The best dehumidifiers we’ve tested can extract over 6L of moisture from the air in 24 hours – one can collect 8.3L. But the worst extract only about 2L in the same amount of time and even less at low temperatures.

You could easily buy a poor performing dehumidifier if you choose one based on manufacturer claims. We’ve found the amount of moisture dehumidifiers can collect is, on average, only about 30% of the claimed maximum water extraction rate.

That’s because manufacturers test their dehumidifiers at 30°C and 80% relative humidity – conditions very different to a typical New Zealand home.

At Consumer NZ, we test all dehumidifiers at a range of realistic temperatures and humidity levels.
