CB-VOC: Compact. Effective. That’s the CB-VOC series. With its industry-leading solid carbon block water filters, NSF/ANSI certifications and durable stainless steel construction, the CB-VOC series delivers the safe, healthy water your home or facility demands — without wasting water or requiring chemical additives.
CB-As: Powerful. Versatile. That’s the CB-As series. With its unmatched reduction of aesthetic and health contaminants, including Arsenic V, the NSF-certified CB-As series requires zero chemical additives and prevents the waste of water.

Best Consumer Value in Under-Sink Carbon Filtration

Features and advantages of CB Tech’s CB-As and CB-VOC series include:

Cost-Effective: With the CB-As and CB-VOC series, our carbon block filters deliver long-lasting performance. On average, filters last for about a year before requiring replacement. For the CB-VOC series, that translates to processing 750 gallons at an operating cost of nine cents per gallon or 600 gallons at 13 cents per gallon for the CB-As series. Neither of these under-sink water purifiers requires a power source.
Industry-Leading Technology: Innovative submicron solid carbon block technology delivers unparalleled filtration. Both the CB-As and CB-VOC series use chemical and physical adsorption, electrokinetic adsorption and mechanical filtration, with the CB-As capable of reducing Arsenic V.
Performance-Driven: CB Tech verifies the integrity, performance and credibility of all our products. The CB Tech CB-As series carries NSF/ANSI Standard 42 and 53 certifications, while the CB-VOC series comes with NSF/ANSI Standard 42, 53 and 401 certifications.
Guaranteed: CB Tech warrants to the original retail customer its drinking water system and components to be free of defects in material and workmanship for use under normal care.
