Three disposable nose filters

A nose filter or nasal filter is an air filter designed to fit inside the human nostrils to prevent the nasal inhalation of allergens,[1] pollutants, and irritants such as dust, smoke, and foul odors. They are generally not intended for protection against toxic or injurious materials such as asbestos.[2]

The filters are available in various sizes, and typically have a center clip to facilitate insertion and removal. They are made in a variety of colors. Some designs incorporate an adhesive tab.[citation needed]
