TCP Smart 20L DEHUMIDIFIER
Home and Garden February 4, 2026
This time of year, it can be really tricky to get your clothes dry after washing, and damp clothing hanging around your home can quickly lead to a damp house. The TCP Smart 20L Dehumidifier is a solid choice if you want to tackle damp, condensation and musty air in medium to large rooms without too much fuss. It can remove up to 20 litres of moisture a day, which is useful for spaces like kitchens, living rooms, utility areas or basements where moisture can build up and cause problems like mould and odours.
It features smart connectivity which allows you to control the unit via the TCP Smart app on your phone wherever you are, and it also works with voice assistants such as Alexa and Google Home, so you don’t even have to move from your chair if you don’t feel like it. You can set target humidity levels, timers or schedules becomes with this remote control, and the digital display keeps you informed of progress.
The dehumidifier has a reasonably large 4.3–4.5 litre water tank with a transparent indicator so you can see when it needs emptying, and an auto shut-off feature stops the machine when the tank is full. If you want continuous operation without pausing to empty the tank, there is also an option to connect a drainage hose.
Daily use is straightforward thanks to two fan speeds, an adjustable humidistat and a built-in timer. It runs fairly quietly for its size, so it won’t be too intrusive in living areas. It also has an auto defrost and auto restart features that add reliability, especially if the power cuts out or the temperature drops.
It’s worth noting the smart control can take a bit of time to set up and the unit is not the quietest on the highest setting, however the TCP Smart 20L does balance performance and convenience well. For anyone looking to reduce indoor humidity, prevent damp or speed up laundry drying inside, it provides capable day-to-day humidity control without breaking the bank. RRP £210
