We know what your thinking - what makes the Aquapurion different from other under sink reverse osmosis systems? When we began designing the Aquapurion, we wanted it to be as affordable and easy to install as possible, without making any compromise to our quality standards. Our co-founder Mark describes The Aquapurion 5 Stage Reverse Osmosis System as a critical step forward in providing people with an affordable solution to the dangers of municipal water and plastic waste. This system features:
BPA (bisphenol A) is a chemical that is added to many commercial products, including food containers and hygiene products. It was first discovered in the 1890s, but chemists in the 1950s realized that it could be mixed with other compounds to produce strong and resilient plastics.
BPA is said to mimic the structure and function of the hormone estrogen. Due to its estrogen-like shape, BPA can bind to estrogen receptors and influence bodily processes, such as growth, cell repair, fetal development, energy levels, and reproduction. In addition, BPA may also interact with other hormone receptors, such as those for your thyroid, thus altering their function.
Your body is sensitive to changes in hormone levels, which is the reason why BPA’s ability to mimic estrogen is believed to affect your health.
Most reverse osmosis systems lose 30% to 40% of their pressure during the reverse osmosis process. We prevent this by offering the option for a non-electric permeate pump that attaches to the top of our reverse osmosis system. This pump utilizes all NSF, WQA and FDA Certified components and allows you to install the system remotely in a basement or utility room. Never replace a refrigerator filter again - by adding the high-pressure pump option, you can connect your under sink RO to your refrigerator/icemaker, allowing you to enjoy a cleaner, clearer, and better-tasting ice and water experience.
1 .The Permeate Pump makes water twice as fast as an ordinary RO
2.The Permeate Pump makes higher quality water than an ordinary RO
3. The Permeate Pump wastes 80% less water than any ordinary RO
4.The Permeate Pump delivers the highest pressure at the faucet of any RO - Ideal for ice-makers that need pressure.

"This product works great. Installation was made super simple with the supplied materials, I only wish they provided more tubing to allow for easier routing under the cabinet. I had to buy more myself but it ended up working out."
— Matthew S. (5/5)
"Absolutely love the system. My granddaughters have declared this the best water they have ever tasted in their lives. I would agree."
— Jo G. (5/5)
"Seems like a very good product"
— Eric E. (4/5)
"So far, so good and the water tastes great."
— Jeff A. (5/5)
"I did lots of research and read many reviews before buying this system. Most of the popular Chinese made units were reported to be flimsy and cheap and leak prone. This thing has a very solid feel. Installed easily and color coded tubing made it easy to see what was going where. Permeate pump gives us much better volume and pressure especially for feed to fridge. The pump does make a clicking sound but not a big deal. TDS went from 460 to 70. With Nitrate filter went from off the scale to 0. I'm happy."
— Ganguet, R. (5/5)
"This seems like a well made product and once installed has dropped the lab-measured arsenic levels in our home’s water from above the limit to imperceptible. We love our water now! Unfortunately, when I ordered this product, it took far longer than anticipated to arrive. I had to make multiple frustrated phone calls to US Water Systems to get my order (which is especially frustrating when we are talking about drinking water and there are several next-day delivery options on Amazon), and it now shows as out of stock on their website. So, if you are able to purchase this system, I do recommend it. However, be weary of lead times and maybe call customer service first to check expected delivery/lead times."
— Andrew B. (3/5)
"Our old reverse osmosis system, installed when we bought our house, was never able to keep up with our demand. We wanted to connect a countertop ice maker and knew we had to upgrade. After some research we found this system with permeate pump. We chose to install it in our cellar to save under-sink space, and to make maintenance easier. The new system has no trouble keeping up with demand, including our countertop ice maker. Water quality is outstanding. My wife and daughter are very picky about their water, so as long as they're happy, I am happy."
— Jennifer S. (5/5)
"Had reverse osmosis system for 15 years. This is by far the best system I’ve had. Great water flow and best tasting water."
— Stanley T. (5/5)
"Can not say enough good things about this unit. Great cost, easy detailed installation instructions, great customer communication/support; from ordering, shipping updates to any questions regarding the system and easy self filter replacement. From a family of Master Plumbers and the importance of clean water and the cost of bottled water or expensive units, Highly recommend, not only do we use this unit for our home personal use but we also recommend to anyone looking for an alternative to getting accessible clean water."
— Kathryn H. (5/5)
"It was an easy install thanks to the installation instructions being provided. I love the flow, the faucet and how compact under the sink leaving room for my other essentials"
— Melissa l. (5/5)
