The best dehumidifiers can be a serious problem-solver in homes that suffer from a build up of mold and the spores and bacteria that result from it. No matter how clean we keep our homes, these problems crop up for almost everyone at some point, and a good dehumidifier is one of the most effective ways of preventing it.

Dehumidifiers work by absorbing excess moisture from the air in a room and either collecting it in a removeable tank that needs to be emptied manually, or pumping it into a sink or outside via a hose.

Mold thrives in damp or wet environments, but keeping the levels at less than 60% goes a long way to keeping it from it developing in the first place. As a bonus, it can also help your clothes dry faster, as it absorbs the water from your laundry!

We've taken a look at some of the best dehumidifiers out there right now, helping you to choose the right one for your home. And if you're also looking to clean the air, take a look at our roundup of the best air purifiers.

How it performs

Able to remove up to 50 pints of moisture from the air every day, the TaoTronics dehumidifier is recommended for larger homes that experience a lot of humidity-related problems such as mold and condensation. It has a built-in sensor that helps keep the levels in the room at a comfortable 45-55% (or you can run it continuously if you prefer) and the auto timer means you won't accidently waste energy by forgetting to turn the machine off.

You can connect a hose to the dehumidifier to divert water either out of a window or into a sink, but you'll need to buy this separately. An auto pump drain hose comes with the machine.

Offering moisture removal at a rate of 35 pints/day across up to 2,000 sq ft of space, even your largest room is unlikely to be a match for it. Connect a drain hose to the machine for continuous use in problem areas, or wait for spacious water tank to fill up (of which you'll be notified).

The modern design of the LG PuriCare includes an easy-to-use LED display on top of the machine and a handle on the water tank for simpler emptying - though we should note that some reviewers of the product noted that taking the tank out and reinserting it without spills was quite tricky.

Because the dehumidifier is on wheels you can move it from room to room without any problem, and the 12-hour timer and auto-shut off for when the tank is full will help save energy.

Do dehumidifiers remove all of the moisture from a room?

Dehumidifiers are designed to keep moisture levels in the air at an optimal level, which doesn't mean 0%. It's recommended that humidity levels sit at around 45-60%, and many dehumidifiers allow you to keep levels between these numbers automatically.

If air is too dry, it can exacerbate problems such as snoring and allergies, as well as making it easier for germs and viruses to survive. This is one of the reasons why some households also have a humidifier, as these machines offer benefits from adding moisture into dry air throughout certain seasons.

Do dehumidifiers remove mold?

While too much moisture in the air of the home is a leading cause of irritants like mold, dehumidifiers unfortunately cannot tackle pre-existing built-up. We'd recommend removing any mold you find around the home, especially in traditionally damp areas such as the basement, utility room or bathroom, before putting your dehumidifier to work.

Once it's operating, however, you should see a marked decrease in future problems. Hurray!
