Nasal filter shows promise for alleviating allergies

  • 0

A new nasal filter, about the size of a contact lens, has been shown to greatly reduce allergy symptoms in a preliminary study in Denmark.

Researchers from Aarhus University in Denmark tested a new filter, which is inserted into both nostrils, against a filter-less placebo. They found patients with the filter experienced less sneezing, itching, and running nose, all symptoms associated with pollen-related allergies. Researchers were also curious how the nasal filter would affect breathing, but found patients with the filter experienced 75 percent less irritation in the throat than those with the placebo. The filter, called Rhinix, will be tested on a larger scale later this year.
