Best Dehumidifiers 2021

If the humidity in your home or car is exceeding, not only the walls and ceilings are prone to become damp and mold, but also you are likely to be unhealthy.

In some climatic zones, even the most well-ventilated houses might encounter similar issues, too.

But a single dehumidifier can be an effective solution!

Here we have compiled and reviewed the top 12 best dehumidifiers that have the highest-performance in specific cases. So, let’s read our guide carefully, and you will surely find out the most suitable choice for your own situations.

Here we go!

What To Consider When Buying A Dehumidifier

When it comes to moisture removing equipment, there is nothing called “one size fits all”. Thus, like most of the electronic household devices, dehumidifiers come in various shapes, sizes, styles, and functions.

As you research the market, you can find out that even dehumidifiers of the same size and type might deliver very different performances.

Consequently, there are a few things that you need to consider very carefully before buying dehumidifiers.

Let us give you some clues on how to pick the right dehumidifier with the following detailed dehumidifier buying guide.

1. Ways of operation

Today, the three most popular kinds of dehumidifiers are desiccant, thermo-electric, and compressor.

While the first two types have a certain impact, they take effect very slowly and are unfit for a majority of homes. Fortunately, the last one is the most effective and most widely sold.

Besides, there are some other uncommon types that you do not need to care much. For instance, there are refrigerant-based dehumidifiers that blow the moist air over a frigid surface to turn it into condensation dripping via a drain hose or into a bucket.

2. Size and capacity

Apart from the three most common types of dehumidifiers, you will need to look at their three fundamental sizes. Depending on your preferences and uses, you can choose:

  • Mini portable dehumidifiers – designed for limited spaces like bathrooms, baby rooms, laundry rooms, and small bedrooms (roughly smaller than under 500 sq. ft.).You can put them on your nightstand or a table, in a gun safe, or anywhere else.These often feature a single button for operations and tiny water reservoirs that require frequent emptying.
  • Larger mobile dehumidifiers – quite similar to the first type but a bit bigger in size and capacity.They can remove a greater deal of humidity from the air daily and offer many more features and controls.They are mobile and easy to be moved from room to room thanks to their not-so-big sizes as well as casters and handles system.
  • Whole-house dehumidifiers – these models are a bit massive and require a lot of effort to move.Although people often think of a whole-house dehumidifier as a commercial dehumidifier, it can be used in a household, too.They are connected to the available furnace duct systems and remove moisture in all places in your home.Unlike the first two, these have a complex setup and are difficult to change position, especially some units are designed to hang on your attic’s beams.

However, bear in mind that every model has its own distinctive designs and appropriate positions, so it is essential to analyze your house’s structure and your uses before you spend a big sum on a humidifier.​

3. Calculate the right number of pint

As you see, each dehumidifier comes with a different number of pint capacity. Therefore, you will want to know how many pints are ideal for your house or car in your local climate.

Here, we have worked hard and compiled a standard table that you can consult to calculate the right number of pints in different cases.

Here it is!

Condition Prior to Dehumidifying500 sq. ft.1000 sq. ft.1500 sq. ft2000 sq. ft2500 sq. ft
Rather high dampness (musty smell)10 pints14 pints18 pints22 pints26 pints
Very high dampness (musty smell & damp spots)12 pints17 pints22 pints27 pints32 pints
Wet (sweating walls & feel wet)14 pints20 pints26 pints32 pints38 pints
Extreme humidity (wet floors)16 pints23 pints30 pints32 pints44 pints

Nonetheless, a very apparent issue here is that our moisture removing equipment does not offer the exact pint capacities in the above table. (They are usually 30, 50, and 70-pint models with several non-compliances to our rule.)

Another point is that the table was theoretically built throughout tests with ideal conditions instead of 100% actual conditions. Therefore, it might not be absolutely correct in some cases.

Finally, the table still lacks specs related to the number of cubic feet a dehumidifier fan can pull in per minute. This factor is critical, and the lack of it is likely to make the results incorrect.

In short, as we said, you must know that this standard table is quite subjective, and you should only consult but not completely rely on it. To think out more realistic ideas, you can combine the above chart with the following rules:

  • Your home is in a humid-climate zone – add 10 pints
  • There are often more than two people in the same room – add 5 pints
  • There are a number of windows and doors or other means of ventilation in the room – add 5 pints
  • If you put your dehumidifier near a washer & dryer – add 5 pints

4. Extra features

Added features may not be the foremost factors, but you should neither overlook them. There are a lot of features that are necessary for a specific group of users.

Below are the most notable features that you are likely to want your dehumidifier to have. Let’s see and find out what you need.

  • Automatic features – these might consist of start, pause, resume, shutdown, restart, defrost, and self-clean automatically,… They are very useful as you cannot always have time to adjust to the proper setting or maintain the machine.In this way, your device can not only perform better but also stay with you longer.Also, a timer can save both your time and energy.
  • Drain system – Many people may feel continuous emptying the water bucket is a tiring task. If your dehumidifier can constantly drain via your garden hose, your burden will disappear. Besides, an internal pump is advantageous yet optional.
  • Power – Whether your dehumidifier requires plugging in an electricity source or runs on batteries, you need to examine how many watts it consumes per active hour.Since the chances are that you will turn it on frequently, energy-saving is very vital.
  • Adjustable Humidistat: This function enables users to enjoy their desirable dampness level. Your dehumidifier will switch itself off when the moisture level in the room reaches the pre-set level.
  • Built-in Hygrometer: Without this, you cannot know exactly how damp your room is and hardly optimize the dampness removal process.
  • Indicator lights – you will want these little things to show you the status of the water tank, filters, and other features.
  • Fan speed – One setting is insufficient. You might need multiple fan speeds at different times.
  • Filter – A detachable and washable filter is what you desire.

5. Warranty

It goes without saying that the longer and wider the warranty policy covers, the better a product is.

Indeed, the best dehumidifier brand always provides a preeminent warranty policy.

Inspect what parts of your dehumidifier are guaranteed, and what is not, how long they are covered, whether you can get a 100% refund or partial refund, etc.

These not only specify the quality of the machine but also save you from the hassles later if you are unsatisfied with the item.

6. Price

Don’t buy things that are too expensive for you. Calculate your budget, find out a suitable price range, and merely look for products in that range.

Sometimes, these moisture removing devices become cheaper in particular seasons and zones and vice versa. For example, it is common that a dehumidifier may have a much lower price in a region with a dry climate all year round.

Hence, try to hunt a bargain because dehumidifiers tend to be quite pricey.

7. Reviews

When it comes to shopping, reading reviews of previous buyers and professionals is very helpful.

Positive reviews are even of more concern since these electronic devices can cost you a lot, and it is difficult to find out a suitable model.

You should consult opinions from as many sources as possible because they will let you know better which choice you should invest in.

Nonetheless, try to seek honest and objective dehumidifier reviews because not all reviews are reliable. Besides, don’t just go for the best rated dehumidifier instead of the most suitable one for you.

Also, isn’t it ironic when you have wasted a lot of money and effort to possess the best dehumidifiers for nothing?

Don’t worry. Stick to our preventive guide, and you can improve the longevity and efficiency of your dehumidifying machines dramatically.

And here are the 8 simple tips to maintain the excellency of your dehumidifier!

  1. Leave no chance for ventilation in rooms where your dehumidifiers are active (close doors, windows, turn off ventilation equipment, etc.).As the weather outside generates high humidity, bring the outdoor air into your home will force your dehumidifier to run continuously from day to day.Therefore, block the outdoor air from getting indoor will alleviate the invasion of steam, thus ease the burden and prolong the lifespan of your device.
  2. Put the dehumidifier in an advantageous position to facilitate air circulation in and out of the device.If you position the appliance against the wall or surround it with furniture, it might struggle or even fail to work efficiently.Instead, you ought to allow a minimum free space of 12 inches around its air vents for good air circulation.
  3. Merely turn your dehumidifier on when the moisture level is higher than 50%.Do you find any point in running a dehumidifier when the dampness level is low?It not only forces the appliance to overwork but also costs you an unnecessarily huge amount of energy.You can view the humidistat built into the device or an independent humidistat reader to know how damp the air is.
  4. Replace or clean your dehumidifier’s filter annually.This is to alleviate the accumulation and growth of dust, mold, and mildew in the filter that can make your dehumidifier less effective.You can also ask for some advice from the manufacturer or the provided user manual to know the correct steps of maintaining or replacing the filter.|
  5. Clean the coils annually.It is common that the air blowing through the coils brings with it a certain quantity of dust or even fungal spores into the machine, and they might decrease the performance of your dehumidifier.Therefore, you need to clean these coils at least once per year.Remember to switch off the device and unplug it from any electricity source before you clean the coils.To clean the coils, you can use a spray bottle to mist the coils and wipe the grime down with a soft rag or utilize a vacuum to pull out the dirt.
  6. Inspect the coils for frost when the room air is in low temperatures.The temperature in the room does not need to be too cold for frost to build up inside the coils.If the temperature in your house or office falls below 18.33 degrees Celsius (equal to 65 degrees Fahrenheit), there might be frost in the coils.If you have no remedy on frost, your dehumidifier can hardly work smoothly.One solution is turning the device off completely and wait for the frost to thaw and use the equipment again only when the temperature goes up.
  7. Clean the water tank whenever necessary.The water resulting from the steam condensation is prone to be stale and moldy, which harms your dehumidifier significantly.
  8. Never turn the machine back on within 10 minutes since its last turn off.This is to equalize the pressure inside your dehumidifier wholly, which is proved to extend its longevity.

When am I in need of a dehumidifier?

Wherever your family is living, you will need the help of moisture removing devices if the following things appear in your home:

  • Mold spores – These are tiny dark spots that regularly show up in extremely damp areas like a basement or a bathroom.
  • Obnoxious odors – Fungal growth spores developing in humid areas often look like a thin white coat and emit disgusting smells.
  • Water stains – They ordinarily occur on wooden surfaces, particularly in moist areas. They can wear away your wooden items quickly.
  • Poor ventilation – If your house is not well-ventilated, there should be a dehumidifier to facilitate air flowing and control moisture.
  • Water condensation (especially on glass surfaces) – If there are water drops condensing on surfaces in your home (the most common are mirrors or glass windows), the chances are that people and items in your house are harmed by immoderate dampness.

Above are solely the most typical signs warning about the need for a dehumidifier. Thus, you can also rely on other things or buy a dehumidifier just because it makes you breath more comfortable and fresh air.

What are the benefits of a dehumidifier?

You can benefit a lot from a dehumidifier, but below are the most remarkable advantages:

  • First of all, these appliances lessen the moisture level, which can prevent mold, mildew, dust mites on your furniture, walls, and your clothes. The list goes on.
  • Dehumidifiers get rid of uncomfortable smells that are associated with mildew and mold in the house.
  • Dehumidifiers ensure your family members healthy, specifically children. Low humidity means less irritation and allergy happening to your body (usually skin and respiratory system). It is quite apparent that you can breathe much more comfortably.
  • Clothing dries out more quickly while foods get stale more slowly. Most importantly, there would be no sign of corrosion or rust on metal items, tools, and devices, etc.
  • Dehumidifiers also vacuum a certain amount of dust in your house so it will be cleaner and you will spend less time cleaning.
  • A dehumidifier aids your air conditioner effectively. Although you might not need to turn on both of them at the same time, doing so will double the effectiveness and ease the burden of each device.

Do dehumidifiers operate continuously?

No. Dehumidifiers will automatically shut off when the humidity level meets the settings or/and the water tank is full.

They will only work again when the humidity level exceeds the settings (you can lower the settings) and when you empty the water tank.

Some models with a continuous drain feature can work constantly, but they should also stop at the point where your wanted humidity level is met.

What is the meaning of a dehumidifier’s capacity?

Manufacturers and consumers rate a dehumidifier by the maximum quantity of moisture it can remove from the air in every 24-hour cycle.

For instance, a 50-pint dehumidifier is able to get rid of 40 pints of water from the air in 24 hours.

However, a 70-pint unit may just feature a 30-pint water bucket, and you need to empty the container by hand to maximize the device’s capacity.

Some models come with a direct drain feature, which can constantly drain the water inside the tank into a drain.

Which model costs least to run?

The first thing we can refer to is “Energy Star” rated models. The Energy Star is an international rating that only energy-efficient electronic devices can receive.

Besides, don’t buy an undersized or oversized dehumidifier. Both are prone to cost unnecessarily too much energy to run.

I hear that dehumidifiers might heat up their adjacent area. Is this right?

Yes, it is true. Dehumidifiers would increase the temperature in their ambient environment.

In fact, the higher the temperature around your dehumidifier is, the more moisture it can remove from the air.

Depending on the device’s size and capacity as well as the width of that area, the amount of heat produced will fluctuate a lot.

In narrow spaces, a dehumidifier might increase the temperature in the adjacent areas up to 8 degrees.

On the contrary, in case the weather is too cold, your dehumidifier is likely to stop working.

Thereby, if you are planning to dehumidify a cold basement without any heating equipment, you need to check the dehumidifier you intend to buy. Its specifications will give you some information about operating parameters.

What should I use for a massive space? A whole-house dehumidifier or a number of small units?

In spite of their great advertised performance, the actual effect of dehumidifiers is determined by the airflow in their operative areas. For example, even a whole-house model cannot dehumidify half of your home unless the air can travel smoothly from room to room.

Under such circumstances, you will need to turn on fans in your house (ceiling fans are the best) to facilitate the air to travel among rooms and to the dehumidifier.

Or else, you can buy multiple dehumidifiers and put them at different corners of your house.

Are dehumidifiers quiet?

Although most dehumidifiers are not as noisy as a portable air conditioner, they might emit some sounds rated approximately 56 dB, which is similar to human speech.

Whether a device is too noisy or not is a subjective topic, so you can test different places to put your dehumidifiers in your bedrooms, living rooms, or anywhere else in your home to find out the ideal positions.

What differentiates a dehumidifier with a pump and one without a pump?

A built-in pump is optional yet adds incredibly more convenience. It can drain the water container automatically via a pipe connected to the drain system (e.g., water is drained to the garden hose or a sink, so on).

If your dehumidifier offers no pump, you need to empty the water tank manually.

Of course, a dehumidifier with a pump is more pricey but more helpful in cases when you do not have time to drain water, the water container is weighty or bulky, or the device is hard to reach like ones hung on a crawl space or an attic.

How wide is the area that a 70-pint dehumidifier can take effect on?

Normally, a 70-pint dehumidifier can have impacts on a space of from 650 to 1600 square feet, which is also determined by the area’s conditions.

In other words, a 70-pint dehumidifier may be able to dehumidify an only 650-square-foot space in ultra dampness but up to a 1600-square-foot area in low humidity.

How do dehumidifiers work?

The majority of dehumidifiers use an internal compressor and fan to pull the damp air via their inputs.

The air then flows across cold coils to condense the steam into a container. Finally, dry air is released back to the outside space.

What is the ideal humidity setting?

The optimal humidity level for any space should be between 30 and 50%. However, it should be higher in hot weather and vice versa.

If the dampness level in your home exceeds 50%, mold and mildew are likely to show up. However, too dry is quite uncomfortable and may cause chapped skin.

What is the coldest temperature a dehumidifier can be active in?

Almost every residential dehumidifying equipment can function in from 41 to 44 degrees F temperatures.

Meanwhile, desiccant models used in industries can even work in subzero temperatures.

Because of the differences among each device, you had better examine the specifications to find out the particular operative temperatures.

Where should I place my dehumidifier?

Where you put your dehumidifier is very important because the wrong position can ruin all of its efforts. Here we will guide you on how to place your dehumidifiers properly.

  • Enable air circulation around your dehumidifiers so that the devices can perform better.Numerous models can be attached to the wall if they feature an air discharge mounted on the top. But if your dehumidifying appliances do not have that, never put it against the wall or furniture but give it a lot of space around instead.You should leave a space of at least 7 to 13 inches around all sides of the equipment for airflow.
  • If you have a hose to drain water from the container, fix it in a tub or a sink.Besides, periodically inspect to ensure the hose is still in position and drains rightly into the tub or sink. (You can use twine to keep the tube in place.)Never leave the hose near electrical cords or outlets if you don’t want to get an electric shock.The tube should be as short as possible because a long tube is cumbersome and may make people stumble.
  • Keep your equipment far from dirt and dust sources like woodworking machines, or else debris will accumulate inside and hinder the function of your dehumidifier.
  • It is unquestionable that your dehumidifiers should be put in the dampest places such as laundry rooms, bathrooms, or basements.While your boat is moored to a dock, you can use a dehumidifier to reduce the high humidity on it, too.
  • Except for whole-house models, other types of dehumidifiers should be only used in one room with all means of ventilation blocked (doors and windows closed,…).Although a dehumidifier can be set up between two rooms, it has to work harder but is less effective.
  • Whether your moisture removing equipment is wall-mounted or mobile, try to place it as near the center of the room as possible.
  • You can incorporate the dehumidifier into your HVAC system. Compatible models are typically huge ones like a Santa Fe Dehumidifier, which is specifically designed to connect with your HVAC system.The installation process may involve a ducting set and some other accessories. And it is quite tricky, so the chances are that you would need the help of a mechanic to integrate a dehumidifier with your HVAC system.
