Things to Consider

While buying a dehumidifier is important, buying the right model for your needs is even more crucial as the wrong model could end up being totally useless in the long run. In order to help you choose the right unit, we have compiled the buying guide below to help untangle anything that might be tangling in your mind.

Tips on how to keep your bedroom environment healthy

Wash your bed sheets often

The feeling you get when you sleep on a fresh bed sheet is indescribable. Even though you can have an equally great rest without fresh sheets, oils, sweat, and bacteria accumulated on your skin are transferred onto the linens of the bed. This is one of the primary origins of acne, thus ensure you wash your bed sheets and pillowcases weekly, or at regular intervals. It’ll give you a more pleasurable sleeping experience, and even your skin will say thanks.

Unplug devices

When we’re exposed to any sort of light, the natural inclination of our body is to remain awake. Even vague, artificial lights produced by our phones, laptops, lamps, and other gadgets can thwart us from sleeping well. According to studies, the blue light generated by gadgets hinders the discharge of melatonin, which is a hormone connected to sleeping and nighttime in general. The simple solution is to unplug and turn your gadgets off before going to bed. In the event that you need to charge your computer or phone overnight, try to charge them in a room different from the one you’re sleeping in. If you live in a dormitory, try to plug your gadgets as far away as possible from your body.

Fresh air

If you can, try opening your window so that fresh air will come into your room. Fresh air is usually refreshing and calming, and can be comforting whilst you sleep, especially if it is raining outside. Enabling air flow into any bedroom will help to eliminate feelings of restlessness and confinement, which can affect attention and sleep quality. If there is no option to open the window, keep the door of your bedroom opened if you can.

Installing a dehumidifier

While every space requires a certain level of humidity, it becomes very uncomfortable when the humidity becomes excessive. If there is too much humidity in your bedroom, it can result in the growth of bacteria, mold, and fungi, which may consequently cause you to be having sleepless nights. If you’re facing something like this, it can be easily resolved with the help of a dehumidifier. A dehumidifier will help get rid of the moisture in your room and make your environment healthy.

Light up candles

dc5487170e2bcad511a461ec933826d1Candles naturally produce a relaxed, calm vibe wherever they are lit. The calmer an environment is, the calmer we get, and feelings of anxiety and stress reduce as a result. The relaxation that emanates from lighting candles raises the effects of attentiveness and helps reduce headaches, reduce muscle tension, heart rate, and blood pressure while promoting a good mood. All these are extremely helpful especially if you are preparing for a test or an important business meeting in the morning.

Tidy your bedroom

According to studies, clutter is extremely distracting, and whilst looking at excessively numerous things simultaneously, it overkills your optical cortex and hinders the ability of your brain to process data. Whether it is throwing away empty bottles and trash in your room, de-cluttering your desk, or just folding and hanging your clothes, everything works towards helping to improve your concentration.

Features to consider while choosing a dehumidifier for bedroom

61gCyPHJ3FL._SL1000_All bedroom dehumidifiers aren’t created equal, and if you’re looking for the right model for your needs, then you must know that there are different factors you must consider before opting for a particular one.

Noise level

Whether you are watching TV, reading, or sleeping, there are chances that you don’t like lots of noise around your bedroom. The usual noise levels for compressor-based dehumidifiers when standing three feet away usually range from around 55 to 67 decibels. The smaller units don’t have compressors, using something known as Peltier technology instead.

While these units produce a lot less noise, they don’t perform as efficiently as compressor-based models and come with smaller capacity, so you will need to choose whether a high humidification performance is worth sacrificing your peace for or vice-versa.

The quietest models on our list include the Pohl Schmitt MD500, the Pro Breeze Electric Mini Dehumidifier, and the Trustech Portable Mini Air Dehumidifier.

Coverage area

Another vital feature you need to look at before buying a bedroom unit is its coverage area. All you need to do is to determine the size of your bedroom and find a dehumidifier that is capable of effectively processing the volume of the air in that space so that you don’t wind up with an underperforming unit. Most manufacturers typically state their products’ coverage area. With its ability to cover about 270 square feet, the Afloia 2000ml Dehumidifier for Home is the model with the largest coverage area on our list.

Auto shut-off

The auto shut-off feature is one of the most essential features you need to look at when buying any modern dehumidifier, especially if you’re aiming at using it overnight. This feature works by automatically shutting off the machine when the tank reaches its full capacity, and thereby prevent water overflowing or in worse scenario, damage to the unit. Fortunately, every model on our list boasts this handy feature.

Water tank capacity

Pro-Breeze_Mini-Dehumidifier-5-minYou also need to consider the water tank capacity of the unit you intend to buy. While the average little unit will only hold about ten to fifteen ounces of water, you can also find models with bigger or small capacities. In the event that the humidity level in your bedroom is excessively high or you don’t want to be emptying the reservoir every couple of hours, then you might want to think about going for a unit with a larger capacity, such as the Afloia 2000ml Dehumidifier for Home.

Frost control

A refrigerant unit liquefies the air. However, in some scenarios, it may freeze the water vapors. The unit has a tendency to stop functioning efficiently or even completely in cases like that. Therefore, it is better to buy a machine which has a tendency of preventing water vapor from freezing.

Dimensions and weight

A bedroom dehumidifier’s dimensions and weight should be decided according to the level of the humidity and the size of the room. Portable units are usually compact and lightweight, which makes them convenient, easy to transport and set up in bedrooms with limited space. The dimensions and weight of a unit can also tell you its type, water tank capacity, and coverage area.

Compressor-based models are usually heavier and larger than other kinds thanks to the extra mechanical parts but castor wheels and handles enhance maneuverability. Besides, they have the ideal rate of moisture extraction in warm conditions or room temperature.


Something as crucial as a warranty should never be taken lightly when in search of the right unit for your needs. Without a warranty, you will have to shell out more cash on another machine, should anything go wrong. Our top pick, the Vremi 1,500 Sq. Ft. Dehumidifier, offers a very decent warranty.

Extra features

As usual, there’re some simple units that will offer you only the basic features, and there’re models with advanced specifications like timers, auto shut-off, built-in hygrometers, built-in humidistat, continuous drainage, full tank indicator, just to name a few. Obviously, you need to spend more money if you want an advanced device.


Like we’ve previously mentioned, just as excess moisture can cause discomfort, too low humidity can also feel uncomfortable resulting in cracked lips, dry skin, and nose irritation. Therefore, you are advised to choose a product with a humidistat which will allow you to set the humidity level you want the device to maintain. The Trustech Portable Mini Air Dehumidifier is an example of such model as it automatically shuts off when the humidity level reaches 45 percent.

The answer to this question is both yes and no. Eventually, whether you can allow your dehumidifier to work overnight or not will depend largely on the type of machine you have. Make sure it has an auto shut-off feature and quiet operation. It’s also advisable to empty the water tank before going to sleep.

All of the devices featured on this list can be used in small enclosed spaces such as bedrooms, kitchen, bathrooms, garages, and even RVs. Some of them can even be functional in larger spaces, just make sure you compare the coverage area of the machine against the size of the space in which you are intending to use it in first.

Our Verdict

Our top three bedroom dehumidifiers on the market are the Vremi 1,500 Sq. Ft. Dehumidifier, the Afloia 2000ml Dehumidifier for Home, and the Pro Breeze Electric Mini Dehumidifier.

The Vremi 1,500 Sq. Ft. Dehumidifier and the Afloia 200Ml Dehumidifier take up our first and second spots respectively, but not without a fierce battle between the two. The Vremi model eventually trumped, thanks to the many advanced features it comes with and its high dehumidification rate.

Our third spot is taken by the little but mighty Trustech Portable Mini Air Dehumidifier. Combining the functions of two machines – a humidifier and a purifier – this model is totally deserving of this spot.
