The Avon NH15(TM) CBRN Air Purifying Escape Respirator is the smallest and most compact escape hood on the market, approved to carry NIOSH and CE marking. Its low cost makes it ideal for police, emergency medical services and fire officers seeking immediate or emergency respiratory protection in a CBRN scenario. The NH15 Combo is a revolutionary new carbon monoxide (CO) resistant, super compact CBRN escape hood, based on Avon's widely acclaimed NIOSH approved NH15. The NH15 Combo offers unsurpassed levels of respiratory protection for escape from hazardous environments, particularly when dangerously high levels of CO are present or likely in combination with other toxic materials and gases such as found in a smoke filled environment. The NH15 Combo is quick and easy to put on as it includes a non adjustable harness to increase the ease of fitting. The hood is made of transparent material to maximize the field of view and reduce any feeling of claustrophobia. The twin filters remain close to the face and minimize breathing resistance while maximizing gas, vapor and particulate protection.
