Laboratory tests indicate that the Xcaper filter will trap anhydrite water-soluble gases such as Hydrogen Cyanide, Carbon Monoxide and Acrolein! The filter will last 8-12 hours in a wildland situation. For optimal performance, keep the Xcaper filter in its original vacuum sealed, airtight bag until ready to use. The Easy Breathe Filter is easier to breathe though in those situations where drawing breath is more difficult. *Also available in a discounted six pack.
NOTE: THIS IS A ONE-TIME USE PRODUCT
