Our dust box HEPA filters are made with high-quality meltblown filter materials, achieving a filtration efficiency of H11-H13 levels (≥95%-99.97% for 0.3μm particles), effectively intercepting small particles such as dust, pollen, pet dander, and PM2.5. The filters are designed to be washable, extending their lifespan. We provide compatible filters for multiple mainstream international robotic vacuum brands and can offer 1:1 mold customization based on your model’s blueprint or samples, compatible with leading brands like iRobot, Xiaomi, Roborock, Ecovacs, and Dyson.

Yes, Cleantop has over 20 years of experience in the research and manufacturing of filtration products, with complete OEM/ODM capabilities. We can customize filter dimensions, shapes, filter grades (H11/H12/H13), frame materials (PP/ABS/paper frames), colors, and packaging (color boxes, blister packs, neutral packaging, brand LOGO printing, etc.) according to customer requirements. Our R&D team can provide design solutions and samples within 3-7 working days to ensure perfect compatibility with your robotic vacuum’s dust box.

Cleantop has passed ISO 9001, ISO 14001, and ISO 45001 system certifications, and has newly obtained IATF16949 automobile industry quality management certification and GMP certification for medical supplies in 2024. On the product level, we have international certifications like BSC1 in Europe, EPA, NSF, and SOP in the US, with filter materials compliant with REACH and RoHS environmental standards, fully meeting the compliance entry requirements of mainstream markets in Europe, the US, Japan, and South Korea, and can provide complete compliance documentation support to customers.

Cleantop is located in Zhongshan, Guangdong, with a factory area of 50,000㎡, including six clean rooms totaling 20,000㎡, ensuring production of filters in a dust-free environment to avoid secondary contamination. We have a national CNAS-recognized testing center that conducts all tests for filtration efficiency, resistance, dust holding capacity, airtightness, and more. Every batch of products undergoes a three-tier quality control process: IQC incoming inspection, IPQC process inspection, and OQC shipment inspection, ensuring consistent performance across batches.

Our washable HEPA filters are made with specially hydrophobic-treated composite filter materials and enhanced structural frames, designed to be washed 20-30 times under normal usage conditions, with a recommended lifespan of 3-6 months (depending on usage frequency). Testing in CNAS laboratories has verified that the filtration efficiency decay within the stipulated washing times is controlled within 5%, ensuring stable and reliable performance. We can provide customized solutions for different washability levels based on customer market positioning.

For standard models, we can provide 1-3 free samples (freight collect); for customized samples, a sampling fee will be charged based on mold complexity (which can be offset after placing a bulk order). The standard sampling cycle is 3-7 working days, while customized mold samples take about 10-15 working days. The typical MOQ for bulk orders is usually 1000-3000 pieces (depending on specifications), but we can also flexibly negotiate the initial order quantity based on the customer’s market promotion stage.

The MOQ for standard specification products is usually 5,000-10,000 pieces, while the MOQ for customized products is negotiated based on the complexity of specifications. In terms of delivery cycle, the lead time for in-stock standard products is about 7-15 days; for customized orders (including mold), it is typically 30-45 days, depending on order confirmation. Our company has a complete supply chain and scalable production capacity to meet customer needs for quick reorder and large batch delivery.

We provide a 12-month warranty for all outbound products. If quality issues arise due to manufacturing defects, we will offer free replacement or refunds based on the proportion confirmed by retest in a CNAS laboratory, and Cleantop will bear the associated shipping costs. The company has a dedicated overseas customer service team, available 24/7 to respond to customer inquiries, relying on over 20 years of B2B export service experience to provide stable and reliable after-sales support to many brand customers in Europe, the US, and Japan.
