There are truckloads of products on the market — we’ve compiled an in-depth buying guide and a list of the best bedroom dehumidifier reviews so you can make the right buying decision for you.

Let’s take it away…

Why Use a Bedroom Dehumidifier?

A dehumidifier is a machine that draws in excess moisture from the air.

Too much humidity and moisture in your bedroom can lead to problems like mildew, mold, viruses, dust mites and even respiratory problems — definitely not what you want when you need a good night’s sleep.

If you live in a hot and humid climate — or just a humid one at that — a bedroom dehumidifier is a must-buy.

Experts suggest that bedrooms require around 30-50% humidity all year round to be considered quality air for sleeping. Generally, we expect high humidity in Spring and Summer with much lower levels during Winter and Fall (you might want to look into a humidifier unit for those months!).

The best bedroom dehumidifier will control the humidity levels and maintain them at the ideal level, while also reducing irritation to your respiratory system and skin, helping you to breathe easier and be more comfortable in the bedroom.

You don’t even have to worry about noise, as they run quietly in the background.

If you use an air-conditioning system for your home, a dehumidifier should also help to lower your energy costs. Air conditioners have to work hard on their own to cool the air and remove moisture but your unit will last longer and run more efficiently with a little help from a dehumidifier.

It also means you’ll save money on air conditioner system repairs and replacements in the long run. Ideal!

How Do Dehumidifiers Work?

If you’re anything like us, you’ll be curious to know the mechanism of how a dehumidifier actually gets to work.

It’s pretty simple:

  1. A fan within the dehumidifier brings the humid air inside the unit
  2. The air passes over cold pipes within the unit that cools the air and withdraws the moisture
  3. The caught moisture attaches to the cold pipes and drips down into the dehumidifier’s bucket
  4. The original air passes over different, warmer pipes in order to go back to its original temperature
  5. Another fan blows the dehumidified air back out into your bedroom, usually through a clear air filter

You’ll need to periodically empty the bucket at the bottom of the dehumidifier as it fills up with the excess moisture that it draws from the air.

If you’re more of a visual learner, take a look at this video about the ins and outs of how dehumidifiers work:

What Makes the Best Bedroom Dehumidifer?

There are a few features to look out for to help you spot a good dehumidifier for your needs and home.

Firstly, you need to make sure that it’s big enough. We don’t necessarily mean its physical size, but rather its capacity.

Dehumidifiers measure their capacity in the number of pints of air they’re able to process per day. The bigger your bedroom, the bigger capacity you’ll need — whereas smaller bedrooms can get away with smaller machines.

For even greater efficiency, look for bedroom dehumidifiers with an in-built water pump which will ensure your product functions at maximum capacity for as long as it’s running.

There are tiny dehumidifiers available on the market for the smallest rooms: they’re cheap, small enough to fit on your bedside table and quiet as a whisper.

At the other end of the spectrum, you’ve got large dehumidifier units that are able to handle the largest of rooms. Of course, you’ll need space to store them and they might be a little louder than the tiny bedside units, but hopefully the size of the room should help you out with that!

Looking at Amazon reviews — or whatever marketplace you choose to buy from — to see what previous buyers have said about the product you’ve got your eye on. This is especially important when it comes to the noise factor of the dehumidifier. If it’s going to be noisier than your air-conditioning, you may want to think twice. There’s no point in improving your bedroom’s air quality if it’s going to be too noisy to sleep!

Other things to look out for are maintenance requirements and ease of use.

Most modern dehumidifiers for the bedroom have an LED display and a few intuitive buttons to help you get the machine up and running in minutes. If the dehumidifier requires programming, make sure that you’re not buying one that’s too difficult to set up.

A good rule of thumb when buying these industrial products is to buy from big name brands with plenty of heritage and experience behind them. You can usually rely on these dehumidifiers to get the job done and be as durable as can be.
