High moisture level can cause harmful effect to your health and your home as well. This excess moisture allows the growth of mold and other harmful airborne microbes to thrive. Using a dehumidifier in your home will help reduce this moisture, preventing you and your home from its adverse effect.
On hearing this, you might want to get a dehumidifier because of its positive effect towards high humidity. But the major concern is how long should a dehumidifier run per day to keep your home at a comfortable humidity level.
For you to keep your home in a healthy state, at best keep the humidity level between 40%-55%. The reason is that growth of mould, mildew and other harmful effect increases at humidity level above 60%.

As you ought to know, different room varies in humidity levels like in the bathroom and drying room; the moisture level tends to be pretty higher when compared to your living room.
Hence, to keep an eye on the moisture level in your home, a hygrometer (damp meter) has to come in handy. Using a damp meter in the room will help you to know the accurate moisture level present.
However, some dehumidifier comes with a LED display and humidity detector to show the current humidity of the room. That way it erases the need of getting a damp meter.
To determine how long a dehumidifier will run per day, read on as we give you great insight.
But first, what does a dehumidifier do ?
Dehumidifiers are household machines designed to extract excess moisture from the air, that way preventing the growth of mold, mildew and other harmful substances.
It works by pulling out moisture from the air with the aid of its vent. This extracted moisture is then trapped into a water bucket or removed through a drain outlet. If the unit uses only a bucket to store up absorbed moisture, you will need to empty when it gets full.
Most models come with great features like the auto shut off function, humidity control and LED display. The auto shut off function helps to turn it off to prevent overflow of water in the bucket. Humidistat offers you the freedom to set the unit to your desired humidity level at which it will shut off or restart. Furthermore, expensive brands have LED display to help you keep an eye of the present humidity and temperature.
How Long Should A Dehumidifier Run Per Day ?
Given that different room varies in sizes and moisture level, how long it will operate may differ.
Dehumidifier setting varies in models. Some dehumidifier comes with a laundry mode setting. With this setting, the unit will run continuously until it lowers the moisture level extremely, leaving the air dry. However, you will need to keep an eye on the damp meter because moisture level below 40% can also cause a severe harmful effect to your health and home.
In damper rooms like your bathroom, drying room and laundry areas, you should run the unit for a longer time with the highest setting. This way, it reduces excess moisture faster. But once you notice that the moisture level falls below 40%, turn off the unit.
Most cases, dehumidifiers with auto shut-off function could also cause the unit to run for a shorter period. The reason is that when its bucket gets full, it turns off the unit to prevent overflow. In this regard, you can leave the unit to run all day, but don’t forget to empty the bucket when it gets full.
Additionally, a dehumidifier can be left to run all day if it has a humidistat. This feature allows you to set the unit to your desired moisture level. This means it will operate nonstop until it drops the humidity in the room to your desired level. Once it gets to this point, it automatically turns off the unit or restarts it when the room gets pretty damp again.
Other Factors That Can Affect the Duration at Which a Dehumidifier Will Operate
There’re other factors that can also affect how long it will operate. Hence to get the best result you will have to consider the following factors.
In a larger and damper space, small sized units will work harder and take longer operation time to remove moisture. This means it will consume more energy, increasing your electric bills in the long run.
However, models with high pint capacity will remove more moisture faster in a pretty damp and large size room. That way, it runs for a shorter time and saves you money on energy bills.
Dehumidifiers will work harder to reduce moisture if warm air from outsides can easily permeate into room When warm air from outside permeates into a room; this causes your dehumidifier to work harder to balance the room moisture level. Hence, always ensure to close all window and door when running the dehumidifier. Also, cover up any openings in the rooms to prevent air from entering in.
In the bathroom and laundry area, Installing vent fans will help to create enough airflow and easy way to let out air. That way, the dehumidifier will work great and remove moisture faster. Furthermore, before using a dehumidifier in the basement, look out for openings in the vent, and pipes. If you find any, cover the openings to block the intrusion of moist air.
Precaution for better efficiency
If the dehumidifier never shuts off, this may be as a result of less maintenance and poor settings. Make sure you clean its coils and vents more often. Remove any visible dust or debris on the vents. If the dehumidifier is pretty old, replace it with energy efficient models. Check the control setting for the moisture level percentage.
Also, the temperature could affect how long it will operate. Not all models operate at a temperature below 45 degrees Fahrenheit. Compressor dehumidifier usually freezes up when used in colder indoor space, and will just sit there without removing moisture. There are dehumidifiers designed to work great in colder indoor space below 40 degrees Fahrenheit.
No Special Regulation
There are no special rules to how it will operate in one day. All models vary in the amount moisture it can remove per day and water tank size. In bathroom or drying room, the unit might run continuously without turning off due to the high moisture present. This means if the moisture present in a room is higher than the unit moisture capacity it may tend to run nonstop.
Also, the extra features in a dehumidifier can also affect the duration at which it will operate.
The running hours of the unit can be affected by many factors as this does not require a strict rule.
With the great insight provided above, you will find it easy to predict how long your dehumidifier should operate per day.
