Cardboard Synthetic Prefilter Role in Air Filtration Systems

As the first line of defense cardboard synthetic prefilters trap larger particles, such as dust, pollen, and pet dander, preventing them from entering the main filter. This not only ensures better air quality but also extends the lifespan of the more expensive main filters.


How Cardboard Synthetic Prefilters Work

Particle Capture Mechanism

Cardboard synthetic prefilters use a combination of mechanical and electrostatic filtration to capture larger particles. The fibers in the filter create a maze-like path that causes particles to get trapped, while electrostatic charges attract and hold particles with a positive charge.


Increased Surface Area

Cardboard synthetic prefilters are pleated or folded to increase their surface area. This design feature allows for better particle capture and ensures a longer service life for the filter.


Advantages of Cardboard Synthetic Prefilters

Enhanced Air Filtration Efficiency

By capturing larger particles, cardboard synthetic prefilters prevent them from reaching the main filter, leading to better air quality and improved overall filtration efficiency.


Extended Lifespan of Main Filters

With the larger particles filtered out by the cardboard synthetic prefilter, the main filters experience less clogging, reducing the frequency of filter replacements and maintenance.


Cost-Effectiveness

Cardboard synthetic prefilters are relatively inexpensive compared to main filters. Their use results in cost savings by prolonging the life of more expensive filters.
