在室内外自然空气环境条件下，我们取６级安德森采样器的第２级和第６级组装成２级采样器．并和标准的６级采佯器进行捕获效果的比较、结果表明，两种采样器对空气细菌（５８９～５０００ｃｆｕ／ｍ３）和真菌（２２４～９８９ｃｆｕ／ｍ３）颗粒的捕获效果无明显差别（Ｐ＞０．０５）且呈显著的相关。
Under the natural and indoor air environment conditions, we take Level 6 and Level 6 Andersen samplers to assemble Level 2 samplers. The results showed that there was no significant difference between the two samplers in capturing airborne bacteria (589 ~ 5000cfu / m3) and fungi (224 ~ 989cfu / m3) particles (P > 0.05) and significant correlation.
