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.
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.
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.
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).

Oltaven has over 20 years of experience in filter R&D and manufacturing, with more than 1,000 filter solutions developed for customers worldwide. Our 50,000 m² plant in Zhongshan, Guangdong, China, includes six cleanrooms totaling 20,000 m², where HEPA filters are produced under controlled conditions. Our in-house CNAS-accredited laboratory can issue test reports for filtration efficiency, dust-holding capacity, and resistance. We are certified to IATF 16949 (2024) and ISO 9001, ISO 14001, and ISO 45001, and our products comply with REACH and RoHS regulations. With multiple automated production lines, we can deliver millions of filters per month.
To receive a tailored quote, please provide your device or vehicle model, required size or drawing, airflow or water flow (if applicable), operating conditions, and estimated quantity. Contact Oltaven to discuss your project.
Resistance depends on pleat count, media permeability, and the seal between the filter and its frame. More pleats increase surface area and lower resistance, but excessively tight pleating can reduce dust-holding capacity. Oltaven balances these factors for each custom design.
It starts with your specifications: device model, dimensions or drawing, airflow, operating conditions, and quantity. We then propose a filter design, provide samples for validation (custom samples usually in 7–15 working days), and proceed to production after approval.
The filter is available in H11 to H14 grades, with efficiency up to 99.995% for 0.3 μm particles. All performance data are tested in our CNAS-accredited laboratory according to EN 1822 and GB/T 13554 standards.
Yes. We support full OEM/ODM customisation, including dimensions, thickness, filtration grade, frame material, media combination (HEPA + activated carbon + antibacterial layer), pleat count, sealant process, and packaging. Our team can quickly develop samples based on your device model.
Standard samples are available in 3–5 working days; custom samples typically take 7–15 working days. Sample costs are refundable against bulk orders. Quotes are provided after we receive your specifications.
For standard specifications, MOQ is usually 500–1,000 pieces; for custom specifications, MOQ is generally 2,000–3,000 pieces depending on materials and structure. Standard lead time is 25–35 days after order confirmation.
Replacement intervals depend on operating conditions and dust loading. We recommend monitoring pressure drop or following your device manufacturer’s schedule. For assistance, contact our technical team.
Every batch undergoes IQC, IPQC, and OQC checks, including efficiency, resistance, and scan leak tests in our CNAS laboratory. Our cleanroom production and IATF 16949 system ensure automotive-grade consistency. For a custom filter solution, <a href="/en/contact">contact us</a> today.
