The Ranveth cylindrical anti-bacterial and anti-virus filter is a multi-layer composite filter with a 360° pleated annular structure, designed to capture PM2.5, pollen, pet dander, cigarette smoke, and microbial aerosols while inhibiting influenza A virus, E. coli, and Staphylococcus aureus. It is intended for high-end car air purifiers, household and desktop compact air purifiers, and mother-and-baby health appliances. The filter pairs a HEPA media layer with an anti-bacterial/anti-virus coating, and the way these media are combined determines efficiency, airflow resistance, and service life.
The cylindrical filter is built as a multi-layer functional composite. A high-density HEPA pleat pack forms the core, capturing fine particles such as PM2.5, pollen, pet dander, cigarette smoke, and dust aerosols. An anti-bacterial and anti-virus treatment is integrated into the media to inhibit influenza A virus, E. coli, and Staphylococcus aureus. The 360° annular pleated structure allows air to enter from all sides, increasing the effective filtration area within a compact footprint and helping to maximize clean air delivery rate (CADR) without excessive pressure drop.
Media pairing is the key engineering decision. The HEPA layer must be efficient enough to meet particle capture targets, yet open enough to keep resistance low for the fan. The anti-bacterial/anti-virus layer adds biological inhibition without blocking airflow. Ranveth balances these factors by selecting media grades and pleat geometries that match the target device's airflow and resistance requirements. The result is a filter that maintains efficiency over its service life while keeping energy use and noise within the appliance's design envelope.
For buyers, this means the filter is not a commodity pleat pack. The interaction between layers determines how often the filter needs replacement, how much the motor has to work, and how consistently the device performs in real rooms. The cylindrical format also simplifies sealing and installation in compact purifiers, where every millimeter of media area counts.
The filter is available with customized outer diameter, inner diameter, height, and filtration efficiency ratios, supporting OEM/ODM tooling and production. This flexibility lets device makers tune the media pairing to their specific CADR targets and noise constraints.

The cylindrical format suits appliances where space is tight and airflow must be high. Typical installations include high-end car air purifiers, where the filter must fit behind trim panels and handle vibration while maintaining cabin air quality. Household and desktop compact air purifiers benefit from the 360° intake, which draws air from all directions and supports a smaller device footprint. Mother-and-baby health appliances use the anti-bacterial and anti-virus properties to help reduce microbial load in nurseries and bedrooms.
Because the filter can be customized in diameter, height, and efficiency, it also fits secondary applications such as small fresh-air units or specialty purifiers where a cylindrical cartridge is preferred. In each case, the media pairing is adjusted to the device's airflow and resistance budget, so the filter performs as an integrated component rather than an afterthought.
To quote a custom cylindrical filter, we need a few practical details. Please provide the device or vehicle model and the available installation space, ideally with a dimensioned drawing or a physical sample. Specify the required outer diameter, inner diameter, and height, or let us know the target airflow and allowable pressure drop. Operating conditions matter: typical run hours per day, ambient dust loading, humidity, and temperature. Finally, tell us your expected order quantity and any efficiency or certification requirements. With these inputs, our engineers can propose a media pairing and pleat geometry that meets your performance and cost targets.
Ranveth backs its media choices with test data. Our in-house laboratory is CNAS-accredited and can issue reports on filtration efficiency, dust holding capacity, and resistance, so you can verify performance before committing to production. The filter is manufactured in a 50,000 m² plant that includes six cleanrooms totaling 20,000 m², supporting consistent quality for sensitive applications. We are certified to IATF16949 (2024) and hold ISO 9001, ISO 14001, and ISO 45001 system certifications. Products comply with REACH and RoHS environmental regulations, and compliance documents are available on request. With more than 20 years of filtration experience and exports to Europe, the US, Japan, and South Korea, we understand the documentation and consistency that international buyers require.
If you are evaluating a cylindrical filter for an air purifier or car cabin application, we can supply samples and a quotation based on your specifications. Share your device model, dimensions or drawing, airflow or water flow requirements (as applicable), operating conditions, and estimated quantity. Our team will respond with a proposal, sample lead time, and pricing. To start the conversation, contact us.
It combines a high-density HEPA pleat pack with an anti-bacterial and anti-virus treatment in a multi-layer composite. The HEPA layer captures PM2.5, pollen, pet dander, and smoke particles, while the treatment inhibits influenza A virus, E. coli, and Staphylococcus aureus.
The 360° annular pleated design increases media area, which supports higher clean air delivery rate (CADR) while keeping pressure drop within the appliance's fan capability. The media pairing is tuned so that the HEPA efficiency and anti-bacterial layer do not create excessive resistance.
The mite removal rate is up to 82.4%, tested by a national authoritative institution with reference to the FZ/T01100-2008 standard. This figure is specific to this cylindrical filter model.
Yes, we support OEM/ODM customization. You can specify outer diameter, inner diameter, height, and filtration efficiency ratios, and we will tool and produce to match your device's airflow and space requirements.
For this product, standard models typically have an MOQ of 1000–2000 pieces, while customized models range from 2000–5000 pieces depending on complexity. Lead time is 7–15 days for standard stock orders and 25–35 days for custom orders after sample approval.
Yes. Standard samples can be shipped within 3–5 working days, and custom samples typically take 7–15 working days to develop. Sample costs vary by specification and can be credited against a formal order; samples come with a CNAS laboratory performance report.
Under normal household use (about 8 hours per day), we recommend replacement every 6–12 months. In commercial high-load environments, 3–6 months is advisable. Actual life depends on dust loading and operating conditions.
The HEPA media is designed to capture PM2.5, pollen, pet dander, and smoke particles with high efficiency, and the anti-bacterial/anti-virus function inhibits influenza A virus, E. coli, and Staphylococcus aureus. For project-specific efficiency data, please contact us with your requirements.
