  • STAGE 5 - 1x Inline Carbon GAC Filter (CL10ROT33-BB) - Replace every 6-12 months or as needed

Which Kit Do I Need?

We offer two kits to make annual filter changes easier:

Choose this kit WITHOUT the membrane when your current RO membrane is still in service.

  • Year 1 Kit (Includes RO Membrane):
    Ideal for your first full replacement, this kit includes all filters plus the RO membrane, which typically lasts up to 24 months.

  • Year 2 Kit found on this page (Without RO Membrane):
    After the first year, you only need to replace the pre- and post-filters, since the RO membrane is still good for another year. This kit helps you save money while keeping your system performing like new.

*Actual filter life may vary based on source-water conditions and volume of water treated.

Q&A

Q:

What is included in the Proline Plus kit YS-PROPLUS?

A:

It includes one RW-SED2510050 sediment prefilter, two OMB934-5m carbon block prefilters, and one CL10ROT33-BB inline GAC post-filter.

Q:

Which RO system does this replacement kit fit?

A:

The catalog lists EZ SYS-550EZ, Proline Plus. Check the exact model or part number on the existing equipment before ordering Proline Plus kit YS-PROPLUS.

Q:

Does this kit include the RO membrane?

A:

No. This is the annual filter kit without the Pentair 555694-00 50 GPD membrane, making it appropriate when the existing membrane is still performing within specification.

Q:

How often should the filters in this kit be replaced?

A:

Prefilters and post-filters are typically replaced every 6 to 12 months. RO membranes commonly last about 24 months, although incoming water quality and usage can shorten either interval.

Q:

What should I check before ordering this RO filter kit?

A:

Match the system model, individual filter part numbers, membrane capacity, and connection style. Do not rely only on the number of filtration stages because systems with the same stage count can use different components.

Q:

What should I do after replacing the filters?

A:

Inspect and lubricate reusable O-rings with a light coating of food-grade silicone, reassemble the housings or twist-in cartridges, restore water slowly, check for leaks, and flush according to the system instructions.
