Customer Reviews on Keystone KSTAD70B

I have read reviews for the Keystone KSTAD79B from customers and summarised them below.

The Pros

Customers have mentioned that the location of the filter on the top allow for ease of access for cleaning. Cleaning of the filters is crucial in the removal of mould spores or bacteria to lower the risk of possible respiratory disease. The castor wheels allowing for transportation, plug and play installation are other mentioned pros in the design.

Effectiveness in removing moisture; a customer who installed this Keystone dehumidifier in his basement noted a decrease in moisture content from 70% to 55% in 4 hours. The ease of programming a dehumidifying schedule was also mentioned by customers.

The in-built clean filter alert and auto-restart option are other mentioned desirable aspects of this dehumidifier. 

The Cons

There was some feedback about the design and durability of the water bucket, ranging from difficulty in removal for emptying, bad fit for the slot, to cheap material. Another point raised include the level of operational noise where reviews were generally mixed, with both positive and negative feedback. 

The supplied adaptor for attachment of a regular garden hose for draining were mentioned to be flimsy and not secure due to its plastic assembly. One customer has mentioned that it can be solved by attaching it to the connector on the bucket directly.
