Water Guardian Countertop Filter Details

This compact drinking water filter is a high performance drinking water treatment system for apartments and non-permanent installations. NSF certification verifies its outstanding filtration abilities against more than 60 types of contaminants.

It’s made in the USA by CB Tech, a health-conscious leader of the water filtration industry. CB Tech has repeatedly initiated breakthroughs in carbon block technology for residential drinking water filters for almost 40 years.

Outstanding Benefits

  • Micro-filtration (0.5 microns)
  • Does not strip healthy minerals from your water
  • Wastes no water
  • NSF certified for reduction of over 60 contaminants including:
  • Chlorine and THMs
  • Chloramine
  • Lead and Mercury
  • PCBs and VOCs

Exceptional Features

  • Dual return diverter valve
  • Installs in minutes
  • Five year warranty

Simple to Install, Convenient to Use.

The unit comes with a dual return diverter valve which attaches to the end of your tap. This makes it easy to toggle between your choice of filtered or unfiltered water.

The dual return feature gives you flexibility about where you position the water filter – it does not have to sit right beside the sink because a discrete second hose brings filtered water back to your tap.

NOTE: Certain types of pull-out kitchen faucets won’t accommodate a diverter valve, a requirement for countertop installation.

NSF-Certified for Exceptional Protection and Performance

The Water Guardian cartridge is a specially activated carbon block filter certified by NSF to reduce a wide range of contaminants including those known to occur in Metro Vancouver tap water, such as Chlorine, THMs, Cysts and Lead.

The CBT-VOC filter cartridge accomplishes this by directing every molecule of water through microscopic pores (0.5 micron) and by utilizing the triple-action protection of mechanical filtration, electrokinetic adsorption, and physical adsorption.

The filter is also certified to reduce chloramine – a challenging (to remove) disinfectant used in communities like Victoria, Abbotsford and Mission, BC.

Cartridge Replacement and Email Reminder Service

The Water Guardian cartridge is called the CBTAD. It uses advanced solid carbon block filtration technology that combines mechanical filtration, electrokinetic adsorption, and chemical/physical adsorption.

For contaminants reduced by adsorption, filter life/capacity is 750 gallons. However, filter life will vary in proportion to the amount of water used and the level of impurities in the water being processed.

The CBT-VOC cartridge is engineered so that contaminants removed by mechanical filtration, such as turbidity, will cause the flow rate to decrease – an indicator that the cartridge should be replaced. We recommend changing it when the first of the following occurs: (a) after approximately 9 months of use; (b) 750 gallons of use; (c) the flow rate diminishes.

watermatters provides a free email reminder service that will notify you when your cartridge is due for replacement.

Filter Housing

Polypropylene, a stable non-leaching plastic – the industry standard for drinking water filters.


10½” (27 cm) H, 5¾” (14.5 cm) D, 9” (22.5 cm) W

Five year warranty

(Does not include cartridges which by nature are exhausted by the contaminants they are designed to filter.)

Drinking water filters are for cold water use only.

Use only on municipally treated water or other supply known to be microbiologically safe.
