CBC-20, Pentek 20" Micro Carbon Block, 155309-43

High-Performance Micro Carbon Block Filter Cartridge for Cleaner, Fresher Water

The CBC-20 Pentek 20" Micro Carbon Block, model 155309-43, is designed to deliver superior filtration performance in residential and commercial water systems. Unlike generic filters, this micro carbon block cartridge efficiently reduces chlorine, taste, odor, and other contaminants, ensuring safer and better-tasting water. As a trusted filter cartridge solution, it offers reliable protection and improved water quality for any setup needing effective carbon filtration.

Key Benefits

• Improves water taste and odor by effectively reducing chlorine and organic chemicals
• Protects downstream equipment by trapping sediment and particulate matter
• Enhances water clarity through fine micro carbon block filtration
• Compatible with a wide range of standard 20" housings for easy installation
• Durable construction ensures consistent performance over its lifespan
• Supports healthier water by minimizing common contaminants linked to unpleasant water quality

How It Works

The CBC-20 utilizes a dense micro carbon block that acts as a physical barrier and adsorbent surface. As water passes through the cartridge, impurities such as chlorine, volatile organic compounds (VOCs), and certain chemicals adhere to the carbon’s porous structure. Simultaneously, the carbon block filters out fine particles and sediment, improving overall water clarity and taste.

This cartridge is typically installed in-line within a water filtration system, where it serves as a key stage in reducing unwanted contaminants before water reaches taps or appliances. Its 20-inch length provides ample surface area for effective filtration without compromising flow rate.

What to Expect

Immediately after installation, you’ll notice a reduction in chlorine taste and odor, resulting in fresher, cleaner water. Over the first few days and weeks, the filter continues to adsorb organic compounds and particulates, steadily improving water quality.

With proper maintenance and timely replacement, the CBC-20 maintains reliable filtration performance. Regular cartridge changes help preserve system efficiency and prevent clogging, ensuring long-term benefits and consistent water purity.

What’s Inside

• Micro Carbon Block Core – Provides high adsorption capacity to remove chlorine, VOCs, and other contaminants
• Polypropylene Outer Shell – Durable housing that protects the carbon block and maintains structural integrity
• Sealing End Caps – Ensures leak-free installation and proper water flow direction
• Fine Porosity Structure – Enhances sediment filtration without significantly reducing flow rate

How to Use

1. Turn off the water supply before beginning filter replacement.
2. Release pressure by opening a nearby faucet or using a pressure release button if available.
3. Unscrew the existing filter housing using a filter wrench if necessary.
4. Remove the old cartridge and properly dispose of it.
