Ultima Replacement RO Filter Pack

A full set of pre- and post-membrane replacement cartridges for your Ultima RO system’s annual service, sized to match your system’s stage count.

• 4-stage pack (RO3004) fits the Ultima VI and other 4-stage RO systems
• 5-stage pack (RO3005) fits the Ultima VII, Green 5-Stage, and other 5-stage RO systems
• Includes a filter wrench and instructions
• Does not include the RO membrane — order that separately if it’s due for replacement

Please note: this is the official OEM replacement for your Ultima system, sold under the same part number. Depending on what Ultima has in stock, the filter may ship with a different brand label.
