What’s really going on inside those carbon filters we see in fridges, faucets, and whole-house systems? In this episode of The Toxic Truth About Water, Drs. Glenn and Ina break down how carbon filtration actually works (adsorption vs. absorption) and the different types of carbon—granular, block, catalytic—that can make a difference in your water quality. Learn which contaminants it’s good at removing, what it can’t handle, and why maintenance matters more than you think.

What You’ll Learn

• Carbon Filter Basics: The science behind adsorption and why carbon has limits.
• Types of Carbon Media: Granular, block, catalytic, and coconut-based—plus why they’re not all created equal.
• Pros & Cons: How carbon filtration improves taste and odor but may fail against bacteria, mold, or biofouling.
• Why Maintenance Is Key: Changing your carbon filter on time is critical to avoid contaminant “overflow.”

Key Takeaways

1. Not a Silver Bullet: Carbon filters excel at removing chlorine and some chemicals but won’t handle all toxins—especially biological ones.
2. Different Forms, Different Results: Block vs. granular carbon yields varying degrees of filtration and water flow.
3. Frequent Replacement: Once carbon is “full,” it can release contaminants back into your water.
4. Layered Approach: Carbon is often just one step—like in reverse osmosis systems—to tackle a broader range of contaminants.
