USWF-CB5-2045 is a 5 micron 20"x4.5" carbon block chlorine and sediment reduction filter that is proudly manufactured in the USA. It is constructed of an extruded coconut carbon block covered in a polypropylene wrap.

Activated carbon block filters are excellent filters which improve on the characteristics of GAC (granular activated carbon) filters in a number of ways. Carbon blocks are pressed into a single piece of carbon with a consistent density meaning the water flow is evenly distributed throughout the carbon in the filter. This prevents channeling, fluidization and carbon bypassing that can occur in traditional GAC filters. The consistent density of the carbon block also helps control flow rate and pressure drop through the filter while maintaining contact time with the carbon to ensure excellent filtration performance. Carbon block filters also typically produce less carbon fines than GAC filters, and have the added capability of capturing sediment in addition to the carbon filtration.

USWF carbon block filters are constructed from coconut carbon. Compared to other forms of activated carbon coconut shell carbon has more surface area and a higher density of micro pores leading to an overall greater porosity. The increased porosity of coconut carbon provides increased adsorption and filtration of volatile organic contaminants which is why it is considered as one of the best materials for water filtration. Not to mention that coconut shells are considered to be the greenest most environmentally friendly sources of carbon available. It is renewable, grows year round, and doesn't harm the trees allowing for a sustainable, continuous source of high quality carbon.

This American made filter is a compatible replacement for other popular activated carbon block filters like the Pentek EP-20BB, Hydronix CB-45-2005, and more.

Instructions

  1. Turn off water supply and release pressure in the filter housing. (Press red pressure-relief button on housing if present.)
  2. Unscrew filter housing sump. (Use filter wrench if nessecary.)
  3. Discard used filter cartridge. Remove the sump o-ring, wipe clean and set aside.
  4. Wash housing with dish soap and warm water using a nonabrasive sponge or cloth. Rinse thoroughly
  5. If unpleasent odor is present disinfect filter housing. Fill 1/3 with water. Add about 1 tablespoon of bleach and scrub to disinfect. Rinse thoroughly
  6. Lubricate o-ring with clean silicone grease and place back onto the sump housing. (Check for cracks or imperfections on the o-ring while lubicating, and replace o-ring if damaged.)
  7. Insert new filter cartridge ensuring that it is seated properly in the sump housing.
  8. Screw the sump housing back onto the cap and hand-tighten. Do not use the filter wrench to prevent over tightening.
  9. Turn on the water supply and check for leaks before leaving the installation.
  10. Flush out any air from the filter housing. (Using the red pressure-relief button, or a nearby down-stream faucet.)
