The Jyntrel washable activated carbon odor filter is a composite carbon fabric designed to remove odors and harmful gases from airstreams while also providing initial particle capture. It adsorbs formaldehyde, benzene, ammonia, and cooking odors, and is suitable for range hoods, integrated stoves, air purifiers, and HVAC pre-filtration. Engineers and product teams specify it where low airflow resistance, repeated washing, and flexible sizing are required.
This filter is typically installed as a first-stage or pre-filter layer, directly in the air path before finer filters or heat exchangers. Its open-cell polyurethane sponge structure, combined with evenly distributed activated carbon, allows air to pass through with minimal pressure drop. In kitchen exhaust systems, for example, it captures grease and odor before they reach the blower or ductwork, helping to maintain fan efficiency and reduce odor emissions. The low airflow resistance makes it compatible with systems operating at face velocities up to several meters per second, depending on thickness and media grade. Because the media is flexible, it conforms to curved or irregular mounting spaces, ensuring a tight seal without bypass. The washable design allows periodic cleaning to restore airflow, making it a practical choice for applications where maintenance access is limited.
The filter combines two functions: initial filtration of large particles such as hair and dust, and adsorption of odorous and irritant gases including formaldehyde, benzene, and ammonia. The activated carbon is fixed onto the sponge using a specialized curing process, so it does not easily migrate or fall out during handling or washing. This construction also gives the media high flexibility, allowing it to be cut, punched, or formed into complex shapes without cracking. The open-pore structure ensures excellent air permeability, keeping pressure drop low even at higher airflow rates. While washing with warm water and mild detergent can remove surface contaminants and restore airflow, the adsorption capacity gradually declines over time, so replacement is recommended when odor breakthrough is detected.

This filter is used in residential and commercial air handling systems where odor control and pre-filtration are needed. Common installations include range hoods and integrated stoves, where it captures cooking fumes and grease; air purifiers, as a first stage to protect HEPA or carbon filters; fresh air ventilation systems, to reduce outdoor odors and pollutants; car air conditioning filters; central air conditioning return air grilles; and industrial vacuum cleaners. The flexible media can be die-cut to fit specific housing shapes, making it suitable for retrofits and OEM designs.
Jyntrel operates a 50,000 m² manufacturing facility in Zhongshan, Guangdong, China, including six clean workshops totaling 20,000 m². Multiple automated production lines enable a monthly output of millions of pieces, ensuring stable supply for large-volume orders. The company has over 20 years of experience in filter research, development, and manufacturing, with products exported to Europe, the US, Japan, and South Korea for more than two decades. Quality is managed through IQC, IPQC, and OQC procedures, and the on-site CNAS-accredited laboratory can provide test reports for filtration efficiency, dust holding capacity, and airflow resistance. Jyntrel is certified to ISO 9001, ISO 14001, ISO 45001, and IATF 16949, and products comply with REACH and RoHS requirements.

Our engineers will review your airflow, space constraints, and maintenance schedule to propose the most suitable filter configuration. Send your inquiry and we will respond promptly with a solution-oriented proposal.
Yes, the open-cell structure and low airflow resistance allow the filter to operate at face velocities typical of kitchen exhaust and HVAC systems. However, the exact pressure drop depends on thickness and PPI, so please provide your airflow rate for a precise recommendation.
We need the volumetric airflow rate (m³/h) or face velocity (m/s) at the filter location, along with the expected operating temperature and any contaminants present. This helps us select the right thickness and carbon loading.
The initial odor removal efficiency can reach over 85% for typical cooking odors and gases like ammonia and hydrogen sulfide. Under normal household use, we recommend replacement every 6–12 months, as adsorption capacity declines with use.
Yes, the filter is washable with warm water and mild detergent. Washing restores airflow by removing surface grease and dust, but the activated carbon's adsorption capacity gradually decreases over time, so replacement is still needed periodically.
Yes, we offer full OEM/ODM customisation. We can produce filters in thicknesses from 3 mm to 50 mm, various pore densities, and custom outlines using die-cutting. Please provide a drawing or dimensions for a precise quote.
Standard sizes typically have an MOQ of 1,000–3,000 pieces, while custom OEM orders usually start at 5,000 pieces. Lead time is 25–35 days for regular orders, and we can adjust for large or custom projects.
Yes, we provide standard samples free of charge (freight collect). Custom samples are quoted based on specifications, with a sampling lead time of 7–15 days. Samples include test reports from our CNAS laboratory.
We follow IQC, IPQC, and OQC procedures throughout production, and our CNAS-accredited lab tests key parameters such as carbon content, odor removal efficiency, and airflow resistance. This ensures each batch meets your specifications.
