Setup and Usability

Keystone High Efficiency Dehumidifier Control Panel

The Keystone KSTAD354D is designed to be used even by people who are not tech-savvy. It comes with a straight forward control panel that features a visible LED screen, which indicates timer settings. The panel also features straight forward buttons that allow users to choose their desired humidity levels. It enables them to increase or decrease the RH levels by 5% with each click.

Furthermore, users may select their ideal fan speed between high or standard to suit their individual preferences.

Note: While using this unit to test its dehumidification efficiency, we noticed that users can choose between a minimum humidity level of 35% and a maximum of 85%.

The Keystone KSTAD354D dehumidifier also comes with extra features that make it even more user-friendly as discussed below.

Auto-Restart Feature: This feature allows the device to turn on automatically after a power outage. It also saves the previous adjustments. The unit will turn on after 3 minutes, which protects it from damage that may be caused by a power surge.

Accurate Humidity Reading: It has a hygrometer that measures the levels of humidity in a room and displays the same via an LED display. This feature helps to maintain the ideal levels of humidity effectively.

Clean-Filter Alert System: It notifies users when the filter has become clogged with dirt. This function helps ensure the optimal performance of the device, and more importantly, maintaining clean indoor air.

Full-Tank Alert System: This feature warns users when the tank is about to fill up. It also shuts off the unit to prevent overflow.

In addition to these features, the unit also supports three methods of water drainage:Keystone High Efficiency Dehumidifier Tank

  • Manual

This appliance comes with a reservoir with a capacity to hold 13 pints of condensate. Upon filling up, users may remove the bucket and empty the water into a drain or sink. This method calls for a lot of attention, and it isn’t ideal for areas that experience excessive dampness.

  • Gravity Drainage

The unit comes with a drain adapter that allows users to connect a garden hose to the unit and direct the condensate into a drain system. This method works best when the drain system or sink is located on a lower level than the unit.

  • Continuous Pumping

This method is similar to gravity draining, but instead of relying on natural forces, it uses a condensate pump. This feature helps when condensate needs to be drained on a higher-level drain system or sink.

Note: While testing the drainage options, we noticed that the unit stops working when the reservoir has been removed and resumes operation when the tank is reinstalled.

Cleaning and Maintenance

Keystone High Efficiency Dehumidifier Filter

When it comes to cleaning and maintenance, the Keystone KSTAD354D doesn’t provide many problems. When the filter warning system lights up, users must remove the filter and clean it immediately:

  • For this purpose, users can pull the filter from the top of the unit or remove the bucket from behind the appliance and pull the air strainer downwards.
  • They should then proceed to wash it with clean water and let it dry completely before reinstalling it back into the unit.
  • The condensate reservoir must be cleaned from time to time to prevent mold growth. They should also clean the grill using a vacuum cleaner with a brush attachment or utilize water and a mild detergent, particularly when it’s extremely dirty.

We Recommend: Do not splash the grill with water. Doing so may cause short-circuiting and rust.

Areas for which It’s Best Suited

The Keystone KSTAD354D is sufficiently versatile to work well in multiple areas of a home. This unit comes with different features to aid this ability, as shown below.

  • Vacation Homes: The ability of the automatic restart feature to save previously modified settings and turn on the device after a power outage makes the unit a perfect solution for use in areas where people don’t usually visit.
  • Power Outage Areas: The automatic restart feature also makes the unit an excellent pick for people who reside in areas that experience frequent power outages.
  • Basements near water bodies: The ability to remove 35 pints of moisture from the indoor environment coupled with the continuous drainage option makes this unit suitable for extremely-humid areas.
  • Drier rooms, Bathrooms: Its 24-hour timer makes this device ideal for areas that experience moisture problems at given times and the areas which lack proper ventilation.
  • Flooded Areas: The expedient fan speed means that users can utilize the unit to remove excess moisture in areas that need a quick fix.
