One of the United Nations Millennium Development Goals is to reduce to half by 215 the number of people, worldwide, who lack access to safe water. Due to the numerous deaths and illnesses caused by waterborne pathogens, various household water treatment devices and safe storage technologies have been developed to treat and manage water at the household level. The new approaches that are continually being examined need to be durable, lower in overall cost and more effective in the removal of the contaminants. In this study, an extensive literature survey was conducted to regroup various household treatment devices that are. Highlights: The CCF filter achieved the highest turbidity reduction (95%) among all the filters. The BF filter was found to be the most efficient at removing chemical contaminants. The highest bacteria removal efficiency was recorded by the SIPP (99 1%). SIPP filter is recommended as a household water treatment unit in rural communities.
