Clean, great-tasting drinking water right at your sink. Five stages of filtration remove up to 99% of contaminants — including lead, fluoride, PFAS, and chlorine.
The most affordable way to get genuinely clean drinking water. Installs under your existing sink and delivers purified water through a dedicated faucet.
Installs neatly under your kitchen sink. Out of sight, always accessible.
Removes lead, chlorine, fluoride, nitrates, arsenic, PFAS, and hundreds more.
A separate faucet at your sink gives you pure drinking water on tap, any time.
Filters swap out in minutes. No tools, no mess, no service call required.
Each stage targets different contaminants so nothing slips through.
Catches sand, silt, rust, and particles down to 5 microns
Removes chlorine, taste, and odor from your water supply
Further reduces chloramines, VOCs, and chemical contaminants
Removes up to 99% of dissolved solids, heavy metals, and PFAS
Final polishing stage — removes any remaining taste or odor
Filter Schedule: Stages 1–3: every 6–12 months. RO membrane: 2–3 years. Post carbon: annually.
Yes. The EWG found 11 contaminants above health guidelines in Raleigh's water supply — including PFOS, trihalomethanes, haloacetic acids, and Chromium-6. A 5-stage reverse osmosis system removes over 99% of PFAS, over 99% of lead, 90–95% of nitrates, and virtually all dissolved solids that pass through the RO membrane, including most disinfection byproducts. For Raleigh homeowners who want clean, safe drinking water from the tap, the 5-stage RO is a proven, affordable solution. The only area where it differs from the 7-stage is alkaline remineralization and UV sterilization — important for some households but not essential for city water.
Yes. The RO membrane removes approximately 90–96% of fluoride from drinking water. Raleigh adds fluoride to its water supply at around 0.7 mg/L, within the range recommended by the CDC for dental health. If you prefer to minimize fluoride exposure — for infants, specific health reasons, or personal preference — the RO system will effectively reduce it. Worth noting: the 5-stage RO removes most minerals from water, so the water will have a lower TDS (total dissolved solids) than tap water. If you want minerals added back, the 7-stage HW800 AlkaPro with its alkaline remineralization stage is worth considering.
The 3.2-gallon pressurized storage tank stores purified water until you need it, then delivers it through the dedicated faucet on demand. The tank is roughly the size of a small basketball and sits upright under your kitchen sink. Most sink cabinets accommodate it with room to spare, even alongside the filtration unit and tubing. The tank holds enough water for most household drinking and cooking needs for a day — as you draw water, the RO membrane refills it continuously. If your cabinet space is tight, we can discuss alternative placement options before installation.
Stages 1–3 (sediment and carbon pre-filters) need changing every 6–12 months — typically once a year for a family of 4. The RO membrane lasts 2–3 years before needing replacement. The post-carbon polishing filter (stage 5) is replaced annually. Filter replacements are available through us or from standard suppliers. We include a maintenance schedule with every installation and provide lifetime phone support so you're never guessing about when to change filters. Annual maintenance is something most homeowners handle themselves in about 15 minutes — no tools required.
Yes, and it makes a noticeable difference. Coffee and tea taste significantly better without chlorine, minerals, and contaminants. You can connect the RO system to a refrigerator ice maker or water dispenser with an additional line — we do this regularly during installations in Raleigh homes. The only exception is if your refrigerator uses a built-in filter on the line — in that case, you'd bypass it since the RO already handles filtration. The faucet we install at the sink is the primary draw point, but connecting to an ice maker is a common add-on.
Same-week installation, lifetime warranty — no obligation.
