Most Energy Efficient Dehumidifiers of 2021 – Top Models Reviewed

| Last Updated: October 7, 2021

A lot of us view conservation as an abstract idea. But in the HVAC space, buying an energy efficient dehumidifier could save you hundreds of dollars in utility bills.

It lowers your carbon footprint, and is good for your health as well. Devices that use minimal electricity have extended lifespans, because there’s less wear and tear, so you can go longer periods before replacement.

But just because it says ‘energy efficient’ on the box doesn’t mean it is. To be sure your dehumidifier works as advertised, you need intense research. Fortunately, we’ve done the tough part for you, generating a list of genuinely green gadgets. It’s not absolute, but it’s a good place to start, so let’s look through our selections together.

Characteristics of Our Favorite Models

Many experts say relative indoor humidity should be 40% to 60%. In the summer, your readings should approach the upper limit, while lower figures are preferable over winter. Dehumidifiers are essential for bathrooms, basements, crawl spaces, and other damp areas. And picking your favourite should be driven by practical criteria. Let’s explore some of those factors.

Temperature Settings

When it’s warm, the air can hold extra moisture, so relative humidity may be higher. At the other end of the spectrum, lower temperatures contain less liquid. It’s why the air feels drier during the winter. That said, there are parts of your home that are colder, like basements and unused stores. If temperatures in these spaces go below freezing, your dehumidifier may frost over and stop working. Look for a gadget with temperature sensors and auto-defrosters.

Humidity Gauges

Hygrometers, sometimes called humidistats, are devices that measure the relative humidity in your space. Some have an extra feature that allows them to influence your dehumidifier.

Instead of just giving you an accurate reading, it will take corrective measures. These humidistats can turn on the dehumidifier when the rooms gets too moist, and turn it off once it achieves optimal humidity. It saves you the hassle of manually programing your device.

Filter Maintenance

Dehumidifiers work by sucking moist air into themselves and drying it out before releasing it back into the room. This air has other components besides water.

JHS Dehumidifier 

Some of these ‘ingredients’ are harmful, so get a humidifier that has several filtration membranes. They’ll partially cleanse the air before returning it into circulation. If your filter can be washed, it reduces the cost of repair and replacement, so check that your filter can be cleaned without too much drama.

Tank Capacity

In humidifiers, the water tank decides how long the device can run before a refill. With humidifiers, all the collected moisture goes into a sump that can be emptied later. The bigger the tank, the longer it runs. But you have to balance capacity against weight, price, and other factors.

For example, side drainage can be handy. It lets you link a pipe to your tank, guiding water towards a sink, cistern, or potted plant. That way, you don’t have to empty it manually.

Review of the Most Energy Efficient Dehumidifiers

There are other elements that come into play when you’re picking humidifiers. The size of your room, for instance, and the amount of moisture you’re dealing with. We’ve considered all these, and put together a list of our preferences. Each one has its own strengths and flaws, so let’s take a deeper look at our top contenders.

Why is it Better to Invest in an Energy Efficient Dehumidifier?

Dehumidifiers work by correcting excess moisture in your home or office. Without one, your space can get mouldy and damp. You painted surfaces could blister and peel, pipes could leak from condensation, wood could warp, electronics could fry, and allergies could get more aggravated. Too much humidity has also been associated with asthma. So you definitely need a humidifier, but what’s so special about energy efficient models? What’s their actual benefit?

Noise Control

In bikes, cars, and other automotives, power announces itself. Higher horsepower means louder engines. Dehumidifiers and other HVAC devices are similar.

The more power it takes to run your device, the more noise it will emit. There are other factors, like the technique used to lower moisture (e.g. suction, heat, vibration). Energy-efficient devices are generally quieter and safer.

Improved Hygiene

If your space is consistently humid, you’ll be uncomfortable. You’ll be nagged by that persistent damp smell, your skin may feel clammy, your hair will be a limp bedraggled mess, and you’ll have to spend a lot on professional upholsterers and carpet cleaners.  

JHS Dehumidifier

A good dehumidifier lowers routine household cleaning costs. It can also minimize pricey refurbishments to repair your foundations, walls, floors, door frames, and other areas with moisture damage.

Health Concerns

Our respiratory passages are sensitive to humidity. When the air is too dry, our nasal lining and throat cells can become irritated, causing dry coughs and nosebleeds.

At the other extreme, excessively moist air can encourage bacteria, mould spores, and germs to thrive, causing infections and triggering asthma. A dehumidifier (especially one paired with an air purifier) can lower your medical bills. It makes your air fresher and your residents happier.

Environmental Compliance

Some of us are really concerned with greenhouse gases and climate change. Certain countries are politically behind it, signing the Paris Climate Accord and actively switching to renewable energy.

While the US has pulled out of the deal, you may still want to do your individual part to conserve our surroundings. Using an Energy Star rated dehumidifier means you’re consuming between 10% and 20% less power than your friends and neighbors.

What Size Dehumidifier for Energy Efficiency?

Dehumidifiers come in different sizes. Which one you choose is determined by how big the room is and its relative humidity levels. According to the Department of Energy, dehumidifiers are sized as follows:

30-pint Dehumidifiers

A 30-pint dehumidifier can remove 30 pints of moisture per day. These devices can efficiently serve areas up to 3,000 square feet with relative humidity between 50% and 60%.

50-pint Dehumidifiers

50-pint dehumidifiers are suitable for mid-sized rooms with extremely humid conditions. They can collect up to 50 pints of moisture per day. These dehumidifiers can efficiently serve 3,000-square foot areas with relative humidity levels higher than 85%.

70-pint Dehumidifiers

70-pint dehumidifiers are considered the largest for domestic use. They work well for areas up to 3,000 square feet with relative humidity more than 85%.

You may be wondering just how much a dehumidifier will raise your electric bill. Here is a calculator to help you:

Aspects to Consider Before Buying an Energy-efficient Dehumidifier

There are several considerations you should make before buying a dehumidifier. These factors affect the type and size of the device you must buy. They include:

Room Size

For smaller residential areas, 30-pint dehumidifiers, are the most efficient. Larger dehumidifiers can be used in larger areas.

Relative Humidity Levels

For humid and wet rooms, you need large dehumidifiers for efficiency. In areas where the moisture collection rate is high, you need self-draining dehumidifiers to avoid regularly emptying the bucket.

The Number of People in the Room

A crowded room equates to a higher amount of moisture being released into the air. Therefore, you need larger dehumidifiers for areas with many people.

Cost of the Dehumidifier

The dehumidifier you buy should be affordable. You should meet the maintenance costs without straining your finances. If you can’t afford one that suits your needs, you can consider hiring.

Tips on Increasing Energy Efficiency in Dehumidifiers

To increase your dehumidifier’s energy efficiency, here are some tips you should consider:

Use the Dehumidifier for the Right Room Size as Specified

You spend more energy and time when you use smaller dehumidifiers for large rooms. Using big dehumidifiers for smaller areas is also inefficient, as they consume more energy than required.

Turn Off the Dehumidifier When Not in Use

Once you achieve the required humidity levels, turn off the dehumidifier to save energy. Some devices have automatic on/off systems that help conserve energy. However, you might need to key in certain settings to achieve this mode.

Use Portable Dehumidifiers

Use a portable dehumidifier to remove excess moisture from several rooms. You can dehumidify them one after another based on priority.

JHS Dehumidifier

Keep Doors and Windows Closed When Necessary

The location of your windows and doors determines how much one-way humidity enters your house. If you have a running humidifier, keep them locked to minimize the amount of incoming moisture.

Conclusion

Danby’s 70 Pint Dehumidifier may look dull and uninspiring, but it has a leg-up over all the other humidifiers on our list. It uses minimal energy and has maximal drainage space. It retains its settings despite unplanned shut-offs, and it can be directly emptied using a standard sized hose.  It can run for 24 hours at a time, ensuring your home retains optimal relative humidity.

For all these reasons, the Danby dehumidifier remains our firm favorite. A lot of us view conservation as an abstract idea. But in the HVAC space, buying an energy efficient dehumidifier could save you hundreds of dollars in utility bills. It lowers your carbon footprint, and is good for your health as well. Devices that use minimal electricity have extended lifespans, because there’s less wear and tear, so you can go longer periods before replacement.
