Dust Box HEPA Filter for Robot and Handheld Vacuums

This is a dust box HEPA filter for robot vacuums and handheld vacuums, built to capture PM2.5, fine dust, dust mites, pollen and pet dander before air leaves the machine and re-enters the room. It is made with high-precision PTFE microporous membrane or composite PP meltblown media, and is supplied by Jyntrel as a washable filter in custom sizes. It suits vacuum OEMs, appliance brands and aftermarket programmes that need a low-resistance filter matched to a specific dust box.

Operating Conditions and Airflow Path

In a robot vacuum or handheld unit, the filter sits at the end of a short, fast air path. The motor pulls air through the dust box, and the filter is the final barrier before exhaust. That position defines the requirements: the media must hold fine particles while adding as little resistance as possible, because every extra pascal of pressure drop is taken directly from suction at the floor nozzle and from battery runtime.

Jyntrel approaches this as a system question rather than a material question. We look at the airflow the motor delivers, the face velocity across the filter, the dust load the bin is expected to hold, and whether the filter will be washed. A high-porosity breathing design keeps restriction low during normal operation, while the PTFE membrane layer provides the fine-particle barrier. The same logic applies to handheld vacuums, bed mite removers, car mini vacuums and wet-dry floor cleaners, where dust box geometry and airflow differ from model to model.

Because dust boxes are compact, filter area is limited. The design therefore balances media grade, pleat or frame geometry and sealing at the edge so that air passes through the media rather than around it. Edge sealing is handled with an overmoulded rubber edge where the housing requires it.

Core Performance

The filter is specified for strong interception of PM2.5, fine dust, dust mites, pollen and pet dander, which prevents the secondary pollution that occurs when exhaust air carries fine particles back into the room. The microporous structure is the main capture layer; the composite PP meltblown grades provide graded filtration at lower cost, while PTFE membrane versions add a moisture-resistant, washable surface.

Low airflow resistance is the second design target. A high-porosity, breathable construction keeps pressure drop low so the motor does not lose suction and battery runtime is not shortened unnecessarily. High strength and dirt tolerance matter in this duty: dust boxes are emptied and refilled repeatedly, and washable filters are rinsed between cycles, so the media and frame must hold their shape through that handling.

Filter class is selected with the customer. H11, H12 and H13 grades are available across the range, and the final grade is fixed against the airflow data and the target market requirements for each model.

Selection and Customisation: the Data We Need

Every dust box is different, so this filter is made to the device rather than to a catalogue size. Jyntrel offers 100% customisation to the dust box dimensions, with eco-friendly injection-moulded frames and edge sealing, and supports scale production of washable PTFE-coated versions. We can also customise frame material, filter grade, colour, logo and packaging.

To quote accurately we need: the device or vehicle model, the dust box size or a drawing, the airflow the motor delivers, the operating conditions (dry dust only, or wet pickup nearby; expected wash frequency; ambient humidity), and the order quantity. With that data we can propose a media grade and frame geometry, then confirm with a sample. Where no drawing exists, a physical sample can be measured and used to build the tooling.

Parameters

Typical Applications

• Robot vacuums: dust box final-stage filters where low restriction protects suction and runtime.
• Handheld cordless vacuums: compact filter elements matched to the bin geometry.
• Bed mite removers: fine-particle capture for dust mite and dander control.
• Car mini vacuums: small-format filters for short, high-velocity air paths.
• Wet-dry floor cleaners: moisture-resistant media options where the filter sees damp conditions.

Manufacturing and Testing at Jyntrel

Jyntrel runs multiple automated production lines capable of millions of pieces per month, which supports stable supply for appliance programmes and aftermarket ranges. The company has more than 20 years of filtration product development and manufacturing experience, and has exported to Europe, the United States, Japan and Korea for over 20 years. The production base covers 50,000 m², including six clean workshops totalling 20,000 m².

Testing is carried out in the company's own laboratory, which is CNAS-accredited and can issue reports on filtration efficiency, dust holding capacity and resistance. Quality control follows IQC incoming inspection, IPQC in-process inspection and OQC outgoing inspection. Jyntrel holds ISO 9001, ISO 14001 and ISO 45001 certification, and was certified to IATF 16949 in 2024. Products meet REACH and RoHS requirements and compliance documents can be provided. The company is located in Zhongshan, Guangdong, China.
