Particles exist in almost all water sources. The particles range from rocks, sediment, dirt, dust, silt, or minor sizes of microorganism (cyst & giardia), Algaes, or bacteria, virus.. etc. and even all chemicals could be defined in sizes in molecule or atoms. Caware particle reduction technology effectively stop ranges of particles contaminants by physical reductions. To acquire for safe water without particles contaminated, Caware provides depth thermal bonding filter, pleated filter, hollow fiber, RO membrane..etc. in either nominal or absolute particulate micron ratings.
