This collection of materials includes trainer tools and resources to promote the behaviours to purchase, use, and maintain a ceramic candle filter. The intervention is called, "Take no chances!" This intervention was implemented by ENPHO, CAWST, and local partners; Upward Spiral developed the intervention design, and communication and learning materials; and Nepal Creative House produced the audio-video materials. It was implemented from 2019-2020 in five districts of Nepal: Dolakha, Sindhupalchok, Nuwakot, Kavre, and Dhading. The behaviour change intervention includes interpersonal communication through group and household activities. These materials are available thanks to funding provided by Global Affairs Canada as part of their Nepal Earthquake Relief Fund.
