Our cone-shaped HEPA filters can achieve filtration efficiencies of H11-H13, with a filtration efficiency of ≥99.95% for 0.3μm particulate matter, effectively intercepting fine dust, pollen, mites, and PM2.5. The product structure adopts a conical pleated design, increasing the effective filtering area and reducing airflow resistance. We have provided supporting filters for several mainstream handheld vacuum brands in Europe, America, and Japan, and can develop 1:1 matching solutions based on customer model drawings or samples to ensure perfect compatibility.

In a regular home environment, we recommend a replacement cycle of 3-6 months, depending on usage frequency and environmental dust load. We offer two filter material options: disposable HEPA filters (non-washable, higher filtration precision) and washable HEPA filters (made with a special composite material, can be washed 10-30 times). Customers can choose different options based on product positioning and market demand. Our CNAS laboratory can provide a complete lifespan test report.

We fully support OEM/ODM customization. Based on over 20 years of experience in the filtration industry and accumulation of thousands of filtration solution options, we can customize entirely according to the drawings, samples, or models provided by customers, including cone dimensions, pleating, filter material grades (H11/H12/H13), end cap materials (PU/plastic/rubber), sealing ring specifications, etc. In terms of packaging, we support various customization options such as color boxes, blister packaging, neutral packaging, and customer brand logo printing to help brands go to market quickly.

The company has passed ISO 9001, ISO 14001, and ISO 45001 system certifications, and has obtained European BSC1, US EPA, NSF, and SOP certifications. In 2024, we will add IATF16949 and medical supplies GMP certifications. HEPA filter materials comply with EN 1822 standards, and we can provide compliance test reports including REACH, RoHS, and CA65, fully meeting the entry requirements for mainstream markets in the EU, US, Japan, and South Korea, assisting customers in smooth customs clearance and channel distribution.

JND has a 50,000㎡ factory, of which 20,000㎡ comprises 6 clean rooms, ensuring that HEPA filters are produced in a dust-free environment to avoid secondary pollution. The company is equipped with a national-level CNAS accredited testing center, where each batch of products undergoes full inspections for filtration efficiency, airflow resistance, dust-holding capacity, and leakage rate. From raw material entry, semi-finished product sampling to finished product outbound, we implement a three-tier quality control process to ensure product consistency and stability, with zero deviation between bulk production and samples.

The standard MOQ for stock products is usually 3,000 pieces, while the MOQ for customized molding products is determined based on specific specifications, generally starting at 5,000 pieces. The usual order delivery time is 25-35 days after placing the order, and it's recommended to confirm production scheduling in advance during peak seasons or large orders. We possess multiple automated production lines and sufficient raw material reserves to ensure stable delivery for large orders. Long-term partners can also enjoy VMI inventory management services.

Standard stock samples can be provided for free (customers bear the shipping costs), while customized samples incur a sample fee depending on development complexity, which can be refundable upon placing an order for mass production. Our CNAS testing center can provide customers with complete testing data reports on filtration efficiency, resistance, dust-holding capacity, temperature and humidity tolerance, etc., assisting customers in completing certification applications and market testing for their end products, providing one-stop technical support from samples to mass production.

JND was established in 2002, and for more than 20 years, our products have been steadily exported to multiple countries in Europe, the US, Japan, and South Korea, serving many internationally renowned brand owners and traders. We are familiar with various trade terms such as FOB, CIF, and DDP, and support multi-modal transport including sea freight, air freight, and express delivery. The company is equipped with a professional foreign trade team and English-speaking technical engineers, providing full-process services from product development, sample confirmation, mass production follow-up, to after-sales issue response, with a delivery punctuality rate exceeding 98%.
