MS Filter Systems was founded in 2001 to deliver practical and sustainable water treatment solutions for small communities. Rather than scaling down a complex treatment process that is difficult and expensive to maintain, MS Filter's approach has been to enhance a time tested process that is ideal for small systems. These enhancements greatly expand the range of raw water quality that the process can treat to a quality unequalled by far more complex systems. We have enhanced the time-tested process of slow sand filtration in a multi-stage filtration package that is ideally suited for remote communities of 2,000 residents or less, while maintaining the highest treated water quality standards. It is a chemical-free, natural, biological process based on slow sand filtration, enhanced with pre-ozonation and roughing filtration.

Our system is proven to achieve the biological removal or inactivation of taste and odour compounds, endocrine disrupting compounds, pharmaceuticals and algal toxins and pathogens such as Giardia and Cryptosporidium.  The addition of a robust ozone pre-treatment and a carbon-capped roughing filter allows us to treat raw water of lesser quality than conventional slow sand plants. The MS Filter System can be customized to flow capacities between 20 and 2000 cubic meters per day. The fundamentals of slow sand filtration are reliable, easy to operate, and require no added chemicals, no chemical delivery, and no consumables. With no moving parts in the filter, operator time is a fraction of that with other systems and limited to daily monitoring, occasional sampling, and filter cleaning every 2-6 months. With low energy consumption and no chemical wastewater produced, the MS Filter System has the smallest carbon footprint of any water treatment technology.

These inherent qualities have made our system the obvious solution to the drinking water shortfalls in small communities and remote locations. Our system has been instrumental in lifting several long-standing boil water advisories, and subsequently laying the bedrock for economic development and growth in these communities.
