The modern respirator using activated carbon was invented in 1854 by John Stenhouse and is still in use today.
 It is a 40mm long activated carbon filter consisting of two 6.8mm diameter tubes.
 Provides respiratory protection in times of crisis and is your companion in disaster preparedness.
 If you are escaping from a fire situation, you have about 10 vital breaths available.
 Provides higher protection performance than wet wipes.
 It can also be used as a water filter.
 In case of emergency, soak it in contaminated water and suck it out slowly for use.
 It can purify approximately 5L of 3rd grade water (rainwater that falls on soil).
 -caution-
 It has limited purification capacity due to the small tube capacity.
 All gas respirators in the world have a limited lifespan, so use replacement kits at set intervals.
 Not intended for long-term use in fire scenes.
