Key Benefits

• Enhances water taste and odor by removing chlorine and organic compounds
• Protects plumbing and appliances from sediment buildup and contaminants
• Extends the lifespan of your water softener and filtration system
• Delivers consistent filtration performance with a durable 5-micron rating
• Easy to install and replace, minimizing maintenance downtime
• Compact 4.5" x 20" size fits standard housings for versatile use

How It Works

This carbon block filter cartridge uses a dense, compressed carbon medium to physically trap sediments and chemically adsorb chlorine and other impurities from water. As water flows through the cartridge, contaminants are captured within the porous carbon matrix, improving water clarity and taste. It acts as a critical pre-filter or polishing stage in your water treatment setup, ensuring downstream components receive cleaner water and operate more efficiently.

The 5-micron filtration rating balances effective contaminant removal with optimal flow rate, making it ideal for home water softeners, reverse osmosis systems, and whole-house filtration units.

What to Expect

Immediately after installation, you’ll notice a reduction in chlorine smell and improved water taste. During the first few weeks, the cartridge will efficiently trap sediment and other particles, helping to protect your plumbing fixtures and appliances. Over time, the filter maintains consistent performance thanks to its robust carbon block construction, though periodic replacement is needed to ensure ongoing effectiveness.

Regular monitoring of water flow and taste will help you determine when it’s time to change the cartridge, typically every 6 to 12 months depending on water quality and usage.

What’s Inside

• Activated Carbon Block – Provides high surface area for adsorption of chlorine, chemicals, and odors
• Polypropylene Core – Ensures structural integrity and prevents carbon dust from entering your water supply
• Durable Outer Wrap – Protects the carbon block and maintains consistent filtration performance
• Standard 4.5" x 20" Dimensions – Compatible with most 20-inch filter housings for easy integration

How to Use

1. Turn off the water supply to your filtration system before beginning installation.
2. Release pressure by opening a faucet or using the pressure relief valve on the filter housing.
