Flat Antibacterial HEPA Filter

This is a flat antibacterial HEPA filter from Oltaven that combines high-efficiency particulate arrestance with an antimicrobial and antiviral coating. It captures PM2.5, pollen, pet dander, cigarette smoke, and microbial aerosols while inhibiting influenza A virus, E. coli, and Staphylococcus aureus. It is designed for air purifiers, vehicle purifiers, fresh-air air conditioners, medical disinfection equipment, and maternal-infant health appliances.

From Media to Finished Filter

Our filter media is a multi-layer composite with a high-density pleated structure, yet the finished filter’s performance is determined not just by the media but by how it is pleated, framed, and sealed. The pleating process sets the surface area and the gap between pleats; the frame provides rigidity and dimensional stability; the sealant ensures that air cannot bypass the filter. At Oltaven, we sell finished filters, not just media, so every step from slitting to packaging is controlled in-house.

What Decides Finished Performance

Three factors govern the final efficiency, resistance, and dust-holding capacity. First, media choice: the base HEPA layer determines particle capture, while the antibacterial and antiviral coating adds microbial control. Second, pleat geometry: more pleats increase surface area and lower initial resistance, but too many pleats can reduce dust-holding capacity. Third, framing and sealing: a rigid frame maintains pleat spacing, and a continuous seal prevents leakage. Our flat design is ultra-thin, allowing flexible integration into compact devices without sacrificing performance.

Applications

This filter is used in household air purifiers, vehicle purifiers, fresh-air air conditioning systems, medical disinfection equipment, and maternal-infant health appliances. The antibacterial and antiviral properties make it suitable for environments where microbial control is important, such as homes, offices, and healthcare settings. For mite-sensitive users, the filter achieves a mite removal rate of up to 82.4% (tested according to FZ/T01100-2008 by a national authoritative institution).

OEM/ODM Workflow

1. Inquiry: share your device model, required dimensions or drawing, airflow, operating conditions, and estimated quantity.
2. Proposal: we recommend media grade, pleat configuration, frame, and sealing based on your specifications.
3. Sampling: custom samples typically in 7–15 working days (standard samples 3–5 days).
4. Validation: you test samples in your device; we adjust as needed.
5. Production: after approval, we manufacture with IQC, IPQC, and OQC throughout.
6. Delivery: standard lead time 25–35 days for regular orders.
