Anti-Mite HEPA Filter for Air Purifiers and Air Conditioners

Oltaven Anti-Mite HEPA Filter is a finished composite filter that combines HEPA particle removal with anti-mite and antibacterial/antiviral functions. It captures PM2.5, pollen, pet dander, cigarette smoke, and microbial aerosols, and is tested to remove up to 82.4% of dust mites under the FZ/T01100-2008 standard. It is designed for air purifiers, car air purifiers, fresh-air air conditioners, mite-removal vacuum cleaners, and maternal-infant health appliances, and is available through full-size OEM/ODM customisation.

From Media to Finished Filter

A filter’s performance is set by the media inside it, but the finished filter you receive is the result of how that media is pleated, framed, and sealed. The media determines the starting point: fibre diameter, basis weight, and the choice of glass fibre or meltblown PP composite set the base efficiency and resistance. Pleating increases the surface area packed into a given footprint, which lowers face velocity and resistance while raising dust-holding capacity. Framing and sealing hold the pleat pack in shape, prevent air from bypassing the media, and define how the filter fits the device.

Oltaven supplies finished filters, not just media. That means we control the pleat height, pleat count, frame material, and sealing method as part of one product. A change in pleat count or frame design can shift resistance and efficiency in ways that media data alone cannot predict. By building and testing the complete filter, we can match the media to the application and deliver consistent performance that device makers can rely on.

What Decides Finished Performance

Three factors decide the finished filter’s efficiency, resistance, and capacity: media choice, pleating, and framing/sealing.

Media choice sets the baseline efficiency. For anti-mite HEPA filters, we use high-quality glass fibre or meltblown PP composite media with optional antibacterial/anti-mite coatings such as silver ion or plant essential oil coatings. This combination provides dual protection: high particle capture plus suppression of bacteria and viruses including influenza A virus, E. coli, and Staphylococcus aureus.

Pleating determines the balance between resistance and capacity. More pleats in the same frame mean more media area, lower air velocity through the media, and lower resistance, while also increasing the amount of dust the filter can hold before it loads up. Fewer, deeper pleats may suit a different airflow or space constraint. We adjust pleat count and pleat height to match the target device’s airflow and pressure budget.

Framing and sealing ensure the air goes through the media rather than around it. A well-formed frame holds the pleat pack flat, protects the media during handling, and provides a stable fit in the device. Sealing the media to the frame prevents bypass, which would otherwise reduce overall efficiency regardless of media quality. We support panel, cylindrical, and V-bank folded constructions, so the same core media can be built into different form factors.

Together, these choices decide the finished filter’s efficiency (H11 to H14 under EN 1822, with up to 99.995% efficiency at 0.3 µm in our standard range), its initial resistance, and its dust-holding capacity. All finished filters are scanned and tested in our CNAS-accredited laboratory to verify performance.

Applications

The Oltaven Anti-Mite HEPA Filter is used in household air purifiers, car air purifiers, fresh-air air conditioners, mite-removal vacuum cleaners, and maternal-infant health appliances. In these devices, it captures PM2.5, pollen, pet dander, cigarette smoke, and microbial aerosols, while the anti-mite function addresses dust mites and their allergens. For devices with specific space or airflow requirements, we can customise dimensions, shape, and filter efficiency.

OEM/ODM Workflow

1. Customer provides specifications, drawings, or device requirements.
2. Our engineering team confirms the technical proposal and provides a quotation.
3. Customer confirms the proposal and places a sample order (if required).
4. Sampling: 3–7 working days for standard samples; 3–10 working days for custom samples.
5. Customer approves the sample.
6. Mass production: 15–25 days for standard products; 25–40 days for custom products.
7. Quality inspection and delivery with COA (Certificate of Analysis) for each batch.

We support customisation of size, structure, filter media grade, frame material, logo, and packaging. Our automated production lines and monthly capacity of millions of pieces allow us to handle large orders and urgent replenishment.
