Sanipure Water Systems is one of the leading manufacturer, supplier and exporter of superior quality Industrial Filter Cartridges in different types, various sizes, and grade qualities as we offer our products according to the client's requirements and specifications. If you live in an area with particularly 'hard' water or with a lot of contaminants, your filter may not last quite as long. It is possible that you may notice you need to change your filter as the water starts to smell or taste different. You may even begin to notice a chlorine taste or smell. However, sometimes you may not notice any change at all.
