Observing ozone damage from the perspective of dividing concentration into two parts
The consensus among experts is that discussing damage without considering the dosage is playing rogue tricks. Just like alcohol, excessive consumption can damage the body, but we cannot deny the benefits it brings when consumed in moderation. The key issue is the concentration index, not ozone itself. The three identities of ozone (Wuwei Master and Destroyer) correspond to three different concentration values. Ozone above a stable value is a Destroyer, while ozone below a stable value is Wuwei Master.
In China, due to different application intentions and scenarios, there are three sets of ozone standards, namely "Ozone Industrial Hygiene", "Environmental Air Quality Standards", and "Indoor Air Quality Standards". Different standards lead to different measurement units, which is also one of the reasons why ozone has always been "mysterious". For ease of understanding, in the following text, when it comes to ozone values, ppb units are consistently used.
The stable value of ozone concentration for air purifiers is 50ppb, and we must remember this number. When purchasing non consumable air purifiers, we must ask the merchant to provide an ozone testing statement and carefully and clearly observe this data. Nowadays, non consumable air purifiers on the market can generally control the ozone concentration at 50ppb. The difference is who can control it lower, such as in single digits, so don't worry, just buy it.
Let's talk about the story of 50ppb. Does 50ppb refer to an air purifier operating at 30m? Open the sealed room for 24 hours, and the high cumulative concentration must not exceed 50ppb to be considered qualified.
What is cumulative concentration: Ozone will self differentiate. For example, there is a water tank with an inlet and outlet. The inlet is the amount of ozone produced by the air purifier, and the outlet is the amount of ozone that self differentiates. Accumulated concentration refers to the water stored in a pool.
For example, for an air purifier, its ozone detection statement shows that the ozone concentration is 5ppb. If X3 is run in the bedroom all night, the indoor ozone concentration will only be 5ppb, not to mention that the air entering through the window gap will dilute the concentration. In reality, the ozone concentration should be even lower, as low as dust, invisible and inaudible.
