NOTE: It should be clearly understood that during tests performances the concentration of bacteria fed to the filtration element is artificially high in order to simulate a challenging test for the ceramic element. The most aggressive "real life" condition would normally be at least 1000 times less severe.

Those portable gravity fed water filtration systems are intended for use in situations where a reliable supply of safe drinking water is unavailable. Ideal for emergency situations such as hurricanes, floods, earthquakes etc. travelers, campers, field expeditions, rural clinics as well every day home use.
