Smart Air SA700 Air Purifier

Yes. The SA700 comes with a 1-year manufacturer’s warranty, plus all the protections of the New Zealand Consumer Guarantees Act (CGA). The durable design means very few issues in practice, and our local support team is here to help if you ever need it.

Short answer: E11 for most people, H14 for specific needs. The E11 filters (included) capture at least 95% of particles per pass and allow maximum airflow: 720m³/h, covering up to 78m². Because the air passes through many times an hour, the room gets very clean very fast. The H14 filters capture 99.995% per pass, the highest HEPA grade, certified to EN1822 and used in hospitals, with a CADR of 490m³/h covering up to 60m². H14 makes sense for clinical settings, high-risk households, or anyone who wants maximum single-pass capture. Bonus: H14 filters also last longer, so their higher price roughly evens out over time. You can read more about why airflow matters as much as filter grade in our H13 HEPA guide.

Yes. With a CADR of up to 720m³/h, the SA700 removes airborne allergens like dust, pollen, mould spores and pet dander faster than anything else in our range. While results vary and we can't guarantee outcomes, consistently clean air makes a real difference for many asthma and allergy sufferers, and the SA700 has no ionisers or ozone, so it's safe for sensitive lungs.

Yes. HEPA filters are highly effective at capturing airborne viruses and bacteria, even particles smaller than 0.01 microns thanks to Brownian motion. The SA700's high air change rate is exactly what's recommended for reducing airborne transmission in shared spaces, which is why this style of purifier is popular in clinics and classrooms overseas.

The HEPA filters handle particles, but odours and VOCs are gases, and that's a job for activated carbon. The optional SA700 carbon filter pack adds 750g of granular activated carbon per side, 1.5kg in total, the most carbon of any purifier setup we sell. The carbon filters sit over the HEPA filters and can be added or removed any time.

Yes, with the optional bracket set. At 6.7kg the SA700 is light enough to mount safely on standard walls and ceilings. The right fixings depend on your wall type, so the bracket guide covers timber, masonry and ceilings, and we're happy to help you pick the right ones before you order. One practical note: the power cable is 1.8m, so plan your mounting position with a power point within reach. It's a good way to protect floor space and keep the unit out of reach in classrooms and waiting rooms.

No, and that's deliberate, the same philosophy as the rest of the Smart Air range. Built-in sensors are often inaccurate and switch units off while harmful particles are still in the air. We recommend running the SA700 whenever people are around, or continuously, which its 12W power draw makes genuinely affordable. For accurate monitoring, pair it with a dedicated air quality monitor.

At New Zealand's average price of $0.25/kWh, running the SA700 continuously costs around 7 cents a day, roughly $2.20 a month or $26 a year. That's running 24 hours a day, every day. For comparison, that's about the same annual power use as a Wi-Fi router

Perfectly. The SA700 has a simple physical switch, so when power is restored it picks up exactly where it left off. Set a schedule on a smart plug and you've effectively added a timer mode for about $20.

Orders ship promptly from our Christchurch warehouse, sent out every weekday afternoon. South Island is usually next business day, with 2 business days for North Island (slightly longer for rural addresses).

Almost nothing. The one tool worth having on hand is a Phillips screwdriver, used to adjust the small metal tabs that hold the filters in place. It's handy for making sure the filters are seated and secured correctly, and you'll want it later when it's time to replace them. We don't supply one, but it's the only thing you'll need. After that, plug into a standard wall socket and it runs at full output.
