The Delta Clarifi Tankless Under Sink 6-Stage Reverse Osmosis Starter Kit delivers certified, high-performance water filtration for your home. The starter kit includes the Clarifi RO system unit, a Delta beverage faucet in Arctic Stainless finish, and a Clarifi Remineralizer Cartridge that adds beneficial minerals — including electrolytes, calcium, and magnesium — back into purified water for better taste and enhanced pH.
The system uses six filtration stages across three cartridges (pre-filter, reverse osmosis filter, and carbon filter) and is proven to reduce more than 90 contaminants, including chlorine (96%), lead (99.3%), copper (99.97%), fluoride (91.1%), microplastics, PFAS, arsenic, heavy metals, nitrates, and pharmaceuticals. It is certified by IAPMO R&T to NSF standards 42, 53, 58, 401, and 372, as well as ASSE 1086 — making it the most certified tankless RO system in its class. The tankless design saves over 60% of under-sink space compared to traditional tank-based systems, measuring just 6-1/4 inches wide and 15-13/16 inches tall. Continuous tankless flow produces up to 600 gallons per day with a 2:1 filtered-to-waste ratio, which is 87.5% more efficient than the average tanked system.
Carbon and RO filters have a two-year lifespan, with filter change indicator lights and audible alerts to signal when replacement is needed. The system features a self-flushing function that automatically cycles water to prevent stagnation. It is WaterSense labeled and backed by Delta Faucet's warranty and live customer support. California Prop 65 Warning: Cancer risk from exposure to Nickel (Metallic). Wash hands after installing or removing the product.
