FAQ

Is it okay to run my dehumidifier 24 hours a day?

Are dehumidifiers or humidifiers more expensive to run?

There is little difference in the cost of energy use between dehumidifiers and humidifiers. But the harder they need to work to adjust the relative moisture, the more they’ll cost.

So if you are using a humidifier in an extremely dry space, it will use more energy than if you use a dehumidifier in a moderate climate.

What about commercial dehumidifiers?

Commercial dehumidifiers use less energy than residential-sized dehumidifiers. The size of them means they work more efficiently to remove moisture. Therefore they require a slightly lower wattage per hour to run.

Can a dehumidifier lower my utility bill?

Yes, it actually can lower your energy bill. This is not true for every household, but if you tend to use air conditioning a lot to cool down your space, a dehumidifier will likely help do this by lowering the humidity.

When your home feels more comfortable, you won’t turn the air conditioning on as often. Air conditioners use significantly more energy than dehumidifiers and are considered high-energy appliances.
