Combating Fluorosis – Andhra Pradesh

Excess fluoride in drinking water sources in Anantapur district of Andhra Pradesh has made the area’s marginalised, rural population vulnerable to fluorosis.

UNICEF has introduced domestic de-fluoridation filter units, which can be used in homes to remove excess fluoride from drinking water.

Developed in collaboration with the Indian Institute of Technology, Kanpur, this easy-to-use device, where water poured into the upper chamber is collected and filtered into the lower one, reduces the fluoride content to acceptable levels.
