Ozone O3 is an inorganic molecule
and exists almost everywhere around us. Ozone is a powerful oxidant
(far more so than dioxygen
) and has many industrial and consumer applications related to oxidation. In the nature, it helps cleaning and sterilizing our living environment. More you can read in Wikipedia.
The effectiveness and influence of ozone is well-known. Here you have an overview:
– Harmful to airway-sensitive people (asthma, allergy, COPD,…): > 0.1 ppm (100 ppb) x longer than 6 hours
– Outdoor under sunlight in summer time: > 0.1ppm (100 ppb). This is the outdoor air quality index of O3 as the threshold value.
– Outdoor in cloudy or rainy day time: 50~100 ppb.
When the window is open to let outdoor natural O3 flow in, the indoor O3 concentration would be around 50~60 ppb. This is also the reason why “open window” is good for health, due to natural O3 from outdoor to sanitize the indoors. Therefore, any electronics to pass the safety certificate, need to comply the O3 emission < 50 ppb
. This means artificial O3 emission needs to be below 60ppb naturally. Our portable sanitizer Smini
and other models with APCO inside have complied this standard. Read the Radiation and Toxicity test report
for more infomation.
