New York City's tap water is among the best in the country. In 2025, 91.3% came from the Catskill and Delaware systems, which are protected well enough upstate that they operate under an EPA filtration waiver; the other 8.7% came from the Croton system, which is filtered. But lead from service lines and building plumbing means a good water filter still makes sense, and a filter also covers the rare low-level PFAS detection. A reverse osmosis system handles both. A certified pitcher filter is a solid budget option for lead.
Is New York City tap water safe to drink? NYC tap water meets all federal and state drinking water standards, and DEP reports no lead in its distribution system. However, lead can enter the water between the main and your faucet through old service lines and plumbing. In December 2025, DEP counted about 121,100 known lead or galvanized service lines, with many more of unknown material, and in 2025 tap sampling 16 of 326 homes were above the 15 ppb action level (90th percentile: 10 ppb). Homes built before 1961 may have lead service lines, and lead solder was used in plumbing until 1986, so if you live in an older building, a certified lead filter adds an extra layer of protection.
Does New York City water have PFAS? Very little. NYC's EPA UCMR5 sampling found no PFAS at reporting limits. In DEP's own 2025 sampling, PFOA was detected once, at 2.7 parts per trillion in a single Bronx sample (below both New York's 10 ppt limit and EPA's 4 ppt limit), along with one low PFHxA detection; every other sample was non-detect. You can see the results for your zip code.
Do I need a water filter in NYC? It depends on your building. Most NYC housing is old (in the city's 2023 Housing and Vacancy Survey, 54% of units were built before 1947), and in an older building a lead-certified filter is a smart precaution since lead can leach from old service lines, pipes and solder. If PFAS is a concern, a reverse osmosis or carbon block filter certified for PFOA/PFOS reduction will lower your exposure. For taste alone, even a basic carbon filter will reduce chlorine flavor, since NYC disinfects with chlorine.
What's the best water filter for a NYC apartment? For most NYC apartments, a ZeroWater pitcher or Brita Elite pitcher is the easiest starting point: no installation, certified for lead, and fits in a small kitchen. If you can install under the sink, Clearly Filtered says its 3-Stage under-sink system reduces 232+ contaminants including PFAS, based on third-party lab testing to NSF protocols (it is lab-tested, not certified). The AquaTru countertop RO is the best no-install option for maximum filtration.
Does NYC add fluoride to the water? Yes. NYC has fluoridated its water since the mid-1960s and adds fluoride to about 0.7 mg/L, as directed by the city health department. Standard carbon filters like Brita do not remove fluoride. If you want to remove fluoride, you need a reverse osmosis system or an activated alumina filter. The AquaTru is certified for fluoride reduction; APEC lists fluoride among the contaminants its ROES-50 RO system reduces, though its certification covers total dissolved solids rather than fluoride specifically.
