The Zanxis washable activated carbon odor filter is a reusable composite carbon fabric designed to remove cooking odors and harmful gases such as formaldehyde, benzene, and ammonia while also capturing larger particles like hair and dust. It is intended for range hoods, integrated stoves, air purifiers, fresh air systems, car cabin filters, central air return grilles, and industrial vacuums. This filter is available in custom sizes and thicknesses, making it suitable for both OEM and ODM projects.

Before specifying this filter, we recommend confirming the following parameters with our technical team: the required thickness (available from 3 mm to 50 mm), the pore density (PPI) that matches your airflow and pressure drop requirements, the desired activated carbon content and distribution, and the exact dimensions and shape for die-cutting. Additionally, clarify the operating conditions such as temperature, humidity, and the presence of oils or solvents, as these affect adsorption performance and filter life. For applications requiring specific certifications or compliance documentation, please inform us in advance so we can provide the relevant test reports.
The filter is constructed from a polyurethane foam substrate into which activated carbon is firmly fixed using a special curing process. This composite structure allows the filter to be washed with water and neutral detergent, removing surface oils and dust while restoring airflow. The carbon content and distribution are controlled to ensure consistent adsorption of odors and gases. The material is highly flexible, enabling die-cutting into complex shapes to fit tight spaces. Typical installation includes range hoods, integrated stoves, air purifiers (as a pre-filter), fresh air systems, car cabin air filters, central air return grilles, and industrial vacuums. The filter can be used as a standalone odor filter or as a pre-filter to extend the life of higher-efficiency filters. Its low air resistance helps maintain system airflow and reduce energy consumption.
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 resistance. The production facility covers 50,000 m², including 6 clean workshops totaling 20,000 m². We are certified to IATF 16949 (achieved in 2024) and hold ISO 9001, ISO 14001, and ISO 45001 certifications. Products comply with REACH and RoHS regulations, and we can provide compliance documentation. With over 20 years of experience in filter development and manufacturing, we have exported to Europe, the US, Japan, and South Korea for more than 20 years. We support OEM/ODM projects with customization of size, structure, filter grade, frame material, logo, and packaging, and have developed over 1,000 filter solutions. Multiple automated production lines enable monthly capacity of millions of pieces. Quality control follows IQC, IPQC, and OQC processes throughout production.
To request samples and test reports, please provide the following details: your device or vehicle model, required dimensions or a drawing, airflow or water flow rate, operating conditions (temperature, humidity, contaminants), and estimated quantity. Our team will respond with a tailored proposal and sample lead time. Contact us to discuss your project.
Yes, we can provide test reports from our CNAS-accredited laboratory for parameters such as initial efficiency, pressure drop, and dust holding capacity. These reports are typically included with samples. For specific certification needs, please inform us in advance.
Custom samples are usually prepared within 7–15 days. After you receive the samples, you can conduct your own evaluation; we recommend allowing 1–2 weeks for installation and performance verification. We support you throughout the process.
For custom OEM products, the MOQ is generally 5,000 pieces. For standard specifications, the MOQ can be lower; please contact us with your requirements for a specific quote.
Standard lead time is 25–35 days after sample approval and receipt of deposit. For large or customized orders, we will confirm the schedule based on production planning. Our automated lines ensure reliable delivery.
Under normal household use, we recommend replacing the filter every 6–12 months. Washing with warm water and neutral detergent can restore airflow and extend life, but adsorption capacity will gradually decline. Replace when odor removal performance drops noticeably.
Yes, we offer full OEM/ODM customization. You can specify dimensions, thickness (3 mm–50 mm), pore density (PPI), activated carbon content, shape, and packaging. Our engineers will work with you to develop a filter that fits your device.
Our composite carbon fabric filter achieves an initial odor removal efficiency of over 85% for typical cooking odors and harmful gases like formaldehyde, benzene, and ammonia. Actual performance depends on your specific application and conditions; we can provide test data upon request.
Yes, we provide standard samples free of charge (freight collect). For custom samples, a sample fee may apply, which is refundable upon bulk order. Samples come with test reports to facilitate your evaluation. Please contact us with your specifications.
