Our small office of five people needed a practical and convenient water filtration system since our setup couldn’t accommodate a traditional under-sink RO water filter. After exploring various options, we chose this countertop water filter machine — and it has been the perfect solution! The machine is compact and fits seamlessly into our small kitchen. It’s incredibly easy to use: simply pour tap water into the tank, and it instantly provides clean, RO-filtered water. The convenience and user-friendly design make it a great fit for everyone in the office. One standout feature is the large screen with a TDS indicator, which offers real-time updates on water quality. This provides peace of mind, knowing the water we’re drinking is safe and clean. Additionally, it dispenses alkaline, mineralized water with just one touch. The machine also caters to various preferences by providing cold, room-temperature, and hot water, meeting the diverse needs of our team.. Mark T.. Lauderdale, FL. Fri Jan 31 2025

This tank provides up to 60 cups of steaming hot, filtered water per hour.

This is a terrific little system! I am a tea drinker and my husband let it slip that the UK has hot water on demand in many places... I asked if we could and lo and behold! Installation was easy*, although we didn't use the supplied filter as we have it going through a filter system already. The temperature isn't exact, so we did have to mess with the dial a little. It doesn't take up room underneath the cabinet either. *There's a crimp piece required. The metal one didn't fit properly, and they provided a plastic one also which worked, but barely..

Reverse osmosis (RO) systems can be bulky, and difficult to install, and many require electricity and pumps to operate. Most importantly, conventional RO systems are extremely inefficient wasting up to 24 gallons of water for every gallon of drinkable water! Additionally, the circle RO water filter eliminates any need for electricity by integrating the tank and filters. The Brondell H2O+ Circle RO water filter’s exclusive patented smart valve and unique circular reservoir design are the keys to its efficient design. This technology eliminates back-pressure on the RO membrane filter, reducing wastewater to less than 2 gallons for every gallon of drinking water – over 10 times more efficient than many conventional RO systems. The Circle’s refill rate is more than twice as fast as non-electric systems and equally as fast as those with electric pumps. It offers simplified installation and maintenance with features such as auto-flushing, twist, and lock filter changes, and “quick-connect” connections. The Brondell H2O+ circle RO water filter delivers water savings, power savings, and space savings all in a beautiful simplified design. The circle reverse osmosis water filtration system utilizes four separate water filters dramatically reducing industrial chemicals, heavy metals, pesticides, herbicides, total dissolved solids (TDS), volatile organic compounds (VOCs), microorganisms, bad tastes, and odors. The circle is the fastest, easiest, most elegant, and most efficient high-quality reverse osmosis system available for a healthy home and family.

Feel confident with every sip that you are getting nothing but the best for you and your family. The KOHLER® Aquifer two-stage water filtration system effectively reduces contaminants including bacteria, virus, lead, mercury, chlorine and pharmaceuticals in your cold water. While many other systems use coal-based media filters, Aquifer uses two recyclable filters: a carbon block filter made of ground-up coconut shells and a filter made of hollow fiber membrane. Under-sink installation is fast and easy, and the compact Aquifer+ system fits alongside garbage disposals and household items stored below the sink.

Installed the system relatively easy. Had to go to a plumbing store to buy different parts to connect to my beverage faucet that was not a Kohler faucet. The only thing that was inconsistent was the picture on the site shows a brass T fitting and the unit comes with a plastic T fitting. This is somewhat deceiving for the price you pay for the unit. But the end result is that the filtering system dispenses great tasting water. Both me and my wife are overall happy with the unit.. Mel T. Mon Mar 23 2026

Upgrade your kitchen with the Dual Handles Commercial Pull-Down Kitchen Faucet – the ideal solution for all your water needs. This two-handle drinking kitchen faucet seamlessly blends the advantages of a commercial-grade pull-down faucet with the convenience of an integrated drinking spout, creating a three-in-one design that streamlines your kitchen's appearance while granting you the full functionality you desire. The 360° rotating spout enhances your kitchen experience, granting effortless access to every corner of the sink. Whether you require regular hot and cold water or prefer a separate faucet for drinking water, this dual-handle kitchen faucet fulfills all your requirements.

The beverage/spring water faucet is great - strong water flow. It keeps a bubble at the tip but it doesn't drip. I kept a cup under it and it kept dry with no leaks. The main faucet sprayer has 3 functions: regular flow of water, spray flow and best of all, a super sprayer. It really removes the stubborn stuff. That was an unexpected, happy benefit. It was super easy to install. It had blow-up diagrams in the instructions so you see the order for the placement of washers etc.. Carol. Thu Apr 16 2026

So far I do like this it does make the water taste a lot better. Its not quite as cold as I would like I have a 32 oz water bottle and Im about halfway of filling it the water gets warm since its refilling the tank as it goes, but some ice cubes would fix that. I have noticed the machine is getting a little bit louder so I will monitor that and see if it gets worse but so far so good. Karlie. Syracuse, UT. Sun May 31 2026

Replaced my Culligan system with this and am very happy with the change. Had my plumber install it with new Kohler faucets in a kitchen remodeling project and it works great. I added a separate bar faucet that matched my sink faucet - which is also on a different Kohler filtration system. Filters are easy to order and replace every 6 months. Overall, very pleased and way cheaper than other solutions.. Anonymous. Fridley, MN. Tue Oct 21 2025
