Dehumidifier for window condensation: when it is the right buy
A dehumidifier helps window condensation when the room air is wet. Wipe the glass, treat any mould in the tracks, then run the machine. It will not, on its own, fix a broken window seal or mould you have already left in the channel.
Treat the surface you can reach with First Light. Keep a still room in play with the Protection Kit. The condensation method itself lives on how to stop condensation.
Size and where to stand it
Pick a unit that can run for hours in the room where the glass actually sweats, usually a bedroom or lounge, and empty the tank (or plumb a drain) so you will keep using it. Stand it where air can move around it, near the wet glass, not buried behind curtains.
We have not lab-tested a ranked list of dehumidifier brands, so this page will not invent one. Buy for capacity, a tank you will empty, and a noise level you can sleep near if it is a bedroom machine.
Treat the tracks, then dry the room
First Light is the treatment for mould in a window track or on a sill you can reach. Lab tested: 99.2% on direct contact. The Protection Kit is for the still room while you bring the moisture down. A dehumidifier is the machine for wet air, not a substitute for that clean.

What a dehumidifier will not fix
A failed sash or double-glaze seal still leaks cold and keeps the pane wet. A heavy curtain hard against the glass still traps a cold, wet pocket. Mould already sitting in the track still has to be cleaned. Use mould on window sills and frames for the sill and the frame face, and mould on window tracks for the sliding channel.
If you want the science of whether a dehumidifier stops mould, that is do dehumidifiers stop mould. If the machine is for a bedroom more than for the glass, use dehumidifier for bedroom mould.
Pair it with a room treatment
A dehumidifier takes water out of the air. It does not treat a stain, and it does not run oils. Once the glass is drier, keep a shut room in play with the Protection Kit. First Light stays on the tracks and sills you can reach.
