This is a cylindrical HEPA filter with an antibacterial and antiviral coating, designed to capture PM2.5, pollen, pet dander, smoke particles, and dust aerosols while inhibiting influenza A virus, E. coli, and Staphylococcus aureus. It is available as a finished filter from Oltaven, a manufacturer with over 20 years of filtration experience. The 360° pleated design maximises airflow and CADR, making it suitable for high-end car air purifiers, compact home or desktop purifiers, and maternal-infant health appliances.
Media selection is only the starting point. The finished filter’s efficiency, resistance, and dust-holding capacity are determined by how that media is pleated, framed, and sealed. A high-efficiency media can lose performance if pleats are too tight or the frame allows air to bypass. Conversely, careful forming can enhance media performance and extend service life.
At Oltaven, we sell finished filters, not just media. Our engineers consider the entire construction—pleat geometry, frame rigidity, seal integrity, and coating uniformity—to deliver a filter that meets your device’s airflow and efficiency targets. This principle-driven approach ensures that every cylindrical filter we produce performs as specified in real-world applications.
Three factors primarily govern the performance of a finished cylindrical filter: pleat design, frame and seal integrity, and the uniformity of the antibacterial/antiviral coating.
Pleat design: The number and height of pleats affect the filter’s surface area, which in turn influences efficiency, resistance, and capacity. More pleats increase surface area, lowering resistance and raising dust-holding capacity, but if pleats are too dense, airflow can be restricted and pleats may collapse under pressure. Our 360° high-density pleating balances these factors to maximise CADR while maintaining low resistance.
Frame and seal integrity: The frame provides structural support and prevents air bypass. A rigid frame maintains pleat spacing and protects the media during handling and installation. Sealing ensures that all air passes through the media, not around it. We use automated processes to apply consistent adhesive seals that withstand operating pressures and temperature variations.
Coating uniformity: The antibacterial and antiviral coating must be applied evenly across the media to ensure consistent inactivation of microorganisms. Our coating processes—such as silver-ion loading and copper-zinc composite treatments—are carefully controlled to achieve uniform distribution without blocking airflow. This is validated through testing in our CNAS-accredited laboratory.
Together, these forming decisions determine the finished filter’s efficiency (e.g., PM2.5 filtration), resistance (pressure drop), and capacity (dust holding). By controlling each step, we deliver filters that meet specified performance and reliability standards.
The cylindrical antibacterial and antiviral filter is designed for applications where space is limited but high airflow and efficiency are required. Typical uses include:
With a mite removal rate of up to 82.4% (tested according to FZ/T01100-2008 by a national authority), this filter also supports allergy-sensitive environments.

Resistance is influenced by pleat density, media permeability, and frame design. Even with identical outer dimensions, a filter with more pleats and a more open media can have lower resistance than one with fewer pleats or tighter media. Our cylindrical filter uses a 360° high-density pleat pattern optimised for low resistance and high airflow.
An OEM project begins with your inquiry, including device model, dimensions or drawing, airflow, operating conditions, and quantity. We then design a solution, provide samples for validation, and proceed to mass production after approval. The typical sampling time is 7–15 working days.
The cylindrical filter effectively captures PM2.5, pollen, pet dander, and dust aerosols. It inhibits influenza A virus, E. coli, and Staphylococcus aureus, with a mite removal rate of up to 82.4% according to FZ/T01100-2008. Test reports from our CNAS-accredited laboratory are available upon request.
Yes, we fully support OEM/ODM customisation. You can specify outer diameter, inner diameter, height, pleat count, and filtration efficiency. We also offer tooling and contract manufacturing for custom dimensions.
We provide samples for evaluation. Standard samples ship within 3–5 working days; custom samples typically take 7–15 working days. Sample costs vary by specification and can be credited against a formal order. Quotations are provided based on your requirements and quantity.
Standard models have an MOQ of 1,000–2,000 pieces; custom models range from 2,000–5,000 pieces depending on complexity. Lead time for standard stock orders is 7–15 days; custom orders require 25–35 days after sample approval.
Under normal household use (8 hours per day), we recommend replacement every 6–12 months. In commercial high-load environments, replace every 3–6 months. Actual intervals depend on operating conditions and air quality.
The filter is produced in IATF 16949-certified facilities and complies with ISO 9001, ISO 14001, and ISO 45001. Products meet REACH and RoHS requirements, and we can provide compliance documentation. Our CNAS-accredited laboratory issues test reports for filtration performance.
