This Fresh Air HVAC HEPA Filter from Zanxis is a composite filter combining polypropylene (PP) media with modified activated carbon. It removes fine particulate matter such as PM2.5 and pollen while adsorbing formaldehyde, TVOC, and other odours. It is designed for residential wall-mounted fresh air units, cabinet fresh air air conditioners, and central HVAC systems. Zanxis manufactures it in Zhongshan, Guangdong, China, and supplies it with options for efficiency class, dimensions, and frame type. Use the tables and workflow below to confirm the values that matter for your application.

Before selecting a filter, confirm the efficiency grade and pressure drop at your design airflow. The table above lists F7 to H13 grades, but the actual pressure drop depends on pleat count, media area, and face velocity. Ask for the resistance curve at your operating airflow so you can verify fan capacity and energy use.
Confirm the activated carbon grade and iodine value if odour removal is critical. The media is described as modified odour-removal activated carbon; higher iodine value typically means greater adsorption capacity, but we recommend reviewing the test report for the specific carbon lot. Also verify the dust holding capacity and recommended replacement interval for your environment. For residential use, 6–12 months is typical, but actual life depends on particulate loading and runtime.
Finally, confirm the mechanical fit: frame dimensions, pleat direction, and any gasket or mounting interface must match your unit. Provide a drawing or sample of the existing filter to avoid dimensional mismatch.
The filter uses composite PP media, which provides mechanical strength and fine particle capture without the shedding associated with some glass-fibre media. The activated carbon layer is integrated into the filter, so you get particle and odour removal in a single component. This simplifies replacement and reduces the number of parts in the unit.
Zanxis offers flat, V-bank pleated, and composite configurations. The V-bank design increases media area within a given face dimension, which can lower pressure drop or increase dust holding capacity at the same airflow. Composite designs may combine a pre-filter layer with HEPA media and carbon to extend service life.
Typical applications include wall-mounted fresh air machines, cabinet fresh air air conditioners, and central HVAC systems. The filter is intended for dry operation; avoid contact with water or excessive humidity unless the unit design allows it. Follow the equipment manufacturer’s instructions for replacement and disposal.
Zanxis operates a CNAS-accredited laboratory that issues test reports for filtration efficiency, dust holding capacity, and resistance. These reports are generated for the specific product and lot, so you can verify the values that matter for your design.
Production is governed by IQC, IPQC, and OQC processes. Incoming materials are inspected, in-process checks monitor pleating and assembly, and outgoing inspection verifies final dimensions and performance before shipment. The plant covers 50,000 m², including six clean workshops totalling 20,000 m². Zanxis holds IATF 16949 certification (obtained in 2024) and ISO 9001, ISO 14001, and ISO 45001 system certifications. Products comply with REACH and RoHS requirements, and compliance documents are available on request.
With more than 20 years of filtration experience and over 1,000 filtration solutions developed, Zanxis supports OEM/ODM projects including size, structure, media grade, frame material, logo, and packaging customisation. Automated production lines support monthly output in the millions of pieces.
To request samples and test reports, please provide: your device or vehicle model; required size or a drawing; airflow or water flow (as applicable); operating conditions such as temperature, humidity, and pollutant load; and estimated quantity. This information allows us to recommend the correct efficiency grade and carbon option and to prepare an accurate quotation. Contact us via our contact page to start the process.
Yes. Zanxis operates a CNAS-accredited laboratory that issues test reports for filtration efficiency, dust holding capacity, and resistance. Reports are specific to the product and lot, so you can verify the values for your application. Request reports together with your sample inquiry.
Standard samples from existing tooling can be dispatched quickly, typically within a few days. Custom samples built to your drawing usually require 2–4 weeks for production and testing. Validation time on your side depends on your test setup; we recommend planning for at least one week for fit and performance checks.
The filter is available in F7, F8, and F9 medium-efficiency grades, and H11, H12, and H13 HEPA grades. The choice depends on your target particle removal and allowable pressure drop. Provide your airflow and efficiency target, and we will confirm the suitable grade.
Yes. Zanxis supports full customisation of dimensions, frame material, pleat count, and media grade, as well as flat, V-bank, and composite configurations. Provide a drawing or sample of your current filter to ensure a precise fit. Logo and packaging customisation are also available.
Standard sizes typically have an MOQ of 500–1,000 pieces. Customised filters generally require 1,000–3,000 pieces, depending on specification and packaging. MOQ is confirmed with your quotation.
Standard products ship in 15–25 days after order confirmation. Customised products, including tooling, typically require 30–45 days. Lead times are confirmed at order placement and depend on current capacity.
In typical residential use, Zanxis recommends replacement every 6–12 months. Actual life depends on outdoor air quality, runtime, and particulate loading. Monitor pressure drop or follow the equipment manufacturer’s indicator; replace when airflow drops noticeably or odour removal fades.
