What Is a BioSand Water Filter and How Does It Work?

A BioSand water filter is an enclosed filtration system that can reduce impurities by up to 98 percent. Simple use of mechanical and biological processes remove heavy metals, bacteria, viruses, protozoa and other impurities from the water. It is composed of four simple layers of easily sourced materials within a concrete structure: (1) Diffuser plate, (2) Fine sand, (3) Course sand, (4) Gravel.

Water from a questionable, dirty or contaminated source is poured into the top of the filter’s square opening. Gravity alone helps the water flow down through each of the four layers, which filter out nearly all of the water’s impurities. Water is then forced up through a pipe and out into the waiting container. Easy-to-understand maintenance can keep these filters working for up to 20 years.

The cost to construct a BioSand water filter through GFA World is only $30. In 2019 alone, GFA World distributed 12,243 filters to people in 16 Asian nations. In areas where there is perhaps an abundance of water but the water is contaminated, these filters are an incredibly sustainable way to help a family or small group take existing water and make it useable for drinking, cooking and washing.

Families and villages with these filters have seen waterborne illnesses dramatically reduced or eliminated and health fully restored to those previously plagued by ongoing issues related to diseases and conditions such as constant diarrhea, stomach pain, dizziness, headaches and poor appetite. Often a village will share its water source with its livestock, which leads to small ponds or lakes being filled with extremely harmful bacteria and diseases. This is exactly the scenario where an easily-used filter can mean the difference between health and chronic illness.

These portable, affordable filters are good for areas where drilling for a well just isn’t feasible, such as when a well cannot be drilled to the appropriate depth. BioSand water filters can be installed inside or nearby a home, and they require no electricity.

It’s easy to sponsor a BioSand water filter through GFA World. Just $30 today means water for a family for many years, clean and safe. You can know that your investment is in something that anyone can use and maintain for their family’s health. Turn the cost of one typical meal in a restaurant into the transformative power of drinkable water for a vulnerable family. In a world where billions of people don’t have access to clean water, your gift to GFA World is guaranteed to touch the life of someone in need.
