Bipolar ionization devices effectively reduce TVOCs by oxidizing them into harmless compounds and aiding their removal.
(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 pollutants, including TVOCs.
(2) Chemical Breakdown of TVOCs
- TVOCs are organic chemicals (e.g., benzene, formaldehyde, toluene) that easily evaporate at room temperature.
- When bipolar ions encounter TVOC molecules, they:
- Oxidize them by breaking carbon-hydrogen (C-H) and carbon-carbon (C-C) bonds.
- Convert complex VOCs into simpler, less harmful compounds like CO₂ (carbon dioxide) and H₂O (water vapor).
(3) Secondary Reaction with Hydroxyl Radicals (·OH)
- BPI can generate hydroxyl radicals (·OH), highly reactive oxidizers that further break down VOCs.
- These radicals react with TVOCs in a process similar to natural outdoor air purification (like sunlight-driven atmospheric cleaning).
(4) Effectiveness of BPI in Handle TVOCs
- Studies show BPI can reduce certain VOCs by 30–90%, depending on:
- Ion concentration
- Airflow rates
- VOC type (some are harder to break down than others)
- Humidity and temperature
