Best Dehumidifier for Bedroom

Are you worried about the constant dampness present in your bedroom? Your concern is justified since exposure to moisture buildup can have lasting health implications, especially among children.

Thus, it would be best to consider buying a bedroom dehumidifier for your family’s safety. These are air-conditioning machines that reduce excess moisture from the air.

But buying a dehumidifier isn’t enough. You need to buy the best and most effective one. So it’s worth asking if you should buy a desiccant or a compressor dehumidifier. What about the size? The pint capacity?

That’s what I’ll explain in this article. Towards the end, I list the 6 best dehumidifiers best suited for bedrooms. 

Is It Good to Sleep With a Dehumidifier?

Safety is above everything else. Therefore, before purchasing a dehumidifier, you should know if sleeping with a dehumidifier is safe. Can you have it turned on for the duration of the night?

Generally, it’s good to sleep with a dehumidifier if your bedroom has excessive moisture. This excess water content in the air can interfere with your sleep in multiple ways. More specifically, they can disrupt your comfort and breathing and expose you to allergens.

The body’s water will find it harder to evaporate with a high moisture level. As you might know, evaporation helps in regulating body temperature. Thus, you’ll sweat in the middle of the night and eventually wake up. So leaving the dehumidifier on for the night is safe.

But on the other hand, you need to ensure that the humidity level isn’t too low. Sleeping in a dry environment can cause dryness and inflammation in nasal passages.

It would be best to always aim for a humidity level of 30% to 50% while you sleep. If it’s more than 50%, use a dehumidifier. Conversely, if it’s less than 30%, install a humidifier.

Best Dehumidifier For Bedroom Summary

What are The Different Types of Dehumidifiers That Can be Used in a Bedroom?

There are three types of dehumidifiers available in the marketplace. You can use any of the three. But one type is considered better for the bedroom than others. And that is a desiccant dehumidifier.

The three types of dehumidifiers are:

  • Refrigerant (or compressor) dehumidifier – The most common type of dehumidifier works along the principles of a refrigerator or AC. They have coils that condense moist air to remove excess humidity. After subtracting the extra moisture, the warm, dry air is added back to the room.
  • Desiccant dehumidifier – The second type of dehumidifier uses a humidity-absorbing material instead of coils. The material is known as desiccant and silica gel or bentonite clay. The liquid particles get adsorbed by the desiccant, and that’s how moisture is removed in this case.
  • Thermoelectric dehumidifier – The final type of dehumidifiers are less common because of their poor coefficient of performance. Thermoelectric units employ a Peltier heat pump to capture the humid air. At the current stage, the technology is not yet efficient.

Of all the three types, desiccant dehumidifiers are better for bedrooms because they’re super quiet. They do not produce as much noise as compressor dehumidifiers. Desiccant units are also better in colder regions because they can operate at a lower temperature (below 15°C), but compressors can’t.

Besides the above three types of dehumidifiers, there’s another type you need to know. And these are whole-home dehumidifiers. These are compressor dehumidifiers but designed for the entire home.

Thus, they’re more powerful and can regulate humidity in any room, not just the bedroom. On the flip side, they tend to be expensive.

What Features do I Need to Consider for a Bedroom Dehumidifier?

Not all dehumidifiers will have the same set of features. Therefore, you must ensure the unit has the necessary functionalities when purchasing one for your bedroom.

As a minimum, you should look at the following features in a bedroom dehumidifier:

  • Pint capacity

Concerning dehumidifiers, pint capacity refers to the amount of moisture the machine will remove from the air in a day. The bigger the pint capacity, the more excess humidity it can reduce.

Pint capacity in dehumidifiers can range from 5 pints to over 150 pints. For commercial dehumidifiers, the capacity can exceed 300 pints in some cases. If a dehumidifier is rated 15 pints, it will capture 15 pints (7 liters) of moisture in 24 hours.

Of course, this depends on several factors like temperature and the machine’s power settings.

Along with pint capacity, you should also check bucket capacity. This is the maximum amount of water the bucket can hold. Ideally, it should be equal to the pint capacity. But there are machines with smaller buckets.

  • Humidistat

A humidistat is an important feature that bedroom dehumidifiers should have. It is a device that helps maintain a humidity level. So if you set the humidistat to 40% to 50%, the machine will change its settings automatically to maintain this range.

Although used interchangeably, a humidistat is different from a hygrometer. The latter only reads the humidity level in a room, but a humidistat goes beyond that. A dehumidifier with a humidistat will cost more. But it’s well worth it, especially in bedrooms where comfort is the priority.

  • Manual or digital controls?

A dehumidifier can either have manual or digital controls. Opting for digital dehumidifiers with LCD screens is recommended for simplicity.

In the case of a digital machine, you can set explicit ranges like 40% to 50% humidity. Along with that, the screen displays related parameters. Manual units feature knobs and switches to control the machine. This is not only non-intuitive but also prone to errors.

  • Auto turn-off

The auto turn-off feature enables the dehumidifiers to shut operations when the bucket gets full, or the desired humidity level is reached.

This feature is beneficial for dehumidifiers with smaller buckets. You don’t have to wake up every few hours to change the bucket once it’s full.

Most modern dehumidifiers have this feature, but it’s worth confirming before buying.

  • Air filters

Dehumidifiers with air filters can make a difference in the bedroom. These are intended to cleanse the air as it passes through the dehumidifier. So along with removing excess moisture, you also get clean air.

Air filters are more important for people with asthma or allergies. Thus, keep an eye out for the same when prospecting for dehumidifiers.

  • Portability

Lastly, it is worth looking at the portability of a dehumidifier. Some are simple handheld devices you can carry from one room to another. Other models are much bulkier, with sizes equivalent to small suitcases.

The latter type of dehumidifier must have handles and caster wheels. These make them easier to transfer to any corner of the bedroom.

There are a host of other features that you can consider, but they’re all add-ons. If the dehumidifier has the features above, it’s likely the one you should invest in.

What Size Dehumidifier do I Need for my Bedroom?

Another crucial factor to consider when buying a bedroom dehumidifier is the size of the bedroom. The bedroom size, in turn, depends on your bedroom type.

Once you have determined the bedroom size, here’s a chart to help you select the right dehumidifier:

  Bedroom size in square foot (→)
Bedroom Humidity Level (↓) 100 sq ft. 200 sq ft. 300 sq ft. 400 sq ft.
50-60% 5-10 pints 10-15 pints 15-20 pint 20 pints and above
60-70% 5-10 pints 10-15 pints 15-20 pint 20 pints and above
70-80% 10-15 pints 15-20 pints 20-25 pint 25 pints and above
80-90% 15 pints and above 15 pints and above 20 pints and above 30 pints and above

You can always invest in a more powerful dehumidifier with 50-pint capacity and have it operate at a low range. This would allow you to use the machine in other bigger rooms if necessary.

  • Is a dehumidifier noisy?

Dehumidifiers aren’t noisy when compared to air conditioners or HVAC units. Most dehumidifiers operate between 40 to 60 dB noise level. But desiccant dehumidifiers are even quieter and can operate at below 40 dB. 

  • How long does a dehumidifier take to dry a bedroom?

It depends greatly on the room size, the dehumidifier air flow capacity, environmental conditions, and other factors. But generally takes about 2-3 days to dry a bedroom completely.

  • Do dehumidifiers help with mold?

Yes, dehumidifiers do help with mold. Reducing moisture in a room inhibits mold growth, which relies on water.
