Carbon Block Whole House Filter Cartridge 4.5" x 10" Big Blue 1 Micron, PFAS Certified

Description

This NSF-certified PFAS carbon block filter cartridge is designed to reduce PFOA and PFOS “forever chemicals” from drinking water at the point of use. Sized to fit standard 4.5″ x 10″ Big Blue housings, it provides an affordable, easy-to-replace solution for under-sink and small residential filtration systems.

Unlike generic carbon cartridges, this filter has been independently tested and certified by IAPMO to NSF/ANSI 53 health-effects standards for PFAS reduction.

Key Benefits

• NSF / IAPMO Certified for PFAS Reduction
  Independently tested and certified to NSF/ANSI 53 for the reduction of PFOA and PFOS.

• Targeted PFAS Carbon Block Media
  Engineered specifically for adsorption of PFAS compounds, not just taste and odor.

• Cost-Effective PFAS Protection
  Lower ongoing replacement cost compared to proprietary PFAS systems.

• Standard Big Blue Size
  Fits most 4.5″ x 10″ Big Blue filter housings.

• High Flow for Point-of-Use Systems
  Certified flow rate supports kitchen and drinking water applications.

• Parallel Installation Capability
  Two cartridges may be installed in parallel to increase flow and service life.

• Simple DIY Replacement
  Drop-in cartridge design requires no special tools.

What This Filter Reduces

Certified reduction claims include:

• PFOA (Perfluorooctanoic Acid)

• PFOS (Perfluorooctane Sulfonate)

• Chlorine

• Taste and odor

• Sediment and particles down to 1 micron

IAPMO & NSF Certification (Important)

This filter is listed by IAPMO Research and Testing, Inc. as a Water Treatment Product – Health Effects, File No. W-12130. Certification includes:

• NSF/ANSI 53-2018 – Health effects standard

• Reduction claims:

  • PFOA / PFOS

  • Total PFAS (per NSF/ANSI 53, Section 7.2.6 protocol)

• Material safety and structural integrity verified

• Uniform Plumbing Code (UPC®) compliant

Products certified under this program are subject to ongoing surveillance, factory audits, and sample testing to ensure continued compliance. IAPMO R&T Product Listing

Certification demonstrates verified performance under standardized laboratory conditions. Actual results may vary based on water quality and usage.

Certified Performance (Model: FASBG01-B10)

• Nominal Micron Rating: 1 micron

• Certified Flow Rate:
  7 LPM (1.85 GPM)

• Certified Service Capacity:
  22,500 liters / 5,945 gallons
  – Based on NSF/IAPMO test protocols for PFAS and chlorine reduction

Recommended Applications

• Under-sink drinking water systems

• Dedicated kitchen drinking water faucets

• Small residential homes concerned about PFAS exposure

• Point-of-use PFAS reduction where whole-house systems are not required

Increasing Flow Rate (Parallel Configuration)

For higher demand or improved pressure performance, two identical cartridges can be installed in parallel:

• Increases total available flow

• Reduces pressure drop

• Extends effective service life per cartridge

This configuration is ideal for households that want higher flow without upgrading to larger or more expensive PFAS systems.

Technical Specifications

• Filter Type: Activated carbon block

• Dimensions: 4.5″ diameter × 10″ length

• Operating Pressure: 10–120 psi

• Operating Temperature: 40°F – 100°F

• Configuration: DOE / drop-in cartridge

• Manufacturer: Caware Filtering Corporation

• Country of Manufacture: Taiwan

Replacement Guidance

Filter life depends on:

• PFAS concentration

• Chlorine levels

• Daily water usage

• Flow rate

For best performance, replace the cartridge when rated capacity is reached or earlier if taste, odor, or flow noticeably changes.

Why We Carry This Filter

We selected this Caware PFAS carbon block because it combines:

• Verified NSF/IAPMO PFAS certification

• Realistic, defensible lifespan claims

• Standard sizing with no proprietary lock-in

• Competitive pricing versus resin-based PFAS filters

It delivers credible PFAS reduction without the complexity or cost of specialized systems.
