Mitsubishi Electric – NZ’s Best Dehumidifiers

From modern leaky homes, to poorly insulated, older damp dwellings – NZ doesn’t have a very good record when it comes to moisture problems and houses. But even in modern, warm homes, dampness can still be a problem.

This is especially true in winter, when it’s often difficult to give a home a good airing. Shut-up rooms can quickly start smelling damp and fusty, and fogged-up windows leave pools of water lying on sills. Not only can dampness damage property and possessions, it’s terrible for our health and wellbeing, too.

While expensive air-conditioning systems are one solution. Portable dehumidifiers are a more affordable choice. In Canstar Blue’s latest research, nearly half of Kiwis (48%) regard their dehumidifier as an essential household item. And the same number believer that it protects them and their family from ill-health.

But given the wide range of dehumidifiers to choose from, it’s hard to judge which brands offer the best customer satisfaction. So as part of our mission to inform consumers of the best NZ has to offer, Canstar Blue canvassed the opinions of 278 New Zealanders who had purchased a dehumidifier in the past two years, across a range of categories, to measure and track their satisfaction.

To decide which dehumidifier offers the best level of customer satisfaction, each was rated across the following categories:

  • Appearance and Design
  • Effectiveness
  • Functionality
  • Performance and Reliability
  • Quietness
  • Value for Money

Coming out on top is Mitsubishi Electric. The Japanese brand is the clear winner in this year’s award. An outstanding performer, Mitsubishi Electric blitzes its competition with 5-Star awards in every category, including for Overall Satisfaction.

Behind Mitsubishi Electric, Goldair and DeLonghi also rate strongly, both with 4-Star Overall Satisfaction ratings.

There are a few reasons why a dehumidifier can be a useful appliance in NZ home:

  • Dampness: Dehumidifiers help eliminate dampness, a perennial problems in many NZ homes
  • Mould: Dehumidifiers combat mould and mildew. A damp home creates the perfect conditions for mould and mildew to form, but they struggle to form in less than 50% humidity
  • Dust mites: These are invisible occupants of your bedspreads, mattresses, curtains, carpets, etc. While they can live in dry homes, they prefer damp conditions When they multiply, they can trigger allergic reactions
  • Musty smells: Musty smells are caused by the growth of mould and mildew
  • Health: A dry, warm home is a healthier home, for all family members
  • Condensation: Condensation usually appears in the form of foggy windows, and can lead to wood shrinking, damp patches on walls and peeling wallpaper

Don’t forget, as well as using a dehumidifier, it’s essential to get good airflow moving through your home. This can be achieved easily by opening your windows for around 20 minutes each day.

Refrigerant dehumidifier

Works by condensing moisture out of the air. Damp air is sucked into the dehumidifier and is cooled to below its dewpoint temperature using the same processes as a fridge. This causes condensation to drip into a water-holding pan, which can either be emptied manually, or automatically through a hose. These are the most common types of dehumidifiers. They work better in higher temperatures and at increased humidity levels, although can be noisier than desiccant dehumidifiers.

Desiccant dehumidifiers

The humid air moves over a rotating wheel made of a water-absorbing material. The dry air is blown back into the room, while the water-absorbing material is heated, causing it to release its water into a collection tray. Absorption models are more complicated in their design and can be less energy efficient. However, absorption dehumidifiers work better at lower temperatures, which make them a good option for use in colder climates.

Buying a dehumidifier:

  • The best models have a digital humidistat, which his like a thermostat for humidity
  • Check for literage, the amount of water the dehumidifier can remove from the air over 24 hours. The bigger the number, the better the machine
  • Look for a good Star Energy Rating – it will cost you less to run
  • Don’t buy a machine unless you’ve heard it running and are happy with its noise level

   Using a dehumidifier:

  • Wash air filters once a month to help the fan operate efficiently
  • Keep an eye on temperatures. Most dehumidifiers operate less efficiently when the temperature falls below 18C
  • Maintain good air-flow. Keep your dehumidifier away from the wall for good air circulation.

Canstar Blue surveyed 2581 New Zealand consumers across a range of categories to measure and track customer satisfaction, via ISO 26362 accredited research panels managed by Qualtrics.
