biodegradable filter caps make clean drinking water accessible

 

In Colombia, about 3.7 million people lack access to clean and safe drinking water, a situation worsened by a devastating drought in 2024. Many of these people live in remote areas, where they endure extreme heat, and the limited water available is often contaminated. Ogilvy Colombia joins Filsa Water, the Colombian Red Cross, and Baylor International to provide an immediate solution for the world’s water crisis. Transforming the universal bottle cap into a powerful water filtration system, the 3D printed device allows safe water to be purified as it flows through, increasing the pH, adding hydrogen, reducing impurities by 70%, and eliminating 90% of heavy metals.

The Filter Cap is envisioned as a vital tool in humanitarian efforts and disaster relief. It offers an accessible way to purify water, serving as a portable treatment plant especially effective in areas where clean water is scarce or unavailable. By simply attaching the device to a standard PET bottle, users can have access to safe drinking water, thus reducing the risk of waterborne diseases and improving overall health and well-being.

 

Compact and lightweight, each Filter Cap weighs just 24 grams, serving as a portable treatment plant that can be easily distributed to even the most remote and underserved populations. For its production, 3D additive technology was utilized, composed of a mix of minerals, metals, and natural extracts, making it accessible, affordable, cost-effective. Designed to be environmentally responsible, the water filtration system also promotes the reuse of plastic bottles, while its casing is also 3D printed from cornstarch-based resin and can be composted after use.
