20″ Big Blue 5 Micron Carbon Block

Description

The 20″ Big Blue 5 Micron Carbon Block Filter is a high-capacity drinking water filter cartridge designed for whole-house and point-of-entry (POE) filtration systems. Engineered with activated carbon block media, this large-format filter reduces chlorine, taste, odor, and many chemical contaminants while also trapping fine sediment down to 5 microns nominal — delivering cleaner, better-tasting water for your home, cottage, or commercial installation.

Key Features

• 5 Micron Nominal Rating — Effectively captures fine particles like sediment, rust, and silt while reducing chlorine taste and odor.
• Activated Carbon Block Media — High surface area carbon delivers excellent adsorption of chlorine, chemical compounds, and volatile organic compounds (VOCs).
• Big Blue Format (20″ × ~4.5″) — Larger media volume for greater contaminant load and longer service life compared with smaller cartridges.
• Universal Fit — Fits most 20″ Big Blue housings (4.5″ diameter) used in residential and light commercial water filtration applications.
• Improved Water Taste & Clarity — Great for enhancing drinking water quality throughout the home.

Specifications

• Size: ~20″ Length × ~4.5″ Diameter (Big Blue)
• Micron Rating: 5 micron (nominal)
• Media: Activated carbon block
• Material: Extruded or compressed carbon with molded end caps
• Operating Temperature: Typically ~40 °F – 125 °F (4 °C – 52 °C)
• Application: POE and whole-house water filtration systems (carbon + particulate)

Compatibility

• Fits standard 20″ Big Blue housings from major brands — ideal for high-flow point-of-entry filtration.
• Designed to work as part of multi-stage filter systems (e.g., paired with sediment pre-filters and post-polishing filters).

Applications

• Whole-House Filtration — Improves water taste, odor, and clarity for all fixtures.
• Pre-Treatment for Sensitive Systems — Protects downstream equipment like water softeners, RO systems, and UV disinfection units.
• Commercial & Residential POE — Effective in residential homes, cottages, offices, and light commercial setups.

Maintenance & Replacement

• Recommended Replacement: Approximately every 6–12 months, depending on water quality and usage.
• Monitor water clarity and taste; replace sooner if flow decreases or water quality declines.
• Flush the filter after initial installation to remove loose carbon fines (common with carbon blocks).

Why Choose a Big Blue 5 Micron Carbon Block Filter?

A 20″ Big Blue 5 Micron Carbon Block Filter offers an excellent balance of sediment capture and chemical removal for whole-house water treatment. Its larger media volume supports higher flow rates with longer service life, making it a dependable solution for improving drinking water quality and protecting your plumbing and water-using appliances.
