Type: article
Abstract: The paper aims to build an air purifier particle filter lifetime evaluation algorithm fit for outdoor PM2.5 low concentration. Current, GB/T 18801 standard gives the evaluation of particle filter lifetime base on outdoor PM2.5 concentrations based on CCM value of particle filter. But the formula that givens by GB/T 18801 only fit for outdoor PM2.5 concentrations that is higher than 58 ug/m^3. When outdoor PM2.5 concentrations is low than this value the result of filter lifetime will be negative value. However, in real case, outdoor PM2.5 concentration in most area is lower than 58 ug/m^3. Developing the particle filter lifetime evaluation algorithm fit for outdoor PM2.5 low concentrations situation is needed. The paper gives the new aspect of the calculation that considers low PM2.5 concentration outdoor to catch the real case of filter lifetime. And conduct the test to verify the results.
