De’Longhi is a breath of fresh air in dehumidifier & air purifier ratings
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 actually cause excess moisture in our homes, increasing the risks of growing mold spores or developing mold-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 if you suffer from asthma or allergies.
To help you breathe a sigh of relief, we tried seeing what works by asking almost 500 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 & design, reliability, value for money and overall satisfaction. Those that received at least 30 responses are compared in this year’s report.
De’Longhi took the lead in our first-ever dehumidifier & air purifier ratings, earning a five-star review for overall satisfaction and most other categories!

How do you know if your home is too humid?
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:
- Musty smells
- Dark spots on walls
- Peeling paint
- Allergies and respiratory problems
Our research found that a third (30%) of people who took part in our survey use their air treatment appliance daily during summer. About two in five survey respondents (38%) bought a dehumidifier or air purifier to help with allergies or other medical conditions. Meanwhile, one in four (26%) said they purchased the product to make the air feel nicer.
What is a dehumidifier?
A dehumidifier aims to lower humidity levels in the air by collecting excess moisture. This helps minimise the risk of growing mold, mildew and allergens in the home, as well as to create a much more comfortable living environment, especially in summer.
What is an air purifier?
An air purifier is designed to improve 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.
Dehumidifiers & Air Purifiers Compared
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, 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.

To tackle the dangers of mold 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.

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.

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.

Should I get a dehumidifier?
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.
Should I get an air purifier?
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.
