Next step to achieving better indoor air quality

Based on the development in some foreign countries, forecasts the next step to achieving better IAQ is biocontamination control. Biocontamination, instead of the contamination caused by building and decoration materials, will be one of the major indoor microcontamination sources in China. Biocontamination is the result of contaminated HVAC systems and improper conditioned environments. Puts forward the concept of residual humidity pollution and presents relevant studies and humidity control measures.
