9. FAQ: Professional Q&A on Technical Terms

Frequently Asked Technical Questions
  • Q1: What is the difference between honeycomb and pleated carbon filters?
    A: Honeycomb filters embed carbon in hexagonal cells, offering high surface area and VOC removal; pleated types maximize dust/particulate holding via increased media area.
  • Q2: What materials are best for active carbon air filter for air purifier frames?
    A: Anodized aluminum (corrosion resistant), polypropylene (lightweight, high chemical tolerance), and custom-engineered plastics. Choice depends on use conditions and regulatory requirements.
  • Q3: Which standards apply for filter efficiency testing?
    A: EN 1822 (for HEPA/ULPA), ISO 10121 (for carbon adsorption), and ASHRAE 52.2/ISO 16890 (general HVAC use).
  • Q4: How often should activated carbon filters be replaced?
    A: Typically every 6–12 months, unless high VOC loads or specialized environments require shorter intervals (per ISO 16890 guidelines).
  • Q5: What is the pressure drop, and why is it important?
    A: Pressure drop (ΔP) is the resistance the filter adds to airflow; lower ΔP translates to energy savings and prolonged fan/lab equipment service.
  • Q6: Can filters be customized for non-standard shapes or machines?
    A: Yes—advanced production lines (e.g., with CNC/casting/molded process) enable tailored geometries, multi-layer fusion, OEM-printed logos/labels.
  • Q7: What is "service life," and how is it tested?
    A: Service life refers to the duration in which a filter maintains target efficiency; tested with accelerated gas/particle loading under standardized (ISO/ASTM) protocols.
