With nearly 1 in 5 Australians suffering allergic rhinitis (hay fever) and the sale of hay fever medicines doubling as a result, it’s good to know that an intelligent air purifier can trap 99.97% of allergens down to 0.3 microns in size.
Simply using an air purifier can help prevent hay fever symptoms and reduce the need for expensive and invasive medicines such as nasal sprays and oral antihistamines, and they can be used in the home, at the office, in vehicles and even on aeroplanes.
Hay fever does occur throughout the year but peaks in October and November. ACT has the highest rate of allergic rhinitis (26%), followed by Tasmania (23%), South Australia, Victoria and Western Australia (all 21%), and NSW (19%). The lowest rates were in NT (12%) and Qld (17%).
Unlike many health conditions, allergic rhinitis is most common in the middle years of life: 15 to 59 years and is triggered by an allergic reaction.
Common triggers include house dust, animal fur, pollens, fungal spores and air pollutants.
Know your pollens

The highest standard of air purifiers use HEPA filters, which stands for High Efficiency Particulate Air, and designates that the filters are able to trap 99.97% of particles that are 0.3 microns or larger including various pollens and pollutants.
Dust mites are also a big trigger of allergic rhinitis. A high level of humidity indoors (more than 60% Relative Humidity) actually encourages the growth of dust mites, which can't survive in less than 50% RH. Therefore, to keep these creatures at bay, keep humidity levels to under 50%. A dehumidifier can help achieve this.
Five-step air purifier filtration process
When choosing an air purifier, ensure the unit combines three forms of efficient air purification technologies: HEPA filtration, UV light and negative ions.
Some air purifiers, such as those from Andatech, utilise a five-step filtration process to completely and efficiently filter and clean indoor air.
Starting with the pre-filter, large airborne articles are removed from the air. The HEPA air purifier filter then removes microscopic particles from the air, while the carbon filter removes undesirable odours and VOCs (Volatile Organic Compounds).
The next step is the Titanium Dioxide filter and the UV lamp, which work hand-in-hand to break down harmful contaminants in the air and kill mould, bacteria and viruses. Finally, the air purifier releases negative ions into the air to help revitalise and refresh indoor air.
Even a home that’s regularly vacuumed will find the air purifier trapping not only dust, hair and dander, but also airborne allergens, bacteria, viruses, odours and harmful chemicals.
Additional features such as negative ionisers, UVC lamps and improved filters ensure clean, healthy air anywhere and anytime.
In addition to an air purifier, another important step in having a healthy home and minimal indoor allergens, is to check heating and air conditioning units regularly. Ideally, they should be cleaned and serviced every six months. Gas appliances and fireplaces should be vented outside and regularly maintained as well.
Hay fever stopped
Jamie, who started using an air purifier, runs a small business in tandem with a commercial kitchen and said, “I noticed that the kitchen odours were substantially less when leaving the filter running on [the] lowest setting. The staff were unaware I had implemented the filter, but hay fever in the office literally stopped the day I put it in.”
Bryan used an Andatech air purifier and said, “On the first night [after purchasing it and] running the filter for four hours I had one of my best night sleeps in a long time.”
