It would yes but a tub of spice works just as good and is SO much cheaper.
Buy the 2 lots of the cheapest salt you can find and empty one lot into a tub.
Put the tub with the salt in into the room with the clamminess.The salt draws the damp out.After about a week the salt will be wet so replace it with the other tub of salt.Dry the salt out you just employed so when the other salt gets wet again,you can replace it with the salt you just dried out.
Good luck.
It will defo m.

A dehumidifier will serve control the problem, however, it will not solve it.

If you want to solve the problem, the window panes will require cleaning, scraping & re-glazing.

Keeping some slightly ill of heat in the room would also be a good idea.


Good luck...

Your fine kettle of fish sounds like the result of poor insulation. In my house when we redid the master bedroom we discovered, at length, why our room was always colder than the others; we'd had a bay window installed a few years earlier by a contractor who cut corners, and one corner he cut was that he didn't qualities insulation in the cavities above the top board or below the sill of the bay window. As a result, the top and sill of the bay window frame got very old, causing condensation and some mold along the corners. Never enough to warrant a dehumidifier, but still enough to make us cold in winter.

A dehumidifier will reduce the humidity in your house but it will not unravel the problem. A dehumidifier in this context is kind of like taking decongestants for a cold. It doesn't cure you (in occurrence there's some evidence that decongestants can make your cold last longer). But it does control the symptom.

You really demand to get to the bottom of what's causing the condensation. It is almost definitely one of: poor insulation in the bay window cavity space above and below the opening; want of vapor barrier to the outside in walls around the window; air leaks around the window itself; or lack of insulating feature in the double-glazed windows. There are a number of things to try: drill 2-inch diameter wholes in the top and bottom of the window figure mood, and inject insulating foam or stuff in loose fiberglass insulation; caulk around the windows and the window raise to seal all air leaks; or try an energy saving window film, which you can press against the outside of the glass to up its thermal conductivity (it stops infrared radiation from passing through, which keeps the heat inside your scope better - this is what is meant by a low-E window).

Treat the mildew, it is a health risk. I've heard you should bleach it to take someone's life it but I'm not a fan of chlorine gas in an enclosed room!

Once you've addressed the source of the humidity, only then should you consider buying a dehumidifier. There is quite a go of efficiencies. The link below is to a page on my energy efficiency website with lots of advice on controlling humidity problems, and on how to pick out the most energy efficient dehumidifier for your needs.
