Why wardrobes get damp
A wardrobe spends most of its life with the doors shut. Air barely moves, and if it stands against an outside wall, that wall gets colder through a UK winter. Meaco's guide explains that water condenses on any surface that is cold enough when there is enough moisture in the air, and that mould can appear at around 68% humidity, well before you ever see condensation.
That is why the signs creep up quietly: a musty smell when you open the doors, clothes that feel slightly cold and damp, spots on the back of a jacket, or a bloom on leather shoes and bags. Absorber tubs help a little, but they need new refills all season long.
Why the Drydon is made for wardrobes
Sized for exactly this job
Meaco says Peltier dehumidifiers will not control much more than a large wardrobe. A wardrobe is the space this type of unit is built for. At 145 × 217 mm and 1.2 kg, the Drydon sits on a shelf or the wardrobe floor.
Quiet enough for a bedroom
No compressor, just a small fan. The manufacturer lists it at 36 dB, so it can sit in a bedroom wardrobe without the hum of a full-size machine.
No refills, ever
Moisture collects in a removable 1,000 mL tank with a window, so you can see it working. Empty it, slot it back and carry on. The unit stops automatically and the light flashes when the tank is full.
Pennies a day to run
Rated at just 22.5 W, it costs about 4.7p a day for 8 hours at today's capped electricity rate. One button, no settings, no app.

How to get the best results in a wardrobe
- Give it space to breathe. Stand it upright on a dry, stable shelf or on the wardrobe floor, with the vents clear of hanging coats and piled jumpers.
- Keep the doors closed. Which? advises keeping doors and windows shut while a dehumidifier runs, so it works on a small volume of air.
- Put clothes away dry. Damp clothes add moisture straight back into the space.
- Check the tank every few days. There is no humidity setting or timer, so it runs until you switch it off or the tank is full.
- Keep the room above 15°C. The listed operating range is 15 to 40°C, which suits a wardrobe in a heated bedroom.
- Big walk-in wardrobe? A single unit suits a standard wardrobe. For a larger walk-in, consider two units, or a compressor dehumidifier if the whole room feels damp.
- Clean existing mould first. The merchant states the Drydon does not remove mould or repair leaks. Clean any marks, then use it to keep the air drier.

Will the Drydon fit in my wardrobe?
The merchant lists it at 145 × 217 mm and 1.2 kg. A third dimension is not published, so measure your shelf or floor space and allow room around the vents.
Is it quiet enough for a bedroom wardrobe?
It has no compressor, only a small fan, and the manufacturer lists 36 dB. The merchant notes that perceived sound depends on placement, so it is quiet rather than silent.
How often will I need to empty it?
It depends on how damp your wardrobe is. The tank holds 1,000 mL. At the rated maximum of 350 mL a day (at 30°C and 80% humidity) it would fill in about three days. The similar unit in a forum owner's wardrobe collected about 125 mL a day, which would take about eight days. It stops automatically when full.
Can I leave it on all the time?
Yes. At 24 hours a day it costs about 14.2p a day, or £4.26 per 30 days, at the current Ofgem cap rate. It switches itself off when the tank is full.
Is it better than moisture absorber bags or tubs?
Meaco says absorber tubs suit a box, drawer or wardrobe, so both can work in this space. The difference is ongoing cost: absorbers need new refills, while the Drydon only uses a little electricity and you empty and reuse the tank.
Does it remove mould from clothes?
No. The merchant states it does not remove mould or repair leaks. It collects moisture from the air. Clean or launder affected items first, then use it to keep the space drier.
