Know before you buy
Yes, the system includes a dedicated smart faucet that allows you to dispense both purified hot and cold water directly from the unit.
The K6 is designed for a compact under-sink footprint, but you should ensure enough clearance for the main unit and the filter cartridges. We recommend checking the specific dimensions in the manual to ensure it fits comfortably alongside your existing plumbing.
A 600 GPD (gallons per day) flow rate means the system filters water quickly, allowing for a fast, steady stream when filling glasses or pots. You won't experience the slow trickle common with older, lower-capacity reverse osmosis systems.
This package includes the initial filter set plus an additional supply intended to last for two years of standard household use. This ensures you have replacements on hand immediately, saving you from needing to purchase new filters for the first 24 months.
Yes, the K6 system allows you to control the temperature settings for the hot water, giving you the flexibility to choose the right heat level for tea, coffee, or instant meals.
