Purified Water at Every Kitchen Tap

Drinking Water Purification Systems in Charlotte and surrounding areas for homes seeking cleaner, better-tasting water at point of use

Municipal water treatment and whole-house filtration address broad contamination, but drinking water purification systems target the specific quality standards people expect for water they consume directly. Ultra Blue Hydrology installs under-sink purification systems in Charlotte that use multi-stage filtration to remove dissolved solids, heavy metals, and microscopic contaminants that affect taste and safety. These systems connect to a dedicated faucet at your sink, delivering purified water on demand without requiring countertop units or pitcher filters that need constant refilling.


Under-sink systems route a portion of your cold water supply through sediment pre-filters, carbon blocks that remove chlorine and organic compounds, and semi-permeable membranes that reject dissolved solids down to 0.0001 microns. Purified water is stored in a pressurized tank under the sink so it is available immediately when you open the dedicated faucet. Rejected contaminants and minerals flush to the drain line, which maintains membrane cleanliness and extends system life.


Arrange a consultation to review purification system options and installation requirements for your kitchen configuration.

What You Notice Once Purification Is Finished


Drinking water purification combines physical filtration with molecular separation: sediment filters remove particles, carbon stages adsorb chemicals, and allow only water molecules to pass while blocking larger dissolved minerals and contaminants. The membrane operates under household water pressure, forcing water through microscopic pores while concentrating rejected material into wastewater. Systems include automatic shutoff valves that stop production when the storage tank reaches capacity, preventing water waste.


Water from the purification faucet tastes noticeably cleaner because chlorine, sulfur compounds, and dissolved minerals that carry flavor are removed during processing. Ice cubes freeze clear instead of cloudy because dissolved air and minerals are eliminated before freezing. Coffee, tea, and cooking benefit from purified water because flavor compounds are not competing with chlorine or mineral tastes, and beverages prepared with purified water appear clearer in the glass.


Purification systems require filter stage replacement on a schedule that varies by component: sediment pre-filters typically need changing every six months and carbon blocks annually depending on incoming water quality and usage volume. Some systems include indicator lights or flow sensors that alert you when replacement is due based on actual water processed rather than elapsed time.

What Property Owners Usually Ask

Questions about drinking water purification typically focus on what the system removes, how it compares to other options, and what maintenance involves over time.

  • How does under-sink purification differ from refrigerator water filters?

    Under-sink systems use multi-stage filtration to achieve higher contaminant reduction than single-stage refrigerator filters, and they supply a dedicated faucet with greater flow capacity than refrigerator dispensers. Refrigerator filters primarily remove chlorine and large particles. 

  • Why does a purification system produce wastewater during operation?

    Reverse osmosis requires flow across the membrane surface to prevent concentrated contaminants from clogging the membrane pores, so a portion of incoming water flushes rejected minerals and particles to the drain. Efficiency ratios typically range from 3:1 to 5:1 wastewater-to-purified water, depending on membrane type and incoming water pressure.

  • How much storage capacity does the under-sink tank provide?

    Residential purification systems typically include 2-4 gallon pressurized storage tanks that maintain 6-8 psi of delivery pressure to the dedicated faucet. The tank refills automatically as purified water is used, with production rates of 50-75 gallons per day depending on membrane size and incoming water pressure.

  • What installation space is required under a kitchen sink in Charlotte homes?

    Standard under-sink systems require approximately 15 inches of width and 16 inches of height for the storage tank and filter housings, plus access to a cold water supply line, drain connection, and clearance to drill a hole for the dedicated faucet. Installation typically takes two to three hours including connections and system flushing.

Ultra Blue Hydrology installs drinking water purification systems with components matched to your incoming water quality and household consumption patterns, ensuring optimal performance and maintenance intervals.
