The RF-5050 replacement Filter 5-Pack also provides two solid block activated carbon filter cartridges. Over time the absorptive capacity of the activated carbon cartridges decline. The microscopic pores of the activated carbon block become saturated with contaminants. When this happens, the activated carbon can no longer efficiently remove chemicals from your drinking water. Tastes, odors and chemical contaminants will begin to pass through the filter system. The APEX solid block carbon cartridges contain super-absorptive coconut shell activated carbon for exceptional removal of organic contaminates like MTBE from gasoline spills, solvents, pesticides, chlorine, chloramine and naturally-occurring musty tastes and odors. APEX high-grade activated carbon cartridges remove more contaminants than other carbon cartridges. Unlike low-grade replacement carbon cartridges, APEX carbon cartridges wont release black carbon fines which can clog the RO membrane. We recommend replacing the cartridges no less than once a year to guarantee safe, pure drinking water.
The RF-5050 Replacement Filter 5-Pack contains an exact-fit 50 gallon-per-day reverse osmosis membrane. RO membranes remove total dissolved solids (TDS), sodium, water hardness minerals and heavy metals like aluminum and lead. Reverse osmosis membranes operate under high pressure, squeezing the contaminants out of your tap water. Mineral deposits and traces of chlorine eventually degrade the RO membrane. This reduces the efficiency and effectiveness of the filtration system. Periodic replacement of the APEX TFC membrane ensures clean, safe water day after day. This is especially important to prolong the life of coffee makers, commercial food steam trays, dental equipment, laboratory autoclaves and other equipment that is damaged by mineral scale build-up. We recommend replacing the reverse osmosis membrane every two years to maintain consistently fresh, purified water at all times.
The RF-5050 Replacement Filter 5-Pack also includes one granular activated carbon polishing filter. This powerful filter catches any trace of taste and odor-causing chemicals and gasses so every gallon of water looks and tastes great. The easy to use slip-fittings make it simple to replace this important filter component. Replace the polishing filter every one to two years.
