Polypropylene Electrostatic Screen
The polypropylene screen on AIRTEVA air filters plays a critical role in capturing airborne particles before they can circulate through your home. This durable, electrostatically charged material acts like a magnet for fine particulates such as dust, pollen, pet dander, and other allergens.
Unlike fiberglass or flimsy filter media, the woven polypropylene mesh provides a strong, consistent structure that traps contaminants effectively while allowing for optimal airflow. Its synthetic composition also resists moisture and microbial growth, making it a cleaner, longer-lasting solution for improving indoor air quality.
Polypropylene fibers used in Airteva air filters can hold an electrostatic charge, allowing them to attract and capture airborne particles like a magnet. This electrostatic effect plays a crucial role in air filtration, enhancing the filter’s ability to trap fine dust, pollen, and other microscopic pollutants.
Here's how it works:
Generating the Electrostatic Charge:Triboelectric Charging: Polypropylene, being a synthetic polymer, tends to become electrostatically charged when it comes into contact and then separates from other materials. This is known as the triboelectric effect. Electrons are transferred between the surfaces, leaving one surface with a net positive charge and the other with a net negative charge.
How the Electrostatic Charge Captures Particles:
Electrostatic Attraction: Once the polypropylene fibers have an electrostatic charge, they create an electric field around them. When airborne particles (such as dust, pollen, pet dander, bacteria, and some viruses) pass through this field, they can become polarized or even charged themselves through induction or contact charging.
Coulombic Force: The charged fibers then exert an attractive force (Coulombic force) on these particles, pulling them towards the fiber surface and causing them to stick. This is similar to how a statically charged balloon can stick to a wall.
