    Abstract: The present invention provides compact nasal, oral and ear inserts with incorporated filters, specially designed to provide a more pleasant and healthy intake of air. Largely fabricated of a soft, pliable fabric such as compressed cotton, each Philter insert is comprised of two cylindrical filters, joined together via a flexible wire bridge. One example of the filtering material is activated charcoal, long known by the medical industry to be a safe, effective filtering agent for extracting liquids and gases from their harmful elements. As an additional consideration, this product is offered in several sizes to accommodate both child (under age twelve would require adult supervision) and adult users. The Philter inserts can be sold individually, or packaged with a dozen of more units per box.
