systems are attached to the water line as the water enters the home and
treats all the water entering the home. Point-of-entry systems are
addressing a broad spectrum of water treatment and purification needs.
systems are large, high capacity, high flow rate head, and sump filters
are plumbed in so that all or most of the water entering passes through
Point-of-entry systems are usually expensive to buy and to install as
to point-of-use equipment and pitchers.
Point-of-use counter top (CT) systems: These
systems are portable and no permanent installation is required. These
