It’s presently winter period, and the colds are biting hard most especially in our houses. Everywhere is cold and wet, with the high tendency of molds and mildew growth. Bad odors are being released all around in several parts of your house most notably in the water prone areas like the basement.

This translates to you having to find a solution to this persistent problem urgently, and you are on the search for best dehumidifier for cold basement which has led you to this page. Congratulations, you are on the right track because we’ve done all the researches for you.

Do you need to run a dehumidifier in basement in winter?

I know you would want to ask this but I have you in mind already. YES, you can but it depends on the temperature and the huidity level. You can operate your dehumidifier in the cold weather, yes, you can. In fact, the relative humidity levels are always raised during this period which is the main reason why we need dehumidifier.

However, the coil of your unit are very sensitive to temperature and they may get frozen if care is not taken. therefore, you should pay a close attention to the device. If the temperature drops below the ideal level, you should turn it off

In short, you should examine your humidity level very well before starting the dehumidifier. If you have the relative humidity above 50%, you could start the dehumidifier but if it is lower than 40% in cold weather, you may want to wait till the humidity level has increased

But I need to tell you what dehumidifiers does in a basement during cold. They prevent overdamping of apartment with moisture, thereby preventing growth of molds and mildews.

During winter, dehumidifier tends to be more specific in action due to environmental changes. In other words, some are known to be very good and active in the room or a garage but are poorly efficient in the basement not to talk of a cold basement. Henceforth, the need for the best cold basement dehumidifier.

1.) Basement Temperature range:

During cold weather, temperatures are known to drop as low as -4 degree Celsius sometimes, a dehumidifier to be used in such a condition must be able to withstand such environmental rigors in the basement so as to work correctly. Henceforth, It is necessary to first measure the level of temperature in your basement before deciding which dehumidifier to buy.

No need to worry about that as we have researched and reviewed the best dehumidifiers suitable for your basement condition. Dehumidifiers with average or higher operating temperature than that of the basement temperature is needed, dehumidifiers with lower operating temperature are known not to function properly there.

2) What Size is the dehumidifier’s water tank:

The size of the water tank of the dehumidifier matters a lot when deciding which dehumidifier to buy. If you buy a dehumidifier with a big tank size, it will give you the freedom of not running it for days or even weeks without draining it. Else, if you buy a dehumidifier will small water tank, that will give you the frequent problem of having to frequently and continually empty it daily or every two days.

For example, if a dehumidifier with 70-pint capacity damp vapor at 10-pint per 24 hours but has a 7-pint water tank, this will lead to a need for constant draining of the water tank up to six times within a short period (probably every seven days) when functioning maximally.

This can lead to additional stress on the part of the user and this reduce the person’s life quality and even likely to reduce your financial income as time spent on severally draining water tank can be productively used on something else meaningful. However, to avoid all these unnecessary stress, the water tank can still be drained with gravity or drained mechanically by pump.

The size of the water tank also affect the size of the dehumidifier to use in the basement.  This help to judge how effective the dehumidifier will work. By size, we mean the space area (sqft) of the basement in relation to the the dehumidifier efficiency.

3) Automatic restart and Continuous mode:

Good basement dehumidifiers should have and I quote “an auto restart” command function in case of a temporary power outage for whatever and should be able to restart itself when power is restored. Failure of the dehumidifier to restart itself when power has been restored will lead loss of efficiency and value.

The automatic continuous mode helps the dehumidifier to automatically detect the level of relative humidity in the air and still continually operate efficiently as required without any interruptions.

4) Built-in pump or gravity drainage:

The dehumidifier should come with built-in gravity drainage functionality and a small rubber pipe which is connected to this from the floor drain of the basement so as to drain off the dehumidified vapor into the external drainage system of the house.

More so, dehumidifiers with built-in gravity drainage do not pump drainage, hence helps save expenses to have been spent on pumps. Dehumidifiers with In-built drainage are better preferred to dehumidifiers with no In-built gravity drainage.

5) Defrost mode and desiccant:

The basement is most likely to be the coldest part of the house and this is likely to affect the effective functioning of the dehumidifier. The best dehumidifiers operate efficiently at defrost mode in temperatures defrosting frost that has been built up in the dehumidifier’s compressor as it could affect the dehumidifier’s working efficiency.  This feature is a very important determinant factor in distinguishing out the best dehumidifiers.

You, however, do not need to worry about frost build-ups in dehumidifiers if the humidifier is a desiccant type and they also have a larger operating temperature range. Desiccant humidifiers are recommended over compressor ones.

6) Warranty:

Generally, Products with Warranty are more reliable and when considering which basement dehumidifier to buy. Warranty gives you the power to confidently buy any product without having to panic about faulty show-ups.

7) Price:

Getting the right product for the right price, thereby saving money is the cost-effectiveness of any dehumidifier in the market. We only rated high basement dehumidifiers that offer a good value for the right price, since you would love to spend wisely. Also, in this review, we avoided cheap dehumidifiers with inferior quality were all avoided and excluded from the top rated.

Recommended Top Dehumidifiers for finished or unfinished cold basement

1) Frigidaire FFAC7044U1 70 Pint dehumidifier – best Technology oriented 

This product is the only technology-oriented dehumidifier with Wireless connectivity control that I’ve used so far; it has helped keep my basement dry. It gave me a wow surprise even on our unfinished basement by reducing the humidity level from 65-50% even when it was raining continuously for about 3 days.

Its quality is unparalleled with other dehumidifiers in many aspects and by many standards. I adjudge it as the best basement dehumidifier I’ve used so far firstly because of Its warranty of 5 years sealed system plus 1-year full parts and labor, it even auto restarts automatically whenever I emptied the water tank or when there is a power outage.

Its durability is based on the fact that it continuously drains compared to those dehumidifiers whose unit are built with a pump. This is very helpful since you won’t always have to drain the bucket of water.

What intrigued me most about this Frigidaire product is Its Wi-Fi feature, it actually makes it easy and controllable for me from my smartphone anywhere in the house. You just need to download and set up the app which also works with Alexa and google home.

It operates quietly and noiseless in the basement. It’s a good fit and will be a good value for your hard earned money should you decide to go for this.

It has a product dimension of 15.4 x 11 x 24.3 Inches and its 1.6 gallons (6 liters) tank capacity is a super plus to the product. The dehumidifier automatically restarts itself just like Frigidaire in the case of power outage; the water storage tank helps hold about 1.6 gallons of water helping put off worries of having to empty it several times in a day.

It auto shuts down itself when the water tank is full and instantly auto restarts when the water tank has been emptied. Also, I was able to control the humidity level that I wanted in my basement, and If you want it to drain the water continuously, you could set it to connect the garden hose to it and gravity-drain it.

It runs on very low energy and hence saves money on electricity bills, it has a low-temperature operation and also has 2 years’ warranty; it is also energy efficient and has an automatic reset.

This dehumidifier worked greatly in our unfinished basement of approximately 1500sqft, sucking up about 4 gallons of water in 24 hrs. To my wow, all these were done quietly as though nothing was working in the basement.

The energy-saving feature is a plus on tosot, I noticed a very striking save of up to 30% reduction on the energy bill. Everything about tosot is much like a win-win deal because it is also effortless to fit and replace

Although the water bucket is small, I would recommend that you connect a hose to it so that the water could drain easily into a sump pump. Even though my basement doesn’t smell and not damp at all, this unit helps maintain the humidity level to 40-43%
