How bipolar ionization helps on reduces PM (particulate matters)?

Bipolar ionization is an air purification technology that can help reduce particulate matter (PM) in indoor environments. It helps reduce PM by enlarging particles for easier filtration and causing them to settle faster. Here’s how it works and its impact on PM:

(1)Generation of Ions  

  • Monitair’s bipolar ionization devices produce both positive and negative ions (O₂⁺ and O₂⁻) using high-voltage electrodes.
  • These ions disperse into the air and interact with airborne particles, gases, and microorganisms.

(2) Agglomeration (Clustering) of Particles

  • The ions attach to PM (PM₁₀, PM₂.₅, and even ultrafine particles).
  • This gives the particles an electrostatic charge, causing them to cluster together (agglomerate).
  • Larger clusters are easier to capture via:
    • Air filters (since bigger particles get trapped more efficiently).
    • Gravity (heavier particles settle faster).

(3)  Enhanced Filtration Efficiency

  • Standard HVAC filters may miss very small particles.
  • Bipolar ionization makes particles larger, improving filter capture rates without requiring HEPA filters. 

(4) Neutralization of Airborne Particles

  • Some charged particles become attracted to surfaces (walls, floors) instead of staying suspended.
  • This reduces PM concentration in breathing zones. This reduces PM concentration in breathing zones.

(5) Applications

  • HVAC systems (commercial buildings, hospitals, schools).
  • Industrial settings (reducing dust and smoke).
  • Public transport (airplanes, buses) to improve air quality.
