How to choose the best dehumidifier for you
There are a huge range of dehumidifiers on the market. Before choosing your favorite, here are a few factors you should consider:
In 2019, the U.S. Department of Energy instituted new dehumidifier testing standards(opens in new tab). Nowadays, dehumidifiers are assessed at lower temperatures to better simulate being placed in a real-life environment, such as the basement.
As a consequence, the biggest dehumidifiers, which originally offered 70-pint capacities, have now been reduced to capacities of 45-50 pints. This is because warm air can hold more water than cool air, so the dehumidifier will naturally absorb less in lower temperatures.
Medium-sized models, on the other hand, have been reduced from 50 pints to 30 pints capacities. Whereas small dehumidifiers have moved from 30 pints to roughly 20 pints.
Because of this recent change, many models are being discontinued and replaced with updated designs to suit the new procedure.
There are different types of dehumidifiers on the market. The most common type is a condensing dehumidifier, which pulls the absorbed air over refrigerated coils, which cools it enough the condense and separate the moisture.
Other types include desiccant dehumidifiers, which will use a water-absorbing material, and thermoelectric dehumidifiers, which operate with charged plates. Generally speaking, neither of these latter two types are as effective as condenser models, which is why we only recommend this type in our list.
Dehumidifiers generally come in three sizes: large (45-50-pint capacity), medium (30-pint capacity) and small (20-22-pint capacity).
Under the old regulations, these sizes were 70, 50 and 30 pints, respectively, and you’ll see such numbers with three older models above.
Features to look out for
The capacity in pints relates to how much moisture the dehumidifier claims to absorb per day. The bigger the capacity, the larger and damper space it can handle.
Pint capacity shouldn¡¯t be confused with bucket size however. This specification indicates how much the internal bucket can actually hold before it will need to be emptied. The larger the bucket, the less often you will need to empty it.
On this list you will find passive and pump drainage types. Passive types let you passively drain the water through a hose, or alternatively you can manually carry and empty the bucket yourself. Whereas pump drainage types will automatically pump the water out. Pumps are preferred as the water doesn¡¯t need to rely on gravity alone to drain, so you can direct the hose into a sink or out of the window. However, these models do cost more than without.
Energy Star Certification
It¡¯s always useful to look out for Energy Star Certification as this guarantees savings in terms of energy and money.
With a humidity sensor, your dehumidifier will detect relevant changes in the atmosphere and can automatically switch on and, in some cases, set its power accordingly. Those without a sensor will just be manually controlled.
A frost sensor will detect the formation of ice on the condenser coils. The dehumidifier will then shut off the compressor to give the ice a chance to melt. If it continues to run with frost on the coils, this can damage the parts and make the appliance work much harder to absorb any moisture.
If the dehumidifier suddenly loses power, auto restart means it will automatically switch back on to its previous settings once power is restored.
Number of speeds
This relates to how many speeds the fan has on the dehumidifier. The more speeds there are, the better as it gives you greater control and means excess energy isn¡¯t wasted.
How we test dehumidifiers
Products experts and analysts at the LavaLove continuously survey the marketplace and manufacturers to identify the models that consumers nationwide are most likely to find in stores and online. From there, we identify models for testing across different size categories to cover every need and budget. Note: We only test condensing models, since they capture more moisture than desiccant models (which use a water-absorbing material) or thermoelectric dehumidifiers (which use an electric charge to “attract” humidity).
Hands-on testing begins in our Lab under controlled humidity and temperature conditions. The key performance-based test measures how much water each dehumidifier collects in a 48-hour time period. Our engineers also use a decibel meter to assess how loud each machine is when running on its highest fan speed.
Usability is another important part of our evaluation; it happens in the Lab, as well as in the homes of consumer testers, allowing us to test the dehumidifiers under real-world conditions. We look at such factors as portability, how intuitive the display and controls are and ease of cleaning, including how easy it is to wash the filter and empty the water reservoir. Finally, we evaluate each brand’s customer service by contacting their help lines with a pretend problem and seeing how quickly it is remedied by the representative.
How to clean a dehumidifier
When you consider that bacteria and mold is being sucked into your humidifier, it¡¯s no wonder that it needs an occasional clean. This isn¡¯t as difficult as you might think, simply follow these steps if none are given in your manual:
1. Unplug the humidifier from the wall. You don¡¯t want to risk an electric shock!
2. Remove the water reservoir bucket and tip out any residual water. Clean this with warm soapy water and a microfiber cloth.
3. While that¡¯s drying, wash the filters. The filters collect any impurities so it¡¯s essential that these get an occasional clean. You should have a main filter and potentially a much smaller bucket filter. If you¡¯re not sure where to find these you can refer to your manual. Both need to be washed in warm soapy water, rinsed and then left to dry.
4. If you notice a lot of dust inside your machine, you can also use a vacuum cleaner with a brush attachment to pick up any remaining fluff.
5. Lastly, give the outside a once over with a microfiber cloth for finishing touches.
Pros And Cons Of Using a Dehumidifier
The following are a list of pros and cons of using a dehumidifier¡ªafter reading these, you should be able to have a more concise idea as to whether or not using one will really benefit the health of your home and your personal health.
Dust Mites, mold, mildew, and certain allergens cannot thrive in a dry climate; therefore, taking the humidity out of the air will help in lessening these problems.
Running a dehumidifier will help reduce dust in the air.
If your home (or any room specifically) has a musty or mildew-like smell, a dehumidifier can get rid of that odor, as those are caused by dampness.
Having a dehumidifier run frequently will ensure that mold spores will not grow on your furniture, clothing, bedding, etc.
Certain small insects are attracted to moisture, so having a dehumidifier will deter those little pests.
If you, your family members, or even your pets are prone to allergic reactions to moisture, mildew, or mold, keeping a dehumidifier running will help keep everyone happy and healthy.
Dehumidifier use will help your A/C run more efficiently, as it helps get all of the humidity out of the air and your A/C won¡¯t have to work double time.
Dehumidifiers can be loud and sometimes warm¡ªin the summer, this could be annoying.
Dehumidifiers are work¡ªyou must dump, clean, and refill the water-collection tank and also (some models) clean the air filter regularly. To prevent yourself from running down the hallway toward the bathroom, spilling dirty water, you can reduce your maintenance requirements by installing a drain hose that empties collected water into a floor-level drain.
Constantly running a dehumidifier will increase your energy bill.
A good humidifier (you need to get the size that is required for the room it is in) can be pricey. If you are actually wanting to reap the benefits of owning one, you need to splurge on a trusted and quality brand.
How to use a dehumidifier
Most dehumidifiers are very easy to use. Essentially, it¡¯s just a matter of setting the required moisture level and the unit will do the rest. All you will need to do is empty the water tank.
For a bathroom, you should position the dehumidifier just outside the bathroom door and ensure the door is left open so the unit can draw the moist air towards it. If you¡¯re drying clothes, just place the dehumidifier in the room, making sure the door and windows are all closed.
How much does a dehumidifier cost to run?
Dehumidifiers are generally cheap to run. Look for one which draws less than 330 Watts and you will never spend more than 12p per hour. It’s often much less on lower power settings.
What size dehumidifier do I need?
Domestic dehumidifiers can extract up to 25 litres of water per day, though some as little as 250ml. We have largely focused on 20l models since these are the most popular for domestic use. For larger spaces, damper environments or colder temperatures, choose something more powerful. (Or vice versa for smaller spaces.)
What works better than a dehumidifier?
If your home is above 50% humidity then a dehumidifier is needed. However, if humidity levels are below 30%, a humidifier is needed. To determine the humidity level in your home pick up a hygrometer for less than $20 at a home improvement store.
Is it bad to have a dehumidifier on all day?
An average unit in your space, if it was operating correctly, should extract the moisture to around 50 to 55% Relative Humidity. With this assumption, you can safely run your dehumidifier for about 12 hours a day.
Where is the best place to put dehumidifier?
The best place to put a dehumidifier is in the location closest to the source of the moisture. In multi-level homes, this means that dehumidifiers should most often be placed in basements or upstairs close to the stairs to your basement. This is because the basement is the most humid place in your home.
Does a dehumidifier use a lot of electricity?
The simple answer is yes, even though dehumidifier wattage or energy consumption of many models is low (Average being 483 watts), they stay on for at least 12 hours a day and in most cases, 24 hours. The average cost is about $1.95 daily, meaning it could cost up to (if not more than) $58.42 a month.
How do you know if you need a dehumidifier?
We suggest that the ideal is 50% relative humidity (Rh). If it’s above 60%, a dehumidifier is usually necessary. Try to avoid letting Rh drop to below 40% as this may make the air too dry, exacerbating respiratory symptoms.
- Set the humidity level. The optimal relative humidity level is between 30 and 50 percent, according to Energy Star (and 30 to 40 percent in colder areas during heating season). ...
- Pick the right spot. ...
- Close all windows and doors. ...
- Empty the tank regularly. ...
- Keep it clean.
If you're concerned about spending too much on your electricity bill, you can try calling your energy company and asking about the “best times.” Usually, the best times to run your unit, that will save you money, is between 10 pm and 7 am — this is when less people are consuming energy, which drives down the rates.What is the best setting for a dehumidifier in your home? ›
So what is the best humidity setting for a dehumidifier? According to Energy Star, the optimal level of relative humidity in your home should be between 30% and 50%. Anything below this range may cause extreme dryness in your home and levels above may promote bacteria growth.Where should a dehumidifier be placed for the best results? ›

How long will it take to get the moisture under control? As long as the dehumidifier you choose is large enough for the area it is working in, and there are no specific damp problems, then a dehumidifier will normally reduce the humidity to the chosen level within a few days to a week.How much should I run a dehumidifier a day? ›
Mini models can use as little as 22 watts, while high-volume dehumidifiers go up to around 500 watts. An example dehumidifier that can extract up to 20 litres a day, with a wattage of 480w would use 0.48 kWh, meaning that an hour's usage would cost just under 16p.Can you dehumidify too much? ›
Can you dehumidify too much? There is a chance of dehumidifying your home too much with a dehumidifier, especially if you are leaving your dehumidifier running for several hours on a timer unattended. Over-dehumidifying your home can lead to an increased chance of respiratory illnesses and dry and cracked skin.What is the best percentage to run a dehumidifier? ›
Many dehumidifiers are equipped with a humidistat, which measures and can set the relative humidity (rh) in a room. A 50 percent rh is recommended for summer, while in winter, the ideal rh can be as low as 30 percent. A whole-house dehumidifier may be needed if high humidity is a problem throughout your home.
Ideal humidity – and signs of trouble
Every home is different, but a level between 30 and 40 per cent humidity is typically ideal for keeping your home warm and comfortable in the winter, without leaving condensation on the windows. In the summer, that level can be higher, between 50 and 60 per cent.
Research from the Building Science Corporation found that humidity of 70% or higher adjacent to a surface can cause serious damage to the property. The Health and Safety Executive recommends that relative humidity indoors should be maintained at 40-70%, while other experts recommend that the range should be 30-60%.Will dehumidifier dry out damp walls? ›
Dehumidifiers work by removing moisture from the air. This can help to reduce condensation on walls and prevent mould and mildew growth. However, dehumidifiers will not necessarily dry out damp walls. If your walls are damp, you may need to use a combination of a dehumidifier and a fan to help dry them out.How close should a dehumidifier be to your bed? ›
Specifically, we recommend that you keep your humidifier at a distance of around 3 feet from your bed – although there's no inherent harm in placing it closer, if you're restricted on room.When should you not use a dehumidifier? ›
Most dehumidifiers should not be operated in temperatures below 60° F, since the moisture removed from the indoor air can freeze when it condenses on the cooling coils, which can damage the unit.Why is my dehumidifier filling up every day? ›
If your dehumidifier's water basin is filling up too quickly, you probably have extra water in the air due to an issue like a cracked pipe, water leak or open crawl space. If you're hardly getting any water in the basin, you may need to simply turn the control to a drier setting.Should a dehumidifier fill up every day? ›
The water volume will vary depending on the humidity level and the capacity of the collection tank. On average, a home dehumidifier collects five gallons of water per day. When a dehumidifier fills up quickly, you may have excess humidity in your home or an issue with the dehumidifier itself.Should I turn off my dehumidifier in the winter? ›
If the temperature or humidity drops below the ideal level, you will want to turn the dehumidifier off. You never want the coils or water to freeze because it can cause lasting damage to the device.Do dehumidifiers stop mold? ›
Mould will easily grow and spread if the right conditions are present. So, dehumidifiers don't kill mould, but they can help to prevent it from growing inside your home by reducing humidity. However, the best way to deal with it is to get rid of its source.Do dehumidifiers use a lot of electricity? ›
The simple answer is yes, even though dehumidifier wattage or energy consumption of many models is low (Average being 483 watts), they stay on for at least 12 hours a day and in most cases, 24 hours. The average cost is about $1.95 daily, meaning it could cost up to (if not more than) $58.42 a month.
A dehumidifier and an air conditioner can be used simultaneously. You should use a dehumidifier with your air conditioner when your air conditioner by itself cannot adequately keep the humidity levels at a comfortable level.How much water should a dehumidifier take out of a room? ›

Warm air can possess more water vapor (moisture) than cold air, so with the same amount of absolute/specific humidity, air will have a HIGHER relative humidity if the air is cooler, and a LOWER relative humidity if the air is warmer.Can I sit in the same room as a dehumidifier? ›
Yes it is perfectly safe to sleep in the same room as a dehumidifier. If you are particularly interested in a dehumidifier for the bedroom the noise level will be particularly important to you.
Ordinarily, a dehumidifier will not operate satisfactorily at temperatures below 41 degrees Fahrenheit or under extremely low humidity conditions. At temperatures below 41 degrees the evaporator coils may freeze. This could make it necessary to defrost the coils as often as once per hour.Should you use a dehumidifier in hot weather? ›
Using a dehumidifier in summer
To help keep your home environment as comfortable as possible throughout summer, running a dehumidifier is an ideal option to reduce the level of moisture in the air.
Ideal in-home humidity levels should hover around 45%.
Anything under 30% is too dry, and over 50% is too high.
The best relative humidity for sleeping and other indoor activities has been debated. According to the Environmental Protection Agency, the best indoor relative humidity falls between 30% and 50%, and it should never exceed 60%. Other studies suggest 40% to 60% is a better range.Is 60% humidity too high for my house? ›
When the indoor humidity level is below 30 percent, the air is too dry, which can harm both a home's structural integrity and the homeowners' health. Conversely, when the level is above 60 percent, the air is too wet, which is also harmful to both the home and the homeowners.Will a dehumidifier help with mold on walls? ›
If the humidity in a room increases, mold will start growing in patches on walls, clothes, and more. So, to answer your question, dehumidifiers do NOT kill mold, but they do prevent it by reducing humidity. If you have a mold problem in your home, don't wait. Mold spreads as long as it has a water source.Is DampRid good for humidity? ›
Does DampRid work? Yes. CHOICE household products expert Chris Barnes says, "We put a DampRid container in a sealed test chamber about the size of a closet with 80% humidity and a fan for air movement. Within three days, DampRid reduced humidity to 43% and collected almost half a cup of water."Does a dehumidifier stop damp smell? ›
There's a musty smell in your home
When you walk into your home, you want it to smell clean and fresh. Moisture in the air tends to hold and trap odor, Bautista says. A dehumidifier will dry out the air and take away this moldy scent.
Easterly-facing walls get less sunlight, so they suffer most from condensation. Move your dehumidifier between rooms with easterly-facing walls to fully protect your house from damp and mould.Should a humidifier be on the floor or table? ›
The higher up off the floor the humidifier is placed the better. It produces a mist that has to get mixed with the air. When the humidifier is placed on the floor, the mist has no chance to get mixed with the air and it causes wet floors. Try to put it on a nightstand or a table.
However, these machines are designed to work in a small area such as a single room. They are too small in capacity and size to efficiently dehumidify larger areas and, because you should keep the room closed off, a dehumidifier in the basement will have little effect on the upstairs.Where not to put a dehumidifier? ›
You want to place your machine in an area where there is good air circulation so the unit can efficiently work. We do not recommend placing a dehumidifier directly against a wall or piece of furniture. Instead, put it at least six inches away from these vent-blocking surfaces.Where is the best place to put dehumidifier? ›
The best place to put a dehumidifier is in the location closest to the source of the moisture. In multi-level homes, this means that dehumidifiers should most often be placed in basements or upstairs close to the stairs to your basement. This is because the basement is the most humid place in your home.What is a healthy humidity level? ›
What is healthy humidity? Most people find that a relative humidity between 30 to 60 percent is the most comfortable, with indoor humidity ideally between 30 to 50 percent.Will using a dehumidifier help lower or raise my cooling costs? ›
A dehumidifier will start to immediately reduce your utility bills once it comes on. Because your home will feel cooler with lower levels of moisture in the air, you will not need to run the air conditioner as often.Is it more efficient to run a dehumidifier on high or low? ›
Running a dehumidifier at a low setting is generally more energy-efficient than running it on a high setting; the medium setting strikes a good balance between energy efficiency and dehumidification rate.How long does it take a dehumidifier to reduce humidity? ›
How long will it take to get the moisture under control? As long as the dehumidifier you choose is large enough for the area it is working in, and there are no specific damp problems, then a dehumidifier will normally reduce the humidity to the chosen level within a few days to a week.Does dehumidifier make AC run more? ›
Reduced Energy Costs
It's true! A dehumidifier helps your cooling system work more efficiently day-after-day. By removing excess moisture from the air, your air conditioner isn't required to work harder to maintain ideal temperatures in your home.
If there are no cold-condensing surfaces and the relative humidity (RH) is maintained below 60 percent indoors, there will not be enough water in those materials for mold to grow. However, if the RH stays above 70 percent indoors for extended periods of time, mold will almost certainly grow.
Reduce Mold and Mildew
A dehumidifier is designed to reduce the moisture level in the air by extracting the excess water. By doing so, dehumidifiers can help prevent the growth of mold and mildew and improves the indoor air quality of your space.
Most dehumidifiers will remove between 30 and 70 pints of water per day. It's probable that a newly installed dehumidifier will run constantly, especially in excessively humid weather conditions.
