Abstract:
Objective To verify whether the X brand air purifier could adsorb the formaldehyde in indoor air. Method An purifying test was carried out in a purified laboratory that had a volume of 30 m3, with an air leakage rate less than 0.05 m3/h, and was equipped with medium and high effective filters, air circulating ventilation system, gas sample generating system,etc. Results Significanly negative correlation was observed between the values of natural logarithm of formaldehyde concentration (lnCt) and time variables with a correlation coefficient r values of-0.995 0 ～-0.999 7. After the running of the air purifiers, the concentrations of formaldehyde in air significantly decreased with the prolongation of the running duration of air purifiers compared with its original concentration (P0.05). Conclusion This kind of air purifier could effectively adsorb formaldehyde in indoor air.
