A carbon block filter is a highly effective type of activated carbon filter used to remove chlorine, chemicals, taste, odor, and some contaminants from water. It’s denser and more efficient than granular carbon (GAC) filters.
Material: High-quality activated carbon (often coconut shell-based)
Micron Ratings: Typically 0.5 – 10 microns
0.5–1 micron: Removes finer particles and some cysts (like Giardia, Cryptosporidium)
5–10 micron: More general use (better flow rate)
Removes: Chlorine, taste, odor, VOCs, THMs, and some heavy metals
Used In: Under-sink systems, RO systems, countertop filters, whole-house systems
Low pressure drop: Maintains efficient flow due to uniform pore distribution
Flow Rate: Slower than GAC filters but more effective
Filtration Type: Adsorption + mechanical filtration
Better Than GAC: Tighter structure = less channeling, better contaminant removal
Excellent chlorine and taste/odor removal
Longer contact time = better filtration
Less risk of “channeling” compared to GAC filters
Can filter out sediment and some microorganisms
Often NSF-certified for safety and performance
Filtration Type: Depth filtration via melt-blown PP fibers.
Efficiency: Excellent—captures very fine particles (down to 0.1–1 µm).
Dirt Capacity: High, thanks to gradient layering.
Durability & Safety: Robust chemical resistance; no binders; FDA-compliant.
Performance: Efficient flow (low pressure drop); suitable across varied industries.
Variations: Available in flat, grooved, embossed forms to optimize performance.
Ideal For: Pre-filtration in water systems, industrial filtration, and sensitive applications.
