Frequent replacement of purifier filter media not only significantly increases user costs but also leads to resource waste. JND has specially developed the Washable Activated Carbon Filter (Sponge Filter). The product uses polymer foam sponge as a stable carrier, with high-quality activated carbon powder firmly adhered to the surface. It serves as a perfect pre-filter, intercepting large particles of dust and hair in the air, and deeply removing harmful gases such as formaldehyde and VOCs. When the filter becomes saturated or dusty, it can be directly rinsed with water. After air-drying, the adsorption performance rapidly recovers, providing users with an unparalleled cost-performance experience.
Get Custom Washable Filter SolutionsStandard activated carbon filters can only be discarded when saturated or dusty. Our sponge activated carbon filters utilize a special carbon solidification process, allowing users to rinse the filter with water when dust or odors accumulate. After air-drying, the microporous structure is released, enabling multiple cycles of use, greatly enhancing product economic efficiency.
It is the best partner to protect expensive HEPA filters. Its polymer sponge structure is designed to intercept hair, cotton fluff, and large dust particles in the air first; at the same time, the evenly distributed high-quality activated carbon effectively adsorbs harmful volatile gases such as formaldehyde, benzene, ammonia, and other odors, achieving a perfect combination of physical interception and chemical adsorption.
Compared to rigid folded filters or honeycomb blocks, sponge materials provide excellent flexibility and plasticity. Whether it is narrow car air conditioning ducts, curved fresh air system pipes, or various uniquely shaped air purifiers, they can perfectly fit the air outlet. JND supports 100% stamping processing and thickness customization according to drawings.

Whether you are looking for washable primary filtration media to reduce consumable replacement frequency or need to customize ultra-low air resistance activated carbon sponge modules for your vehicle or fresh air system, JND, with over 20 years of research and manufacturing experience and a national-level CNAS testing center, will be your best choice.
Contact the Engineering Team / Request Filter Cotton Samples and Custom QuotesOur composite carbon fabric odor filter utilizes high specific surface area activated carbon combined with fiber cloth, exhibiting excellent adsorption performance for oily fumes and odors (such as hydrogen sulfide, ammonia, cooking oil fumes, etc.). The initial odor removal efficiency can reach over 85%. Under normal home use conditions, the recommended lifespan is 6-12 months; it can partly restore adsorption performance by washing with warm water, extending its service life. Specific parameters can be provided through customized testing reports from our CNAS testing center based on the customer's application scenario.
Yes, this product features a washable design, employing a special composite process to solidify activated carbon onto the base cloth. It can be gently rinsed with neutral detergents combined with warm water to remove surface grease residues. After cleaning, airflow resistance returns to good levels, but due to the physical adsorption characteristics of activated carbon, odor removal capability gradually declines with usage time. It is recommended to regularly replace the filter based on odor removal effectiveness. We can provide cleaning guidelines and washing durability test data for reference.
Absolutely. JND has over 20 years of experience in developing and manufacturing filter products, with over 1,000 filtration solutions available. We can customize filters according to customer needs regarding size, shape, weight, activated carbon content, frame material (aluminum/frame/no frame), and packaging solutions (color boxes, blister packs, private labels, etc.). Our professional R&D team and CNAS laboratory enable quick responses to OEM/ODM projects, typically completing sampling to mass production in 4-6 weeks.
JND has obtained ISO 9001, ISO 14001, and ISO 45001 certifications, along with international certifications such as European BSC1, US EPA, NSF, SOP, etc. In 2024, we updated to gain IATF16949 and medical GMP certifications. Our range hood filter products can provide compliance testing reports for RoHS, REACH, LFGB, meeting entry requirements for the mainstream markets in Europe, the USA, Japan, and South Korea.
JND operates a 50,000㎡ factory, including 20,000㎡ of clean workshops (6 in total), equipped with a national-level CNAS testing center. We implement a comprehensive quality control system from incoming material inspection (IQC), production process control (IPQC), to finished product outgoing inspection (OQC). Key indicators such as activated carbon content, odor removal efficiency, air resistance, and tear strength are strictly tested to ensure stable and consistent product quality, meeting the long-term stable supply needs of B2B customers.
The MOQ for standard specification products is usually 1,000-3,000 pieces, depending on style and packaging; the MOQ for customized OEM products generally starts at 5,000 pieces. Normal order lead time is 25-35 days. For large volume or custom projects, delivery can be negotiated based on production scheduling. We have multiple automated production lines and sufficient capacity reserves to effectively guarantee timely delivery during peak seasons and large orders.
Yes. We support providing standard samples for customers to conduct physical testing and market assessments. Normally, standard samples can be provided for free (shipping costs are borne by the customer). For customized samples, we will quote based on specific specifications, with a sampling period typically ranging from 7 to 15 days. Samples will include testing reports issued by our CNAS laboratory for customer performance verification and compliance audits.
We offer flexible packaging solutions, including color box packaging for customer brands, independent packing in PE bags, and labeling on outer cartons. All packaging materials comply with environmental requirements. Before exporting, the products undergo moisture and pressure protection to ensure they remain intact during long-distance sea transport.
