FILTRATELITE is a filter that uses small light membranes. It is portable and can be used in emergency situations, for natural disasters and in remote locations. It uses gravity elevation to filter murky water into clean water and so does not require any external energy source. The water produced is not entirely bacteria-free. It filters 6 litres of water per hour and is sufficient for a family of 5 people. It is low cost and can last up to 2 years if properly maintained.
