Humidity doesn’t just make rooms uncomfortable and stuffy. Humidity from water vapour in the air or produced by vented dryers and other household appliances can cause excess moisture in our homes, increasing the risks of growing mould spores or developing mould-related allergies. It can also lead to musty smells and form rust and dark spots on the walls.
And if the humidity wasn’t enough ─ pollen, dust mites, and bacteria also often circle around rooms and affect the quality of the air we breathe. All of this can be harmful to our health, especially for asthma and allergy sufferers.
To help you breathe a sigh of relief, we tried seeing what works by asking more than 300 Australian consumers for their feedback on the dehumidifier(s) or air purifier(s) they purchased and used in the last three years. Respondents rated brands on effectiveness, functionality, quietness while operating, appearance and design, reliability, value for money and overall satisfaction. Those that received at least 30 responses are compared in this year’s report.
Philips took the lead in our latest dehumidifier & air purifier ratings, earning a five-star review for overall satisfaction and most other categories!
Here are the best dehumidifier and air purifier brands in Australia, as rated by consumers in Canstar Blue’s latest review:
Philips was rated best for effectiveness, functionality, quietness while operating, reliability, value for money and overall satisfaction. Runner-up De’Longhi was the top pick for appearance and design and also scored top marks for low noise, before ending on four stars for overall satisfaction, alongside Dyson. Meanwhile, Breville and Kmart rounded up the results on three stars overall.
While experiencing humidity is normal, health problems can arise when there’s too much humidity in the home. Here are some signs to look out for:
Our research found that nearly a third (28%) of people who took part in our survey use their air treatment appliance every day during summer. Almost two in five survey respondents (36%) bought a dehumidifier or air purifier to help with allergies or other medical conditions. Meanwhile, a third (31%) said they purchased the product to make the air feel nicer.
A dehumidifier aims to lower humidity levels in the air by collecting excess moisture. This helps minimise the risk of growing mould, mildew and allergens in the home, as well as to create a much more comfortable living environment, especially in summer.
An air purifier is designed to improve the overall air quality in the home by eliminating small harmful particles from the air, such as fine dust, pollen and bacteria. Keep in mind that air purifiers contain different types of filters which vary in size and efficiency between models. Filters available include high-efficiency particulate air (HEPA), carbon, ionic, and UV lighting.
Philips sells multiple types of air treatment products, including air purifiers and humidifiers as well as filters and accessories. The range has a mid to high price tag, with models costing between $129 and $1,399. A Money Back Guarantee option is also available for specific models, including the Philips Series 1000i Air Purifier and the Philips Dehumidifier Series 5000.
Most Philips air purifiers are claimed to eliminate up to 99.99% of pollen allergens. Certain models, such as the Philips Series 3000 Air Purifier, contain a Special Allergen mode which apparently increases its cleaning performance when it detects a change in air quality.
Some models you can expect to see include:
Philips was rated five stars for effectiveness, functionality, quietness while operating, reliability, value for money and overall satisfaction. It got four stars for appearance and design.
Clearly, the smell of fresh coffee isn’t the only thing De’Longhi is leaving around the home. The brand also offers several dehumidifier models in the AriaDry range, designed to keep a healthy level of humidity around the home by absorbing any excess moisture from the air.
Aside from purifying air, De’Longhi’s range includes a few useful features including a laundry function which helps to supposedly dry clothes faster, while some models also come with a PTC ceramic heating element that allows the appliance to dehumidify more air in a shorter amount of time, according to the brand.
The models currently available include:
De’Longhi scored five stars for appearance and design and quietness while operating, plus four stars for overall satisfaction and everywhere else.
Dyson’s high-end air treatment line includes three types of purifier fans. The different collections include the Dyson Purifier Hot+Cool Formaldehyde, Dyson Purifier Hot+Cool and Dyson Purifier Cool. These typically retail between $799 and $999.
For a year-round air purifier, Dyson’s Purifier Hot+Cool models can be used for both cooling and heating. Although you can find many of the same features between the different collections.
If you suffer from asthma or allergies, Dyson’s air purifiers are approved by the Sensitive Choice program. These purifier fans are claimed to eliminate up to 99.95% of allergens and pollutants. Plus, these models are designed to automatically detect airborne particles and gases, before diagnosing and reporting the information in real-time. Dyson Purifier Hot+Cool Formaldehyde models are also designed to sense and trap formaldehyde.
Available in different designs, Dyson‘s purifier models include:
Dyson achieved a solid four-star rating across the board, including for effectiveness, reliability, design, value for money, and overall satisfaction.
To tackle the dangers of mould and mildew, such as those created by everyday household appliances, Breville offers several dehumidifiers that each target different room types and sizes, as well as climates.
Each model is said to produce a fine, pure cold or warm mist that helps restore humidity levels. The brand claims this can relieve dry skin, eyes and sinus passages and ultimately help you breathe easier. The four-stage filtration system contained in each Breville dehumidifier is also said to help reduce allergens, dust, viruses and bacteria.
For an environmentally-friendly dehumidifier, Breville’s All Climate Dehumidifier uses silica dioxide crystals which supposedly absorb moisture more naturally.
Breville’s dehumidifier range currently includes:
Breville earned a four-star review for reliability and three stars everywhere else.
Kmart is a go-to place for budget-friendly appliances like air fryers and microwaves, so it makes sense consumers are also heading to the retailer for affordable air treatment products. When it comes to air purifiers, Kmart attempts to blow away shoppers with a range targeted at different household sizes and budgets.
Features are fairly similar across all models, with area coverage being the major difference. The small option is designed for rooms no bigger than 6m2, while the largest model is said to be suitable for spaces measuring up to 38m2. Kmart’s Medium Tower Air Purifier offers a middle-ground option. Priced at $99, this HEPA filter tower air purifier is claimed to remove contaminants and improve the indoor air quality of spaces measuring up to 7.2m2.
Other common features include three fan speeds (or four for the Large Family Air Purifier), and an hourly timer. Kmart’s air purifier range includes:
Kmart rounded up the scores on three stars for overall satisfaction and across the board.
The brands rated above aren’t the only options worth considering, so be sure to check out what other brands in the market have to offer in the air purification and dehumidification space.
If you’re looking for variety, Beurer offers a large range of air purifiers, air humidifiers and air dehumidifiers. Prices also cater to most budgets, typically starting from just under $100 and reaching up to the $800 mark. Accessories such as replacement filters are additionally available.
Many of Beurer’s air purifiers are claimed to filter out up to 99.95% of fine particles, such as bacteria, viruses, dust and pollen. This is apparently thanks to its three-layer filter system, which contains a prefilter, activated carbon filter and HEPA filter.
New models including the LR500 use Wi-Fi compatibility to give households greater control and access to their air purifier. This model also comes with a function that automatically adjusts its settings based on the air quality in the room.
Dehumidifiers are generally recommended for those who suffer from allergies. They’re also suitable for any households that regularly dry clothes indoors, or otherwise have high levels of condensation which ends up creating a moist or humid environment.
Air purifiers are said to be especially useful for homes that have higher levels of dust, pollen, smoke, and other allergens. They can also be helpful for allergy sufferers. Pet owners might similarly benefit from having an air purifier, especially with pet dander, hair and odours lying around. Plus, air purifiers are even said to help people achieve a better quality sleep.
