How HEPA Air Purifiers Can Reduce Allergy Symptoms
Allergies and hayfever often starts with what’s floating in the air; pollen, dust, pet dander and mould spores. HEPA air purifiers remove these particles before they can trigger symptoms like sneezing, itchy eyes or congestion.
Our purifiers combine fine-particle capture (down to 0.01 microns) with high clean-air delivery (CADR), meaning they don’t just trap allergens, they actually clear the room air several times per hour.
You’ll see plenty of purifiers marketed as “anti-allergy” or “medical-grade”, often paired with claims about special technology: ionisers, plasma filters, pollen filters, or other buzzwords.
The truth is simpler: any purifier with a HEPA filter has the potential to be great for allergies and hayfever, if it also moves enough air through that filter.
That second part — airflow, or CADR (Clean Air Delivery Rate) — is what most marketing skips over. Without it, even the best HEPA filter can’t clean a whole room effectively.
All our purifiers are built around these two proven principles: 🧩 HEPA filtration to capture allergens like pollen, dust and pet dander, and 🌀 High CADR to cycle the air multiple times per hour.
No gimmicks. No exaggerated claims. Just clean air backed by data.

Perfect, Awesome Purifier
The Smart Air SA600 works like a charm. From the moment it was put on, the room felt fresher, lesser dampness and definitely much lesser dander flying around as we have cats. Definitely will invest in more units in the future. Highly recommended A++++
I have a mould sensitivity - which is the main reason for buying the air purifier and have noticed a real change in the air quality with the SA600 - where as I didn't with the previous purifier I had. Thanks!
We got the purifier for our son who has allergies. It is quiet enough to have it on 1 overnight and it doesn't disturb his sleep. We also use it in the lounge when we need to clear the air (dog/cooking). On 3 it clears the room pretty quickly. I like that it is simple and affordable.

Yes, it can help many people by removing airborne allergens such as pollen, dust, pet dander and mould spores. Cleaner air often means fewer triggers and more comfortable breathing, especially during hayfever season.
However, every person’s sensitivities and environment are different, so results can vary. An air purifier can’t remove allergens that settle on bedding, carpets or clothing, and it won’t stop outdoor pollen from entering through open doors or windows.
The best results come from using a HEPA purifier with high clean-air delivery (CADR), keeping windows closed during high-pollen times, and cleaning regularly to reduce settled allergens.
Most people notice fresher air within hours, and less sneezing or dust build-up within a few days of continuous use - especially when pollen levels are high.
