Thirty single-family homes with either high (> or = 2000 ng/g) or low (< or = 1000 ng/g) house-dust mite (HDM) allergen levels in mattress dust were examined for ventilation, thermal climate, and air quality (formaldehyde and total volatile organic compounds (TVOC). Elevated concentrations of HDM allergen in mattress and floor dust were associated with the difference in absolute humidity between indoor and outdoor air, as well as with low air-change rates of the home, particularly the bedroom. No correlation was found between concentration of TVOC or formaldehyde in bedroom air and HDM allergen concentration. In regions with a cold winter climate, the air-change rate of the home and the infiltration of outdoor air into the bedroom appear to be important for the infestation of HDM.
对30套独栋住宅进行了检查，这些住宅床垫灰尘中的屋尘螨（HDM）过敏原水平要么高（≥2000纳克/克）要么低（≤1000纳克/克），检测内容包括通风、热气候和空气质量（甲醛和总挥发性有机化合物（TVOC））。床垫和地板灰尘中HDM过敏原浓度升高与室内外空气绝对湿度差异以及房屋尤其是卧室的低换气率有关。未发现卧室空气中TVOC或甲醛浓度与HDM过敏原浓度之间存在相关性。在冬季气候寒冷的地区，房屋的换气率以及室外空气进入卧室的渗透率似乎对HDM滋生很重要。
