Multi-Pure® Carbon Block Water Filters

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 an NSF-certified long reach faucet and 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--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 NSF-certified long reach. If you prefer an alternative, pick one from our faucet page. There’s no charge for the substitution. If ordering online, just tell us which faucet you want in the cart’s comments section. (The easy way is to use our part number to describe the faucet.)
