干蒸汽清洁最近作为一种降低屋尘螨 (HDM) 过敏原浓度和地毯含量的有效方法而受到关注，这项研究对其降低多环芳烃 (PAH) 和 HDM 过敏原水平的功效进行了评估。 2003 年和 2004 年，我们对 50 个铺设满墙地毯的城市家庭进行了研究，这些家庭大多是低收入且存在已知的铅污染。对两种地毯清洁干预措施进行了比较：单独重复 HEPA（高效颗粒空气过滤）吸尘和重复 HEPA 吸尘辅以干蒸汽清洁。收集真空样品以测量清洁前后地毯上的灰尘和污染物含量。通过配对比较来评估清洁方案在降低地毯中 PAH 和 HDM 过敏原水平方面的有效性。结果表明，两种清洁方法都显着减少了地毯中 PAH 和 HDM 过敏原以及灰尘的含量 (p < 0.0001)。通过干蒸汽清洁加上重复 HEPA 吸尘，灰尘 (64.4%)、PAH (69.1%) 和 HDM 过敏原 (85.5%) 的减少量比单独常规 HEPA 吸尘的减少量要大：灰尘 (55.5%)、PAH (58.6%) 和 HDM 过敏原 (80.8%)，尽管差异仅对于灰尘和 PAH 具有统计显着性。我们得出的结论是，密集的 HEPA 真空清洁大大减少了这些城市家庭地毯中 PAH 和 HDM 过敏原的含量，而干蒸汽清洁则适度提高了清洁效果。
Dry steam cleaning, which has gained recent attention as an effective method to reduce house dust mite (HDM) allergen concentration and loading in carpets, was evaluated in this study for its efficacy in lowering levels of polycyclic aromatic hydrocarbons (PAHs) as well as HDM allergens. Fifty urban homes with wail-to-wall carpets, mostly low-income and with known lead contamination, were studied in 2003 and 2004. Two carpet-cleaning interventions were compared: Repeated HEPA (High Efficiency Particulate Air filtered) vacuuming alone and repeated HEPA vacuuming supplemented with dry steam cleaning. Vacuum samples were collected to measure carpet loading of dust and contaminants immediately before and after cleaning. Paired comparisons were conducted to evaluate the effectiveness of the cleaning protocols in reducing the levels of PAHs and HDM allergens in carpets. The results indicated that both cleaning methods substantially reduced the loading of PAHs and HDM allergens as well as dust in carpets (p < 0.0001). The reductions in loading of dust (64.4%), PAHs (69.1%), and HDM allergens (85.5%), by dry steam cleaning plus repetitive HEPA vacuuming were larger than the reductions by regular HEPA vacuuming alone: dust (55.5%), PAHs (58.6%), and HDM allergens (80.8%), although the difference was statistically significant only for dust and PAHs. We conclude that intensive HEPA vacuum cleaning substantially reduced the loading of PAHs and HDM allergens in carpets in these urban homes and that dry steam cleaning added modestly to cleaning effectiveness.
