Activated Carbon Filter
Activated charcoal filters absorb odor molecules and other pollutants in the air. They require three things to work properly.
1. Humidity must be below 55 percent. Above 65-70 percent relative humidity, the charcoal absorbs so much moisture that it clogs.
2. Air must move slowly through charcoal filters to extract odors.
3. Use a pre-filter to remove dust, and change it every 60 days.
Do not use activated carbon that is “crushed”. It is less efficient than charcoal pellets.
