Our Foam Filters designed for laryngectomees measure 2 by 2 1/2 inches. They are available in two thicknesses, 1/8 or 3/16 inch. The filters are natural colored (no dye additives) and come in packages of 30, 60 or 90 filters. They have a single adhesive strip at the top for secure placement over the stoma.
Our soft patented plastic foam is designed for filtering air. The density, porosity, and thickness has been carefully calculated for best results when used by laryngectomy patients.
Our filters are chemical and dye free and made in the USA.
