Air Filter Cotton‌

Air filter cotton is a material used to filter dust particles in the air, widely applied in air purification for households, industries, and specialized environments (such as paint booths, HVAC systems, etc.). Depending on material and filtration efficiency, it can be categorized into the following types:

‌Main Types & Features‌

1. ‌By Material‌

   • ‌Synthetic Fiber Filter Cotton‌: Gradually increasing density, low initial resistance, high dust holding capacity, and reusable after cleaning.
   • ‌Non-Woven Filter Cotton‌: Durable structure with good breathability, commonly used for dust and lint interception in air intake vents.
   • ‌Fiberglass Filter Cotton‌: Heat-resistant, suitable for high-temperature industrial exhaust treatment.
   • ‌Activated Carbon Filter Cotton‌: Integrated adsorption function, capable of removing harmful gases like formaldehyde.

2. ‌By Filtration Efficiency‌

   • ‌Primary Filter Cotton (G1-G4)‌: Filters particles ≥5μm, used for pre-filtration in ventilation systems.
   • ‌Medium-Efficiency Filter Cotton (F5-F8)‌: Filters particles ≥1μm, suitable for secondary filtration.

‌Core Functions & Applications‌

• ‌Household use‌: Installed in air conditioner intakes to reduce indoor dust and pet hair, extending equipment lifespan.
• ‌Industrial use‌: Applied in paint booths and electronics manufacturing for clean air environments, reducing product defect rates.
• ‌Specialized needs‌: Medical-grade filter cotton for respirators requires high adsorption rates.
