Matched to what EPA's records actually show for LAFAYETTE UTILITIES WATER SYSTEM (grade A, 100/100) — not to what sells.
EPA SDWIS/ECHO 2026Q2 · UCMR5 (2023–2026, July 2026 release) · SYR4 six-year review 2012–2019 · Full Lafayette water quality report · Methodology
Carbon pitcher or faucet filter for taste (optional). LAFAYETTE UTILITIES WATER SYSTEM's EPA record is clean: no health-based violations in five years, lead at 0 ppb at the 90th percentile, and none of 290 UCMR5 PFAS results were at or above the reporting limit. Most Lafayette households need nothing more than a carbon filter for chlorine taste — and a lead-certified one if the house has old plumbing.
Not on the strength of EPA's data for LAFAYETTE UTILITIES WATER SYSTEM: no health-based violations in five years, lead at 0 ppb. A taste filter and a lead-certified cartridge for older homes are all most households need.
An NSF/ANSI 42 carbon pitcher or faucet filter for chlorine taste; add NSF/ANSI 53 lead reduction if your home predates 1986.
LAFAYETTE UTILITIES WATER SYSTEM's latest Lead and Copper Rule 90th-percentile result was 0 ppb (2023-01-01 to 2025-12-31), below the 15 ppb action level. Lead enters from service lines and home plumbing, so test at the tap if your home is older.
No. None of the 290 UCMR5 PFAS results for LAFAYETTE UTILITIES WATER SYSTEM (2024-11-19 to 2025-05-20) were at or above the reporting limit.

Utility data describes water leaving LAFAYETTE UTILITIES WATER SYSTEM. Lead, copper and some PFAS enter between the main and your faucet, so a mail-in lab test is the only way to know what your household actually drinks — and the cheapest way to avoid buying a filter you do not need.

A filter is only certified up to its rated capacity — breakthrough happens when a cartridge runs past it. Budget the cartridges, not just the unit.
| Filter | Change interval | Annual cartridge cost | Replacements |
|---|---|---|---|
| Reverse osmosis (APEC ROES-50) | typically pre-filters every 6–12 months, RO membrane every 2–3 years, post-carbon yearly | typically $50–$90 | Replacement RO filter sets → |
| Under-sink carbon block (Waterdrop TSA / 10UA) | typically every 6–12 months (rated 8,000 gal or 12 months) | typically $30–$60 | Replacement under-sink cartridges → |
| Pitcher (ZeroWater / Brita Elite) | typically every 2–6 months (ZeroWater 20–40 gal depending on TDS; Brita Elite 120 gal ≈ 6 months) | typically $60–$150 | Replacement pitcher filters → |
Amazon Subscribe & Save ships cartridges on the interval you choose at a small recurring discount, which is the easiest way to keep a certified filter within its rated life. Costs are typical retail figures, not quotes; check the capacity printed on your exact cartridge.
