How do ozone filters remove ozone?

Ozone is a strongly oxidizing and chemically active substance that can react with a wide range of inorganic (e.g., sulfides, cyanides) and organic (e.g., olefinic compounds, nucleoprotein systems) substances in oxidizing reactions.

In general, outdoor photochemical pollution products are the main source of indoor O3. The increasing severity of outdoor ozone pollution has brought the problem of indoor ozone pollution to a point where it cannot be ignored. It has been shown in the literature that, in the absence of an indoor source of dispersion, the indoor O3 concentration under moderate ventilation will be 20% to 30% of the outdoor concentration; 40% to 70% under stronger ventilation; and in the absence of an indoor source, the detected indoor O3 concentration will be up to 0.35mg/m3.

It is important to note that the ozone concentration in the air that people breathe is not harmful, even in small amounts, there are still potential hazards to human health, as shown by Michael Brauer and Jeffrey R. Brook. NAAQS (National Ambient Air Quality Standards): the 1-hour average concentration standard of 0.240 mg/m3 and the Canadian Air Quality Objective of 0.164 mg/m3, ozone concentrations can negatively affect lung function.

Therefore, as far as technical and economic conditions permit, minimizing the concentration of ozone in the air is the goal we should pursue. At present, the most important method of removing ozone is through theOzone filtersReducing ozone concentrations.
