High Dust Holding Capacity Primary Intake Filter Media for Air Filter Practical Air Inlet Pre Filter Rolls for HEPA Filtration System

Pre-filters are crucial for the performance of air purification systems as they are responsible for trapping larger particles like dust, pet dander, and hair. These filters act as the primary defense by capturing these particles before the air undergoes further filtration stages, enhancing the overall efficiency and effectiveness of the system.
1. High Particle Capture Efficiency: Effectively traps larger airborne particles such as dust, pollen, lint, and hair, protecting your main filter and enhancing overall air quality.
2. Optimized Airflow: Engineered to allow maximum airflow while maintaining high filtration efficiency, reducing pressure drop and ensuring the smooth operation of your HVAC system.

Pre-filters are the initial line of defense in an air purification system. They are the first stage of filtration, designed to capture larger particles and prevent them from entering the main filtration system. These particles can include dust, hair, pet dander, pollen, and other visible debris commonly found in indoor environments. It can effectively filter harmful substances in the air to ensure your health. We pay attention to every detail, carefully designing and manufacturing the filter wool to ensure that it is tightly structured, not easy to deform, and provides stable and reliable filtration effect.Filter cotton is suitable for home, office, car and other occasions, can effectively purify the air, let you breathe fresh and healthy air environment.

Our filter cotton adopts simple design, which is easy and quick to install, and also very simple to clean, only need to gently tap or rinse with water to restore the filtration effect, saving time and labor.

FEATURES

● Made from organic synthetic fiber, it offers excellent resistance to creasing, as well as superior elasticity and stability

● Featuring an incremental structure with multi-layer step-by-step encryption technology, it can trap dust at different density levels based on particle size, enhancing its dust-holding capacity

● The air outlet surface is reinforced with a net, and an additional layer of square woven net (with optional net or cloth surface) is added for extra strength and shape retention

● High dust-holding capacity, low resistance, and cost-effective practicality

● The filter material undergoes full gum dipping treatment to prevent fiber shedding; it can be fully adhesive, surface adhesive, or processed dry

● 380g/400g/500g/600g available 

● Washable economical
