The Cooper polyethylene inhaler is designed for inhalation without risk of burns, and is easy to use, helping to relieve ENT (ear, nose, larynx) inflammation. The canister can hold about one liter of liquid, and the width of the cone allows inhalations without wasting liquid and without having to hold a cloth over the head. It adapts to the shape of the nose and comes in two mask sizes for adults and children. Color and design may vary depending on availability.
