A hot and humid climate may be appealing to some, but it can, unfortunately, cause major issues within your home. In fact, too much humidity in the air can affect your personal health too! Common issues that arise from high humidity levels include damp, mold, and mildew, which can attack and damage wood, particularly windowsills that are prone to rotting. If you notice signs of any of these within your home, or you want to prevent this from occurring, you may want to consider a dehumidifier.
It's too simple to say that these devices are nothing but the opposite of humidifiers. Not only do dehumidifiers remove moisture from the air, but they also help reduce the number of allergens, bacteria, and dust mites that typically flourish in high humidity levels within your living space. They are also capable of eliminating those unpleasant odors associated with mold and mildew. By reducing these, your overall health can be improved and for those who suffer from allergies, a reduction in sinus issues will be prevalent. Dehumidifiers have also been credited with improving your sleep, and who doesn't want that?
So, how do dehumidifiers work? There are three types of dehumidifiers - compressor, thermo-electric, and desiccant, all of which reduce the overall humidity level and air quality in your home, but go about doing so in slightly different ways. The basics of any dehumidifier rather than a humidifier are that they filter the air to remove excess moisture by using a fan to draw the air in. Water that the dehumidifier removes from the air is absorbed or condensed and stored in a tank, that is either manually drained or continuously drained via a drain hose or built-in pump.
With so many models available, it can be hard to determine which dehumidifiers are best for your needs. This guide will analyze the best dehumidifiers that will remove moisture from your home, preventing the occurrence of mold, mildew, and damp that grows rampant in homes that retain large levels of moisture.

Features To Consider With Dehumidifiers
Filter
When you are considering the purchase of a dehumidifier, a key component is the air filter. Like air purifiers and smart air purifiers, they help ensure your air is free of dust, allergens, and bacteria that affect your health; they also protect the coils on some models, which helps prevent damage. Filters should be easy to remove so you can clean them at least once a month. A washable, mesh filter is best overall so that you don't have to spend more money purchasing new filters every time they require cleaning.
Humidistat
The best dehumidifiers include a humidistat that allows you to select your preferred humidity level in your home, and the dehumidifier will automatically maintain that level. Humidistats allow for ease of use, especially if your home is highly humid, you need not stress when a humidistat keeps moisture under control. If a dehumidifier does not include a humidistat, it is best to purchase a hygrometer to keep near the unit, but of course, comes at an additional cost.
Operational Temperatures
Dehumidifiers all have various temperatures at which they best operate. So, if your home is too cold, or if it too hot, the dehumidifier may not operate at its highest functionality, thereby reducing the overall amount of moisture they can remove from the air. For rooms such as basements that are typically much colder, it is crucial that you check the operating temperatures to ensure you won't damage the unit or render it inefficient in its performance.
Auto-Defrost
Compressor style dehumidifiers use coils to help condense the moisture it draws in, but water can freeze on these coils, resulting in damage and decreased performance (and not to mention, a mess!). Compressor style dehumidifiers should include an auto-defrost function to ensure that water does not freeze on the coils; this function will automatically turn off the unit if frost begins to form. Desiccant and thermo-electric style dehumidifiers do not use compressors, therefore the auto-defrost function is not something you need to consider when purchasing one of these models.
Room Size
If you need a dehumidifier to reduce moisture, nasty odors and to prevent mold or mildew, you need to consider room size. Sticking a tiny dehumidifier into a massive living area won't result in reducing relative humidity, and while it may pull some moisture from the air, it won't be doing so in an efficient manner. A good rule of thumb is that the larger or more damp the space in which you are wanting to use the dehumidifier, the larger the capacity of dehumidifier required. If you have a big space that you want to equip with quality home climate devices, don't forget to check out our list of air purifiers for large rooms.
Energy Efficiency
An Energy Star dehumidifier will help keep your electricity bills low, while efficiently removing pints of moisture per day. The last thing you will want to do is reduce humidity, but at the significant expense of your wallet, as your electricity bill can be tripled when using a unit that is not energy efficient, much like an air conditioner. It is common that the larger the dehumidifier, the more energy-efficient they tend to be. Keep your eye out for models that are Energy Star certified.
Pints Per Day
The more damp your space, the more pints per day of water you will want your dehumidifier to pull. The Association of Home Appliance Manufacturers provides guidance that can help you determine approximately how many pints of water per day that could potentially be removed, based on the size of the room. For example, a moderately damp room measuring about 2,500 sq. ft. could draw 26 pints per day, so a 30+ pint capacity dehumidifier would be suitable for you.
Water Tank Capacity
If you are able to set your dehumidifier up for continuous drainage, water tank capacity is not so relevant, however, if you will be manually draining, it can make all the difference! The smaller the tank capacity, the more often you will need to empty it. The majority of dehumidifiers have an auto shut-off function so that when it is full, it will stop running; while this is excellent so that the unit does not overrun, if you are out all day (or perhaps do not hear the alert), your dehumidifier will no longer be removing moisture from the air. For rooms that produce many pints of moisture per day, a small capacity water tank can be a pain.
Hose Outlet
For units that allow for continuous drainage and do not include a pump, the hose outlet will be essential in setting up gravity-fed drainage. Most dehumidifiers have a hose outlet that allow for you to connect an internally threaded garden hose, but you do need to check this, as it can vary from model to model. Some manufacturers, however, do provide a hose fit for purpose.
Noise Level
Most dehumidifiers are not louder than an air conditioner or similar appliance, but are not always necessarily the quietest things to have running, especially if you have one in your bedroom! To put it into a bit of perspective for comparison purposes, the average conversation is about 55dB, so any dehumidifiers running at this level or lower generally do not become bothersome to most people. Think about where you are placing your dehumidifier, as that will dictate the kind of noise level you will be happy with when running it.
Types Of Dehumidifiers
Compressor Dehumidifier
Compressor dehumidifiers use feature a compressor and pump, drawing in warm air that hits a cold surface which results in condensation, removing water from the air. They are generally more efficient, using less energy than other types. Compressor style dehumidifiers work well in warmer rooms as the inside of the unit needs to be cooler than the air outside of it to work well.
Thermo-Electric Dehumidifier
Thermo-electric dehumidifiers also referred to as a Peltier dehumidifier, converts energy into temperature. A fan pulls damp air into the unit - there is an element within the unit that is cool on one side and hot on the other (due to different voltages applied to either side) - which then passes through the cold section where it is then condensed into the water tank and dry air is exhausted. They are typically quiet to run, but generally have a small water tank capacity and remove moisture slowly from the air, so they are not suited to areas that have high humidity levels.
Desiccant Dehumidifier
Desiccant dehumidifiers do not use a compressor but have a wheel that functions like a sponge would absorb moisture from the air. Due to the lack of a compressor, most desiccant models are much quieter, making them popular for use in bedrooms and living areas. They can be used in colder rooms as there is no concern about coils freezing up, unlike dehumidifiers that use a compressor.
Dehumidifier FAQ
Q: Where should I place my dehumidifier?
When using a dehumidifier for the first time, you should place it into each room to ensure moisture is removed from your house, as opposed to just one room. Once you have allowed the dehumidifier to work its magic in each room, place it in a central location like a living area. Most dehumidifiers have air vents positioned on the back of the unit, so you need to keep a few inches between it and the wall. Of course, if you have purchased a dehumidifier for a specific room, then you simply need to set it up for use in your desired location.
Q: Should I leave my dehumidifier on all the time?
When you first get your dehumidifier, you may need to run constantly to reduce the relative humidity in a room. However, it is typically not necessary to run your dehumidifier 24/7 once humidity is under control. Some dehumidifiers have humidistat which will allow you to set your preferred humidity level; it will then run and maintain that level, without you needing to monitor it constantly.
Q: Should I run a fan with a dehumidifier?
You can run a fan with a dehumidifier, but it will not assist with removing moisture from the air. A fan can help with circulating air throughout a room and provides ventilation. Running a fan can also help make rooms feel cooler, which can help reduce the effects of the heat produced by some dehumidifiers.
Q: Do dehumidifiers use a lot of electricity?
It all depends on the capacity of the dehumidifier that you have purchased, as well as the type! While larger capacity units require more electricity to run, they are usually much more energy efficient compared to their smaller capacity counterparts. Compressor style dehumidifiers typically use less electricity; while larger compressor units will draw more electricity, they run quickly, so the compressor is not constantly running, thereby making them energy efficient.
Q: Can a dehumidifier dehydrate you?
No! A dehumidifier cannot dehydrate you - it can only pull moisture from the air. If you are using a dehumidifier in your bedroom and notice that you feel dehydrated, it could be that humidity levels are high or that you have not had enough water. It is common, however, to feel dehydrated after a long night's sleep.
Q: Can a dehumidifier help prevent mould and mildew?
Yes! Mold and mildew love damp environments and grow rampantly in them, which is a result of high moisture levels in the air. A dehumidifiers main function is to remove moisture from the air, thereby drying spaces out and preventing mold and mildew from growing on your patio. Air filters on most models are also great at collecting dust, bacteria, and allergens which further reduce the chances of mold and mildew appearing in your home, also improving your health and helping those that suffer from allergies. If you are concerned about health threats caused by air quality, you might consider devices like carbon monoxide detectors too.
