equinox water filter Eq-15. Condition is "New". These filters effectively reduce contaminants such as chlorine, lead and many other common water pollutants. The EQ-10 filters, improve the taste and clarity of municipally treated water (again, not for well water). Here's how the triple stage filter works; In the first stage, a blend of inorganic minerals reduces chlorine, During the second stage, a highly advanced ceramic-coated absorbent media attracts and permanently bonds dissolved lead within a matrix pore structure. Finally , in the third stage of the water filtration process many primary health-related, organic contaminants are reduced. This is all housed in an ABS food-grade plastic capsule, assembled by ultrasonic welding to eliminate the use of glues and solvents. These highly effective, state-of-the-art, water filtration systems have achieved a rated capacity of 5,000 gallons (means 3-5 years of use for a typical household).
