Specifically designed to set the standard in the industry, the CPR MICROMASK features a positive, one-way, non-rebreathing valve complete with filter. This valve has a large opening to reduce restrictive rescue breathing. The ever popular fold-down styling makes for a low profile, easily accessible package that includes a pair of disposable gloves in a durable nylon belt pouch. The CPR MICROMASK is available as a single use mask or a reusable mask with a single use disposable one-way valve.
