Our plate type activated carbon cloth filter features a high-quality activated carbon layered structure, exhibiting excellent adsorption efficiency for VOCs, odors, formaldehyde, and benzene compounds, with typical removal rates of over 85% (specific data depend on gas type and airflow). Under normal working conditions, its lifespan ranges from 6 to 12 months, adjustable based on air pollution concentration and usage frequency. This product is widely used in home/commercial air purifiers, fresh air systems, central air conditioning units, industrial exhaust treatment, painting workshops, and laboratory ventilation scenarios. Our CNAS accredited testing center provides standardized performance testing reports for each batch of products.
Cleantop has passed ISO 9001, ISO 14001, and ISO 45001 management system certifications, and its products have also received international authoritative certifications such as Europe’s BSC1, the US EPA, NSF, and SGS. In 2024, we also obtained IATF16949 automotive industry certification and GMP certification for medical supplies. Our products have been successfully exported to multiple countries and regions including Europe, the USA, Japan, and South Korea, fully complying with the regulatory requirements of mainstream markets in Europe and America, and can provide customers with complete certification documents and compliance technical support.
Yes. With over 20 years of industry experience and over a thousand matured filtration solutions, we have comprehensive OEM/ODM capabilities. We can customize the filter frame material (paper frame, aluminum frame, plastic frame, etc.), size, activated carbon weight, type of carbon (coconut shell carbon, bituminous carbon, modified carbon, etc.), layered structure, and packaging solution (neutral packing, customer brand packing, color boxes, etc.) according to customer needs. Our R&D team can complete samples within 7-15 days upon receiving drawings or samples.
Cleantop operates a 50,000 m² factory, with 20,000 m² dedicated to clean rooms (a total of 6), ensuring products are manufactured in a clean and controlled environment. We are equipped with a national CNAS accredited testing center, implementing full process QC control for raw materials, semi-finished products, and finished products, key indicators include activated carbon iodine value, fabric weight, air permeability, filtration efficiency, and airtightness. With ISO 9001 and IATF16949 quality systems, we ensure consistency and stability of performance between batches.
The MOQ for standard specifications is usually 500-1000 pieces, while the MOQ for customized products is negotiated based on mold and material conditions. We can provide free samples to formal customers (shipping cost borne by the customer), and standard product samples are generally shipped within 3 working days, while the custom sampling cycle is 7-15 days. We welcome you to evaluate sample performance before deciding on bulk purchases.
The usual lead time for regular orders is 15-25 days, while bulk orders are typically 30-45 days; urgent orders can be negotiated for expedited arrangements. Our 50,000 m² production base is equipped with multiple automated production lines, ensuring ample monthly capacity, and employs an ERP system for real-time control of order progress, supported by a stable raw material supply chain to fully guarantee on-time delivery of bulk orders. We maintain long-term stable cooperation with multiple European and American brand clients, with an on-time delivery rate exceeding 98%.
The activated carbon we select comes from high-quality suppliers, with an iodine value typically between 800-1100 mg/g, and each batch of raw materials is tested for key indicators such as iodine value, CTC value, and ash content at our CNAS laboratory. For different target pollutants (such as formaldehyde, hydrogen sulfide, ammonia, acidic/alkaline gases, VOCs, etc.), we can provide modified activated carbon, impregnated carbon, or composite multi-layer carbon cloth solutions for targeted efficient adsorption. Customers can provide a list of target pollutants, and our technical team will recommend the optimal formulation.
Cleantop provides complete CNAS testing reports and factory certificates for each batch of products, and commits to free replacement or return of products due to quality issues during the warranty period. We have a dedicated overseas customer service team that offers multi-language technical support and quick responses (reply within 24 hours). Additionally, our technical engineers can assist customers with failure analysis, application optimization, and on-site testing guidance, ensuring worry-free long-term cooperation.
