# Colloidal Silver Ceramic Filters Martin Bolton's ‘Rural Water Filter' is Superb By Nika Kubiak | Published 2009-04-05 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/Portable-life-saver-designer-products References: [existingvisual](http://www.existingvisual.com/yankodesign/2009/03/31/aqua-hydra-or-simply-water-it-needs-to-be-clean/) & [martinboltondesigner](http://martinboltondesigner.com/ruralwaterfilter.htm) To improve the quality of water in developing countries like Africa, Martin Bolton came up with a low cost water treatment design that utilizes colloidal silver in a ceramic filter. Bolton’s ‘Rural Water Filter’ features a ceramic filter coated in colloidal silver. The colloidal silver has antibacterial, disinfecting qualities in ceramic that make it quite promising for a water treatment design. The Master’s project at the [University of Johannesburg](https://www.trendhunter.com/trends/zeidler-architecture) has not yet been published, but it is an important concept helping to resolve health issues in many developing countries and war-torn zones. ## Trend Insights (Trend Hunter) - Score: 1.5/10 - Popularity: 15% | Activity: 21% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Africa ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### What Makes This Trend Stand Out - **Low-cost Water Treatment Design:** Martin Bolton's 'Rural Water Filter' offers a low-cost water treatment solution for developing countries using colloidal silver ceramic filters. - **Colloidal Silver Technology:** The use of colloidal silver in ceramic filters presents disruptive innovation opportunities in the water treatment industry. - **Health Solutions for Developing Countries:** Martin Bolton's 'Rural Water Filter' provides a potential solution for health issues related to water contamination in developing countries. ### Sectors Adopting This - **Water Treatment:** The 'Rural Water Filter' design can disrupt the water treatment industry with its innovative use of colloidal silver ceramic filters. - **Ceramics:** The incorporation of colloidal silver in ceramic filters opens up opportunities for innovation in the ceramics industry. - **Healthcare:** The 'Rural Water Filter' design addresses health issues in developing countries, highlighting potential innovation in the healthcare industry. ## Related on Trend Hunter - [3D-Printed Water Filtration Caps](https://www.trendhunter.com/trends/filter-caps.md) - [Bulbous Clay-Made Water Filters](https://www.trendhunter.com/trends/biologique-water-filter.md) - [Water-Purifying Jerrycans](https://www.trendhunter.com/trends/water-purification-jerrycan.md) - [Sustainable At-Home Filters](https://www.trendhunter.com/trends/compostable-water-filters.md) - [Dual Filtration Tumblers](https://www.trendhunter.com/trends/water-filter-tumbler.md) - [Compatibly Compact Water Filters](https://www.trendhunter.com/trends/compact-water-filter.md) - [Water Purifier Devices](https://www.trendhunter.com/trends/ladislamp-disinfection.md) - [Titanium-Made Water Purifiers](https://www.trendhunter.com/trends/grayl-ultrapress-titanium-purifier.md) - [Vibrant Metal Water Purifiers](https://www.trendhunter.com/trends/conecto.md)
