The experimental study of intranasal synthetic filter with stent was tried to decrease suspended particulate matter for human respiratory tract. Facial mask or surgical mask were evaluated. Nasal vestibular size in Thai adults was estimated. Different kinds of stents and filters were used. Standard anterior rhinomanometry was the proper objective method to test nasal air flow resistant of stent and filter. Nasal obstructive symptom correlated well with rhinomanometric results. One layer of outer and inner face mask at each end of the cylindrical silicone stent was the suitable device. There were no complications or side effects. This personal protective device was cheap and available. The filtration efficacy should be tested in a general population during a highly air-polluted period.
