Abstract：
 The present invention relates to method and apparatus for eliminating organic pollutant air in building. The method includes the following steps: 1. making organic pollutant air flow through high humidity material layer inside one sealed device; 2. injecting O3 with one ozone generator; 3. irradiating the high humidity material layer with ultraviolet ray to generate free hydroxyl radical; and 4. producing oxidation reaction between the free hydroxyl radical and the organic pollutant to produce CO2, water or mineral salt, so as to eliminate the organic pollutant. The present invention has simple structure, convenient use, high purifying efficiency, stable effect, adjustable purifying capacity, low cost and other advantages, and may be used widely in fields needing to eliminating organic pollutant in the air.
