Study Finds Proper Maintenance Essential for Effective Household RO Water Systems

A recent study in Chennai found that while household reverse osmosis (RO) systems reduce microbial contamination in drinking water, they do not guarantee safety without proper maintenance and regular filter replacement. The study analyzed 262 water samples from 216 households, revealing that 31 post-RO samples still contained E. coli, compared to 71 in untreated water. Education levels influenced outcomes, with higher contamination in samples from less-educated respondents. The findings highlight the importance of maintenance and awareness for effective RO system use.
