Clean the Air You Breathe
3M® Carbon Web Technology combines activated carbon with electrostatically charged fibers. The activated carbon is made up of many tiny pores. As air passes through the filter, odors and gases become trapped in the pores. This helps reduce odors in your home caused by: pets, tobacco smoke, cooking, mildew, and cleaning chemicals.
The Filtrete™ carbon filter is the best at removing odors and airborne particles while maintaining airflow.
*The Filtrete™ carbon filter is significantly more effective at removing odors than other carbon filters based on a comparison of organic vapor capacity vs. other national retail HVAC filter brands.
