HI-IN
The Thesvin anti-mite HEPA filter is a composite panel or cylindrical filter that captures fine dust and allergens and adds an anti-viral and anti-bacterial coating. It removes PM2.5, pollen, pet dander and microbiological aerosols, and is certified to achieve an 82.4% mite removal rate. It is made for air purifier and HVAC manufacturers who need a filter that seats cleanly in the host unit and performs consistently.
Fitment is the first thing we confirm. The filter is built to the drawing you supply, so the outer dimensions, frame profile and thickness match the slot or housing in your air purifier, fresh-air unit or vacuum dock. Because the filter is a multi-layer composite, we can supply it as a flat panel, a rolled cylinder or a V-bank folded cartridge, depending on how your unit loads and seals. The frame is sized to your cavity, and we keep corner radii and edge straightness within the tolerance you set so the part slides in without forcing and sits square against the housing face.
Sealing and location are treated as part of the part, not an afterthought. We agree with you where the filter registers—whether it presses against a gasket land, sits in a channel, or is held by a end cap—and we hold the dimensions that control that interface. The goal is a predictable, repeatable fit across production batches, so your assembly line does not need to rework or shim the filter. If you are replacing an existing filter, sending the old part is often faster than producing a drawing, because we can measure the frame, media pack and any locating features directly.
The core layer is a high-efficiency HEPA medium that captures suspended particles, including PM2.5, pollen, pet dander, cigarette smoke particles and microbial aerosols. The composite construction adds a coating that helps inactivate bacteria and viruses on the filter surface, including influenza A virus, E. coli and Staphylococcus aureus, as tested. The anti-mite performance is certified at an 82.4% removal rate under FZ/T01100-2008 by a national authoritative testing body.
This filter is aimed at household air purifiers, car air purifiers, fresh-air air conditioners, mite-removal vacuum cleaners and mother-and-baby health appliances. In each case the filter is matched to the airflow and pressure drop of the host device, so the unit keeps its rated clean air delivery while the filter does its job. We do not publish a single efficiency class for every build because the media grade is selected with the customer; the certified mite removal figure above applies to the tested configuration.

Thesvin holds IATF 16949 (achieved in 2024) and ISO 9001, ISO 14001 and ISO 45001 certification, and quality control runs through IQC, IPQC and OQC for dimensional consistency. Our own laboratory is CNAS-accredited and can issue reports on filtration efficiency, dust holding capacity and resistance. Production takes place in a 50,000 m² facility that includes six clean workshops totalling 20,000 m², which supports stable output and batch-to-batch repeatability. Products meet REACH and RoHS requirements, and compliance documents can be supplied.
We have more than 20 years of filter development and manufacturing experience and have exported to Europe, the United States, Japan and South Korea for over 20 years. Multiple automated production lines support monthly output in the millions of pieces. For this filter, standard models typically have an MOQ of 500–1,000 pieces, while custom models are generally 2,000–3,000 pieces depending on specification and packaging. Samples are usually ready in 3–7 working days; standard products ship in 15–25 days and custom products in 25–40 days.
To move quickly, send the device or vehicle model, the size or a drawing (or the old part), the airflow or water flow of your system, the operating conditions, and the quantity you expect. Our team in Zhongshan, Guangdong, China will confirm fitment and respond with a quotation. Contact us to start.
Fit is confirmed from your drawing, the old part or the device model. We match the frame, thickness and locating features to your housing, and we can produce flat panel, cylindrical or V-bank forms. Send the interface dimensions and we will confirm before quoting.
Yes. An old part is often the fastest route because we can measure the frame, media pack and any locating features directly. We will confirm the dimensions with you before making a sample.
The certified mite removal rate is 82.4% under FZ/T01100-2008, tested by a national authoritative body. The HEPA media grade is selected with you to suit your airflow and pressure drop budget, so efficiency is agreed per project.
Yes. We support 100% OEM/ODM customisation, including length, width, thickness, shape and filtration efficiency combinations. Frame material, media grade and packaging can also be specified.
Standard models typically have an MOQ of 500–1,000 pieces, and custom models generally 2,000–3,000 pieces. Samples are usually ready in 3–7 working days; standard production takes 15–25 days and custom production 25–40 days.
Replacement depends on the application and operating conditions. We agree a recommended interval with you during sampling so it matches the dust load and runtime of your device.
We control dimensions through IQC, IPQC and OQC, and produce in clean workshops within our 50,000 m² facility. Our CNAS-accredited laboratory tests efficiency, dust holding capacity and resistance, and we can supply compliance documents for REACH and RoHS.
Yes. Send the device or vehicle model, size or drawing (or the old part), airflow or water flow, operating conditions and quantity. Our team in Zhongshan, Guangdong, China will confirm fitment and reply with a quotation. <a href="/en/contact">Contact us</a> to start.
