Importance in Air Filtration Systems

As the first line of defense cardboard polycotton prefilters remove larger particles, such as dust, pet dander, and pollen, from the air stream. By doing so, they protect the main filters from premature clogging and optimize the overall air filtration efficiency.


How Cardboard Polycotton Prefilters Work

Dual Filtration Mechanism

Cardboard polycotton prefilters utilize a dual filtration mechanism. The cardboard frame provides structural support, while the polycotton fibers create a dense filtering media that effectively traps larger particles.


Particle Capture Efficiency

The combination of cardboard and polycotton fibers results in a higher particle capture efficiency compared to standard cardboard or synthetic prefilters. The polycotton fibers have excellent dust-holding capacity, ensuring superior filtration performance.


Advantages of Cardboard Polycotton Prefilters

Superior Filtration Performance

Cardboard polycotton prefilters offer better particle capture efficiency, leading to improved indoor air quality and healthier environments.


Extended Lifespan of Main Filters

By capturing larger particles, these prefilters prevent them from reaching the main filters, reducing the frequency of filter replacements and maintenance.


Cost-Effectiveness and Sustainability

Cardboard polycotton prefilters are cost-effective solutions that contribute to sustainability due to their longer service life and eco-friendly materials.
