Did you know that your bedding may be hosting millions of dust mites, also know as bed bugs? If you suffer from burning eyes, a runny nose and morning headaches you may have these tiny creatures and the allergen in their feces invading your bed. The allergen thrives in warm moist environments such as mattresses and pillows and causes allergic reactions when inhaled. Suffer no longer and use one of our polymer fitted pillow protective covers. Our Polymer Fabric pillow cover is "dust mite and fecal pellet proof," completely air permeable for hygiene, yet absolutely impenetrable by the nasty mites and their fecal allergen. Poly Cotton Allergy Protective Pillow Covers are sold in all sizes. We recommend the Poly Cotton Fabric (Polyurethane inner membrane) for people with severe allergies or older bedding that may already contain dust mites. Machine washable. Line dry or tumble dry on lowest setting. DO NOT bleach or iron.
