Features: 
• Less dense filters make the difference: Our unique HEPASilent™ filtration technology allows our filters to be less dense. Less dense filters require less air pressure— resulting in quieter and more energy efficient air purifiers. 
• Protection against particles: In addition to removing gases and odors, DualProtection filters are highly efficient in eliminating airborne particle pollutants from your home, including allergens, pollen, dust, mold, pet dander, viruses, and fine smoke particles. 
• Traps particles for good: The filter structure traps even the smallest particles and resists clogging to maintain maximum airflow. 
• Recyclable: This filter is recyclable, so the only thing you're adding back into the environment is clean air. Please check your local recycling facilities for availability. 
• No chemical additives: Free of chemical additives, this filter uses pure, high-porosity coconut carbon to remove odors. Filter fibers resist bacteria and mold growth. 
• 6-month filter life: To maintain optimum performance, we recommend changing your filter about once every 6-months when used 24 hours a day.
