Whole House Water Filtration System in Greensboro
Greensboro’s Home Water Treatment Team Since 1974
Most Greensboro homeowners don’t think about their water until something’s wrong: scale on faucets, a chlorine smell in the shower, or a water heater failing ahead of schedule. A whole-house water system treats water at the point of entry, so every tap, appliance, and fixture receives treated water. Johns Plumbing, Heating & Air Conditioning, Water Purification and Electrical delivers these solutions through our sister company, Dr. Johns H2O Water Purification, which has focused exclusively on water treatment since 2002 as an authorized Kinetico dealer serving the Triad.
Together, the Johns family of companies has served Greensboro and the broader Triad community since 1974, reaching more than half a million customers over that span. Our team is fully licensed and insured, we answer the phone 24/7, and we offer same-day and emergency service throughout the area. Financing is available with approved credit, including monthly payment options and special terms promotions.

The right solution depends on what’s actually in your water supply. That’s why Dr. Johns H2O starts every project with a free water analysis before recommending any system. Municipal and well water carry different contaminants, and no two households face exactly the same conditions.
Whole House Water Filtration
Point-of-entry filtration is designed to address sediment, chloramines, and other contaminants before they reach any fixture or appliance in your home.
Whole House Water Softener
Water softening uses ion exchange to remove calcium and magnesium, the minerals responsible for scale buildup on pipes, fixtures, and water-using appliances.
Reverse Osmosis Systems
Reverse osmosis can reduce dissolved solids and a broad range of contaminants at the point of use, delivering highly purified water for drinking and cooking.
UV Treatment
UV systems are designed to neutralize bacteria and viruses without adding chemicals, making them a valuable option for well water customers.
Chloramine-Reducing Systems
Standard carbon filters don’t always reduce chloramines effectively. Dr. Johns H2O offers systems designed specifically for this challenge.
Drinking Water Systems & Water Testing
Standalone drinking water solutions and professional water analysis and testing are also available for homes with more targeted concerns.
Kinetico systems, which Dr. Johns H2O carries as an authorized dealer, run on the kinetic energy of moving water rather than electricity, so they can keep working during a power outage with no electrical components to fail. Dedicated pages covering each system type are available throughout this section of our site for homeowners who want to go deeper on any individual solution.
