Abstract:
Objective To assess the removal efficiency of bacteria by water purifiers using different purifying materials. Methods The bacterial removal effectiveness of 7 types of commercially available water purifiers was tested using the National Standard Methods. Results Apart from one type using a single activated-carbon filtering material, the bacteria removal effectiveness of the other 6 types of water purifiers met the requirements of water purification device according to the rated treated-water-capacity conditions. Conclusion The removal efficiency of bacteria by water purifiers made from different filtering materials was different. Bacteria elimination effectiveness of a single-filtering material was lower and it is inversely proportional to its water-treating capacity. Water purifiers using multiple-purifying materials gave better removal efficiency of bacteria.
