肉眼是無法看到細菌和塵蟎，而且一般的清洗對細菌和塵蟎來說起不到多大作用。要完全消滅或減少它們，還是需要用針對性的產品。請謹記，塵蟎是鼻敏感、哮喘、濕疹等敏感性病的致敏原。要多加留意家中小孩或長者有沒有敏感。
Bacteria and dust mites are invisible to the naked eye, and normal cleaning is ineffective for bacteria and dust mites. It is still necessary to use targeted products to eliminate these pests completely. Dust mites are also causes of allergic diseases such as nasal sensitivity, asthma, and eczema.
