Keystone KSTAD70A

The Keystone KSTAD70A 70 pint dehumidifier has a very practical look. However, considering the amount of moisture it will pull from air in a 24 hour period, it’s actually a compact unit that won’t look out of place in many areas of the home. Aside from looks this model is very portable, easy to use and maintain, and above all pretty efficient. All of this will ensure the air in your home is kept at a comfortable level when humidity is high.

Review Details

This 70 pint dehumidifier has two drainage options. You can either make use of the continuous drainage mode or the bucket. The bucket will hold 21 pints of water and the unit will automatically switch off and alert you to the fact it needs emptying (eliminating the problem with overflows). You also have the benefit of a visible water level indicator located to the front of the dehumidifier.

Another great feature that many other brands cannot offer is that once the desired humidity level has been reached both the compressor and fan will switch off, which saves on energy. Further savings can be made on electric bills due to the energy star rating awarded to this model.

What We Liked

  • Low Temperature Operation
    When operating at low temperatures the KSTDA70A will automatically go into a defrost mode when the coils start to freeze, ensuring continuous operation.
  • Worry Free Drainage
    For continuous drainage, the KSTDA70 can be connected to any standard garden hose. The bucket holds 21 pints and the unit will light up and automatically shut-off when it’s full.
  • Energy Efficient
    Unlike many other models, this dehumidifier will switch both the compressor and fan off when the desired level has been reached. It also comes with an energy star rating for further savings on electric.
  • Portable
    This dehumidifier is lightweight and fitted with 4 casters so it can easily be moved room to room or lifted to another floor.

What We Didn't Like

  • P1 Error
    Many consumers have complained about the unit displaying a “P1” error and cannot find out what this means. This is in fact not an error. It means the unit has detected frost and is about to deal with the problem.
  • Cheap Construction
    The overall unit does have a very plastic feel to it, however the parts within appear to be pretty sturdy.


Keystone has done a decent job with the KSTAD70A. They have managed to produce a compact unit that has the ability to remove large amounts of moisture from the air. The price tag is not something that will shock either. It has many features that other brands don’t offer at this price level, however it is worth noting it’s not manufactured in the USA and the accompanying manual could be more self-explanatory.
