A newly developed type of filter can help people with nasal symptoms from seasonal hay fever, clinical research suggests. The filter, which is not yet in production, works by being inserted in both nostrils. Depending on the filter's density, it blocks specific particles in the air -- including pollen from grass, which is one of the most frequent causes of hay fever (seasonal allergic rhinitis).
