Indoor air pollution is one of the most common environmental health risks that doctors face. Although there are various tools for removing air pollutants such as household dust, there is insufficient information about the benefits of these tools. Particularly in modern homes, a central vacuum system is recommended.

To answer the question, “Have the central vacuum systems solved problems mentioned in Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) (Seasonal allergic) or not?”, 25 patients with a proven history of type 1 dust hypersensitivity disease were selected and for 3 months each of them used either the central or regular vacuum systems. In terms of clinical signs, in all 7 case studies evaluated based on physical activity, sleep patterns, unrelated symptoms, nasal functional problems, nasal symptoms, eye symptoms and general feelings, using a central vacuum offered superior results.

Thus this study revealed that the central vacuum cleaner, without being a drug, is a good solution for problems related to the allergies. Clinical research at the University of California (http://builtinvacuum.com/downloads/Clinical-Study-Central-Vacuum.pdf) has shown that using a central vacuum cleaner has brought substantive relief of allergic symptoms.

Percentage reduction of symptoms in allergic patients after using a central vacuum cleaner system at home and work is as follows:

Up to 47% reduction in nasal allergy symptoms (runny nose and congestion, itching, burning)

61% reduction in eye allergy symptoms (tears, itching, redness)

44% reduction in sleep-related symptoms (improvement in rest and sleep conditions)

48% reduction in nasal independent symptoms (skin allergy, sneezing, coughing)
