Summary

This study aimed to assess the impact of air cleanser on allergic rhinitis patients and indoor air quality. Air cleaners will be installed in the bedrooms and living rooms of the mite allergic rhinitis patients who aged 18-60 years.

Main parameters:

\- Symptom medication score of allergic rhinitis

Supportive parameters:

* Visual analog scale of allergic rhinitis
* Quality of life score of allergic rhinitis
* Indoor air quality measurement
* Indoor allergen level measurement

Conditions

  • Allergic Rhinitis

Interventions

DEVICE

PuriCare (HEPA Air Cleaner)

The active comparator group is a group that uses machines that have the same functions as those on the market. In intervention group, two air-cleaners will be activated, one in the living room (covers 91 m2) and the other in the bedroom (covers 58 m2). The air cleaner will be operated continuously for 6 weeks. Inside the air cleaner, a device for measuring the quality of the indoor air is built in. It will be used to compare indoor air quality before and after air cleaner operation. In order to maintain the double-blind setting, a label for 'prohibition of opening' will be attached to the joint of the outer case, and a sticker to cover the air quality measurement display part built in the air cleaner itself will be attached.

DEVICE

Mock device of PuriCare

The Control group operates the air-cleaner with the same appearance as the experiment group. However, all the filters including HEPA filter will not be inserted in this group (mockup devices). Two mockup air-cleaners will be activated, one in the living room (covers 91 m2) and the other in the bedroom (covers 58 m2). The mockup devices will be operated continuously for 6 weeks. Same as active comparator group, a device for measuring the quality of the indoor air is built in the mockup air cleaner. It will be used to compare indoor air quality before and after air cleaner operation. In order to maintain the double-blind setting, a label for 'prohibition of opening' will be attached to the joint of the outer case, and a sticker to cover the air quality measurement display part built in the air cleaner itself will be attached.
