Leaving your dehumidifier on all the time can result in dehumidifying too much, leading to a dry indoor environment. It can cause dry air, leading to respiratory issues, dehydrated skin, and static electricity.
Humidity level
If the dehumidifier has enough power, it will regulate high humidity in the whole house as long as you keep the doors to all rooms open.
Setting the dehumidifier to the wrong humidity level can be counterproductive. Too low a setting can make the air excessively dry and uncomfortable, while too high a setting won't effectively combat humidity-related issues.
Signs that indicate a home is too dry include: 1. Dry or irritated skin, lips, and throat. 2. Increased static electricity, causing clothes and hair to cling. 3. Frequent static shocks when touching objects. 4. Cracking or warping of wooden furnit...
Dehumidifiers are not very effective in extremely low temperatures. This is because dehumidifier coils attract water vapor, and if the temperatures drop too low — below 42 degrees Fahrenheit for example — the vapor would freeze, damaging your machine.
Mold needs 55% or higher humidity in order to grow. Also, remember that reducing humidity below 30% isn't a good idea, either. This can cause health problems, making your eyes nose and skin dry, and exasperate lung and skin conditions.

1. Yes, It Is Safe to Sleep with a Dehumidifier On. It is perfectly safe to sleep with a dehumidifier on. In fact, leaving your dehumidifier to run all through the night can be highly beneficial for your health and comfort, assuming you don't have any pre-existing medical conditions.
Research shows that the ideal relative humidity for your home is between 40%-60%. However, to discourage the growth and spread of mold, levels should be kept below 50%.
The bigger the dehumidifier (and the higher the wattage), the more watts it'll generally use. Large ones can use up to 500 watts, while the smaller models usually only use about 22 watts. All of these factors can also impact your dehumidifier's energy use.
Keep Your Dehumidifier Away from the Walls
It's easy to assume the best place to put your dehumidifier is against the wall. But it's not! Dehumidifiers suck in and expel air using vents. Blocking any of these vents can reduce your dehumidifier's effectiveness.
The biggest reason for high humidity in your home is moisture intrusion from outside. This could be through leaky windows, leaky floors, wet crawlspaces, leaky HVAC ductwork, or very small leaks in all of these areas that form a large amount of leakage when combined.
Cons of Dehumidifiers
Dehumidifiers collect water meaning they need to be regularly emptied. They also need to be regularly cleaned otherwise black mould can start to grow on the machine , which can induce a wide range of health problems including allergic reactions, lung problems and irritation.
So, what is the best humidity setting for a dehumidifier? To prevent mold growth and keep your home's relative humidity at a comfortable level, we recommend aiming for 30%-50% humidity in your home.
The temperature in your home
Keep doors of unheated rooms open to allow some heat into them. Ideally your home should be heated between 18 to 21 degrees Celsius, but older people, babies and people who are less mobile may need it to be warmer.
During the summer months, many homeowners rely on their air conditioning (AC) system to cool down the home and remove the humidity from the air. While for many homes, the AC will be sufficient, for those in hot and humid climates, a dehumidifier can help carry some of the workload.
Purchase a Hygrometer
Hygrometers are widely available and the easiest way to get an accurate reading. According to Energy Star, the humidity level in your home should stay between 30-50%. A hygrometer will allow you to monitor your humidity levels, which you should do regularly to ensure consistency.
However, we always recommend leaving your dehumidifier running 24/7 [see below]. It will turn on and off as needed (depending on the relative humidity level) and therefore continuously prevent condensation." See what our experts say about what size dehumidifier you need.
Use of Heating Systems
Nonetheless, these systems are notorious for removing natural air moisture while heating your home. Whether using radiators, space heaters, or forced air, your homes humidity level will significantly reduce, creating a dry and unpleasant indoor setting.
Use dehumidifiers and air conditioners, especially in hot, humid climates, to reduce moisture in the air, but be sure that the appliances themselves don't become sources of biological pollutants. Raise the temperature of cold surfaces where moisture condenses. Use insulation or storm windows.
