How to Choose a Low-Temperature Dehumidifier

Choosing the right kind of dehumidifier requires proper research and time from your end. However, as a general rule, make sure to look out for the following characteristics when making a purchase.

Dehumidifier Size

Dehumidifiers that are used commercially come in three different sizes; 70 pints, 50 pints, and 30 pints. This size describes how much moisture these units can capture in one day and have no relation to any physical availability, dimension or the capacity of the reservoir. Instead, they depend on the room you need to place them in.

A smaller room will be perfect for a 30-pint unit, whereas a medium room can make use of a 50-pint unit. Similarly, you can use a 70-pint unit for an entire household as well as large bedrooms. These large dehumidifiers do not run for a long time, and this helps in prolonging their lifespan.  However, if you're on a short budget, you can always go for a 30-pint or 50-pint dehumidifier, since they are less expensive.

Quiet Operation

Noise of any kind can be a real nuisance, and when investing in a product such as a dehumidifier that works all through the night, it is essential to consider this aspect. Dehumidifiers that come with two different fan speeds can be quiet at low humidity levels; however, some units make slight noise even at the low setting.

It is a good idea to purchase a dehumidifier that is extremely quiet and does not make any noise at all. This way, you can enjoy their high functionality along with a night of good sleep.

Automatic Shutoff

Dehumidifiers can run for a long time at low temperatures. However, running of a unit for prolonged hours without a full tub can be harmful. This can weaken it and even ruin the mechanical system of the dehumidifier.

So, it is essential that you get a humidifier that comes with a timer or an automatic shutoff feature. This allows you to sleep peacefully without getting up in the middle of the night to turn it off or check the tank.

Some dehumidifiers also come with an indicator light that tells you when it needs to be refilled.

What is a Low-Temperature Dehumidifier Best For?

These units help in making your household inhospitable to allergens such as mold, dust mites, mildew, and germs. Since these units do not make too much noise, they can run efficiently in the background without disturbing anyone.

What Makes a Dehumidifier Great for Use in Low Temperatures?

Standard dehumidifiers can handle the humidity in average or high temperatures, but the condensers may struggle with wet climates or cold seasons. Here’s a look at why low-temperature units are perfect for these conditions.

Designed for Cold Rooms

The most significant benefit is that manufacturers build these dehumidifiers to withstand cold temperatures. They work best in your chilliest rooms that seldom receive heat, such as garages and basements. You’d be surprised how much humidity can rise in these spaces.

Protection From Mold and Mildew

Dark rooms with high humidity are catalysts for mold and mildew spores. If left unattended, they can rapidly grow, causing damage to structural components and creating foul odors. Dehumidifiers not only remove the moisture in the air that allows for these conditions to proliferate, but they also help with air circulation to remove the bad smells.

Eliminates Bacteria

Besides causing illnesses, harmful microbes can make it difficult to breathe. Cold rooms are havens for these lifeforms, eventually leading to serious health conditions like sick building syndrome. Air conditioning systems sometimes enable airborne diseases to travel around the office or home. Low-temperature dehumidifiers can solve this issue for you.

What is a Low-Temperature Dehumidifier, and How Does it Work?

These appliances work exceptionally well in regions with wet weather, cold temperatures, and high humidity. Standard units can handle anything above 60℉, while low-temperature dehumidifiers can function as far down as 40℉. The primary reason is that the components are designed to withstand these conditions without icing up.

There are different types of dehumidifiers. For instance, some have condensers, while others work with heat pumps. They operate by extracting the humidity from the air in various ways, pushing dry air out of an exhaust that also serves to warm the room.

Low-Temp vs High-Temp Dehumidifiers: How Do They Compare?

Are you wondering why you should swap out your high-temp dehumidifier for a low-temp version? Here are a few factors to consider.

Different Climates

The most obvious difference is that one can only handle temperatures above 60℉ while the other can drop lower. High humidity also appears in wet climates, and you’ll suffer from the same problems, especially in basements, attics, and garages. The components may be similar, but a low-temperature unit will function differently to handle the colder environment.

Defrosting Time

You can still use high-temperature refrigerant humidifiers for colder climates up to a certain degree. The problem is that the time it takes to defrost the water into the pan will take longer, which is why the low-temp option is recommended. The defrost cycle is shorter, leading to quicker dehumidification.

Suitable Locations

You may have a warm home with a gorgeous patio, with the sun beaming in while you relax under one of the best high-speed ceiling fans. However, your basement may hold a lower ambient temperature. So while you’re running a high-temperature dehumidifier in your living room, it may not be helping the colder spaces. 

Life Expectancy

One of the top reasons not to use high-temp units in cold climates is the damage it can cause to the internal components. You’ll drastically reduce the device’s lifespan, and you’ll pay more than is needed for maintenance or repair costs. It will also work harder to remove humidity, so expect higher utility bills.

Aspects to Consider Before Buying a Low-Temp Dehumidifier

Before you head out and buy one of our recommended low-temperature dehumidifiers, there are a few aspects you should look at first.

Coverage

It’s not enough to merely find a dehumidifier that can handle low temperatures. If you have a large basement or storage room, you’ll need to ensure the unit’s capacity. 70-pint machines can remove humidity from bigger spaces than 50-pint units.

Water Tank and Drainage

The water tank size is also a significant factor, as it indicates how quickly it will become full. You’ll need to change smaller tanks more often. Even better, if the dehumidifier has a drainage pump and hose then it’ll do this for you.

Weight and Size

The dehumidifier’s size also comes into play. Your room may be small, so you won’t have room for a massive unit. You also shouldn’t purchase a heavy appliance if you intend to move it around your home periodically during the day.

Warranty

Not all manufacturers supply a warranty for their components. We recommend you find a dehumidifier that does have one. In low temperatures, parts may fail sooner than their intended lifespan. It will help if you can receive replacements at no extra cost.

Conclusion

We hope one of these five dehumidifiers ends up being the perfect unit for your home and we hope that this guide helped make your search easier and less time-consuming. Invest in the right kind of dehumidifier and make sure you get your money’s worth.

People Also Ask

Do you have a few questions remaining after reading our guide? Let’s see if we can answer them for you.

When Should You Use a Low-Temperature Dehumidifier?

The best time to use a low-temperature dehumidifier is in regions that drop below 60℉. Standard units will have longer defrosting times, causing damage to their components in the long run. If you see mildew or mold forming in your rooms, it’s time to buy one of these machines.

How Do You Run a Dehumidifier in Low Temperatures?

You’ll need to place it in a central location to cover as much of the space as possible. Ensure that you keep the humidity as close to 50% as possible. If there’s a water tank, you’ll need to empty it as soon as it reaches a specific level.

Do You Need a Dehumidifier in the Winter?

If the humidity is high in winter, you need one. Dampness can spread in your garage or basement, resulting in bacteria, mold, or mildew. It can also cause damage to your walls and floors. 

What Should I Set My Dehumidifier To in the Winter?

You can set it to any amount below 60%. The recommended level is between 40% and 50%. If you’re looking for maximum comfort, you can aim for between 30% and 60%.

What Type of Refrigerant is Used in a Low-Temperature Dehumidifier?

Low-grain refrigerants excel in commercial environments with harsh conditions. They can withstand both low and dry conditions without suffering any damage. However, if you’re looking to place a dehumidifier in a residential space, you’re better off with a desiccant unit.

How Do I Keep My Dehumidifier From Icing Up in Cold Temperatures?

If you find the condenser coils or evaporator, the chances are that there isn’t enough air blowing over them. You should remove the cover and check the fan, ensuring that no dust or lint blocks it. Make sure that the blower wheel isn’t damaged or dented. You can also heat the room with a separate device.
