What RO adds to Cooper City water
- Chlorine taste and smell: the city's 2025 report lists a 1.9 ppm average residual. The carbon stages handle it at the drinking tap.
- Lower dissolved solids: the RO membrane is finer than the city's softening membranes, so it reduces what remains, including sodium (16 ppm in the report).
- Certified claims: for any specific contaminant, check the exact model's NSF/ANSI 58 listing.
Two membranes, two jobs
It is fair to ask why you would add a membrane to water that already went through one. The city's membrane softening is designed to remove hardness, color and organic matter at scale for the whole city. An under-sink RO membrane is tighter and treats only the small amount of water you drink and cook with, after it has travelled through the pipes. One is a city-wide treatment step; the other is a final polish at your sink.
Why alkaline
RO water is low in minerals. Living Water's alkaline RO adds a remineralization stage after the membrane, which many people prefer for taste. It is a taste choice, not a health claim. See alkaline vs. standard RO.
Installation in a Cooper City kitchen
- Unit and tank in the sink cabinet, or a tankless unit where space is tight.
- A dedicated faucet, using a spare hole or a new one in the counter.
- Connections to cold water and the drain.
- Optional line to the refrigerator or ice maker.
- Flushing and a walkthrough of filter changes.
RO or whole-home?
RO covers one tap. If chlorine smell in the shower bothers you as well, a whole-home system treats every tap. See the drinking water system guide for a side-by-side.
Fluoride and RO
Cooper City stopped adding fluoride in 2025 under the new state law, though natural fluoride can remain. Some households still choose RO partly because it is a common method for reducing fluoride at the drinking tap. If that matters to you, check the exact model's certification for fluoride reduction. See fluoride filters in Cooper City.
