Change water.Change the world.
Our patented filter system pulls forever chemicals (PFAS) and microplastics out of water until lab tests can't find any. Then we bottle it in glass.
How small is clean
Down to a ten-thousandth of a micron.
Remedion's filters start at five microns and finish at one ten-thousandth of a micron, smaller than a virus and down at the scale of a single chemical molecule. Every step down this chart is ten times smaller.
Approximate typical sizes. Filter range from Remedion's technical deck.
The system
Four stages. Nothing added.
Water passes through four mechanical stages, each catching something the last one can't. No chemicals are added, and the same design scales from a countertop to a whole community.
Sterilise
Kills bacteria and viruses.
Capture
Catches sand, sediment and particles.
Absorb
Pulls out chemicals like PFAS and VOCs.
Separate
Removes microplastics and heavy metals.
What comes out: just water. Nothing else detected.
The proof
Detectable in. Non-detect out.
Same water, tested before and after the filters. Drag across the microscope plate to compare.
BeforeAfter
Forever chemicals, measured in and out
In plain terms: the water going in carried traces of PFOA and PFOS, the two forever chemicals the EPA now limits in U.S. tap water. After the filters, the lab couldn't find them, or any of the other 16 it tested for.
EMSL Analytical, EPA Method 537.1. "Not detected" means below the lab's reporting limit. Input values are lab estimates below the reporting limit.
The vessel
Plastic bottles shed plastic into your water. Glass and cork don't.
In a 2024 Columbia University study of three popular brands, researchers counted about 240,000 plastic particles in a liter of plastic-bottled water, nine in ten of them nanoplastics. Nothing plastic touches CUP WTR by Remedion: not the filters, not the bottle, not the cork.

Four systems · one water
One train. Everything it feeds.
The same clean water that fills the bottle can grow food, raise seafood and help make power. Choose a system to see the difference.
Nothing plastic touches your water
Purified water goes straight into glass with a natural cork. That's CUP WTR by Remedion, the first product off the line.
- No PFAS or microplastics detected on third-party panels
- Glass bottle, natural cork, recycled carrier
- Plant rated for 1,600 cases a day in Warwick
Clean water in, clean food out
Whatever is in the water, a crop takes up. In a Deep Water Culture farm, roots hang in purified water instead of soil.
- Indoor, soil-free and pesticide-free
- Rice, greens, herbs, tomatoes, peppers, berries
Seafood raised in clean water
Fish grow on land in indoor tanks of purified water, away from the runoff and plastic drifting in open water.
- Tilapia, salmon, trout and shrimp
- Oysters, clams and mussels held in clean water to purge before sale
The water it cleans helps make power
As cleaned water leaves the system it spins a turbine, and that electricity flows back to help run the purification.
- Less power drawn from the grid
- Built into the community-scale design
The thesis
You are what you drink.
Every layer of the food supply is built on water. Whatever the water carries, crops take up, animals pass along, and the plate delivers. You can't clean a pyramid from the top.
Water first. Then the whole pyramid.

Questions, answered
Water, plainly explained.
What is CUP WTR?
CUP WTR by Remedion is purified still water bottled in 25.4 oz glass with a natural cork, sold six to a recycled carrier. The name stands for Clean, Unpolluted, Pure Water. It is made by Remedion in Warwick, Rhode Island, and is on presale while the plant is built.
Does CUP WTR contain PFAS or microplastics?
No PFAS and no microplastics were detected in CUP WTR on third-party panels run by EMSL Analytical. All 18 PFAS compounds on the EPA drinking-water panel (EPA Method 537.1) were below the lab's reporting limit after treatment.
What are PFAS, or forever chemicals?
PFAS (per- and polyfluoroalkyl substances) are thousands of man-made chemicals used in non-stick, waterproof and stain-resistant products. They are called forever chemicals because they break down very slowly in the environment.
Is there PFAS in bottled water?
Sometimes, at low levels. The FDA tested 197 bottled waters sold in U.S. stores in 2023 and 2024; ten had detectable PFAS, and none exceeded EPA limits for public drinking water. Results depend on which PFAS a lab tests for. Source: FDA, 2025
How much PFAS is in U.S. tap water?
A U.S. Geological Survey study sampled tap water at 716 locations and estimated that at least one PFAS is present in about 45% of U.S. tap water. Levels vary widely by location and water source. Source: USGS, 2023
What is the EPA's PFAS drinking water rule?
In April 2024 the EPA set the first enforceable national limits for PFAS in drinking water, including 4 parts per trillion each for PFOA and PFOS. Utilities must comply by 2029; in May 2026 the EPA proposed allowing up to 2031 for systems that request it. Source: Harvard EELP tracker
How many plastic particles are in bottled water?
A 2024 Columbia University study in PNAS counted about 240,000 plastic particles per liter on average across three popular U.S. bottled-water brands, about 90% of them nanoplastics smaller than one micrometer. Source: Qian et al., PNAS 2024
How does Remedion remove PFAS and microplastics?
Remedion uses a purely mechanical filter train with four stages: sterilise (bacteria and viruses), capture (sand and particles), absorb (chemicals such as PFAS) and separate (microplastics and heavy metals). It filters from five microns down to one ten-thousandth of a micron and adds nothing to the water.
Why glass and cork instead of plastic?
Plastic bottles can shed particles into the water they hold. Glass is inert, and France's food-safety agency ANSES traced most microplastics in glass-bottled drinks to the paint on metal caps, which is why CUP WTR uses a natural cork. Nothing plastic touches CUP WTR from the filters to the cork. Source: ANSES study, 2025
Can I buy CUP WTR now?
Yes, as a presale while the Warwick plant is built. A case of six is $20 plus freight shipped from cupwater.co, or $18 for local pickup at the plant in Warwick, Rhode Island. Subscriptions are available daily, weekly, monthly or yearly.
Where is CUP WTR made?
At Remedion's own building at 191 2nd Avenue, Warwick, Rhode Island, just south of Providence. Rhode Island has no other in-state water bottler.
Is Remedion's technology patented?
Yes. U.S. patent US-12662404-B1, a purification system with bottling apparatus, is issued. Remedion's Closed Aquaculture System patent was allowed in August 2026, and its Deep Water Culture and further bottling patents are under review.
What is Deep Water Culture?
Deep Water Culture is a hydroponic method where plant roots hang directly in oxygenated, nutrient-rich water, with plants held on floating rafts. Remedion's farm design uses purified water, indoors, with no soil and no pesticides. Source: Oregon State University Extension
What is a closed aquaculture system?
A closed aquaculture system raises fish in indoor tanks that recirculate and treat their own water instead of open ocean pens. Remedion's design raises tilapia, salmon, trout and shrimp on purified water, and holds oysters, clams and mussels in clean water to purge before sale.
It all starts with water.
