Description
NSF/ANSI 42 material-certified carbon block
5-micron coconut-shell carbon block for premium taste, odor and fine-particle polishing
The PURETA HQCBC-10-5 combines activated coconut-shell carbon with a tighter 5-micron nominal rating. It is designed for compatible whole-house, under-sink and reverse-osmosis housings where enhanced chlorine-related taste and odor polishing and finer particulate filtration are desired.

What it does
Combines chemical adsorption with finer particulate polishing
The compressed carbon-block structure helps provide even water contact through the media while the 5-micron nominal rating captures finer suspended particles than a typical 10-micron carbon block.
Secondary purpose
5-Micron Final Polishing
Helps capture fine suspended particles while providing a final-stage carbon polish before water reaches the next treatment step or household fixture.
Key benefits
Premium coconut-shell media with certified material safety
Coconut-Shell Activated Carbon
Premium carbon media selected for adsorption efficiency and clean-tasting water.
5-Micron Nominal Rating
Provides tighter particulate filtration than a typical 10-micron carbon block.
NSF/ANSI 42 Material Certified
Certification applies to material requirements for the listed PURETA HQCBC models.*
Solid Carbon-Block Construction
Compressed media helps reduce channeling and supports consistent water contact.
Whole-House and RO Compatible
Fits compatible standard slim housings used in whole-house, under-sink and reverse-osmosis systems.
Final Polishing Stage
Best used after sediment prefiltration for premium taste, odor and particulate polishing.
Reduction guide
What this cartridge helps reduce

Installation and maintenance
- ✓Install sediment filtration upstream whenever suspended solids are present
- ✓Confirm the housing accepts a standard 10″ × 2.5″ cartridge
- ✓Operate within the pressure, temperature and flow limits of the complete system
- ✓Pressurize slowly and inspect the housing for leaks after replacement
- ✓Flush the cartridge until the water runs clear before normal use
- ✓Replace when taste, odor, flow or particulate performance declines
Which carbon block should you choose?
Standard, premium or certified 5-micron polishing
CTO
