Model CTD-N. This dual-cartridge countertop filter uses a special cartridge that removes nitrate from the water. The second cartridge is our 12,000 gallon capacity KDF/GAC filter. 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. 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. Suggested Retail - $255, Sale Price - $169.95 plus free shipping (continental US only). ORDER NOW! VIEW CART/CHECKOUT.
