Water Quality Report

New York Tap Water: What Should You Know?

According to the New York City Department of Environmental Protection (DEP)’s 2025 water quality report, New York City tap water meets or exceeds all drinking water standards. It’s soft water low in minerals — building plumbing is the part to watch.

A Water Purifier Before a Softener

The DEP notes that New York City water is soft to slightly hard. With less worry about scale, taste and building plumbing are the main concerns.

Chlorine Taste and Odor

New York City maintains residual chlorine throughout distribution. It’s within safety standards, but some households are sensitive to the taste and odor.

If You Rent an Apartment

Renters may need to check with their building manager before installation. Countertop models that sit on the sink are the low-hassle option.

These figures are system-wide averages published by the agencies; actual water quality at your home may vary by water provider, season, and building plumbing. Check your local water provider's annual quality report for precise figures.

FAQ

뉴욕 고객이 자주 묻는 질문

View All FAQs →

Do you install in Flushing or Manhattan too?

Yes — installation is available across New York City’s 5 boroughs, including Queens (including Flushing), Manhattan, Brooklyn, the Bronx, and Staten Island. For Westchester and Long Island, send us your address and we’ll confirm availability.

Is New York City tap water safe to drink as is?

According to the New York City Department of Environmental Protection (DEP)’s 2025 report, New York City tap water meets or exceeds all drinking water standards. However, lead can leach from plumbing in older buildings, so the DEP offers free lead test kits.

New York water is soft — do I still need a softener?

New York City water is soft at an average hardness of 32 mg/L, so most households start with a purifier. Homes on Long Island groundwater or private wells may consider a softener based on water test results.

Can I install in a rental apartment?

Most homes can be fitted, but renters should check with their building manager first. We'll recommend the right model for your home — countertop or undersink — during your consultation.

How are filters maintained after installation?

During your rental, a Coway specialist visits every 6 months to replace filters and inspect your products. Maintenance is included in your rental fee.
