BEST RO SYSTEMS WE INSTALL (GOOD / BETTER / BEST)
GOOD
UNDER‑SINK (TANKED)
"Best Reverse Osmosis System Under Sink"
What it is:
Classic reverse osmosis drinking water system with a reverse osmosis storage tank (≈2–4 gal) feeding a dedicated RO faucet; can tee to the fridge/ice maker.
Why it's great:
- Fast first‑glass flow
- No continuous power needed
- Proven reliability
Typical stage stack:
Sediment → Activated Carbon → RO membrane → Carbon post‑filter → Optional remineralization
Certifications:
NSF/ANSI 58 for RO performance (TDS reduction baseline ≥75%)
BETTER
TANKLESS (COMPACT)
Our Team Favorite
What it is:
Sleek tankless reverse osmosis system that produces water continuously. Requires continuous power under the sink.
Speed tip:
We add a mini‑tank so your first 1–2 glasses pour quickly, then it reverts to on‑demand production.
Representative specs:
- ~600 GPD capacity
- ~0.4 GPM delivery
- 0.0001 μm membrane precision
- Auto‑flush & 1.5:1 low drain ratio
BEST
TANKLESS + REMINERALIZATION + WHOLE HOME FILTRATION/SOFTENER
Whole-Home Filtration + Softening
(Point of Entry)
- 10×54 whole-home water filtration/softening system installed where water enters the house.
- Removes chlorine/chloramine, reduces hardness minerals, and cuts down on other contaminants for every tap.
- Benefits: no more chlorine showers, less scale on toilets, tile, and glass.
- Dermatologists recommend whole-home filtration + softening for healthier skin and hair.
Tankless RO with Remineralization
(Point of Use)
- Compact tankless RO system under your sink, finished with alkaline post-filter for taste and balance.
- Optional mini-tank or booster pump available for homes with low water pressure.
- Certified performance: NSF/ANSI 58 (RO performance) and NSF/ANSI 372 (lead-free materials).
WHAT NASHVILLE AREA WATER REALLY MEANS FOR FAMILIES
- • Chlorine by-products (TTHMs & HAA5) are present at levels up to 90–100× higher than health guidelines (per EWG).
- • Nashville has confirmed 2,800 lead service lines, with 76,000 more still under review.
- • Hard water from our limestone geology leaves scale on dishes and appliances.
Legally safe ≠ optimal. That's why families add RO at the tap.

INSTALLED COST & FINANCING — HOW MUCH DOES A REVERSE OSMOSIS SYSTEM COST?
Middle Tennessee
We keep pricing straightforward. Your exact reverse osmosis system cost depends on choices like tanked vs tankless, remineralization, mini‑tank, booster/permeate pump, and whether electrical is needed under the sink.
WHAT THIRD‑PARTY SOURCES SAY (HELPFUL BENCHMARKS)
We'll show you all‑in local pricing before work begins. Ask about payment options or financing if you prefer to spread out the investment.
Financing can take the monthly cost down to as low as $25-$100 a month.
FILTER & MEMBRANE REPLACEMENT — REVERSE OSMOSIS MAINTENANCE
FILTER REPLACEMENT
Sediment & carbon: every 6–12 months (protect taste and the membrane). We set reminders and can handle it for you.
CDC recommends following the manufacturer's schedule and notes that people with weakened immunity shouldn't change filters themselves.
Typical filter costs: National guides list $20–$100 for replacement filter sets, depending on brand and stage count.
MEMBRANE REPLACEMENT
Reverse osmosis membrane replacement: Typically multi‑year when protected and maintained.
WaterSense includes a membrane‑life requirement (labeling ensures baseline longevity) and requires ≥75% TDS reduction in testing.
PROFESSIONAL INSTALLATION — "REVERSE OSMOSIS SYSTEM INSTALLATION NEAR ME"
WHAT'S INCLUDED
WHY WE DON'T PUSH WHOLE‑HOUSE RO (AND WHAT TO DO INSTEAD)
Whole‑house reverse osmosis systems are factory‑grade: storage tank + re‑pressurization + strict pre‑treatment. They're expensive and complex for city water.
National guides put whole house reverse osmosis system cost in the $4,800–$20,000 range installed.
OUR RECOMMENDATION
For Middle TN families, you'll get nearly all the benefits by pairing a softener/whole‑home carbon with a reverse osmosis system for home at the kitchen—simpler, 10× less, and easier to maintain.
Whole-House RO
$4,800–$20,000
Complex maintenance
Factory-grade equipment
Softener + Under-Sink RO
~$3,350 typical
Simple maintenance
Same benefits, 10× less cost

KEY SPECS THAT MATTER
GPD (GALLONS PER DAY)
Rate at standardized conditions; tanked = fast first pours from storage, tankless = continuous production.
TDS REDUCTION & CERTS
Look for NSF/ANSI 58 (baseline ≥75% TDS reduction); WaterSense® adds efficiency and membrane‑life and requires the waste‑to‑treated ratio on the label.
STAGES
Sediment → Carbon → RO membrane → Carbon → optional remineralization (taste/pH).
WASTE RATIO
Older units ran 3–4:1; modern designs (like our 600‑GPD tankless) list ~1.5:1. WaterSense‑labeled models must be ≤2.3:1.
ADDITIONAL CONSIDERATIONS
BOOSTER / PERMEATE PUMP: We add these when pressure or layout calls for it.
5‑STAGE REVERSE OSMOSIS SYSTEMS: Stage count matters less than certified performance and maintenance.
