The Jyntrel formaldehyde catalytic filter mesh is an air-purification component that decomposes formaldehyde and other volatile organic compounds at room temperature, rather than merely trapping them. It is built for residential air conditioners, stand-alone air purifiers and similar recirculating air paths where continuous low-energy removal of indoor VOCs is required. The active medium is a high-activity manganese dioxide catalyst, typically δ-MnO₂ or a composite manganese oxide, carried on a honeycomb activated-carbon, porous ceramic or fibrous composite substrate. It suits appliance makers and HVAC system integrators who need a durable, integrable filter layer with a documented CADR and a long service life.
In a typical installation, the filter sits in the return-air or process-air stream of an air conditioner or purifier, downstream of any coarse dust pre-filter. Air approaches the face of the mesh at the velocity set by the fan curve and duct geometry; the open honeycomb or fibrous structure keeps pressure drop low enough that the appliance fan can maintain its design airflow. The catalyst works by contact: formaldehyde molecules adsorb on the manganese oxide surface and are oxidised to carbon dioxide and water at ambient temperature, so no heater, UV lamp or additional power supply is needed.
The recommended operating window is 5 °C to 50 °C and 30 % to 90 % relative humidity. Within this range, the catalyst remains active across seasonal swings in a residential or light-commercial environment. Because the reaction is catalytic rather than consumptive in the manner of a simple adsorbent, the filter does not release captured formaldehyde back into the air stream under normal operating conditions; the feature is described as complete decomposition without rebound. For systems with high face velocity, we review the substrate type and pleat or cell geometry so that residence time and pressure drop remain within the appliance's fan capability.
The catalytic medium is selected for high activity and stability. Formaldehyde clean-air delivery rate (CADR) is rated at ≥ 300 m³/h, with the final figure matched to the host device through customisation. Cumulative clean-air delivery (CCM) reaches F4 level, ≥ 1500 mg, which reflects a long-life design: the catalyst is intended to keep working over an extended period rather than saturating quickly like a purely physical adsorbent.
Recommended service life is 12 to 36 months, depending on the actual pollutant concentration in the application. In spaces with higher formaldehyde loading, the lower end of that range applies; in cleaner indoor environments, the upper end is realistic. The filter is available on honeycomb activated-carbon mesh, porous ceramic cores and fibre composite media, so it can be specified to fit existing frame dimensions and air-path geometry. This combination of room-temperature catalysis, a documented CADR of ≥ 300 m³/h and an F4-level CCM gives system designers a component that can be modelled into both performance and maintenance schedules.
To recommend the right configuration, we ask for the device or vehicle model, the installation size or a drawing, the design airflow or water flow (where relevant), and the operating conditions: temperature, relative humidity, pollutant concentration and duty cycle. Quantity and packaging requirements complete the picture. With these inputs, our engineering team can propose substrate type, catalyst loading and dimensions that fit the host system without over-specifying pressure drop or cost.
As an OEM/ODM supplier, Jyntrel supports customisation of size, structure, filter media grade, frame material, logo and packaging. More than 1000 filtration solutions have been developed to date, and each project is reviewed against the customer's air path and performance targets. If you are unsure which substrate suits your appliance, share the airflow and space envelope and we will narrow the options.

This filter mesh is used in household air conditioners and air purifiers as a formaldehyde and TVOC removal stage. In air conditioners, it can be integrated as a catalytic layer in the return-air path, adding gas-phase VOC control to an existing particulate filter. In portable and central air purifiers, it serves as a dedicated formaldehyde or TVOC stage, often downstream of a HEPA or dust filter. The same catalytic media is also relevant to other recirculating air systems where low-level formaldehyde from furnishings and building materials must be reduced without adding energy consumption or maintenance complexity. Because the catalyst operates at room temperature, it is compatible with appliances that have no provision for heater power or UV lamps.
Jyntrel manufactures this catalytic filter mesh at its 50,000 m² production site in Zhongshan, Guangdong, China, which includes six clean workshops totalling 20,000 m². Multiple automated production lines support a monthly capacity of millions of pieces, and more than 20 years of continuous export experience to Europe, the United States, Japan, South Korea and other markets underpins supply stability for long-running programmes.
The in-house laboratory is CNAS-accredited and can issue test reports covering filtration efficiency, dust-holding capacity and resistance, giving customers documented performance data for their files. Quality control follows IQC, IPQC and OQC through the full process. The company holds IATF 16949 (obtained in 2024), ISO 9001, ISO 14001 and ISO 45001 certifications, and products comply with REACH and RoHS requirements, with compliance documents available on request. These capabilities support both standard and custom catalytic filter projects.
To receive a tailored recommendation, please provide the device or vehicle model, the required size or a drawing, the design airflow or water flow, the operating conditions (temperature, humidity, pollutant concentration) and the expected quantity. Our team will respond with a suitable configuration and quotation. Contact us to start the conversation.
The catalytic reaction depends on contact between the air stream and the manganese oxide surface. At higher face velocities, residence time in the filter decreases, so we review the substrate geometry and cell density to maintain performance. Please share your design airflow so we can recommend a suitable configuration.
We need the design airflow rate (m³/h) and the available pressure drop budget of your system, along with the installation dimensions. This allows us to select a substrate and catalyst loading that fits your fan curve. If you have a target CADR, please include that as well.
The formaldehyde clean-air delivery rate (CADR) is rated at ≥ 300 m³/h, and the cumulative clean-air delivery (CCM) reaches F4 level (≥ 1500 mg). Exact efficiency depends on the final filter size and the host device's airflow. We can customise the design to meet your specific efficiency target.
Yes. Jyntrel supports OEM/ODM customisation of size, structure, filter media grade, frame material, logo and packaging. We have developed more than 1000 filtration solutions, and we can adapt the catalytic mesh to your existing frame or drawing. Please provide your specifications for a proposal.
Send us your device or vehicle model, required size or drawing, airflow data, operating conditions and expected quantity via our contact page. Our team will review the requirements and provide a sample and quotation accordingly. We aim to respond with a suitable configuration promptly.
MOQ depends on the specific configuration and customisation requirements. Please share your project details and we will confirm the MOQ for your application. For standard sizes, lower quantities may be possible.
Lead time varies with order quantity, customisation level and current production schedule. Our automated lines support a monthly capacity of millions of pieces, which helps maintain stable delivery. We will confirm a specific lead time once your requirements are reviewed.
The recommended service life is 12 to 36 months, depending on the actual pollutant concentration in the operating environment. In spaces with higher formaldehyde loading, replacement should be at the lower end of that range. Please share your operating conditions for a more precise recommendation, and contact us for a tailored assessment.
