Filter Replacement Kit with RO Membrane for Topway Global TGI WIN-445 Reverse Osmosis System
INCLUDES:
- STAGE 1 - 1x Sediment Pre-Filter (RW-SED2510050) - Replace every 6-12 months or as needed
- STAGE 2 - 1x Carbon Block Pre-Filter (OMB934-5M) - Replace every 6-12 months or as needed

We offer two replacement filter kits so you can get exactly what you need — and avoid paying for filters you don’t.
-
Year 1 Kit found on this page (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 (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.
*Filters may need to be replaced more often than indicated, depending on water contaminant levels and volume of water being treated.

Q&A
Q:
What is included in the TGI WIN-445 compatible kit?
A:
RW-SED2510050 sediment prefilter, OMB934-5M carbon block, AXEON 200359 50 GPD membrane, and K2533-JJ inline GAC post-filter.
Q:
Which RO system does this kit fit?
A:
The catalog does not provide an approved model list for TGI WIN-445 compatible kit. Match the exact part number, dimensions, connections, electrical rating, and treatment role shown on the existing component before ordering.
Q:
Does this kit include the RO membrane?
A:
Yes. It includes the 50 GPD RO membrane; choose the membrane-sold-separately version if the existing membrane still passes performance checks.
Q:
How often should the filters be replaced?
A:
Prefilters and post-filters are commonly changed every 6 to 12 months. RO membranes commonly last about 24 months, although water quality and use can shorten either interval.
Q:
What should I verify before ordering?
A:
Match the system model, individual filter part numbers, membrane capacity, and connection style. Stage count alone does not establish compatibility.
Q:
What should I do after replacing the filters?
A:
Restore water slowly, inspect all housings and tubing for leaks, and flush according to the system instructions before using product water.
