5 Best Low Watt Dehumidifiers For Your Home


A dehumidifier is an appliance that removes moisture from the air, generally to improve the indoor air quality.

Dehumidifiers work by sucking in warm currents in the air, cooling them until they condensate, then collecting the moisture that results. This moisture can either be collected in a receptacle (bucket) or removed from the room through a drain.

An extreme excess of moisture can cause mold, mildew and promote the growth of certain bacteria, which can trigger respiratory problems or irritate allergies for some people. That’s why it’s always a good idea to have a dehumidifier.

How many watts does a dehumidifier use?

Most regular-sized dehumidifiers use between 500W – 800W. This is, however, dependent on their size and how many liters of water they can draw.

Smaller dehumidifiers will, naturally, accumulate less water, and can run on lower wattage – anywhere from 150W – 300W.

Does a dehumidifier use a lot of electricity?

In general, dehumidifiers aren’t very high energy consuming appliances… if used for a couple of hours a day, that is.

And although the fan part does produce heat – a major contributing factor in why devices require higher wattage – it doesn’t produce lots, and so can run on a few hundred watts per hour.

How much does it cost to run a dehumidifier 24/7?

The issue is that, in most cases, a dehumidifier will need to stay running for several hours a day (or possible the full day) in order to be effective at removing moisture from the air. Those watts start to add up.

How much electricity does a dehumidifier use?

Let’s say that you’re using a 500W dehumidifier all day, every day, that works out at 12kWh per day, or 360kWh per month.

A kilowatt costs roughly $0.20 (though this number varies depending on where you live in the world). So that’s $2.40 per day, and $72 per month. A hefty sum, huh?

Choosing a dehumidifier

As the above example has shown, it can get pretty expensive to run a dehumidifier if you plan to use it for several hours a day. That’s why it’s important to choose a dehumidifier with low wattage, ideally something below 350W.

We’ve selected a handful that meet this requirement yet still perform well even while consuming less power than their high-powered counterparts.
