High-capacity Big Blue coconut carbon block that reduces chlorine, bad taste, and odor at whole-house flow rates — the polishing carbon stage that makes water from every tap taste better.

What it does

The CTO (Chlorine, Taste & Odor) carbon block is the carbon polishing stage of a whole-house system. Water passes through a solid block of compressed coconut-shell activated carbon, which adsorbs chlorine and the compounds behind bad taste and odor — so the improvement reaches every tap, shower, and appliance in the house.

Carbon block beats loose carbon for fine filtration. Because the media is a sintered solid block rather than loose granules, water can’t channel around it — every gallon gets full contact with the carbon. The 10-micron nominal structure also captures fine particles that pass a coarser sediment stage, improving water clarity along with taste.

The 10″ × 4.5″ Big Blue format carries several times the carbon of a slim 10″ × 2.5″ cartridge, which is what makes carbon treatment practical at whole-house flow: more contact area, longer life, and less pressure drop. It also protects plumbing and any downstream filters from carbon fines and residual particulate.

Key benefits

• ✓ Reduces chlorine, bad taste & odor house-wide
• ✓ Solid coconut carbon block — no channeling, full carbon contact
• ✓ 10-micron fine filtration improves water clarity
• ✓ Big Blue capacity — high flow, long life, low pressure drop
• ✓ Protects plumbing & downstream filters
• ✓ Better-tasting water at every tap — not just the kitchen
