KX Technologies - FXHTC11CL2 - Filtrex Ecocarb GreenBlock CL2 - 10 Mircon Carbon Block Hydrotech/Clack Compatible Filter
Hydrotech/Clack Compatible FXHTC11CL2 EcoCarb GreenBlock 10 Micron Carbon Block Filter
High-performance coconut shell carbon block prefilter engineered for Hydrotech and Clack RO systems. Eco-friendly manufacturing with superior chlorine reduction and sediment filtration down to 10 microns.
Coconut shell carbon with lower emissions and higher capacity
Coconut Shell Activated Carbon
More micropores than standard carbon types provide greater surface area for contaminant adsorption. Unique binder system prevents carbon fines from releasing during filtration.
GreenBlock Manufacturing
Part of the CL2 Series, manufactured using a process that significantly reduces greenhouse gas emissions compared to conventional carbon block production methods.
10 Micron Filtration
Reduces chlorine taste and odor while capturing dirt, sediment, rust, sand, silt, and other particulates down to 10 microns. Protects RO membranes from premature fouling.
Low Pressure Drop Design
High dirt holding capacity with only 1.6 PSI pressure drop at rated flow. Maintains consistent flow throughout the filter life without starving your RO system.
FXHTC11CL2 Technical Details
| Dimensions | 11.75" L × 1.9" W (11.6" nominal) |
| Micron Rating | 10 micron nominal |
| Filter Media | Coconut shell carbon block |
| Flow Rate | ~1 GPM @ 1.6 PSI |
| Temperature Range | 40°F – 180°F |

| Service Life | 3–6 months (usage dependent) |
| Certifications | NSF 42 Material Safety, NSF 61 Carbon, WQA Gold Seal |
Designed for Hydrotech and Clack RO Systems
The FXHTC11CL2 replaces carbon prefilters in any Hydrotech or Clack reverse osmosis system that accepts 11.6" length × 2" diameter carbon block cartridges. This filter is a direct fit for the standard prefilter housing on these platforms. Verify your existing filter dimensions before ordering: if your current cartridge measures approximately 11.75" long and 1.9" wide, this is the correct replacement. Also compatible with many whole-house systems and other RO brands that use this cartridge size.
Replacement Schedule
High Chlorine or Heavy Use
Municipal water with heavy chlorine treatment or households using more than 50 gallons per day through the RO system. Replace sooner if you notice flow rate decline or taste changes.
Standard Residential Use
Typical replacement interval for most households. Change the FXHTC11CL2 at six months even if flow seems adequate to maintain chlorine reduction and protect your membrane.
Monitor Performance
Replace earlier if you detect chlorine taste or odor in filtered water, notice significant flow reduction, or if sediment levels in your source water are unusually high.
Drop-In Replacement
Standard cartridge design fits existing Hydrotech and Clack housings without modification
Membrane Protection
Removes chlorine and sediment that degrade expensive RO membranes and reduce system life
Eco-Conscious Choice
GreenBlock CL2 manufacturing process reduces carbon footprint without sacrificing filtration performance
Third-Party Verified
NSF 42 and NSF 61 certifications plus WQA Gold Seal listing confirm material safety and quality
