Why buy me - CD20LE-V5
- Up to a 5-bedroom house: Built for larger UK homes with whole-house damp and condensation.
- Designed for UK homes and weather conditions: Optimised for typical British indoor temperatures and humidity.
- Laundry Mode: Runs flat out at Turbo to a 35% RH target, drying clothes indoors for a fraction of the cost of a tumble dryer.
- Smart Mode: Holds the room at a healthy 50–55% RH and matches fan speed to humidity, so the compressor only runs when it needs to.
- Low-energy running: Costs about 6.5p an hour to run at the current Ofgem price cap.
- Cost to dry a load of laundry: Around 26p for a 4-hour cycle in a small room.
- Sleep Mode: Quiet operation with no bright lights for disturbance-free nights.
- Adjustable humidistat: Set anywhere from 35% to 80% RH in 5% steps, with a colour humidity light on the front (red, orange, green) for an at-a-glance check.
- Three fan speeds: Quiet, Medium and Turbo, plus a dedicated Sleep mode that dims the display for undisturbed nights.
- Swing or fixed louvres: Choose wider coverage or focused drying depending on where you place the unit.
- 24-hour start/stop timer: Schedule operation around work, sleep or an off-peak electricity window.
- Large 5L splash-proof tank: Tank-full auto-stop for safety, or fit a 10 mm hose (sold separately) for continuous gravity drainage.
- Genuinely portable: Castors, a carry handle and an approximate 14 kg weight make it easy to move between rooms.
The electriQ CD20LE is a low-energy compressor dehumidifier built to deal with the everyday causes of damp in a British home – condensation on the windows, washing drying on an airer, and bathrooms or kitchens that never quite clear. It extracts up to 20 litres of moisture a day at its rated condition and holds the room at whatever humidity you set, between 35% and 80% RH.
Because it is a compressor unit rather than a desiccant one, it performs best in rooms that are already reasonably warm – typically above about 15 °C.
Four modes cover the realistic uses. Smart Mode is the default and the one most people should leave it on: it targets 50–55% RH and adjusts the fan to suit, so the compressor cycles only when there is moisture to remove. Dehumidify Mode gives full manual control of the target humidity and fan speed. Laundry Mode runs continuously at Turbo to a 35% RH target until the tank fills – the fastest way to dry a load indoors. Air Purifier Mode runs the fan only; add a HEPA filter to clean the air without dehumidifying.
Practical details matter on a product that lives in a hallway: castors and a carry handle for moving it between rooms, a large 5‑litre splash‑proof tank that stops the unit automatically when full, a continuous drain port for unattended running, a child lock, auto‑restart after a power cut, and automatic defrost so it keeps working as the weather turns.
Smart Mode (default)
On first power-up the unit defaults to Smart and stays there until another mode is chosen. It targets 55% RH and sets fan speed from the measured humidity, running the compressor only when required. This is the recommended everyday setting.
Dehumidify Mode
Target humidity adjustable from 35% to 80% in 5% steps; fan speed selectable. Selecting 35% forces continuous operation - the compressor will not stop until the tank is full. Recommended settings: 50–55% for general domestic use and dry storage, 60% where 50% feels too dry, 70% for unoccupied property.
Laundry Mode
Continuous running at the highest fan speed with a 35% RH target for maximum extraction. Keep clothes at least 40 cm from the unit and clear of the outlet; best results within 1.5 m.
Air Purifier Mode
Fan-only Air Purifier mode; add a HEPA filter for clean air without dehumidifying.
Humidity Display & Temperature Toggle
A front case two-digit display shows room humidity by default; the RH%/°C button cycles which of the front panel and control panel shows humidity and which shows temperature.
The front colour light humidity indicator shows red above 70% RH, orange 60–70%, green below 60%.
Sleep Mode
Hold SLEEP for 3 seconds to dim all indicators except the sleep light and drop to low fan. Quiet operation and no light pollution. Ideal for children rooms.
The SWING button sets the louvres to sweep between 45° and 90° or locks them in position.
Timer & Child Lock
24-hour delayed-on from standby or delayed-off while running, in 1-hour steps. Hold the lock button for 3 seconds to disable the panel.
Auto-restart
After a power cut it restarts on its last settings once the 3-minute compressor protection has elapsed.
Drainage
5-litre splash-proof tank with tank-full alarm and auto-stop, or continuous gravity drainage via the rear port using a 10 mm internal-diameter hose (not supplied). Maximum hose run 1 metre, falling; longer runs or lifts need a condensate pump. The tank must remain fitted for the unit to run, even on continuous drain.
Optional Filtration
HEPA and activated carbon filters are available separately (FIL-CDLEHEPAGM / FIL-CDLECGM) and clip into the rear filter housing. The washable mesh pre-filter is fitted as standard and the unit must never be run without it.

Question from Rachel: Asked on 30/12/2015 I am looking for a dehumidifier to replace an old one that I run on a timer in my cellar 24-7. Because it runs so much I really want a low energy one. It doesn't have to be fancy or attractive as behind a closed door. Main criteria - efficient, low cost and low energy, auto cut off when tank full. What would you recommend? Thanks
