Based on the contaminants detected in your area, these filter types may help improve your water quality.

Reverse Osmosis System

One of the few filtration methods effective at removing nitrates and nitrites. Essential for households with infants.

Targets:Nitrate, Nitrite, Dissolved Solids

Look for:NSF/ANSI 58 certified

NSF Certified Products → EPA Safe Drinking Water Guide →

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

NSF Certified Products → EPA Safe Drinking Water Guide →

Always look for filters certified by NSF International for the specific contaminants you want to remove.
