Understanding Safety with OZONO OZPro
If you’ve ever noticed a faint, fresh smell while doing your laundry with the OZONO OZPro, you’re not alone — and it’s completely normal. In fact, that light ozone scent is simply a sign that your device is doing exactly what it’s designed to do: producing powerful, chemical-free cleaning water.
Here’s a quick, customer-friendly guide to help explain why OZONO OZPro is safe, and effective — according to Australian safety standards.
Why You Might Smell Ozone

Ozone has a very distinct scent — often described as “fresh,” like the air after a thunderstorm. Humans are incredibly sensitive to it and can detect even trace levels as low as 0.01 ppm, long before it reaches any amount that could be harmful.
Aqueous Ozone vs. Airborne Ozone: What’s the Difference?
The OZONO OZPro creates aqueous ozone – ozone dissolved in water – at a safe concentration of 0.5–1.0 mg/L. This form is incredibly effective for cleaning and sanitising, yet breaks down rapidly back into pure oxygen and water.
During a laundry cycle, a tiny amount of ozone gas may momentarily escape when the machine drains or spins, but estimated levels stay well below 0.05 ppm — far below international safety limits.

What Australia Says: Safety Standards Down Under
Australia has specific exposure standards and ambient air quality measures to ensure safety:
- The peak limitation occupational exposure standard for ozone is 0.1 ppm. (WorkSafe Victoria)
- Under the Safe Work Australia guidelines, ozone is listed with a peak limit of 0.1 ppm (≈ 0.2 mg/m³) for short-term exposure. (WorkSafe Victoria)
- For ambient air quality, the National Environment Protection (Ambient Air Quality) Measure (NEPM) for ozone is 0.065 ppm for an 8-hour period. (Queensland Government)
Your laundry environment with OZONO OZPro will be operating well below all these thresholds.
Rest assured
A light ozone smell is actually a positive sign: it means the OZONO OZPro is generating active, chemical-free aqueous ozone.
Here are some helpful user tips:
- Keep laundry rooms lightly ventilated.
- If you’re sensitive to smells, just wait 2–3 minutes after the cycle finishes before opening the machine.
- Reminder: ozone leaves zero chemical residue — it breaks down into oxygen and water naturally.
Conclusion
With the OZONO OZPro operating at 0.5–1.0 mg/L aqueous ozone, you’re well within safety thresholds not only internationally, but specifically for Australia. The faint ozone scent is a normal, harmless indicator that your system is working perfectly — delivering chemical-free, residue-free cleaning at its best.
Chemical-free. Residue-free. Hassle-free.
