How Does This Compare?
SOUTHAMPTON (18966) has 288 recorded violations, including 7 health-based. 4 remain unresolved. Consider testing your tap water independently for added peace of mind.
Recommended Water Filters
Based on the contaminants detected in your area, these filter types may help improve your water quality.
Reverse Osmosis System
Highly effective at removing heavy metals, dissolved solids, and a wide range of contaminants. Recommended for homes with lead or arsenic concerns.
Targets:Lead, Copper, Arsenic, Mercury, Cadmium
Look for:NSF/ANSI 58 certified
Activated Carbon Filter
Excellent for removing chlorine, chloramine, and disinfection byproducts like THMs and HAAs. Available as pitcher filters, countertop, or under-sink units.
Targets:THMs, HAAs, Chlorine, Chloramine, Taste & Odor
Look for:NSF/ANSI 42 & 53 certified
UV Water Purifier
Uses ultraviolet light to neutralize bacteria, viruses, and parasites without chemicals. Ideal for homes with microbial contamination concerns.
Targets:E. coli, Coliform, Giardia, Cryptosporidium
Look for:NSF/ANSI 55 (Class A) certified
Always look for filters certified by NSF International for the specific contaminants you want to remove.
