This conical HEPA filter element is a replacement filter for handheld vacuums, robot vacuums, and mattress cleaners. It captures fine dust, PM2.5, dust mites, pollen, and hair from the airstream before it leaves the dust cup, helping prevent secondary pollution. It is designed for vacuum manufacturers, brand owners, and aftermarket suppliers who need verified filtration performance and custom fit. Zanxis manufactures it with PTFE membrane or composite PP media, and each batch is supported by in-house CNAS-accredited testing.

Before you approve a sample, we recommend confirming the filtration efficiency grade you require (H11 to H13), the expected dust holding capacity for your target market, and the initial resistance at your device's rated airflow. These three values determine how the filter performs in real use and how often it needs replacement. Also confirm the exact dimensions of your dust cup and air duct, including the sealing surface, because a 1 mm mismatch can cause dust bypass. Finally, decide whether you need a washable or disposable media option, as this affects the filter's service life and the end-user experience.
We verify each of these parameters through our CNAS-accredited laboratory, and we can provide test reports for efficiency, dust holding, and resistance. Our engineering team will work with your drawings or physical samples to ensure the filter matches your device exactly.
The filter uses a conical pleated design that increases the effective filtration area while keeping the overall size compact. The pleats are made from high-precision PTFE membrane, composite PP melt-blown, or antibacterial treated filter paper, depending on the required efficiency and washability. The media is enclosed in an eco-friendly injection-molded frame, and a rubber sealing ring is applied to the edge to ensure a tight fit and prevent dust leakage.
This filter is suitable for handheld cordless vacuums, smart robot vacuums, mattress mite removers, floor washers, and car mini vacuums. Its high-porosity structure maintains low airflow resistance, which helps prevent motor overheating and supports longer battery run time. The filter can be customized in size, shape, pleat count, and frame material to match your specific device.
Our in-house laboratory is accredited by CNAS (China National Accreditation Service for Conformity Assessment) and can issue test reports for filtration efficiency, dust holding capacity, and airflow resistance. These reports give you documented performance data for your product validation and market submissions.
Quality control follows a three-stage process: IQC (incoming material inspection), IPQC (in-process inspection), and OQC (outgoing quality control). We are certified to ISO 9001, ISO 14001, and ISO 45001, and we achieved IATF 16949 certification in 2024. Our products comply with REACH and RoHS regulations, and we can provide the relevant compliance documents.
Manufacturing takes place in a 50,000 m² production base in Zhongshan, Guangdong, China, which includes six clean workshops totaling 20,000 m². With over 20 years of experience in filtration and more than 1,000 filter solutions developed, we support OEM/ODM projects with customized dimensions, structures, filter grades, frame materials, logos, and packaging. Multiple automated production lines enable a monthly capacity of millions of pieces.
To receive samples and test reports, please provide the following information: your device or vehicle model, the filter size or a drawing, the required airflow or water flow (if applicable), your operating conditions (temperature, humidity, dust load), and the estimated quantity. Our team will review your requirements and respond with a detailed proposal. Contact us to start the verification process.
Yes. Our CNAS-accredited laboratory can provide test reports covering filtration efficiency, dust holding capacity, and airflow resistance. These reports are generated from samples produced to your specifications. We can also supply compliance documents for REACH and RoHS on request.
The filter is available in H11 to H13 grades, with efficiency of ≥99.95% for particles down to 0.3 μm depending on the grade. The exact efficiency is verified by our in-house lab and reported in the test documentation. We can help you select the appropriate grade for your target market.
Sample production typically takes 7–10 working days after drawing confirmation. Testing in our lab adds a few days, and then samples and reports are dispatched to you. The total time from your initial inquiry to receiving samples is usually 2–3 weeks, depending on the complexity of the customization.
For standard specifications, the MOQ is typically 3,000 pieces. For custom tooling projects, the MOQ is generally 5,000 pieces, depending on the specific design. We can discuss your requirements and provide a precise MOQ based on your configuration.
Standard orders are delivered 25–35 days after order confirmation. For large or peak-season orders, we recommend confirming the production schedule in advance. Our multiple automated lines and material stock help maintain stable delivery.
Under normal household use, we recommend replacement every 3–6 months, depending on usage frequency and dust load. We offer both disposable and washable versions; the washable version can be cleaned 10–30 times. Our lab can provide life testing reports to support your replacement recommendations.
Yes. We support full OEM/ODM customization based on your drawings or samples. We can adjust the conical dimensions, pleat count, filter grade, frame material, and sealing ring to ensure a perfect fit. Our engineering team will work with you to match your device's air duct and dust cup exactly.
Yes. We can provide samples for your evaluation. For standard specifications, samples may be free of charge, with the customer bearing the shipping cost. Custom samples may incur a fee, which is refundable upon mass production order. Please contact us with your requirements to arrange samples and test reports.
