Best match for Bellevue
Whole-house carbon for chlorine
No district prohibition on a brine drain turned up in the current file.
That is chlorine. A whole-house carbon filter with an NSF/ANSI 42 chlorine claim is the usual match. A softener will not take chlorine out.

Other options that still fit
Do not buy a softener on this supply
This supply is soft on the published numbers. A salt tank is usually the wrong box unless you are on a well or a different utility. Test the tap before you buy hardness equipment.
Under-sink reverse osmosis
The under-sink RO we actually run is Cloud RO — NSF/ANSI 58, kitchen tap, not a whole-house tank. Check the exact listing if PFAS is why you are shopping. Shop Amazon first for under-sink RO, or buy Cloud direct. Waterdrop is a tankless option if you want that path. A certifier-listed pitcher is the cheap first step. Nobody is paying for a medical claim.

Extra context besides the utility report and the chart above — geology, an unregulated table, or a published study. Not a second set of printed tap numbers.
- MicroplasticsWHO’s 2019 review examined studies that found microplastic particles in treated tap and bottled water in many places. That is a published-occurrence finding, not a number from this city’s water-quality report, and we do not invent a particles-per-liter count for the tap.Microplastics in drinking-water — World Health Organization
- FluorideSame 2025 report. Narrative says SPU adds fluoride; 2024 average 0.62 ppm. Table rows print Cedar 0.65 ppm (0.6–0.7) and Tolt 0.7 ppm (0.6–0.8).Average 0.62 ppm in 2024. Cedar 0.65 ppm (0.6–0.7). Tolt 0.7 ppm (0.6–0.8).2025 Water Quality Report — City of Bellevue Utilities
