The Best Air Purifiers for Asthma in New Zealand

With New Zealand standing as one of the global hotspots for asthma, affecting a sizable chunk of one in eight Kiwis1, the significance of managing this respiratory condition cannot be overstated. Given the daily hurdles asthma can pose, you might find yourself pondering, "Can an air purifier help with my asthma?"

Well, here's a breath of fresh air - they absolutely can! Venturing into the realm of improved indoor air quality is a key stride towards reigning in asthma symptoms, and that’s precisely where the stellar air purifiers at Snap Air shine.

Key Points Summary:

  • Improving indoor air quality is crucial in managing asthma symptoms.
  • Common indoor asthma triggers include dust mites, pollen, mould spores, pet dander, and tobacco smoke.
  • Air purifiers help by filtering out harmful particles and circulating clean air.
  • When selecting an air purifier for asthma, prioritise HEPA filters and a high Clean Air Delivery Rate (CADR), while avoiding ionisers.
  • Many manufacturers invest heavily in marketing their products as the ultimate solution for asthma sufferers. However, cutting through the spin reveals that a genuine HEPA filter is crucial, provided the purifier doesn't generate negative ions or house an ioniser.

Unveiling Common Asthma Triggers

Every one of us has our own set of triggers when it comes to asthma, but there are some indoor offenders that often stir the pot:

  • Dust mites
  • Pollen
  • Mould spores
  • Pet dander
  • Tobacco smoke

Keeping the indoors spick and span is non-negotiable for folks with asthma, making air purifiers a handy ally.

Air Purifiers: Your Ally in Asthma Management

Think of air purifiers as your personal indoor air quality custodians. They pull in the room air, trap the harmful particles that could trigger your asthma, and send back clean air for you to breathe easy. By diminishing the asthma triggers in your space, these silent guardians cut down the chances of an unexpected asthma ambush.

Selecting an Asthma-Friendly Air Purifier: What to Look For

When you’re on the hunt for an air purifier to wage war against asthma, there are a few key features that should top your checklist:

  1. HEPA Filters: High Efficiency Particulate Air (HEPA) filters can capture upwards of 99% of airborne particles as small as 0.3 microns, including many common asthma triggers. At Snap Air, all our air purifiers come with HEPA filters.
  2. Powerful Performance: The Clean Air Delivery Rate (CADR) reflects how swiftly an air purifier can cleanse the air in a given space. A higher CADR translates to effective purification in larger rooms.
  3. Avoid Ionisers/Negative Ion Generators: These can produce ozone, a respiratory irritant, as a byproduct. The US Environmental Protection Agency (EPA) cautions that even at low levels, ozone can cause chest pain, coughing, shortness of breath, and throat irritation2. And here’s a heads up—some models sold here in New Zealand under fancy names like plasma generators carry these features. It's a wise move to steer clear of them.
