- ACTIVATED CARBON AIR FILTER: Breathe Naturally's activated carbon air filter uses advanced activated carbon to capture and neutralize smoke, household odors, and airborne pollutants. This technology effectively neutralizes harmful particles and contaminants, enhancing indoor air quality. By providing an additional layer of filtration, the pre-filter helps maintain a fresher atmosphere and improves overall air quality.
- EXTRA THICK FILTRATION: Our activated carbon air filters are 0.2 inches thick, offering greater filtration capacity than standard 0.1-inch carbon filters. This extra thickness allows them to combat pet hair, pollen, smoke, dust and more, without restricting airflow. Designed for efficiency, these activated carbon air filters improve air quality by capturing a wider range of pollutants while maintaining optimal airflow. Perfect for homes or offices.
- UNIVERSAL CUT TO FIT: Each activated carbon air filter comes with two hook & loop tapes for easy attachment & can be adjusted to fit a wide range of applications. Simply cut the activated carbon air filter to the required size for a perfect fit. These versatile carbon filters are ideal for use in air purifiers, vents, fans, windows, trash cans, litter boxes, range hoods, furnaces, HVAC systems, dehumidifiers, & many other uses. This customizable design ensures no gaps for unfiltered air.
- MULTIPLE SIZE AND PACK: These activated carbon air filters are available in various sizes & come in packs of 1, 2, 4, or 6 to suit your needs. Whether you require a single carbon filter or multiple replacements, these options offer convenience and value. Designed to fit your specific requirements, they help you maintain optimal air quality in your home by ensuring regular activated carbon air filter replacements. Choose the pack size that most suits your needs and enjoy fresher air with ease.
