Are the nose filters safe to use?

The filters are made with hypo-allergic materials and had been tested for their safety via several studies (you can find the results of those studies in our Blog articles). Additionally, as a business we never had a complaint for any allergic reaction to the filters but it is always wise to test the product to a non-sensitive part of the skin, for several short time periods before proceeding with extended use. Also, you should always be aware of any changes you might feel when using the filters (such as difficulty breathing, or any other potential symtom you may encounter).  If you experience any syptom, you should stop using the filters immeditately and report your issues to us for future reference.
