Conical HEPA Filter for Handheld Vacuums

This conical HEPA filter element from Jyntrel is designed for handheld vacuums, robot vacuums, mattress cleaners, wet-dry vacs, and car mini vacuums. It captures fine dust, PM2.5, dust mites, pollen, and hair from the airstream before it leaves the dust cup. It suits appliance brands and OEM teams who need a drop-in or custom-shaped filter that keeps airflow high and protects the motor. Jyntrel manufactures it in Zhongshan, Guangdong, with PTFE membrane, composite PP, or antibacterial filter media.

Operating Conditions and Airflow Path

In a handheld vacuum, the filter sits downstream of the dust cup and upstream of the motor. Air leaves the cup carrying fine particles, passes through the conical pleats, and exits to the motor and exhaust. The filter therefore has to hold dust without adding much resistance. High-porosity media and a conical fold pattern give a large effective area in a small housing, keeping pressure drop low as the filter loads. That helps maintain suction and battery run time while preventing motor overheating.

The operating environment matters. In a home, the filter sees dust, hair, and lint at room temperature. In a mattress cleaner, fine skin flakes and mite debris load the media quickly. In a car vacuum, temperature swings and vibration are common. Jyntrel selects media and pleat geometry for the target device and use pattern. Sealing is handled by an injection-moulded frame or a rubber gasket edge, so the filter fits the housing and limits dust bypass. The conical shape fits the tapered filter chamber used in many cordless stick vacuums.

Core Performance

The filter is built around three functions. First, fine-particle capture: the PTFE membrane and composite PP layers block PM2.5, dust mites, pollen, and hair, reducing secondary pollution from the exhaust. Second, low airflow resistance: the pleated cone geometry and high-porosity media keep resistance low, which supports stable suction and reduces motor load. Third, washability options: PTFE membrane versions can be washed and reused, while disposable HEPA versions prioritise filtration efficiency.

Jyntrel offers efficiency grades from H11 to H13. H13 media captures ≥99.95% of 0.3 μm particles. The conical pleat design increases surface area, so the filter holds more dust before resistance rises. For appliance makers, this balance between efficiency and pressure drop is the key selection point. The filter is not a standalone air purifier; it is a component tuned to the vacuum's airflow path and motor characteristics.

Selection and Customisation: the Data We Need

Because filter performance depends on the device, Jyntrel quotes from device data rather than from a catalogue number alone. To recommend the right media, pleat count, and frame, we ask for:

• Device model or a 2D/3D drawing of the filter chamber, or a physical sample.
• Target airflow or air velocity at the filter, if available.
• Operating environment: household dust load, pet hair, mattress use, or car cabin.
• Whether the filter should be washable or disposable.
• Required efficiency grade (H11–H13) and any compliance documents needed.
• Annual quantity and packaging requirements.

With these inputs, Jyntrel can match the conical dimensions, pleat count, end-cap material, and seal type. We support OEM/ODM customisation of size, structure, media grade, frame material, logo, and packaging. Over 1,000 filter solutions have been developed, and our team can work from a drawing, a sample, or a device model to build a 1:1 fit.

Parameters

Typical Applications

This conical filter element is used in handheld cordless vacuums, where space is tight and airflow must stay high. In robot vacuums, the conical shape fits compact filter bays and helps maintain suction as the bin fills. Mattress mite removers use the filter to trap fine dust and allergens close to the fabric surface. Wet-dry vacuums and car mini vacuums benefit from the low-resistance media when the motor runs at high speed. In each case, the filter is matched to the device's airflow path, dust load, and cleaning cycle.

Manufacturing and Testing at Jyntrel

Jyntrel operates multiple automated production lines with monthly capacity in the millions of pieces, which supports stable supply for appliance programmes. The 50,000 m² plant in Zhongshan, Guangdong, includes six clean workshops totalling 20,000 m². Filter media and finished elements are handled in controlled environments to limit contamination before packing.

The on-site laboratory is CNAS-recognised and can issue test reports for filtration efficiency, dust-holding capacity, and airflow resistance. Jyntrel holds ISO 9001, ISO 14001, and ISO 45001 system certifications, and has been IATF 16949 certified since 2024. Products meet REACH and RoHS requirements, and compliance documents can be provided. Quality control runs through IQC, IPQC, and OQC, so incoming media, in-process pleating and sealing, and finished filters are checked in sequence. With more than 20 years of export experience to Europe, the United States, Japan, and Korea, Jyntrel understands the documentation and consistency that appliance brands require.
