. With three modes - strong, sleep and auto - and a timer function, the CONOPU 2300ml Dehumidifier gets the job done with minimal fuss. Plus, there’s an automatic switch-off function, so there’s no need to worry if you leave it running when you’re not around. The dehumidifier did a good job of drawing condensation away from the mildew-prone spot next to the window.
