Pentair CBR2-10 10" Carbon Block Filter – Lead, Heavy Metals, Chlorine & Cyst Reduction | Osmotics UK

Upgrade your reverse osmosis or drinking water system with the premium Pentair CBR2-10—an advanced multi-media carbon block cartridge engineered for superior reduction of lead, dissolved heavy metals, chlorine taste & odour, cysts (Cryptosporidium/Giardia), MTBE, VOCs, and other contaminants common in UK tap water. Manufactured with powdered activated carbon (PAC) and a specialized adsorbent media for targeted heavy metal capture, this filter combines chemical adsorption with mechanical filtration (nominal 0.5 micron) to deliver safer, cleaner, better-tasting water.

Protected by Pentair's unique Endurawrap™ polyolefin bilaminate prefilter, it traps sediment that clogs standard carbon blocks—extending useful life significantly compared to basic cartridges. Ideal as a dedicated heavy metal removal stage in RO/DI setups (pre- or post-membrane) or standalone in under-sink/point-of-use housings for households concerned about lead pipes, old plumbing, or urban water quality.

Key Benefits

• Heavy metal & lead protection — Reduces dissolved and particulate lead, mercury, and other metals for safer drinking water.
• Comprehensive contaminant reduction — High-capacity chlorine taste & odour removal (>20,000 gallons @ 1 GPM), plus cysts (99.95% Cryptosporidium/Giardia), MTBE, VOCs, and more.
• Extended cartridge life — Bilaminate prefilter prevents premature plugging from sediment, outperforming standard blocks in real-world use.
• Crystal-clear taste — Eliminates chemical aftertastes and odours for refreshing water straight from the tap.
• Reliable performance — Low pressure drop, high dirt-holding capacity, and robust construction.

Specifications

• Size: Standard 2.5" diameter × 9.75–10" length (fits most 10" slimline housings)
• Filter Type: Bonded powdered activated carbon (PAC) multi-media block with adsorbent media
• Micron Rating: Nominal 0.5 micron
• Initial Pressure Drop: ~0 psi @ 1 GPM
• Chlorine Taste & Odour Capacity: >20,000 gallons @ 1 GPM
• Lead Reduction: Effective through ~2,000 gallons (manufacturer internal testing; not NSF-certified for lead)
• Temperature Range: 40–165°F (4.4–74°C)
• Certifications: Tested and Certified by NSF International to NSF/ANSI Standard 42 for material and structural integrity only (not performance claims like lead reduction)
• Manufacturer: Pentair / Pentek
• SKU: CBR2-10

Compatibility

Fits standard 10-inch RO filter housings (double open end/DOE). Commonly used in Osmotics heavy metal removal systems (2-stage/3-stage kits), as a post-carbon polishing stage in RO units, or standalone for lead-prone areas. Not for high-flow whole-house (consider Big Blue equivalents).

Recommended Replacement Schedule

• Replace every 6–12 months or after ~2,000–5,000 gallons for lead/heavy metals (sooner in high-contaminant water); CTO capacity supports up to 20,000+ gallons.
• Monitor: Taste/odour return, reduced flow, or periodic lead testing (use home kits).
• In UK areas with older pipes: Prioritize 6-month changes.

This high-performance Pentair CBR2-10 cartridge offers advanced protection against lead and heavy metals in one reliable filter—trusted for RO upgrades, under-sink drinking systems, and health-conscious homes.
