Nasal filter for checking allergiesTNN, Mar 10, 2014, 09.18PM IST MUMBAI: Allergies, which affect 500 million people across the globe, could be controlled with a filter as small as an eye contact lens. Developed by Danish university scientists, the filter can control symptoms relating to allergic rhinitis or hay fever such as itching, sneezing or sniffling. The study has just been published online in the Journal of Allergy and Clinical Immunology. The researchers from Aarhus University said that the filter, which can be inserted in both nostrils, blocks specific particles in the air - including pollen from grass. Incidentally, grass allergy is one of the most common reasons for allergic rhinitis. The filter is not yet available in the market, with field tests set to begin later this year. Preliminary tests in our allergy chamber show that the filter can both alleviate typical symptoms, and that you will not experience unacceptable discomfort when using it, says Professor Torben Sigsgaard from Aarhus University. There was apprehension that people using the filter may end up breathing through their mouths, thereby worsening the effects of allergies. However, Initial studies have also showed that throat irritation - which is a common symptom of allergic rhinitis - was reduced by 75% using the nasal filter.
