The Jyntrel fresh air / fresh air conditioning odor removal filter is a composite filter combining polypropylene (PP) media with modified activated carbon. It captures fine particulate matter such as PM2.5 and pollen while adsorbing formaldehyde, TVOC, and other odorous gases. It is designed for residential wall-mounted fresh air units, cabinet fresh air conditioners, and central HVAC systems in homes and commercial buildings. Jyntrel manufactures this filter with customizable efficiency from F7 to H13 and full OEM/ODM support.
In a fresh air system, outdoor air is drawn through the filter before entering the ductwork or the conditioned space. The filter therefore sees continuous airflow with varying velocity depending on the fan speed and system design. The composite PP layer provides mechanical filtration of particles, while the activated carbon layer adsorbs gaseous contaminants as the air passes through. The filter is typically installed in a frame or cassette that holds it perpendicular to the airflow, ensuring even loading across the media face.
Air velocity affects both pressure drop and capture efficiency. At higher velocities, the filter may exhibit increased resistance, which can influence fan energy consumption. Jyntrel tests each filter design for airflow resistance and efficiency to ensure stable performance across the intended operating range. The filter is not intended for use in environments with excessive moisture or where the air contains solvents that could degrade the activated carbon.
The filter is available in efficiency classes from F7/F8/F9 (medium efficiency) up to H11/H12/H13 (HEPA) for particulate removal. The activated carbon layer uses high iodine value carbon to provide deep adsorption of formaldehyde, TVOC, ammonia, and hydrogen sulfide. This dual-function design allows a single filter to address both particulate and gaseous contaminants, simplifying system design and maintenance.
Performance data is verified in Jyntrel's CNAS-accredited laboratory, where filters undergo rigorous testing for airflow resistance and filtration efficiency before shipment. The filter media and activated carbon are selected to meet REACH and RoHS requirements, and compliance documentation is available upon request.
To recommend the appropriate filter, Jyntrel needs specific information about your system and requirements. Please provide the following:
With these details, Jyntrel can propose a filter configuration that balances efficiency, pressure drop, and service life. Customisation options include flat panel, V-bank, or composite designs, as well as choice of frame material and activated carbon type. Jyntrel has developed over 1,000 filtration solutions and can adapt existing designs or create new tooling as needed.

This filter is used in residential wall-mounted fresh air units, where it helps maintain indoor air quality by removing particles and odors from incoming outdoor air. In cabinet fresh air conditioners, it protects the heat exchanger and improves the quality of conditioned air. For residential and commercial central fresh air systems, the filter can be specified in various efficiency grades to meet different indoor air quality targets. The dual-function design is particularly beneficial in urban areas where outdoor air contains both particulate matter and gaseous pollutants.
Jyntrel operates multiple automated production lines capable of producing millions of filters per month, ensuring supply stability for large-scale projects. With over 20 years of experience in filtration and more than two decades of exports to Europe, the United States, Japan, and South Korea, Jyntrel understands the quality and documentation requirements of international markets.
The 50,000 m² manufacturing plant includes six cleanrooms totalling 20,000 m², where filter production is carried out under controlled conditions. Jyntrel's 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 airflow resistance. The company holds ISO 9001, ISO 14001, and ISO 45001 certifications, and achieved IATF 16949 certification in 2024. Quality control follows IQC, IPQC, and OQC procedures throughout the production process.
To receive a tailored quotation or technical recommendation, please contact Jyntrel with your device or vehicle model, filter size or drawing, airflow or water flow rate, operating conditions, and estimated quantity. Our team will review your requirements and respond promptly. Contact us to discuss your application.
Yes, the filter is designed to operate across a range of air velocities typically found in fresh air systems. However, higher velocities may increase pressure drop, so we recommend providing your expected airflow rate to ensure optimal performance. Jyntrel tests each design for airflow resistance and efficiency.
We need the airflow rate (m³/h) and the expected face velocity at the filter. Additionally, the system's maximum allowable pressure drop and the required filtration efficiency help us select the right media and carbon loading. Please share these details for an accurate quotation.
The filter is available in particulate efficiency grades from F7 to H13, corresponding to medium to HEPA efficiency. The activated carbon layer adsorbs formaldehyde, TVOC, and other odorous gases. Efficiency is verified in Jyntrel's CNAS-accredited laboratory.
Yes, Jyntrel offers full OEM/ODM customisation, including dimensions, shape (flat, V-bank, composite), frame material, activated carbon type, and packaging. We can develop tooling based on your unit's requirements. Please provide a drawing or sample for evaluation.
Standard models typically have an MOQ of 500–1,000 pieces, while customised versions generally require 1,000–2,000 pieces. Lead time for stock items is 7–10 days; custom orders take about 25–35 days for the first order and 15–25 days for repeat orders. Sample orders can be accommodated flexibly.
Yes, we welcome sample requests for evaluation. Standard samples are free, with the customer covering international shipping costs. Custom samples may incur a fee depending on tooling complexity, which can be refunded upon bulk order. CNAS test reports are also available to support your technical review.
Under normal operating conditions (PM2.5 around 35 µg/m³, 8–12 hours daily use), we recommend replacement every 6–12 months. Actual life depends on local air quality, usage patterns, and contaminant levels. Jyntrel can provide customised dust holding capacity and carbon iodine value options to optimise replacement intervals.
The filter is produced under ISO 9001 and IATF 16949 quality management systems. Materials comply with REACH and RoHS requirements, and compliance documents are available. Jyntrel's CNAS-accredited lab provides test reports for efficiency and resistance.
