Arsenic Water Filter

The CB-As series of Drinking Water Systems offers versatile and exceptional water treatment performance.

The CB-As expands upon CB Tech’s industry-leading solid carbon block water filters by serving not only as a water filter of aesthetic and health contaminants but also as an arsenic removal filter. This arsenic water filter effectively reduces the presence of Arsenic V in drinking water. The carbon block water filter is easy to change, does not waste water, does not require power, and does not require additional chemical additives.

Stringently tested to meet NSF/ANSI certification, this arsenic filter system’s housing is constructed of durable stainless steel.

Dual-hose Diverter Valve

Countertop Kit  •  MODEL: CBK2

The CB-As with countertop kit is a highly effective arsenic water filter that sits on your countertop next to the sink. It connects to your existing faucet with no tools required using the supplied hose and diverter valve, providing you with convenient access to fresh, clean drinking water when you want it. You can easily switch from filtered to unfiltered water at the push of a button.

CB-VOC Countertop Drinking Water System

Below Sink Kit  •  MODEL: CBK1

The CB-As with below sink kit installs below your sink and provides convenient access to fresh, clean drinking water whenever you want it. This under-sink arsenic water filter uses its own specially designed drinking water faucet that is installed directly on your sink top, requiring little space.

You can choose to either set the versatile filtration system on cabinet floor or mount it to the cabinet wall. You may also connect it to an icemaker using an icemaker tee fitting, and the system may be converted to a countertop system with the purchase of a conversion kit (icemaker tee and countertop conversion kit not included).
