The Basement Dehumidifiers Evaluation

Frigidaire FFAD7033R1

A dehumidification appliance that does what it’s supposed to do and much more, the FFAD7033R1 keeps mold and mildew issues at bay through its effective operation. To make its presence almost unnoticeable, it produces a mere 51 decibels when set on the highest of its 3 fan speed settings. The humidistat provides you with full control over the indoor humidity level to be reached, so customization is at its fullest. When it comes to design, it is a portable appliance that you are bound to fit anywhere you please, measuring 24-7/16” in height, 15” in width, and 11-5/8” in depth. There are no real downsides to it, the only minor flaw being the fact that it doesn’t automatically restart its operation from where it left off in case there is a power outage.

Moisture Removal

In terms of efficiency, few dehumidifying appliances come close to this Frigidaire entry as it is rated to remove up to 70 pints of moisture per day. Obviously, its moisture removal rate varies depending on the size and humidity level of the space you intend to utilize it in, but this aforementioned stat is its peak potential. To enjoy the best results possible when dealing with a highly humid environment, we recommend that you place it in the center of the room, or at least orient it with the back at the center of the room and the front towards the wall.

Gravity Drainage

Having to waste time emptying the tank is one of the most annoying aspects of owning a moisture removal appliance. The 13.1-pint capacity of this model is large enough to ensure you won’t be emptying it all that often. However, completely freeing your mind of this task isn’t bad in the least as an actual continuous operation is possible even when you are away from home. As it features side drainage, with the simple installation of the included drainage adapter and hooking of a hose you will be able to enjoy a continuous operation of the appliance.

Mention Worthy Features and Specs
  • Able to operate in environments where temperature is as low as 41 degrees Fahrenheit, thus being perfect even for the basement.
  • If you do not opt for continuous drainage, the appliance automatically shuts off when the water tank is full, and you are alerted of the occurrence so that you know to empty it.
  • Features a top handle, integrated side handles, and caster wheels that make it a lot easier to move the appliance around the house.
  • Features a washable mesh filter which helps reduce airborne particles, bacteria, and room odors, making your home a safer habitat for you to live in.
  • Features a 6.5-foot long power cord which makes extension cords obsolete.
Energy Efficiency

The Energy Star certification it comes with is more than enough proof of how well this appliance does in the energy efficiency department. It is rated by the manufacturer with having a power draw of 745 watts, this being the reason why it received the sought-after certification that is only given to appliances that boast low power consumption when compared to the average of the market they are in. Besides consuming little electricity to start with, it features a 24-hour on/off timer which helps further reduce operating costs as it enables you to decide the exact operational length you need for humidity to reach a normal level.

What We Like What We Dislike
⇒Can operate in areas where the temperature might drop to 41 degrees Fahrenheit ⇒It does not automatically restart with the selected settings after the occurrence of a power outage
⇒Full bucket indicator announces you when the reservoir needs tending to  
⇒Low power consumption – only 745 watts  
⇒Air cubic feet per minute rating of 182 when set on the highest setting  
⇒Low noise production levels – outputs only 51 decibels on the highest speed setting  
Verdict
Undoubtedly the best product on its market, the FFAD7033R1 ensures mold and mildew will be nothing more but bad memories of the past as it boasts a high 95% efficiency and is able to remove up to 70 pints of moisture per day. Furthermore, it can withstand battling high humidity issues in large areas of up to 1400 square feet, and it delivers a convenient and intuitive operation, so there are only advantages to be reaped if you use it.

Keystone KSTAD70B

With a high efficiency in removing excess moisture from the air, during our tests being able to reduce it from 70% to a healthy 55% in only 4 hours, this Keystone entry is an obvious pick for those who are faced with the imminent danger of mold and mildew appearance as a result of an unhealthy humidity indoors. The humidity level you want to be reached indoors can be adjusted in 5% increments, so you enjoy full customization over its operation in order to suit your specific needs and preferences. With a tested efficiency score of 94%, there is no sense in doubting the performance it puts at your disposal, its 70-pint dehumidification capacity and 4500 square feet maximum area coverage making it perfectly suited for any area, regardless how large or humid it is. Of course, before we move on and analyze some of its most important aspects, we must mention the fact that the manufacturing company backs it against defects for 1 year, repair costs being covered during this period of time.

Drainage System

There are two options you can pick between when it comes to drainage manner – either do it manually or opt for gravity drainage. However, be warned that it doesn’t come with an adapter that helps employ gravity drainage, so you will have to buy one separately. Considering that this isn’t a costly investment, it is worth making as it spares you of a lot of trouble. If you do opt for gravity drainage and install the adapter, you won’t have to check on the water level of the collection reservoir ever again as moisture will be discharged as soon as it is collected. Your second option is manual drainage, which actually isn’t all that bad with this specific model considering the fact that the water tank has a 10.4-pint capacity, making it unlikely for you to need to empty it all that often.

Convenience & Ease of Use

As it is very easy to input settings on the LED display it features, we can confidently state that this is one of the easier to use products on the market. Thus, no matter if you want to set the timer function, or raise or lower the humidity level to be reached, you won’t have a hard time doing it as there are only a few buttons that you have to push. It features a transparent and easy-to-read water level indicator which allows you to conveniently keep an eye on how much moisture has been collected up to that point. There is an audible alarm which sets off in case you don’t observe that the collection reservoir is full beforehand. Obviously, we must mention the automatic shut-off that activates when the tank is full in order to prevent overheating as it not only helps protect your investment but helps make your life easier as you needn’t think about the level of moisture it has collected if you go for the manual option.

Mention Worthy Features and Specs
  • High moisture removal capacity of up to 70 pints per day when placed in a space of up to 4500 square feet.
  • Works even in low-temperature conditions – withstands temperatures as low as 41 degrees Fahrenheit.
  • Automatic restart feature remembers the selected settings during a power outage to spare you from reselecting them.
  • Produces 54 decibels when set on the low-speed setting, and 56 decibels when set on the high-speed setting.
  • Clean filter alert lets you know when you should tend to the washable filter it comes with.
Energy Efficiency

Although it is rated at 720 watts, it draws less depending on the specific humidity issues at hand. Even with this initial rating, it remains one of the most energy-efficient devices of its kind on the market. Thus, it comes as no wonder that it is Energy Star certified, its operation not raising your costs on the electricity bills all that much. But the feature that truly makes it optimal in terms of power consumption is the 24-hour timer it comes with as it allows you to establish a functioning schedule for the device so that it won’t run for longer than it’s actually needed.

What We Like What We Dislike

Black&Decker BDT70PWT

Our personal favorite, the BDT70PWT, has the capacity of removing up to 70 pints of moisture over a 24-hour time period. This makes its efficiency in highly humid environments undeniable, keeping mold and mildew at bay with ease. However, one of its most impressive specs is the capacity of the water reservoir, as it can hold a maximum of 16.2 pints before it needs to be emptied. But if you want to enjoy convenience at its finest, we recommend you take advantage of the continuous drainage option it puts at your disposal.

As it only produces 53 decibels when it operates, you need not worry that it might present a distraction, being quiet enough for rooms like the nursery or the study. The automatic defrosting feature ensures the coils are kept safe, so you can confidently rely on it to operate at its peak for numerous years.

It features a 24-hour timer that enables you to select the desired operational span in order to reduce operational costs and optimize its efficiency in regards to your needs. Although it is a bit heavier than most dehumidifying appliances, this aspect does not present a great problem as the caster wheels make it a cinch to move it from one room to another. Of course, we cannot end without praising its great price to quality ratio as it is quite affordable considering the performance it puts at your disposal.

What We Like What We Dislike
⇒High 395 cubic feet per minute air flow rating exceeds industry standard ⇒On the heavy side – weighs 50 pounds, which means it won’t be very comfortable to move it on your own
⇒Quiet operation allows you to place it in any room you desire – only 53 decibels on the highest speed setting  
⇒Full bucket indicator keeps you updated with when the time comes to empty out the water collection bucket  
⇒Allows you to opt for continuous draining in order to save time on routine water reservoir emptying

Frequently Asked Questions

What does a dehumidifier actually do?

When excessive humidity becomes an issue in an indoor space, you will start to feel rather uncomfortable sitting it that area as the environment becomes muggy. Furthermore, the risk of mold growth exponentially increases, a “guest” you surely do not want to make an appearance. In excessively damp rooms and environments, the dehumidification system plays a crucial role as it helps reduce moisture and maintain healthy, adequate levels of indoor humidity.

At what level should relative humidity be kept?

For most indoor spaces, the ideal relative humidity should range from 45 to 50 percent. If relative humidity drops below 30 percent, your health is directly affected as issues like irritated skin, irritated respiratory passages, and the increase of flu viruses occur. However, relative humidity levels above 50 percent are just as harmful, if not even more dangerous. As high humidity becomes an issue, the environment becomes prosperous for mold and mildew growth, and the spreading of bacteria.

What are the dangers of high indoor humidity?

As aforementioned, high indoor humidity leads to mold growth as the environment creates proper conditions for the appearance and spreading of this dreaded fungi. For people who suffer from allergies or asthma, the presence of mold spores in the air they breathe presents a great threat to their health as these afflictions are affected by fungi spores. Furthermore, inhaling these spores is dangerous for clinically healthy people as well as they cause the contamination of respiratory tracts and lungs. Besides directly presenting a threat to your health, high indoor humidity is dangerous when it comes to the structure of your house and the state of wood furniture pieces as well, deprecating their quality.

What happens to the water collected by the dehumidification device?

Most dehumidifiers feature manual water removal in the form of a collection bucket where the water is automatically stored during the operational process of the appliance. When this bucket is filled, the dehumidification system stops working until you empty it. Other types of dehumidification systems offer the possibility of continuous drainage with the help of a hose which transports the water collected to an external container like a drain or outside of a window. Obviously, it is a lot more convenient to opt for continuous drainage as you will not be required to monitor the device and do any maintenance work on it from this point of view.

How long does it take for a typical dehumidifying appliance to considerably lower humidity?

The answer to this question depends on the size of the room/area the dehumidification appliance is placed in, as well as the device’s capacity. In a medium-sized room/area, it should take approximately 8 hours for a 30-pint dehumidifier to bring humidity levels down to 50 percent if they were above 70 percent before the appliance’s operation commenced. However, if we are talking about a damp building, it could take more than a week for the device to bring humidity to a healthy 50 percent.
