The desktop water filter will introduce children to the principles of operation of treatment plants that supply drinking water. For additional water purification in factories and enterprises use more complex filtration systems, add chemicals to the water for disinfection, treat with ultraviolet light. Please note: the filter from the 4M research kit is not intended for drinking water.
