FAQs
You'll see we list this on each product page under the section "Filter Lifespans & Replacements." Due to the large surface area of the HEPA filters used, they're at the higher end of replacement intervals in NZ.

Yes, our purifiers equipped with HEPA filters can capture nanoparticles.
HEPA filters are often rated 99.97% at 0.3 microns, but that’s just the test size. Nanoparticles (down to 0.001 microns) move randomly (Brownian motion), which actually makes them easier for HEPA filters to trap.
In short: a proper HEPA filter doesn’t just stop dust and pollen - it also captures ultrafine nanoparticles, keeping your air truly clean.

Ionisers can artificially inflate CADR readings, making performance claims look better than they are. More importantly, they can create ozone - a harmful pollutant. Our purifiers are 100% ioniser-free because clean air means removing pollutants, not adding new ones.
Yes. HEPA filters like ours are highly effective at capturing airborne viruses - including Covid - as well as bacteria. By trapping these particles, purifiers help reduce the risk of them staying suspended in the air where you breathe.
It depends on your rooms and layout. One purifier per main room is ideal, but in many cases a single unit in the living area plus one in the bedroom gives great results. For open-plan spaces or multiple rooms, check out our guide on how many purifiers you need.
We specialise in air purifiers - not hundreds of unrelated products. That means better product knowledge, fair pricing without gimmick “sales,” and filters always in stock. Plus, you’ll get local support from people who actually use the purifiers we sell.
Because you’re not paying for inflated mark-ups, glossy ads or gimmick features. Smart Air (manufacturer of our products) was founded to prove clean air doesn’t need to be expensive. By keeping designs simple and data-backed, we deliver top performance at honest prices.
We keep prices always low, rather than raising them to offer bigger 'discounts'.
Orders ship from Christchurch daily during the week and usually arrive within 2 business days. You'll get tracking details as soon as your order is dispatched. Blast & Blast Mini can take another 2-3 days.
Yes - every purifier has a standard 1-year manufacturer’s warranty, plus you’re covered under the NZ Consumer Guarantees Act. With simple, robust designs, issues are rare. And if something does go wrong, we’ll sort it quickly and locally.
No - and that’s deliberate. Cheap built-in sensors are often inaccurate and can switch the purifier off while the air is still unsafe. We recommend running your purifier whenever people are in the room. For accurate tracking, pair it with a dedicated air quality monitor.
