Mitsubishi Electric – NZ’s Best Dehumidifiers

Winter is not just about keeping our homes warm, it’s about keeping them dry. New Zealand winters are notoriously damp, and even well-insulated homes can suffer from high humidity levels. Indeed, keeping warm air trapped inside a dwelling can even acerbate problems caused by moisture build-up if poor ventilation is also a factor.

As a result, mould can start to appear in cupboards and on walls and soft furnishings, and condensation can build-up on windows, dripping and pooling on sills. And while opening windows to allow adequate airflow can help, it’s of little use if humidity levels outside are also high.

While heat pumps’ dehumidifying settings can help, they often don’t have the reach to help in the spaces that need dry air the most, in bedrooms and cupboards away from main living areas. But that’s where a dehumidifier can help, as a portable and affordable way to combat the problems associated with high humidity.
However, given the range of different dehumidifiers on the market and their different price points, it can be hard to work out which brand offers the best consumer satisfaction and value for money. But that’s where Canstar Blue can help.

As part of our mission to inform consumers of the best NZ has to offer, each year Canstar Blue canvasses the opinions of New Zealanders who have bought a dehumidifier within 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 is rated across the following categories:

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

Coming out on top for the second year in a row is Mitsubishi Electric. The Japanese brand is the clear winner in this year’s award, as the only brand to earn our top 5-Star rating for Overall Satisfaction. Across the board, it earns similar top ratings for Performance and Reliability and Effectiveness, plus admirable 4-Star ratings in all other categories.

Three brands earn 4-Star Overall Satisfaction ratings: Goldair, DeLonghi and Panasonic. Although Goldair is the only other brand other than Mitsubishi Electric to earn multiple 5-Star ratings, for Performance and Reliability, Value for Money, Functionality and Effectiveness.

It’s worth noting that all brands except our winner are regarded as somewhat noisy, only scoring 3-Stars in that category. It’s interesting because nearly a quarter of our survey respondents (23%) say that they find the noise of their dehumidifier off-putting!

What Kiwis Want From Their Dehumidifiers

Unlike many other appliances in the home, a dehumidifier is pretty much a workhorse that you switch on and leave until the job is done. And this practical functionality is reflected in the key driver of satisfaction for dehumidifier owners. Performance and Reliability is quoted as the most important factor for almost half in our survey (43%).

Value for Money is most important for 18%, and Functionality for 14%. Despite the 23% who claim to be annoyed by the noise of their dehumidifier, surprisingly only 8% cite Quietness of Operation as the most important factor in their satisfaction with the choice of machine.

Overall, the main drivers of satisfaction are:

Find noise of dehumidifier off-putting: 23%

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. The outcomes reported are the results from customers who had purchased a dehumidifier in the past two years. In this case, 278 New Zealanders. Brands must have received at least 30 responses to be included. Results are comparative and it should be noted that brands receiving three stars have still achieved a satisfaction measure of at least six out of 10. Not all brands available in the market have been compared in this survey. The ratings table is first sorted by star ratings and then by mean overall satisfaction. A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criterion.
