Pentek TSGAC-10 10" Granular Activated Carbon + Phosphate Cartridge – Chlorine, Taste & Scale Protection | Osmotics UK

Protect your appliances, fixtures, and water quality with the Pentek TSGAC-10—a premium 10-inch specialty cartridge combining granular activated carbon (GAC) for superior taste, odour, and chlorine reduction with phosphate crystals for effective scale and rust stain prevention. This dual-action filter is ideal for homes or businesses dealing with hard UK water, chlorinated supplies, or equipment prone to limescale buildup (e.g., coffee machines, kettles, boilers, washing machines, or RO system post-treatment).

The high-surface-area GAC granules adsorb chlorine, chloramine, VOCs, pesticides, and organic chemicals that cause bad tastes/odours, while the slow-release phosphate sequesters calcium/magnesium to inhibit scale deposits and reduce rusty staining—providing comprehensive protection without harsh chemicals.

Key Benefits

• Crystal-clear taste & no chlorine aftertaste — Removes unwanted flavours/odours for better drinking/cooking water.
• Scale & rust prevention — Phosphate crystals reduce limescale buildup and iron-related stains on fixtures/appliances.
• Appliance & plumbing longevity — Lowers maintenance costs by protecting water lines, heaters, and major equipment.
• Low pressure drop — Maintains good flow rates even in standard housings.
• Versatile & reliable — NSF/ANSI Standard 42 certified for material safety; excellent for hard-water areas.
