Abstract

空気清浄機の除菌性能評価法を策定するために必要な基礎データを得ることを目的とした予備実験を試みた。供試微生物散布用の試験室を作製し, その試験室の空気中に浮遊させる微生物として<I>wallemia sebi</I>および<I>Penicillium freguentans</I>の胞子を用意し, 胞子の散布にネブライザ法および超音波法を適用し, 散布胞子の採取にゼラチンフィルタ法を用いた。ネブライザ法と超音波法の何れの方法でも, 試験室内に胞子を散布することができた。市販の空気清浄機の除菌性能 (空中浮遊菌除去性能) の評価試験を試みたところ, フィルタによる空中浮遊生菌濃度の低減効果が認められたが, クラスタイオンによる低減効果は認められなかった。

The preliminary experiments were tried to obtain the basic data for determination of the air-cleaner evaluation method on removability of airborne microbes. An examination room for spray of living microorganisms was prepared, the spores of <I>Wallemia sebi</I> and <I>Penicillium frequentans</I> were prepared for the spray, a nebulizer method and an ultrasound method were adopted for spray of the spores, and gelatin filters were used for sampling of the scattered spores in the air of the examination room. Both nebulizer method and the ultrasound method were applicable for spray of spores. The preliminary evaluation tests on removability of airborne microbes were tried on a commercially available air cleaner. Although the decreasing effect of airborne microbes with the filter was detected, the decreasing effect was not detected with the emission of cluster ions at the air cleaner.
