Jyntrel's fresh air HVAC HEPA filter is a composite filter that combines polypropylene (PP) media with modified activated carbon to capture fine particulate matter and adsorb odours in one layer. It is designed for fresh air systems, fresh air air-conditioners, and central HVAC equipment, serving residential and commercial ventilation applications. The filter is available in efficiency classes from F7 to H13 and can be fully customised to match specific airflow paths and equipment geometries.
This filter is engineered for the air path of fresh air systems, where outdoor air is drawn through the filter before being supplied to the indoor environment. The operating conditions that matter most are airflow rate, face velocity, and the presence of gaseous contaminants. The composite PP media is pleated to provide a large filtration area within a compact frame, which helps maintain a low pressure drop at typical HVAC velocities. The activated carbon layer is positioned to adsorb odours and volatile organic compounds (VOCs) as the air passes through, without adding significant resistance.
In a fresh air system, the filter typically operates continuously, so the pressure drop and dust-holding capacity directly influence energy consumption and maintenance intervals. Jyntrel tests each filter for airflow resistance and filtration efficiency before shipment, so you can specify the grade that balances efficiency with the available fan pressure. The filter can be supplied in flat panel, V-bank, or composite configurations to suit different duct layouts and space constraints.
The core performance of this filter lies in its dual-action media: the polypropylene layer captures fine particles such as PM2.5 and pollen, while the high-iodine-value activated carbon layer adsorbs formaldehyde, TVOC, and other odours. Efficiency grades cover F7, F8, and F9 (medium efficiency) through H11, H12, and H13 (HEPA), allowing selection based on the required indoor air quality and the capability of the air handling unit. For H11 to H13 grades, filtration efficiency for 0.3 μm particles ranges from 95% to 99.97%, as verified by our testing.
The activated carbon is modified to enhance its adsorption capacity for gaseous pollutants, making the filter suitable for areas with traffic exhaust, industrial emissions, or seasonal pollen. Because the carbon layer is integrated into the filter, it eliminates the need for a separate odour filter in many applications, simplifying the system and reducing installation space. The filter is not intended for medical use and is not a substitute for source control of pollutants.
To recommend the right filter for your application, we need specific information about your system and requirements. Please provide the following data:
With this information, we can select the appropriate media grade, pleat density, and frame type, and provide a quotation. Customisation options include size, frame material (paper, aluminium, or plastic), efficiency grade, pleat count and height, addition of activated carbon or other functional layers, and packaging with your logo.

We operate multiple automated production lines with a monthly capacity of several million pieces, ensuring supply stability for large orders.
Quality is controlled through IQC, IPQC, and OQC processes, and our in-house laboratory is CNAS-accredited and can issue test reports for filtration efficiency, dust-holding capacity, and airflow resistance. We are certified to ISO 9001, ISO 14001, and ISO 45001, and obtained IATF 16949 certification in 2024. Products comply with REACH and RoHS environmental regulations, and we can provide compliance documents. Our OEM/ODM services cover size, structure, filter grade, frame material, logo, and packaging, with over 1,000 filtration solutions developed to date.
To receive a tailored solution for your fresh air system, please share your device or vehicle model, required size or drawing, airflow rate, operating conditions, and estimated quantity. Our engineering team will review your data and respond with a recommendation and quotation. Contact us to discuss your filtration requirements.
The filter is available in grades from F7 to H13, with H11 to H13 providing 95% to 99.97% filtration efficiency for 0.3 μm particles. The appropriate grade depends on your air quality target and system pressure. Please share your requirements for a recommendation.
Yes, the pleated composite PP media is designed to maintain a low pressure drop at typical HVAC face velocities. However, for high-velocity applications, we recommend reviewing the pressure drop curve with our engineers to ensure the filter meets your system's airflow requirements.
We need the design airflow rate (m³/h) and the dimensions of the filter slot. Additionally, information on the operating environment, such as temperature and humidity, helps us select the right media and frame. Provide these details via our contact form for an accurate quote.
Yes, we offer full customisation of size, frame material (paper, aluminium, or plastic), efficiency grade, pleat count and height, and the addition of activated carbon or other functional layers. We also customise labels and packaging. With over 1,000 filtration solutions developed, we can match or develop a filter for your model.
Standard specifications typically have an MOQ of 500–1,000 pieces, while customised filters generally require 1,000–3,000 pieces. Lead time is 15–25 days for standard products and 30–45 days for customised items, including mould making. Contact us for a precise quote based on your requirements.
Yes, we provide samples for testing. Standard specification samples are free, with the customer covering international courier costs. Customised samples incur a sample fee, which is refundable upon bulk order. Our R&D team supports the entire process from sample evaluation to mass production.
In typical residential environments, we recommend replacement every 6–12 months, depending on air quality and operating hours. The actual life depends on dust loading and odour levels. Our CNAS-accredited lab can test dust-holding capacity and pressure drop to help you establish a replacement schedule.
Yes, this filter already combines PP media for particle removal and activated carbon for odour and VOC adsorption. We also offer additional functional layers such as formaldehyde removal or antibacterial treatment. Share your specific pollutant targets and we can tailor a multi-layer solution for your application.
