product fit in the post-filter sump on my RO system. Does a great job. Water tastes grate. Tip - make sure you rinse the loose fines through the filter before drinking the water.

The main ingredient in almost all water filters is activated carbon, which is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for absorption of chemicals and impurities.
