Model CTD-C. This dual-cartridge countertop unit has a Doulton Silver Sterasyl ceramic pre-filter to effectively remove harmful bacteria, such as E. Coli, Fecal coliform, Salmonella, Streptococcus, and cysts (Cryptosporidium, Giardia), and sediment down to 0.9 micron (absolute). The cartridge can be cleaned up to 40 times (about once a month). 3 to 5 year life. Click for Performance Data. The second cartridge is the KDF/GAC filter. This KDF/GAC (Granulated Activated Carbon) and ceramic pre-filter unit sits on the counter and easily connects to any kitchen faucet. A diverter valve replaces the aerator on your faucet. In the regular position, water is sent through the aerator. For filtered water, turn on the cold water and rotate the plastic diverter valve knob (now a new more durable, long lasting, valve) - water is sent through the filter and out its own spout; a long reach spout allowing for placement flexibility on your countertop. It removes chlorine, heavy metals, pesticides and more (see What's KDF). Uses a replaceable cartridge (part no. KG--included), rated to treat 12,000 gallons. KDF/GAC also removes lead that may be present in old pipes. Flow rate is 1 gallon per minute. Can be converted for under-counter use with our Faucet Kit ($59.95). This filter may also be used to remove iron and hydrogen sulfide from well water. Includes chlorine test strips to verify when it's time to replace cartridge. 12" high, 5" diameter. 3 year prorated warranty on cartridge, 5 year on housings. The KDF/GAC water filtration system is the best system for performance and price.
