High-efficiency particulate-arrest-filter vacuum cleaners are recommended to allergy sufferers although their use increases personal cat allergen exposure. We aimed to measure personal mite allergen exposure during vacuum cleaning by nasal air sampling and to compare exposures while vacuuming and emptying the vacuum cleaner bag.
Five brand new high-efficiency vacuum cleaners were selected. An old, previously used vacuum cleaner with its original microfilter in situ was used as a control. Nasal air samples were taken prior to and during vacuum cleaning in 10 homes. Samples were processed by HALOgen assay. Personal mite and cat allergen exposure was measured as the dust compartments were emptied.
There was an increase in personal mite allergen exposure with vacuum cleaning, which approached significance (P = 0.058). There was no difference between the high-efficiency vacuum cleaners and the control vacuum cleaner (P = 0.141). When the dust compartments were emptied, personal mite and cat allergen exposure increased (P < 0.02). CONCLUSIONS. The increase in personal mite allergen exposure while vacuum cleaning in an area with mild to moderate mite allergen exposure is small. High-efficiency vacuum cleaners confer no benefit and cannot currently be recommended to allergy sufferers as a means of reducing personal mite allergen exposure.
尽管使用高效微粒空气过滤器真空吸尘器会增加个人接触猫过敏原的机会，但仍建议过敏患者使用。我们旨在通过鼻腔空气采样测量真空清洁过程中个人接触螨虫过敏原的情况，并比较吸尘和清空吸尘器集尘袋时的接触情况。
选择五台全新的高效真空吸尘器。一台旧的、之前使用过且原位安装有原装微滤器的真空吸尘器用作对照。在10户家庭中，在真空清洁之前和期间采集鼻腔空气样本。样本通过HALOgen检测法进行处理。在清空集尘袋时测量个人接触螨虫和猫过敏原的情况。
真空清洁后个人接触螨虫过敏原增加，接近显著水平（P = 0.058）。高效真空吸尘器与对照真空吸尘器之间没有差异（P = 0.141）。当清空集尘袋时，个人接触螨虫和猫过敏原增加（P < 0.02）。结论：在螨虫过敏原暴露程度为轻度至中度的区域进行真空清洁时，个人接触螨虫过敏原的增加幅度较小。高效真空吸尘器并无益处，目前不能作为减少个人接触螨虫过敏原的手段推荐给过敏患者。
