For this Sans Water Purifier review we put the system through a series of objective and subjective tests to find out how it matched up to its performance claims. Most importantly we conducted lab testing to see which contaminants it removed from our water, as well as ranking its purification speed, design quality, ease of setup and maintenance, and company policies.

In-depth Sans Water Purifier review covering our independent lab testing, setup, design, contaminant removal, maintenance, and overall value.
