you can use it to make the air drier in your basement
Basements often collect humid air more than the rest of the house. Humidity can encourage the growth of mold and other problems. A dehumidfier draws the moisture out of the air.
You should run it only when it's display tells you the air is humid.
Get a humidity gauge (Is there a better word for this?) and put it in your basement. Watch it for a few weeks. If it is consistently high (I'd say abouve 75%) you may want to invest in a dehumidifier.
You can have a dehumidifier AND a sump pump, and still have water in the basement. A dehumidifier helps decrease the humidity due to the lack of ventilation in a basement. A sump pump facilitates drainage of water, as a basement has no natural drainage. Neither prevents water from coming into the basement through the walls or the seams of the floor and walls. If you have problems with water coming into the basement, consult a professional who can advise you of the cause and explain the options to remedy the matter. Neither a dehumidifier nor a sump pump will totally insure a waterproof basement. Dehumidifiers simply remove dampness. Sump pumps do not remove damnpness but will drain off water.
When waterproofing your basement you could use a basement dehumidifier, a Sump Pump, or a window well drain. All of these will help with your goal of waterproofing you basement.
My grandfather keeps a dehumidifier running in his musty basement, all through the rainy season to reduce chances of mold.
I'd give it 3 days.
Buy a dehumidifier. Rent an ozone generator. Info on my site.
A dehumidifier. Also there are several mold killing sprays and powders you can use. if it continues then you should have a plumber look at your pipes for any leaks.
Dehumidifier should be cleaned yearly. Proper maintenance is important for the dehumidifier to work properly. anonymous@oola.com
