Put some thought into choosing the right location: Most dehumidifiers release air from the top and sides, so you should place it in an area where there is space around it, and air can flow freely in and out of the dehumidifier. If yours has a hose drainage, also consider whether your drain will be going through a window or hole in the wall. A dehumidifier extracts water by feeding moist air through a powerful fan, then running that air through heated coils to separate the moisture and air.
It then reheats the air and expels it back into the room as dryer air with less moisture. CR offers tips for improving the appliance's performance and efficiency, plus advice on dealing with dampness.

Dampness can cause mold and mildew to grow and spread on your walls and ceilings, and that dampness can weaken wood.
A dehumidifier pulls moisture from the air, collecting the water in a removable tank. But not all are up to the task. Most earn an Excellent rating in our water removal test, meaning they remove the number of pints of water from the air as claimed by the manufacturers.
But our tests also found differences among the models. For example, a dehumidifier that earns an Excellent rating in our humidistat accuracy tests comes close to holding the humidity level you select for your space.
Only a handful in our ratings ace this test. Set the humidity level. The optimal relative humidity level is between 30 and 50 percent, according to Energy Star and 30 to 40 percent in colder areas during heating season. If the humidity is higher than that, it can breed dust mites, mildew, and mold, and trigger allergies. Is there a reason why this might be happening? Thank you!

Would it be advisable to use the dehumidifier after each shower and when drying clothes or would I need to put it on more often?
Thank you. It would be ideal to use the dehumidifier not just after showering but also before and during it. As a bonus they usually have the temperature displayed too. A shower will put out moisture faster than a lot of dehumidifiers can remove it so you may need to leave it running for some time.
Hi, I use my Tatung dehumidifier in a wooden garden shed where I store a lot of office paper records. Hi Simon.
I would prefer for it to run longer at a time, it only runs for about 5 minutes and shuts of again! Can you please tell me what i might be doing wrong with the timer?
It is a Frigidaire. I would really appreciate some help trying to get some humidity out of the family room Thank you. Hello, Rosemarie. Is this recommeded for an unfinished basement which is about 3 years old. Good morning, Dana. The humidity sensors in dehumidifiers and other appliances tend to not be all that accurate so you may find an inexpensive digital humidity gauge to be more helpful for checking it. Curious—just plugged in my first dehumidifier.
Seems to run fine. Does the dehumidifier effect it? Hi there Brady. In severely dry air water evaporates a bit more. I ask because i set mine up last night to help my daughters asthma since we are facing a black mold crisis in our rented mobile home and we got the machine to help her breathe better, we set it up just like directed and by morning the bucket was half full of water?
We ran it continuous for 10 days and were surprised on how much water it collected 50 pints. Over the next 10 days it collected another 50 pints.
We have this unit in our basement under our stairwell and it does get cold in there from possible outside temperatures. It is winter in MN and the temperature outside are dipping below freezing. December 1st we checked the dehumidifier water level and it was dry.
Would this space be too cold for it in winter?
