Smart Air SA600 Air Purifier

Yes! While we can't guarantee it will help everyone in every situation, the combination of the HEPA filters and the very high clean air output of the SA600 is very potent! It means any pollutants in the air which may trigger Asthma or Allergies will be quickly removed.

Common triggers including dust, mould spores, pet dander and pollen will all be captured by the HEPA filter.

No, the SA600 has been designed for simplicity and affordability. While it may seem logical to want your air purifier to activate when it senses poor air quality. Many manufacturers unfortunately add on a cheap inaccurate air quality sensor and then charge you more for what should be a simple product! This means the air purifier may allow unhealthy levels of pollutants in the air.

Instead we recommend running the SA600 whenever people are around, or even 24/7 - our air purifiers are designed to last! You can also purchase an accurate standalone air quality monitor from us to better understand your air and how effective the air purifier is.

Like many other air purifiers, the filter replacement light comes on after a set number of hours of use. In New Zealand conditions, your filter will typically last longer. See below to determine when to replace the filter.

To reset the filter reminder, hold the button under the filter light for 4 seconds.

For the HEPA Filter:
As the filter slowly fills up with pollutants, you'll see it get discoloured from it's original white. Often it will appear grey or black. If you notice the SA600 doesn't seem to be providing as much clean air as before, have a look at the HEPA filter. We provide an estimate of a 19 month lifespan based on 8 hours use per day in NZ.

Carbon Filter:
Because it's very hard to estimate their lifespan, we recommend checking regularly by conducting the smell test. If it has an acidic/metallic smell then the filter is saturated and can no longer absorb VOCs and Odours.

Yes, the HEPA filter on The SA600 can indeed filter out nanoparticles! While some brands claim only their specific air purifiers can capture nanoparticles, this isn't true. Every proper HEPA filter, such as the H13-rated SA600 filter, can effectively remove nanoparticles.

You often see HEPA filters rated for 99.97% efficiency against 0.3-micron particles, which are much larger than nanoparticles. Interestingly, 0.3 microns is chosen as the test size because it's actually more challenging to filter than smaller particles due to their size and behavior. Nanoparticles, which can be as small as 0.001 microns, move in random zigzag patterns (Brownian Motion), making them more likely to get trapped in the filter fibers.

So, even though 0.3 microns are larger, HEPA filters can efficiently capture nanoparticles due to this Brownian Motion. This means HEPA filters are highly effective at removing these tiny particles from the air, ensuring nearly 100% filtration.

Yes, the SA600 operates with air coming from both sides. So please unwrap the filters on both the front and back of the unit.

Yes! it’s designed for simple, “set-and-forget” operation. You pick your fan speed using the fan button and the unit remembers that setting. Whenever power is restored - whether by flipping a smart plug, a timer plug or a wall switch, it automatically comes back on at the last speed you used.

Because there’s no built-in Wi-Fi or app required for on/off control, you can integrate it into any home-automation routine or schedule without extra setup. Just power it on and off as needed, and let your smart plug handle the rest.

The Pre Filters should be cleaned at least once a month with a dry and clean cloth.
