Your tap water isn't as clean as you think.

Municipal treatment handles bacteria and basic contaminants — but it can't eliminate everything. Lead from old pipes, chlorine added at the plant, PFAS chemicals, nitrates, and trace pharmaceuticals routinely pass through to your glass. Reverse osmosis removes up to 99% of dissolved contaminants at the point of use, giving you genuinely pure drinking water without the plastic waste of bottled water.

5 stages. 99% pure. Under your sink.

The Aquapurion uses a multi-stage filtration sequence that removes progressively smaller contaminants — ending with a semi-permeable membrane that blocks dissolved solids down to 0.0001 microns. What's left is water that tastes clean because it actually is.

Stage 1 — Sediment Pre-Filter

Removes sand, silt, rust, and particles down to 5 microns. Protects downstream filters from premature clogging.

Stage 2 — Carbon Block Filter

Removes chlorine, chloramines, herbicides, pesticides, and other organic chemicals that affect taste and odor.

Stage 3 — Carbon Block Filter

Second carbon stage for deeper chemical removal before water reaches the membrane.

Stage 4 — RO Membrane

The core stage. Removes up to 99% of dissolved solids: lead, arsenic, nitrates, fluoride, chromium, PFAS, and more.

Stage 5 — Polishing Filter

Final carbon polish removes any residual taste before water reaches your faucet — the last step to crisp, clean water.

100% BPA-free — because the container matters too

BPA mimics estrogen in the body and can affect growth, reproduction, and hormonal function. Every component in the Aquapurion system — from the housing to the fittings — is 100% BPA-free and certified NSF and FDA approved. You're not trading plastic bottle waste for plastic plumbing.

Aquapurion reverse osmosis system installed under sink

100 gallons per day. Full 3/8″ flow to your faucet.

Most under-sink RO systems restrict flow to a trickle. The Aquapurion delivers full 3/8″ flow from the tank to your dedicated faucet — no waiting, no pressure drop. At up to 100 gallons per day, it handles heavy household use without running dry.

Pure clean drinking water from reverse osmosis

Optional permeate pump — connect to your refrigerator

Standard RO systems lose 30–40% of pressure in the process. Add the optional non-electric permeate pump and you can install the system remotely in a basement or utility room — and even connect it directly to your refrigerator or icemaker for RO-filtered ice and water.

Permeate pump option for refrigerator connection

Quick connect fittings

No special tools required. The push-to-connect fittings make installation straightforward for any competent DIYer.

3-year warranty

Full parts warranty on the system. Filter replacements are simple and affordable — a 5-stage pack runs about $52 and ships every 6 or 12 months automatically.

All-inclusive kit

System ships with faucet, all filters, membrane, and every installation part needed. Nothing extra to buy to get started.

Compact under-sink design

The sleek, space-efficient housing fits under most standard kitchen sinks without sacrificing cabinet storage.

Frequently asked questions

Reverse osmosis pushes water through a semi-permeable membrane under pressure. The membrane has pores so small (0.0001 microns) that only water molecules pass through — dissolved contaminants, heavy metals, and chemicals are blocked and flushed away. The result is water that's up to 99% free of dissolved solids.
Yes — RO water is among the purest forms of drinking water available. The process removes harmful contaminants while leaving H₂O molecules intact. The slight reduction in naturally occurring minerals is not a health concern; most minerals in your diet come from food, not water.
Refrigerator filters use carbon filtration, which removes chlorine and improves taste — but they don't remove dissolved solids like lead, arsenic, nitrates, fluoride, or PFAS. An RO system removes all of those and more, at a fraction of the long-term cost of bottled water.
Pre-filters and post-filters are replaced every 6–12 months depending on your water usage and quality. The RO membrane typically lasts 2–3 years. We offer automatic filter delivery so you never forget — a 5-stage replacement pack ships for about $52.
Yes, with the optional permeate pump upgrade. The pump maintains pressure even when installed remotely and allows a direct connection to your refrigerator or icemaker — giving you filtered RO water and ice throughout your kitchen.
Yes, and they complement each other well. The softener protects your whole home from hard water scale; the RO system provides purified drinking water at your kitchen tap. If sodium from softening is a concern, the RO membrane removes it along with everything else.

Crystal clear water, no more bottles
“We stopped buying bottled water the week this was installed. The water tastes noticeably cleaner — no chlorine aftertaste at all. The faucet looks great. Could not be happier.”

Best kitchen upgrade we’ve made
“I was skeptical but after testing our tap water and seeing what was in it, we pulled the trigger. The Aquapurion is quiet, compact, and the water pressure is excellent. My coffee tastes completely different now.”

Added the permeate pump — game changer
“Got the permeate pump upgrade and connected it to our refrigerator. Now our ice and water dispenser runs on RO water. The pressure is great and we haven’t bought a bag of ice since. Worth every penny.”
