But temperature, in particular, has a great bearing on the ability of a dehumidification system to extract humidity from the atmosphere in a productive way. That's because temperature affects relative humidity and dew point which, combined, can alter the dehumidification process.Jun 21, 2018

A dehumidifier is most effective at warmer temperatures and higher relative humidity levels. Relative humidity levels above 60% can cause mold or mildew to grow, resulting in musty smelling air and unhealthy airborne mold spores. The ideal relative humidity level should be somewhere between 30% - 50%.

Should a Dehumidifier Run Constantly? No, there is no need to keep the dehumidifier running constantly. It's generally enough to run the unit when the humidity level is 50% or higher. A good rule of thumb to remember is to maintain a comfortable 30-50% humidity level for most homes.

It is unfortunately a common occurrence that a dehumidifier ends up drying out the air in a home so much that it creates a new set of problems, such as the easy spread of illnesses, cracked, dry skin, and problems with static electricity.May 11, 2015

It also varies depending on the relative humidity levels in the space. An average-sized humidifier for residential space will collect up to 20 liters of water over a day. A commercial, larger dehumidifier can collect up to 50 liters on a given day.

Con: Noise and Heat

Dehumidifiers also tend to blow warm air out of the back of the unit. In the winter, this can be an advantage -- but not so much in the summer. Position the back of your dehumidifier in a doorway so that it doesn't heat up the room from which you are removing excess moisture.

6. How long will it take to get the moisture under control? As long as the dehumidifier you choose is large enough for the area it is working in, and there are no specific damp problems, then a dehumidifier will normally reduce the humidity to the chosen level within a few days to a week.

The best answer would be to run your dehumidifier unit 24 hours a day. However, that could end up costing quite a bit of money, and more than you really need to spend.

• To get the maximum comfort and benefit from your dehumidifier the humidity level should be set at 30 – 50%. If the humidity level is too high, over 50%, it can make mold start to grow or bring existing mold out of hibernation, which isn’t healthy. Reducing the humidity level too low, such as below 30%, can be a waste of your electricity.

• Yes a dehumidifier will help to cool off a room. Humid air feels hot. So when a dehumidifier is used to extract humidity out of the air, the air will feel cooler as a result. A dehumidifier itself does not do anything to cool the room. It is not an air conditioner and does not blow cold air.

• You should only run a dehumidifier in your basement in the wintertime if the room maintains a high relative humidity. To monitor the relative humidity in your basement, hang a humidistat (sometimes called a hygrometer) on the wall. ... If the basement maintains high relative humidity levels in the winter but is too cold to safely run a dehumidifier, use an electric heater for at least a couple of hours each day.

• Be careful if you live in cold weather climates. Since the purpose of a dehumidifier is to attract moisture, the coils can possibly freeze if the weather gets too cold. However, in rooms that are above 60 degrees Fahrenheit, such as a heated basement and the like, a dehumidifier would work just fine.

Temperature : the dehumidifier should be placed on the floor with the least temperature (the coldest floor) in the house, whether upstairs or downstairs. ...
