A more efficient system for sustainably filtered water.
Circle’s sleek, high-capacity design includes patented, water-saving technology that makes it up to 10x more efficient than conventional reverse osmosis (RO) systems. Over the life of the product, Circle pays for itself in water savings compared to traditional RO.
A unique, flexible reservoir and patented Smart Valve reduce wastewater output by helping to eliminate back pressure—the biggest source of waste in RO systems.
Circle’s surprisingly small footprint leaves storage space available under your counter. Easy to install and maintain, it's an elegant and efficient reverse osmosis system for the modern, sustainable home.
Circle reduces these contaminants—and more.
Aesthetic chlorine, atrazine, barium, benzene, cadmium, chlorobenzene, copper, cysts, DCPB, endrin, fluoride, hexavalent & trivalent chromium, lead, methoxychlor, pentavalent arsenic, radium, trihalomethanes, and 2,4-D.
A smarter, space-saving design.
With a design that’s as attractive as it is sustainable, Circle features a rapid refill rate that allows it to fill in about half the time of traditional RO systems. Its reservoir is contained within a beautifully designed, single case that tucks below your sink—so all you’ll see is the designer faucet with LED filter-change indicator next to your tap.
Planet-friendly performance.
Most RO systems operate at a low level of efficiency, producing up to 24 gallons of wastewater for every gallon of filtered water produced. Why? When a glass of water is drawn, the system will then try to “top off” the reservoir. Because significant back pressure has built up in the almost-full reservoir, it’s difficult for new water to enter. Instead, gallons of water are pushed back down the drain before a single gallon is produced for drinking. Thanks to Circle’s patented components and innovative design, this back pressure is no longer an issue—making the Circle up to 10x more efficient over traditional RO systems.
The Circle’s refill rate is more than twice as fast as other non-electric systems, and equally as fast as those utilizing electric pumps. With long-lasting filter lifespans and easy “twist-and-seal” filter changes, Circle delivers water savings, electricity savings, and space savings—in a beautiful, simplified design.
Four-stage filtration.
The Circle utilizes 4 separate advanced filters, reducing industrial chemicals, heavy metals, VOCs, dissolved solids, bad tastes, odors, and more. See Performance Data Sheet for full list of contaminants reduced.
