Why Activated Charcoal Filters Clog in the Cold — and What You Can Do About It

You’ve probably experienced this: You’re on the balcony, in the garden, or out for a walk and light up a joint. After a while, it gets harder to draw, and soon a brown, sticky goo starts oozing out of the filter. How does this happen?

Activated Charcoal Filters Clog — The Reason: Condensation

When you smoke a joint in the cold, the air condenses and forms tiny water droplets. These droplets mix with the accumulated toxins on the activated charcoal, creating that brown goo. Just a few drops are enough to clog both the activated charcoal and the holes at the filter’s end, restricting airflow.

How Can I Prevent Filters from Clogging?

With conventional activated charcoal filters, it’s hard to avoid this goo due to their design. Here’s what might help:

  • Avoid storing your filters in the cold.
  • Roll shorter joints.
  • Roll them looser.
  • Use unflavored tobacco!

Why Don’t Hybrid Filters Clog?

With our Hybrid Supreme Filter, the outer layer helps keep the cold from reaching the activated charcoal quickly. Additionally, most of the condensed moisture gets trapped in the cellulose, where it spreads out evenly and doesn’t reach the activated charcoal to form goo. While we can’t completely rule out clogging in very cold temperatures and with very long joints, Hybrid Supreme Filters generally keep you safe even in the cold.
