The AC Infinity Pre-Filter Cloth for Inline Carbon Filter, 4-Inch, 2-Pack, is designed to enhance the performance and longevity of your carbon filter system. These pre-filters serve as the first line of defense, protecting the charcoal bed from debris and ensuring optimal air filtration and odor control.
Key Features:
- Enhanced Protection: Each pre-filter is crafted from high-quality polyester, effectively blocking larger particles such as dust, lint, pollen, and hair. This protective barrier prevents clogging of the charcoal bed, ensuring that your carbon filter continues to operate at peak efficiency.
- Breathable and Efficient: The breathable fabric of the pre-filter allows for complete air passthrough, maintaining proper airflow and filtration without restricting performance. This ensures that odors are effectively trapped in the activated charcoal while allowing for smooth air circulation.
- Durable and Reusable: These pre-filters are designed for long-lasting use, capable of being reused for up to six months. Regular maintenance is simple: just vacuum the pre-filter to remove accumulated dust before machine washing. Hang drying is recommended to prevent shrinking and maintain the form-fitting design.
- Easy Installation: The pre-cut design of these pre-filters ensures a snug fit on 4-inch carbon filters, making installation quick and hassle-free. They can be slipped onto the exterior for intake airflow applications or placed in the inner chamber for exhaust configurations.
