We’ve tested a range of dehumidifiers to see whether their marketing claims stack up.
Overall score breakdown
Our dehumidifiers test includes:
Water removal
We measure dehumidifier water removal rates over 24 hours across a range of temperatures and humidity levels typical of New Zealand conditions. We use the average to produce a water removal score, giving slightly more weight to the most challenging (coldest) conditions and less weight to the least challenging conditions.
Low temperature performance
We use the dehumidifier's water removal rate measured at 8°C and 90% relative humidity to issue a low temperature performance score.
Energy efficiency
We measure how much energy is used per unit of water removed to provide the dehumidifier’s energy efficiency score.
Ease of use
We assess each dehumidifier for ease of tank emptying, layout and readability of controls, clarity of instructions, cleaning and ease of moving.
Other
We calculate dehumidifier running costs based on 8 hours’ use a day. We record how much noise each dehumidifier makes. And we make a note of each dehumidifier’s features and specifications.
