The Avon CTCF50 Filter is a low profile combination filter containing a pleated high-efficiency filter element for removal of aerosols, particulate matter, smoke, fumes and a carbon bed for the removal of vapors that may be released from trapped particles. It is specifically designed for removal of riot control agents and tear gases including CS, CN and OC pepper spray. Available in packs of one (1) or four (4).

Humidity Indicator

A unique standard humidity indicator is located on the top of the CTCF50 filter and visually displays performance degradation due to moisture uptake over time. The indicator turns white to blue signaling that the unit pack was compromised and the filter must be discarded.


Compatible with Avon Protection C50™ Air Purifying Respirator only.
