Standard 4 Stage RO (no DI) Replacement Filter Kit

This kit includes:

• Purtrex 5 Micron Sediment Filter
• MATRIKX CTO 5 Micron Carbon Block
• MATRIKX CTO 1 Micron Carbon Block

We recommend changing sediment filters when they become visually dirty or there is a noticeable drop in pressure. Change carbon blocks every 6-12 months depending on use. This kit does not include a membrane filter as they need replacement every three years or so, depending on water and set up.
