Immediate Compact Protection

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 Avon NH15 Combo™ CBRN Air Purifying Escape Respirator is the smallest and most compact escape hood on the market approved to carry a NIOSH marking. The NH15 Combo™ hood has a five year shelf life and provides a high level of respiratory, eye and face protection for a minimum of fifteen minutes. Its low cost makes it ideal for police, emergency medical services and fire officers seeking immediate or emergency respiratory protection in a CBRN or CO scenario.

The clear material gives a non-threatening appearance, aids with recognition of the wearer and also allows for superior visual communication. Twin low-profile filters on a unique hinge system feature the latest filtration media which reduces breathing resistance and a front reflector makes it easier to identify colleagues in low light environments.
