Sizes are matched to keep around three air changes an hour at a comfortable noise level for each setting. Bedrooms stay under 30 dB for sleep; living areas can run louder by day for extra airflow.

Even bigger, or a large quiet bedroom?

The Blast range carries the same HEPA and high-CADR approach into the largest rooms. The Blast Mk II also runs at just 29 dB on low, the quietest option we make for a big bedroom where overnight silence matters.

How HEPA purifiers actually help with allergies

Allergies and hayfever usually start with what's floating in the air: pollen, dust, pet dander and mould spores. A HEPA filter traps those particles before they reach you. But trapping is only half the job.

What decides whether your whole room gets cleaner is airflow, measured as CADR (Clean Air Delivery Rate): how much filtered air the unit actually delivers each hour. Our purifiers pair genuine HEPA media with high CADR, so the air cycles through the filter several times an hour rather than just the bit sitting near the machine.

That is the difference between a filter that looks good on a spec sheet and one that keeps a real room comfortable through pollen season.

An air purifier helps with

  • Airborne pollen, dust, pet dander and mould spores
  • Fewer triggers, so often less sneezing, itchy eyes and congestion
  • Cleaner air overnight in a closed bedroom
  • Cooking and pet smells, when fitted with a carbon filter

It won't

  • Remove allergens already settled in bedding, carpet or clothing
  • Stop fresh pollen blowing in through open windows or doors
  • Cure a medical condition. It's one helpful layer alongside cleaning and ventilation

The truth about "allergy" air purifiers

You'll see plenty of purifiers sold as "anti-allergy" or "medical-grade", usually paired with claims about special technology: ionisers, plasma filters, pollen filters and other buzzwords.

The truth is simpler. Any purifier with a genuine HEPA filter can be great for allergies and hayfever, as long as it also moves enough air through that filter. That second part, the airflow, is what most marketing skips over. Without it, even the best HEPA filter can't clean a whole room.

HEPA filtration to capture allergens like pollen, dust and pet dander.

High CADR to cycle the room's air several times an hour.

Every unit we sell is built around those two proven principles. No gimmicks, no exaggerated claims, just clean air backed by data. If you want the detail on filter grades, we wrote about H13 HEPA and what the numbers really mean.

What Kiwi allergy households say

★★★★★

Affordable and powerful

We got the purifier for our son who has allergies. It's quiet enough to have on overnight and it doesn't disturb his sleep. We also use it in the lounge to clear the air after the dog or cooking. On high it clears the room pretty quickly.

Perfect for our cats

The SA600 works like a charm. From the moment it was on, the room felt fresher, less dampness and much less dander flying around as we have cats. Will invest in more units in the future. Highly recommended.

Perfect for mould sensitivity

I have a mould sensitivity, which is the main reason for buying, and I've noticed a real change in the air quality with the SA600, where I didn't with the previous purifier I had. Thanks!

Our sinuses have improved

Great product and service. I'm so happy, and our sinuses have improved so much at night time since using our purifier.

Allergy purifier FAQs

Can an air purifier really help with allergies or hayfever?
Yes, for many people. By removing airborne allergens like pollen, dust, pet dander and mould spores, cleaner air often means fewer triggers and easier breathing, especially through hayfever season. Results vary from person to person. A purifier can't remove allergens that have settled into bedding, carpet or clothing, and it won't stop fresh pollen coming in through open windows. You'll get the best results from a HEPA unit with high CADR, kept running with windows closed when pollen is high, alongside regular cleaning.
How quickly will I notice a difference?
Most people notice fresher air within a few hours, and less sneezing or dust build-up within a few days of running it continuously, particularly when pollen levels are high.
How much is delivery and how long does it take?
Delivery is free across New Zealand on orders over $100. Orders ship from Christchurch on weekdays and usually arrive within 1 to 2 business days, with rural addresses adding another 1 to 2 days. The Blast and Blast Mini can take an extra 2 to 3 days. You'll get tracking as soon as your order is dispatched.
Are replacement filters easy to get?
Yes. We hold all filters in stock here in New Zealand, so you can reorder anytime from the site and have them within a couple of days.
What if I need help or something goes wrong?
You can reach our Christchurch team anytime. We offer quick, friendly support and a 1 year NZ warranty on every purifier, handled directly with no overseas wait times.
