The Thesvin cone-shaped HEPA filter is a replacement filter element for handheld vacuum cleaners, stick vacuums, robot vacuums, and mattress cleaners. It captures fine dust, PM2.5, mites, pollen, and hair from the airstream before exhaust, helping to prevent secondary pollution. It is designed for OEM and ODM customers who need a filter that matches their device's dust cup and air path, with custom dimensions and sealing options. Thesvin manufactures it in Zhongshan, Guangdong, China, under IATF 16949 and ISO 9001 quality systems.
Fitment is the first thing we confirm. The cone shape is not cosmetic: it increases the effective filter area inside a compact dust cup while leaving clearance for the motor and battery pack. The outer frame is injection-molded to the dimensions of your housing, and the sealing edge can be finished with a rubber gasket to maintain an airtight joint. That seal matters because any bypass around the filter lets dust reach the exhaust and the motor.
We match the interface to your drawing or a physical sample. Key variables include the cone's top and bottom diameters, pleat count and pleat depth, end-cap geometry, and the position of any locating tabs. Because we build to your model, you do not need to redesign the dust cup to accept a generic filter. This approach suits handheld vacuums, robot vacuums, mite removers, wet-dry vacuums, and compact car vacuums, each with its own airflow path.
The filter media is a high-precision PTFE membrane, a composite PP melt-blown layer, or an antibacterial treated filter paper. These media are selected for fine-particle capture with low airflow resistance. In a vacuum cleaner, low resistance helps preserve suction and reduces heat buildup in the motor, which can support longer battery runtime per charge. The pleated cone provides a large dust-holding capacity, so performance stays stable between cleanings.
The filter is intended for dry household dust and debris captured in the dust cup. It helps block PM2.5, dust mites, pollen, and hair from returning to the room through the exhaust. The PTFE membrane option is washable, allowing repeated cleaning within the limits of the media grade you choose. For customers who prefer a maintenance-free consumable, a non-washable HEPA option is also available.

Thesvin operates a 50,000 m² manufacturing site in Zhongshan, Guangdong, China, including six clean rooms totaling 20,000 m². Our quality system is certified to ISO 9001, ISO 14001, and ISO 45001, and we added IATF 16949 certification in 2024. IQC, IPQC, and OQC controls run through incoming material inspection, in-process checks, and final inspection, which supports dimensional consistency from sample to mass production.
Our own laboratory is CNAS-accredited and can issue test reports on filtration efficiency, dust capacity, and airflow resistance. Products comply with REACH and RoHS, and we can supply compliance documents for your market. With more than 20 years of filtration manufacturing and export experience to Europe, the US, Japan, and Korea, we support OEM/ODM projects including size, structure, filter grade, frame material, logo, and packaging customisation. Multiple automated production lines support monthly output in the millions of pieces.
To quote accurately, tell us the device or vehicle model, the filter size or a drawing, the airflow your unit requires, the operating conditions (dust load, washable or disposable), and your target quantity. Send these details through our contact page and our team will respond with fitment feedback and a quotation.
Fitment depends on the cone dimensions, pleat layout, and gasket position, so we build to your drawing or a physical sample rather than a generic size. We confirm top and bottom diameters, end-cap geometry, and locating features before quoting. Send your model number or old part and we will check the interface for you.
Yes. A used filter or a photo with basic measurements is often enough for us to reverse-engineer the interface. We measure the sample and produce a specification for your approval before sampling. This is common for older models where drawings are no longer available.
The filter is available in H11 to H13 grades, with efficiency of ≥99.95% for 0.3 μm particles at the higher grades. The cone pleat design increases effective area and keeps airflow resistance low. We can provide test data from our CNAS-accredited laboratory for the grade you select.
We offer both washable PTFE membrane versions and disposable HEPA versions. For washable types, cleaning is possible within the limits of the media, typically 10 to 30 cycles depending on the grade. In normal household use, replacement every 3 to 6 months is recommended, based on usage frequency and dust load.
For standard specifications, the MOQ is typically 3,000 pieces. Custom tooling projects usually start at 5,000 pieces, depending on the design. Standard orders ship in about 25 to 35 days after confirmation; peak-season or large orders should be scheduled in advance.
Yes. Samples can be produced for fit and airflow testing on your unit. Sample fees and lead time depend on the design complexity, and we can discuss the details when you send your request. Sample test data from our CNAS lab is available to support your evaluation.
Yes. We support OEM/ODM customisation of size, structure, filter grade, frame material, logo, and packaging, including color boxes, blister packs, and neutral packaging. With more than 1,000 filtration solutions developed, we can align the filter to your product positioning. Share your requirements through the contact page for a specific proposal.
Our quality systems are certified to ISO 9001, ISO 14001, and ISO 45001, and we obtained IATF 16949 in 2024. Products meet REACH and RoHS requirements, and we can supply compliance documents. Our CNAS-accredited lab issues reports on efficiency, dust capacity, and airflow resistance. Contact us with your market requirements to confirm the document set.
