This granular activated carbon post-filter is designed for use as the final filtration stage in Microline CTA and TFC reverse osmosis systems, as well as the Rayne Clear 3-stage RO system. Positioned after the RO membrane, it provides a final polish to your water by reducing any residual chlorine, taste, and odor that may remain after filtration — ensuring the water at your tap is as clean and palatable as possible.
Because GAC post-filters work downstream of the membrane, where water is already at its cleanest, they are particularly effective at delivering that final improvement in taste and odor that makes a noticeable difference at the point of use. The push-in with O-ring connection makes replacement simple and tool-free, and the filter should be changed every 6 to 12 months to maintain peak performance.

Q:
What is the Microline S7025 used for?
A:
It is an inline granular activated carbon filter used to reduce chlorine taste and odor, often as a polishing stage on an RO system, water cooler, ice machine, drinking fountain, or under-sink line.
Q:
Which systems does the catalog associate with the Microline S7025?
A:
The catalog lists S7025, CTA-14D, CTA-14S, TFC-25D, TFC-25S, TFC-300, TFC-335, TFC-435, Rayne Clear, Impression 4. Check the exact model or part number on the existing equipment before ordering Microline S7025.
Q:
What connection option should I order?
A:
This cartridge uses a push-in O-ring connection. Match the S7025 part number and inspect the sealing O-rings before installation.
Q:
Does the Microline S7025 have a required flow direction?
A:
Yes. Install it in the direction marked on the filter body so water passes through the media as designed.
Q:
How often should this inline carbon filter be replaced?
A:
Replace it every 6 to 12 months or according to the equipment schedule. Water use, chlorine loading, and a return of taste or odor can shorten the interval.
Q:
Can I choose another inline filter just because it is 2-by-12-inch?
A:
No. Match the media type, body length and diameter, connection size, flow direction, and equipment requirements. Similar-looking inline filters can serve different treatment roles.
