Multi-Pure® Carbon Block Water Filters


Multi-Pure Stainless Steel, Solid Carbon Block Filters — Undersink and Countertop Models


We offer the commercial-grade stainless steel Multi-Pure, the CBVOC-SB undersink model, as well as CBVOC-SC, the countertop unit, and CBVOC-SI, the inline unit.

Commercial Multi-Pure units carry the same full NSF and California certifications as standard Multi-Pure units sold under the Multi-Pure national (MLM) marketing program.

The Multi-Pure name has been synonymous with quality since the early 1980s. The stainless steel housings on all our commercial units have Multi-Pure's unprecedented 25 year warranty. The replaceable cartridge is rated for 750 gallons (about a year in most cases) of NSF-certified performance.

You won't find a better carbon block water filter at any price.


Model CBVOC-SB
The Undersink Multi-Pure

Multi-Pure Undersink Unit, Model CBVOC-SB, comes complete with quick-connect fittings and everything you need to install.

We offer it with your choice of a Tomlinson brand “Pro-Flo” or Contemporary “Value” style ledge faucet (additional styles and finishes are available on our faucet page) and a high quality inlet saddle or adapter for flexible tubing. This is an easy-to-install, durable unit with 25 year warranty on the case. It comes with one filter cartridge. The cartridge should be changed annually. Only one cartridge will fit it: the Multi-Pure CBTVOC.

The CBVOC-SB has a unique vessel design with both inlet and outlet ports conveniently located near the bottom of the vessel. We've enhanced the classy standard Multi-Pure version by adding quick connect fittings. See the picture at right. We install John Guest-style straight fittings on the unit and include Plug-In elbows — shown installed in the picture — which give the installer the option of a straight fitting or a unique swiveling elbow. Both the elbows and the tubes simply push into the fittings— no tools needed.

The compact, stylish Multi-Pure CBVOC-SC Countertop unit, at right, uses a “return” style diverter and therefore needs no spout. When the diverter is activated with the knob, water is sent through the Multi-Pure unit and the filtered water is returned to the small outlet on the diverter valve itself. Installation is quick: just remove the current aerator from your sink faucet and replace it with the Multi-Pure diverter. An adapter pack is included to accommodate the most common faucet setups.

The inline unit (AO400 &mdash not pictured) is exactly like the undersink and countertop models, but nothing is included except the standard Quick-Connect fittings. If you want 3/8" rather than 1/4" fittings, just tell us when you place the order. Inline models are typically used to supply refrigerators, aquariums, water coolers, or other non-faucet applications.

Important note about ordering.

Undersink water filters get their inlet water from the cold water pipe that goes to the regular sink faucet. If your cold water pipe is copper, please order model SV, and we'll include a self-piercing saddle valve. If you have a flexible cold water tube, please order model EZ, and we'll include the proper adapter. This makes installation easy and saves you a trip to the hardware store.


The standard faucet is an attractive Tomlinson brand NSF-certified “Pro-Flo” or Contemporary “Value” style ledge faucet. Just select the faucet of your choice from the dropdown during checkout. We also carry additional styles and finishes on our faucet page.

CF101 Multi-Pure Stainless Steel Countertop requires no installation. Simply attach the diverter valve to your sink faucet (it will fit most faucets, and adapters are included for irregular faucet designs) and you have top quality drinking water instantly. It has the same 25-year warranty as the undersink unit, and it uses the same 750 gallon FC595 cartridge.

This is a “return” style countertop, unlike other Multi-Pure countertops. It has no spout. Water is dispensed through the diverter valve itself, which is attached to your regular sink faucet.

Multi-Pure Filter Cartridge Explanation!

If you're looking for a replacement cartridge for a standard Multi-Pure unit, DO NOT order the CBTVOC Cartridge above.

The cartridge listed above is for our commercial-grade Multi-Pure units. If you are looking for a cartridge for a standard Multi-Pure unit (Multi-Pure 500 series, Multi-Pure 400, 250 or 750, for example), you will need the Multi-Pure CB6 Cartridge (pictured at right). Please go here for an explanation and ordering instructions.
