Why it matters
The KNKA Max 34 Dehumidifier is a portable dehumidifier with a 3 liters bucket, rated for 2500 square feet and removing up to 34 pints per day a day.
Aim for 40 to 60 percent relative humidity indoors: drier air irritates airways and skin, wetter air feeds dust mites and mold.
The listing names a drain-hose connection.
A drain hose lets it run without emptying a bucket, as long as the hose runs downhill to a floor drain.
At its full rating of about 34 pints a day, a 6-pint bucket would fill in roughly 4 hours, so in a damp basement plan on a hose or pump rather than emptying it by hand.
At its stated 230 watts, running non-stop uses about 5.5 kWh a day; in practice the compressor cycles off once the room reaches the set humidity.
Its rated area of 2,500 square feet is below the middle of the range we cover: 42 of the 99 dehumidifiers with a stated figure come in lower, and the range runs from 110 square feet to 7,500 square feet.
Price-wise it sat in the cheapest third of the 52 portable models we cover when we checked; the button shows today's price.

Pros and cons
Pros
- 34 pints per day removal
- 3 liters bucket
- Rated for 2500 square feet
Cons
- Needs regular cleaning to stay hygienic
Limitations to weigh
- Not stated on the KNKA Max 34 Dehumidifier listing: airflow. Ask the seller or check the manual before relying on it.
- Pints-per-day figures depend on the test conditions; since 2019 the US test uses cooler, drier air, so newer ratings look smaller than older ones for the same machine.
