Many households in Nigeria lack access to safe drinking water. Sixty-three percent (63%) of the nation's population live in rural areas where only 3% of households have access to safely managed drinking water. This suggests an urgent need for intervention to offer sustainable solutions to drinking water needs at household levels. An operational research was commissioned by the United Nations Children's Fund (UNICEF) Nigeria to generate evidence to inform and guide Water, Sanitation and Hygiene (WASH) programming on household water quality. This involved an assessment of local manufacturing of household water filters; factors influencing social acceptability and market opportunities for clay and biosand water filters in Nigeria. Implementation of the research recommendations by the filter factories resulted in improved bacterial removal efficiency (>97%) in filters. Factors such as filter design and efficiency were shown to influence acceptability of filters, which influenced the price at which users were willing to pay for the filters in the study areas. The market research indicated low popularity of the filters due to lack of promotion and marketing of the water filters. The research outcomes show great potential for sustainability and marketability of clay and biosand water filters for household water treatment in Nigeria.

尼日利亚的许多家庭无法获得安全的饮用水。全国人口的百分之六十三（63％）居住在农村地区，那里只有3％的家庭可以使用经过安全管理的饮用水。这表明迫切需要进行干预，以为家庭一级的饮用水需求提供可持续的解决方案。联合国儿童基金会（儿童基金会）尼日利亚委托开展一项业务研究，以收集证据，指导和指导有关家庭水质的水，环境卫生和卫生（WASH）计划。这涉及对本地家用滤水器制造的评估；影响尼日利亚粘土和生物砂滤水器的社会接受度和市场机会的因素。过滤器工厂实施研究建议可提高过滤器中的细菌去除效率（> 97％）。研究表明，诸如过滤器设计和效率之类的因素会影响过滤器的可接受性，从而影响用户愿意为研究区域内的过滤器支付的价格。市场研究表明，由于缺乏水过滤器的促销和营销，该过滤器的普及率较低。研究结果表明，尼日利亚的家庭水处理用粘土和生物砂滤水器具有可持续性和可销售性。市场研究表明，由于缺乏水过滤器的促销和营销，该过滤器的普及率较低。研究结果表明，尼日利亚的家庭水处理用粘土和生物砂滤水器具有可持续性和可销售性。市场研究表明，由于缺乏水过滤器的促销和营销，该过滤器的普及率较低。研究结果表明，尼日利亚的家庭水处理用粘土和生物砂滤水器具有可持续性和可销售性。
