DESCRIPTION
Meet the RO system that's smarter than your old water filter and probably your old phone.
The Waterdrop G3 is a tankless, multi-stage reverse osmosis system that makes up to 400 gallons of purified water a day at a 1:1 pure-to-drain ratio. It reduces TDS, chlorine, chloramine, PFAS, lead, and other heavy metals, and it's certified to NSF/ANSI 58 and 372.
The smart faucet shows real-time water quality, and filter life indicators tell you when to swap.
Pure water, plus receipts.
HOW TO USE
- Install it under the sink. Hook up the cold water line, drain line, and smart faucet, then plug it in.
- Flush the filters as directed.
- Pour. Check the faucet display for real-time water quality.
- Replace filters when the indicator lights tell you to.
HOW DOES IT WORK
Water passes through sediment and activated carbon filters first. They catch particles and chlorine to protect the membrane.
Next, a built-in booster pump pushes water through the reverse osmosis membrane, which blocks dissolved solids, heavy metals, and other contaminants at the molecular level. A final carbon stage polishes taste.
The faucet's TDS readout shows you what's coming out. No tank means no stored water sitting around. Just fresh, purified water whenever you turn the handle.
Science you can see.

Get Ideal Drinking Water
Standard tap water carries hundreds of Total Dissolved Solids — most homes have no idea how many are actually in their drinking water.
What are TDS :
- Inorganic salts, calcium, potassium, magnesium, and other minerals and cations
- Metals, nitrates, chlorides, sulfates, carbonates
- Contaminants, impurities, and toxins
Where they come from :
Natural sources like rivers and lakes, storm water runoff, agricultural runoff, sewage, urban runoff, plumbing and pipe residue, industrial waste, chemical treatment, and road deicing salt.
Safe, Healthy Drinking Water
A quality reverse osmosis system delivers genuinely ideal drinking water for your family. 0 to 50 PPM TDS is the target for ideal drinking water — and that's exactly the range this system is built to hit.
Removable Contaminants
Everyday stuff:
TDS, chlorine, taste and odor, chloramine, scale, turbidity
Carcinogens:
Chromium (hexavalent), chromium (trivalent), cadmium and cadmium compounds, ferric oxide
Heavy metals:
Lead, mercury, barium, copper, radium 226/228, aluminum.
Microorganic contaminant:
cyst
Inorganic pollutants:
Arsenic and inorganic arsenic compounds, fluoride
Organic pollutants:
Asbestos, benzene, formaldehyde, nitrite bisphenol A, trichloromethane, chlordane, PFOA & PFOS, and more
Stop Drinking Pool Water!
Many Americans are drinking 300 to 600 times above the EPA's chlorine health guidelines. More water companies keep increasing their chlorine dosage — and while it helps kill microbes, drinking it at high levels is a real health concern.
Negative chlorine health effects:
- Forms Trihalomethanes (THMs) — linked to cancer and other issues
- Eye and nose irritation
- Stomach and gut discomfort
- Dry, itchy, flaking skin and dandruff
The WaterDrop G3's NSF-certified filtration removes chlorine right along with everything else on the contaminant list above.
Note: this corrects a mismatched brand reference on the source page, which cited an unrelated SoftPro whole-house filter here instead of this product's own chlorine removal.

Chlorine & Chloramine... Not In My Water!

Negative chloramine health effects:
- Respiratory problems and increased asthma risk from chloramine vapors
- Aggravated digestive disorders
- Increased pneumonia and other influenza-related death risk
