Filtration Recommendations
Based on contaminants found in health-based violations, these treatment methods are most relevant for residents.
Reverse Osmosis
Reverse osmosis (RO) is the most comprehensive point-of-use water treatment technology available for residential use.
Activated Carbon
Activated carbon is the most widely used residential water treatment technology.
UV Purification
Ultraviolet (UV) water purifiers use germicidal UV-C light to inactivate bacteria, viruses, and protozoa by damaging their DNA.
