Some appliances consume excess energy and they can therefore significantly affect your bill. When selecting an appliance, you should carefully consider this factor. High efficiency systems deliver maximum performance while consuming minimum energy.

The KSTAD70B is an Energy Star rated dehumidifier that is optimized to deliver impressive performance while consuming minimum power. This unit is therefore designed to help you save money. In addition, its auto-restart function allows it to restart automatically after a power outage : a very nice feature if you are away for some time.

A dehumidifier stores the collected water in a reservoir unless it is connected to an external drain. The KSTAD70B comes with a 1.3-gallon water tank for holding the captured water. In addition, its transparent water level indicator enables the user to monitor the amount of water in the tank.

The unit is designed to alert the user when the tank is full. If the tank is not emptied, this dehumidifier shuts-off automatically to avoid water spillage on the floor. With these features, you don’t need to worry that the unit will flood your house in your absence.

In case you would like your dehumidifier to run continuously, it is recommended that you use a drain hose instead of a bucket. This option enables the system to run without shutting off or alerting the user to empty the tank. If you live in a high humidity place and you are not always available to empty the tank, then this option is ideal for you.

An easy maintenance, here.

An easy maintenance, here.

If you intend to move your dehumidifier from one part of your house to another, then you should go for a portable system. The KSTAD70B features caster wheels that make it easy for you to wheel it from one room to another.

The KSTAD70B features a removable filter. You can easily clean this filter either by washing or vacuuming it. Other features offered by this unit include the following:

  1. A 7.22ft cord
  2. A power rating of 720 watts
  3. A maximum airflow of 188 CFM
  4. A maximum noise level of 56 dBA
  5. Normal, turbo, and auto-defrost settings
  6. A 24-hour timer and an LED display

Now, two elements are calling for a less-than-perfect grading.

  • First, the loud compressor that runs when the dehumidifier operates can be a nuisance if you intend to work or read in the same room as the dehumidifier operates.
  • Second, the warmth that the compressor generatesΒ is less than optimal.

Pros

  • Minimum power consumption. Many users are impressed by the energy needs of this unit. Some have revealed that its energy consumption is lower than that of some lower capacity systems.
  • A sense for details and ease of use. With every detail of the cycle of use well planned, such as accurate humidity measurements or the auto-restart function, this dehumidifier is smarter than most competitors.

Cons

  • Generates heat. A good fraction of users has observed that this unit generates heat that is enough to raise the temperature of your house by a few degrees. This is undesirable in hot places, especially during summer.
  • Louder compressor. This unit may not be an ideal choice for places that are expected to be quiet such as bedrooms, or home offices.

Users' feedback

Users quotes on Amazon.comThe Keystone KSTAD70B Dehumidifier is Energy Star rated as most are today, the 70 pint a day rating is average for most this size and the 1.3 gallon tank with a water level view indicator (seen on front of unit) is also standard on most modern Dehumidifiers made today. This unit covers up to 3,800 sq. feet and uses R-140a (1,1,1-trichloroethane) as a refrigerant. A hose connection for direct draining is easy to setup saving the need to empty the holding tank daily. At 40 lb. the Keystone is on the heavy side, it does have casters wheels making it easy to transport once on a hard floor or carpet that's not too deep pile. Removable, easy-cleaning dust filter with a clean-filter alert is something you won't find in every brand but a very good idea, trapping and preventing mold spores or other bacteria is always helpful to help prevent unhealthy conditions. Very rare but still known to be possible is Legionnaires' disease, when found it's in devices that contain water or warm water vapor. I always stress the need to clean water tanks and holding areas that contain standing water in warm moist conditions with bleach, bleach will kill mold on contact better than any other household cleaner. The 24 hour timer works well and if power is lost a memory returns the unit to the settings programed prior to the power loss, many other brands don't have a built-in settings memory. LED display is easy to read and set. This has a 5 year warranty too! Noise level is what you'd expect, not too loud but you know its running."

Users quotes on Amazon.comMy husband and I owned a 50 pint dehumidifier that was recalled this past winter. We wanted to purchase a unit that would last a lot longer and would be better constructed. The 70 pint KeyStone dehumidifier had excellent reviews and appeared to fit the bill. We were pleasantly surprised to learn that the units electric consumption is less then the Gree 50 pint GE that was recalled and does a much better job at maintaining a low humidity level in our full basement, and actually cost less. I would recommend the KeyStone 70 pint dehumidifier based on its performance over the past few months that we have owned it."

Conclusion: KSTAD70B by Keystone

The Keystone KSTAD70B dehumidifier is a strong dehumidifier that delivers on its promise to remove up to 70 pints of moisture from the air in a day. This unit consumes minimum energy and features a removable filter that is washable, as well as smart functions that no competitor offers.

However, its compressor is louder than it should be, which is a big no-no for the Air Geeks. Going by the features and the performance of this unit, it deserves its rating of 4/5.
