Why it matters
The KNKA Max 21 Dehumidifier is a portable dehumidifier with a 0.45 gallons bucket, rated for 1300 square feet and removing up to 21 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 stated 110 watts, running non-stop uses about 2.6 kWh a day; in practice the compressor cycles off once the room reaches the set humidity.
Its rated area of 1,300 square feet is one of the smallest ratings we cover: 18 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.
It qualifies for our list Best Dehumidifiers for Bedrooms and Apartments, where it is ranked against every model that meets the same rule.

Pros and cons
Pros
- 21 pints per day removal
- 0.45 gallons bucket
- Rated for 1300 square feet
Cons
- Needs regular cleaning to stay hygienic
Limitations to weigh
- Not stated on the KNKA Max 21 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.
