The biggest difference is the Zero Pure Plus includes a built-in booster pump.
The Zero Pure Plus comes with a Booster Pump Kit (WP560043) designed to improve weak water pressure, speed up purification, and increase water flow, making it ideal for homes with water pressure below 40 psi.
Other key differences:
Water waste: The Zero Pure Plus features a ZeroWaste pump technology that redirects unused water back into your home's hot water supply rather than sending it down the drain, making it a more water-efficient choice.
Power requirement: The Zero Pure Plus requires a 110V electrical outlet to power its pump. The RO Pure Plus needs no electricity.
