Questions about this system
How is Tankless RO different from the RO System?
The RO System keeps purified water in a storage tank. Tankless RO makes it as you need it, so it takes less room under the sink. Both use a reverse osmosis membrane and a dedicated faucet.
How do I know when a filter needs changing?
Filter life is shown on the unit and tracked on your phone.
Can it make alkaline water?
The dedicated faucet comes with alkaline options. Ask about them when you book your free water test.
