Independently Tested. 49x below the CARB Limit.🔬
The Airwash Pro was tested by an independent third-party laboratory. The ozone output came back at 0.002 mg/m³ - 49 times below the emission limit set by the California Air Resources Board (CARB), the strictest air purifier standard in the world.
Here's what that number means in practice. CARB requires every air cleaning device sold in California to stay below an ozone emission concentration of 0.050 parts per million, which is approximately 0.098 mg/m³. Thousands of air purifiers you'd find in any home pass under that bar. Every air purifier legally sold in California must meet this standard.
The Airwash is 49 times below that limit.
0.002 mg/m³ is a measurement of maximum concentration in the air itself, meaning how much ozone each cubic meter of air around the device contains. It's not a production rate, so there's no "per second" or "per hour." It works like a thermometer: when a room is 72 degrees, it isn't 72 degrees per hour.
Why the Reading is So Low.
It comes down to power. Airwash runs on less than 1 watt, which is less than a phone charger draws sitting idle on your nightstand.
Airwash is a small device, only requiring sufficient energy to ionize particles in your personal breathing zone. Not a whole room.
Producing ozone at high levels requires serious energy. Industrial ozone generators are machines built to flood empty rooms with concentrated ozone for commercial disinfection, and they pull anywhere from 50 to over 200 watts.
At 1 watt, the energy to produce harmful ozone levels simply does not exist. It isn't a setting that could drift or a filter that could wear out. It's a hard physical ceiling on what the device can ever emit, on day one and on day one thousand.
What 0.002 mg/m³ feels like
Nothing. That's the honest answer.
Ozone is already a normal part of the air you breathe. It's outdoors every day, and on a sunny afternoon the air outside your window contains more ozone than this device produces. The clean, sharp smell after a thunderstorm is ozone at concentrations far higher than anything Airwash emits. The output is so low that most consumer grade ozone meters can't even register it. Detecting it at all requires laboratory equipment.
You will never smell it, sense it, or notice it.
If You’ve Heard That Ozone Air Purifiers Are Dangerous.
You've heard right. Ozone-generating air purifiers produce ozone deliberately, at high concentrations, as their entire method of operation. The EPA warns against them and CARB keeps a public list of hazardous ones sold as air purifiers.
Airwash is not one of those devices. It doesn't generate ozone as its function, and it couldn't if it tried. It's a negative ion device running on 1 watt of power, a hard physical ceiling that makes high ozone output impossible regardless of settings, age, or wear.
CARB enforces the strictest ozone emission standard in the world - to be sold legally, an air cleaning device must stay below 0.050 parts per million. An independent laboratory measured Airwash pro at 0.002 mg/m³. That isn't just passing the strictest standard in the world. It's 49 times below it. At 0.002 mg/m³, Airwash produces a dose so small that it is practically unmeasurable.
