Is It Ok To Leave A Dehumidifier On Overnight

I’m sure you’ve heard that it’s best to put your dehumidifier on a timer, but is it OK to leave it on overnight? The short answer is no. In fact, the longer answer is an emphatic “No!” So what’s all the fuss about? Let’s find out!

Is it OK to leave a dehumidifier on overnight?

If you leave a dehumidifier on overnight, it will use more energy and may cause problems for the unit. It’s better to put it on a timer or schedule so that it runs at least once per day.

You should also limit how long you leave your dehumidifier running all day and night. The best way to do this is by setting up multiple different timers for different times of the day (for example: 8 am – noon; 2 pm – 6 pm; 10 pm – midnight). This way whenever humidity levels get high enough during those periods of time, water will be added back into the air instead of evaporating from inside your home or office building through windowsills where there could be mold growth due to excess moisture levels caused by high temperatures outside during hot summer months when people are often outdoors enjoying themselves without air conditioning units installed within their homes yet still sweating heavily while sitting down doing nothing!

Humidity and VOCs

VOCs are Volatile Organic Compounds, which are emitted from many household items. They can cause health effects including eye, nose, throat irritation and headaches. VOCs can also damage your liver, kidney and central nervous system; however there is not enough evidence to determine if they cause cancer in humans.

The most common sources of VOCs include: paints and coatings; cleaning products like solvents (e.g., paint thinners), polishes and waxes; adhesives; glues; pesticides/herbicides used on crops or lawns…and furniture finishes (e.g., varnish).

It’s recommended to put your dehumidifier on a timer.

You can also set your dehumidifier to turn off automatically after an hour. This will save you money and energy because the unit won’t be running when you’re not in the room.

This is especially important if your home has a single-pump system, which uses less water than other types of dehumidifiers. It’s recommended that these units be placed on a timer so they don’t suck up too much electricity while they’re not being used!


Dehumidifiers are great for keeping your room dry, but they can also affect the air quality. It’s important to know how much moisture is in your home and how long it will take for it all to evaporate so that you don’t end up breathing in harmful VOCs. If you want to ensure your dehumidifier doesn’t overwork itself overnight or if you just want more peace of mind during humid summers months, then set it on a timer so there’s less risk of having an unhealthy indoor environment.
