Straining and Filtration

Straining fine particles and microorganisms is a very simple method of filtration. In this process, water is pushed through a thinks cloth filter, which removes some of the suspended silt and solids and destroys some pathogens. After straining, water may not be perfectly safe for drinking but it can be a drinking water improvement step for people with no other treatment options. 

We use Ozone to take care of any bacteria or microorganisms prior to the filtration. Redundancy to protect your health while leaving in the essential minerals.
