Best Dehumidifier for Bedroom

Best Dehumidifier For Bedroom Reviews 2019

Your home is your castle, but your bedroom is your comfort. It is the place where you rest, dream, and take solitude from the pressures of the world. So when your bedroom is not comfortable due to excess humidity, it can be very aggravating. Feeling swollen and overheated on top of smelling damp mildew is not pleasant. Luckily, a small or midsized dehumidifier may be all it takes to bust through that cloud of moisture and return your space to the relaxing haven you need. We’ve got plenty of information on the best dehumidifier for bedroom use, so read on!

Experts say that you will be most comfortable in a bedroom that maintains a 30-50% humidity level year round. That level is ideal to stop the growth of mold and mildew, thereby improving air quality and reducing incidence of respiratory issues. You’ll be able to both breathe better and feel better.

Air conditioning systems can help to control humidity, but they aren’t made specifically for that purpose, and will struggle to even cool the space in high humidity conditions. A dehumidifier works very well in tandem with an air conditioner, making it easier for both machines to do their jobs optimally.

Because you are interested in reducing humidity in your bedroom, we will assume that you would like a unit that is quiet. Unobtrusive operation noise is the first requirement for the dehumidifiers on our list. However, you will always get quieter operation from small electric units without air compressors and powerless desiccant dehumidifiers that use silica gel beads to absorb moisture.

The trade-off is that these dehumidifiers don’t have the same capacity (daily amount of moisture that can be drawn from the air) that larger electric models do. These work via compressor and will make more noise than one without. But don’t worry if you need the greater capacity of a compressor-equipped model, we have a selection of the quietest of those, as well.

Following is a detailed description of available features to look for and thorough dehumidifier reviews for five of the best reviewed models for the bedroom.

There are a few different ways that dehumidifiers work, but for our purposes, we will be looking at electric models both with and without internal air compressors. This should give you the balance of capacity and quietness that you need for a bedroom environment.

Dehumidifiers like this work by using a fan to pull air across refrigerated coils. That cooling action causes moisture to be pulled from the air, at which point it drips into a collection tank. Beyond the basic operation, there are a number of other features that can help you choose the best dehumidifier for you.

User-Friendly Controls

Many dehumidifiers come with LED display screens that make it easy to turn the unit on and off, set a timer, see the room’s current humidity level, know when the tank is full, and more.  The smaller the unit, the less likely you are to have many bells and whistles, but no matter how basic, you’ll want a unit that is easy to operate.

Auto Restart

Auto restart is a feature that turns the dehumidifier back on after a power outage. This can be very helpful if your humidifier is in a place that you don’t see that often, such as a crawl space or even a vacation home. It’s also good if the outage happens while you are away at work, so you don’t come home to a muggy mess.

Hose Drainage Connection

Most of the smaller dehumidifiers have a collection tank to hold water, and they need to be emptied pretty frequently. Other models come with a hose connection that allows you to divert water somewhere else. Though you probably don’t have a sink or floor drain in your bedroom, it is also possible to route the hose out a window, or else into a larger container than the included tank. That can help make emptying the water less of a hassle.


If your dehumidifier has a timer function, you’ll be able to set it to run exactly when you want it to. This is a good way to save electricity by operating your dehumidifier only during off-peak hours when electricity is less expensive. It may also help to keep it off when you won’t be home and don’t care if the room is humid.

Frost Sensor

We usually think of humidity as a warm weather problem, but there is also a type of cold dampness that gets right into your joints. You may still be using a dehumidifier in winter. Unfortunately, many dehumidifiers don’t work very well in cooler temperatures because the coils become frosted over. A sensor that turns off the machine when this happens is useful because it won’t be able to pull moisture in this condition and you will just be wasting electricity.

Washable Air Filter

A bonus function of many dehumidifiers is that they purify the air. Moist air gets pulled through an air filter, trapping allergens and particulates. But when the air filter gets clogged, the unit has to work too hard to move air and will likely burn out the motor. If your air filter is washable, simply remove, rinse, let dry, and replace. If it’s not reusable, you’ll need to shell out for a replacement.

Easy-to-Empty Bucket or Tank

Water is heavy, so if you are concerned about carrying the full bucket, stick with a smaller model that gets emptied more often. It’s good to look for a collection tank with ergonomic handles for carrying, and a nice secure seat in the unit.

Other Factors to Guide Your Choice

Before you buy a dehumidifier for use in your bedroom, it is good to understand their benefits and limitations.

Understanding Capacity

Capacity refers to the amount of moisture that can be removed from the air over a 24 hour period. In general, the smaller the dehumidifier, the lesser the capacity. Capacity does not refer to the size of the water collection tank, but again, the smaller the unit, the less water it can hold. You’ll need to balance the amount of space you have to house a dehumidifier with the level of humidity in the room. You may need something a bit bigger to handle the moisture level, but many mid-size units come with casters that make them easy to roll from place to place.

Operating Noise

Whether you are sleeping, reading, or watching TV, you probably don’t like a lot of excess noise in your bedroom. Typical noise levels for dehumidifiers that have air compressors range from about 55 to 67 decibels when standing 3 feet away. The more compact dehumidifiers do not have compressors, instead utilizing something called peltier technology. These dehumidifiers make much less noise but don’t work quite as efficiently and have a lesser capacity, so you’ll have to decide whether a little noise is worth it to get the humidity level where you want it.

Buy New to Save Money

Because of new federal energy standards, older dehumidifiers are simply not as energy efficient as new ones. The overall cost of your dehumidifier depends a lot on the operating costs, which can be steep depending on how often you run it. We recommend that you skip the garage sale units and buy new to keep that electricity bill down. Reading the dehumidifier reviews available online for any model you consider can help you make sure you are buying an energy efficient option.

Product Reviews

Following is more detailed information about the dehumidifiers on our list.

  1   Ivation 13-Pint Small-Area Desiccant Dehumidifier Compact and Quiet - With Continuous Drain Hose for Smaller Spaces, Bathroom, Attic, Crawlspace and Closets - For Spaces Up To 270 Sq Ft, White

This Ivation model represents an excellent balance between quiet operation and a strong capacity. It call draw 13 pints of moisture a day in a space up to 270 square feet and can hold a half gallon of water before it needs to be emptied. Even better, it is equipped with a drainage hose so you may simply direct this out a window or into a bucket if you don’t want to mess with the collection tank.

The reason the Ivation can deliver strong capacity and low noise level in a compact size is the unique desiccant rotor. It functions as a hybrid of the standard electric model and the desiccant-only kind; while it still uses chilled coils, it doesn’t need a compressor.

This dehumidifier does give off some heat while it works, which is great in colder months (and may reduce your power bill) but could be unwanted in the midst of summer. However, that is a small trade-off when you consider the versatile performance. Functional in temperatures anywhere from 33°F to 104°F (1°C-40°C), the Ivation has an LED display with built in humidistat, multiple fan speeds, timer/sleep mode, and adjustable screen brightness. You can also change the position of the vent grille to assist with drying any clothes hanging nearby.

And finally, this unit offers an anti-tilt shutoff function that turns the unit off when it detects sudden movement. So you needn’t worry that accidentally kicking or elbowing it will cause an electrical disaster. The machine works quietly without a noisy compressor. The built-in humidistat allows adjustments in 5% increments, and you may also set the readout to either C° or °F, depending on preference.

  • Effective desiccant rotor
  • Large collection tank and continuous drainage option

  2   TOSOT 70 Pint Dehumidifier spaces up to 4500 sq. ft, Perfect Basements, Energy Star Certified, Portable Wheels, Reduce Mold Moisture

We’ve included this larger capacity model as a best dehumidifier for bedroom use in case you have a larger or open concept room. Most dehumidifiers work best in enclosed spaces, but that’s not always possible. Another good application for a higher capacity dehumidifier is in the most humid climates where a small compressor-free model will probably not suffice.

One of the nicest features of the TOSOT 70 pint dehumidifier is its quiet operation. It rarely breaks 52 decibels (50 decibels is about the level of normal conversation in a home). It is also Energy Star rated and doesn’t cost a ton to operate. This model comes with the option to use a continuous drain hose, but if you don’t, the bucket will need to be emptied frequently, about every 5 hours. It’s easy to do with the ergonomic carrying handle and spill-resistant baffles on the containment bucket, but may not be ideal for people who want to run their dehumidifiers while they are away at work all day.

The LED display screen allows you to set either a 2 or 4 hour sleep timer, as well as program the unit to come on after a certain time. Also view the current room humidity level and set your preferred target. The screen is minimalist in feel, so it won’t confuse you. Though this dehumidifier is bigger and heavier than others on our list, the caster wheels on the bottom allow it to float effortlessly across the floor should you need to relocate it.

  • Drain hose option

With a daily capacity of 300 ml and a tank that holds up to 700 ml, it is ideal for smaller or moderately humid rooms. The controls are basic, with one-press on/off capability and auto shut-off when the tank gets full. It is an easy little device to set and forget, at least until the tank needs to be emptied. It is an energy-saving, environmentally friendly model that is made from safe ABS plastic and won’t waste your electricity.

You get a 30 day money back guarantee with this product, plus a nice 24 month warranty. The manufacturer suggests that to get the most out of your unit, make sure that the air inlets on the front and outlets on the top are kept free of blockage. As long as you keep the air flowing freely, you’ll barely know this whisper quiet dehumidifier is on.

  4   Afloia Electric Home Dehumidifier, Portable Dehumidifier 700ml (24fl.oz) Capacity up to (215 sq ft) Quiet Room Small Dehumidifiers for Home Dorm Room Baby Room RV Crawl Space

This Afloia model is nothing fancy but it does what it is designed to do. It works almost silently at 35 dB, which makes it one of the quietest dehumidifier choices available. The unit is able to pull 300 ml of water per day and has a tank that holds 700 ml. It is best for smaller spaces up to 215 sq ft, but despite its small size, works in environments up to 90% humidity. Weighing in at less than 3 pounds, the Afloia designed to be portable.

The front-oriented water tank is easy to remove and empty, and the auto shut-off feature (plus LED indicator light) protects against spills. The unit is built to be energy conserving. It is not recommended that you run this dehumidifier in temperatures colder than 50ºF (10ºC), but it can keep on chugging in temps as blisteringly hot as 122 ºF (50ºC). Unless you live smack in the middle of the desert, we hope you don’t regularly endure weather like that!

Though this is a very basic machine without a lot of added features, users appreciate the difference it makes in their space and its near-silent operation. It’s also an easy unit to move around as you inhabit different rooms within the house.

  5   Arctic Aire ADR30B1G 30 Pint Dehumidifier

Arctic Aire has designed a 30 pint dehumidifier you can feel good about using. It uses environmentally friendly R410a refrigerant and is Energy Star rated, so the operating costs won’t break the bank. It is also comes with highly customizable controls. The electronic display lets you set your desired humidity level and toggle between two fan speeds. The washable air filter is easy to remove and clean, plus there is a continuous drainage option available as well.

Noise-wise, the Arctic Aire is louder than some of the compressor-free models, but still only puts out 52-53 decibels (about as loud as a refrigerator). What sets this unit above is the auto de-icer, which doesn’t just shut off the compressor when the coils get frozen, it actively works to keep the coils from freezing at all. That means no downtime when you really need your dehumidifier to be working.

This model dehumidifies competently in spaces up to 1,500 square feet and handles temperatures as low as 41ºF (5ºC). It is middle-of-the-road in terms of extra features, but is built to be very easy to use. Sturdy rolling casters make it easy to relocate as needed. A nice two year warranty means you can purchase the Arctic Aire with confidence.

How to Know if You Need a Dehumidifier

Every home contains a certain level of dust, allergens, and residue from cleaning chemicals. But when the home is too humid, these irritants become airborne and can negatively impact the health of the residents. Excess moisture also creates the perfect environment for nasty mold and mildew to grow. A dehumidifier can bring the air quality back to its ideal conditions for freshness, better breathing, and physical comfort.

Following are the signs that indicate your room is too humid.

1. Mold Growth

It’s not too difficult to spot mold growth if you’re looking for it, but it can often hide in sneaky areas such as dark corners and the back of cabinets. Check first in areas that get a lot of humidity on a regular basis, like the ceiling above your shower or the wall behind the toilet. Basements, storage areas, and garages are also often damp and allow mold to grow. If your geographical area is very humid, any room can play host to mold. If you find a smattering of dark spots, that’s mold. Unchecked mold growth spreads like fire and will often require replacement of affected walls.

2. Condensation

Condensation occurs naturally on your bathroom mirror when you shower and on the outside of a cold glass on a hot day. This is normal, and no big deal as long as that humidity doesn’t hang around too long. If you are seeing condensation regularly on the glass window panes in your home, that’s a sign that there is too much humidity throughout the day.

3. Water Run-Off

Due to bad construction or a steep grade to the surrounding landscape, homes can suffer from water issues whenever it rains. If you are spotting standing water in your basement or find that the walls get damp on a regular basis, a dehumidifier can help to prevent extensive damage. However, it is also crucial to identify the root cause of the dampness, because excess moisture over a long time causes walls to crumble, during which time they will also be breeding mold.

4. Musty Odors

You are no doubt familiar with the musty smell that indicates dampness. That smell is almost always a sign that something nasty is growing in the space. Usually this is due to environmental humidity, but it can also mean your windows aren’t sealed properly. A dehumidifier can help to get rid of that musty smell, but you’ll still want any mold to be carefully removed so that it can’t get a new toehold any time you forget to empty the dehumidifier.

5. Water Damage & Stains

Water stains are often the result of an overflow somewhere in the house, but they can also occur when too much moisture creeps in through unsealed cracks. There may also be a leaking pipe somewhere behind the wall. A good dehumidifier will reduce the humidity level of the room, but if you have a leak of any kind, the walls will stay chronically damp and allow mold to flourish. Get a professional to examine water stains as soon as you notice them.

6. Rotting Wood

Damp wood rots and attract pests like termites. If you see this in your home and can’t find a cause for it, there is probably too much moisture in the area. Run your dehumidifier to clear out the air, but don’t forget to replace any affected wood. In the absence of a broken pipe or other source of dripping water, a dehumidifier should maintain your new structure for many years. However, leave rotting wood and it will eventually affect the structural integrity of the entire home.

7. New allergies

Finally, if you are suddenly plagued by uncomfortable allergies or have trouble breathing, it could be related to the humidity level. Humidity over 50% allows airborne allergens such as dust mites and mold spores to develop at a rapid pace. Breathing them in can cause a whole host of allergy symptoms, including sore throat, coughing, runny nose, congestion, and sneezing. Running a dehumidifier will clean the air, keep the allergens at bay, and make you a lot more comfortable.

Final Note: Fix Existing Problems

Dehumidifiers do a great job of maintaining a comfortable humidity level in your bedroom, and can improve breathing, eliminate odors, and just generally keep you feeling better. However, even the best dehumidifier can’t stand up to water leaks from poorly constructed or malfunctioning home systems. Sometimes faulty seals in glass showers or where the toilet meets the floor can let water drip onto and through the floor, causing water stains on the ceilings below. Leaky pipes or cracked sealant around windows can also be an issue. These are things that must be addressed with professional maintenance in order to avoid catastrophic damage and let your dehumidifier do its job.

We hope that we have given you the information you need to choose the best dehumidifier for bedroom use. There are so many different sizes, capacities, and included features that at least one should really fit the bill for your space. Sweet dreams are ahead with any of the quiet, reliable models on our list.
