Choosing the right dehumidifier for you
A dehumidifier isn't an exciting, interactive home product. You turn it on, walk away and expect it to perform its job.
Therefore, it's no surprise that Performance & Reliability is the most important factor cited by nearly half (45%) of the consumers in our survey when rating their choice of dehumidifier.
Functionality is also a key concern, raised by a quarter (26%) of respondents, which covers the useful functions offered by many dehumidifier units, such as laundry features, timers and air-purification modes.
Here's the full rundown of what those in our survey said they considered most when rating their dehumidifiers:
- Performance & Reliability: 45%
- Functionality: 26%
- Appearance & Design: 15%
- Value for Money: 14%
What a dehumidifier can prevent in your home
A dehumidifier can be an essential appliance in the home, and can help prevent or alleviate:
- Dampness: a perennial problem in many NZ homes
- Mould: 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. And when they multiply, they can trigger allergic reactions
- Musty smells: these can be caused by the growth of mould and mildew
- Condensation: foggy windows can damage wooden window frames and lead to damp patches on walls and peeling wallpaper
Types of dehumidifier
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.
Tips for buying and using a dehumidifier
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 more effective 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 18°C
- Maintain good air-flow. Keep your dehumidifier away from the wall for good air circulation
