What is difference between E coli and coliform?
The main difference between E coli and coliform is that the E.coli are a type of bacteria; that is, a fecal coliform whereas the coliform is a bacterium involved in the fermentation of lactose when incubated at 3537C. The other type of coliform bacteria is non-fecal coliforms that are Enterobacter and Klebsiella.

Will a water filter remove coliform?
Biological contaminants such as coliform bacteria are most effectively eliminated through chlorine disinfection, filtration, ultraviolet irradiation, and ozonation. … This can be accomplished with either a whole home filtration system, an under the sink solution, or a counter top system like the Berkey Water Filter.
