The Zanxis flat panel HEPA activated carbon composite filter is a dual-layer air filter that removes fine particulate matter and adsorbs odors and gaseous pollutants in a single low-profile panel. It is designed for residential and commercial air purifiers, desktop purifiers, humidifier-purifier combos, dehumidifiers, and compatible with household air conditioners. Zanxis manufactures this filter with PP, PP+PET, or PTFE media and honeycomb or modified activated carbon, offering full OEM customisation to match your device cavity.

Because performance is directly tied to the chosen media and the fan characteristics of your device, we recommend confirming several parameters before finalising a specification. First, the dust removal efficiency grade and target CADR value—these must be matched to your purifier's airflow and pressure drop. Second, the type and amount of activated carbon, as this determines the odour and formaldehyde removal capacity and the replacement interval. Third, the exact panel dimensions and frame sealing requirements, since the filter must fit your device cavity without bypass. Fourth, the expected operating conditions (humidity, temperature, pollutant load) so we can recommend the most suitable media. Finally, the required certifications and test reports for your market. Confirming these values early avoids rework and ensures the sample you receive reflects the final production filter.
We follow a structured sample validation process so you can verify performance before mass production:
The Zanxis flat panel filter uses a dual-layer composite construction: a HEPA layer made from PP, PP+PET, or PTFE media for fine particle capture, and an activated carbon layer using honeycomb activated carbon or modified formaldehyde-removal carbon granules for gas-phase adsorption. The MAX flat design minimises thickness, allowing device designers to save space without sacrificing filtration performance. The ultra-low airflow resistance helps maintain a quiet operation and energy efficiency. The filter can be customised to any length, width, and thickness, with a choice of frame materials and sealing to suit your device. Typical applications include portable air purifiers, desktop units, humidifier-purifier combos, and dehumidifiers. Because the filter is custom-made to your specifications, installation and replacement are straightforward—simply slide the panel into the designated slot.
Quality is verified at every stage. Our in-house laboratory is accredited by CNAS (China National Accreditation Service for Conformity Assessment), and we can issue test reports covering filtration efficiency, dust holding capacity, and airflow resistance. The production facility covers 50,000 m², including six clean rooms totalling 20,000 m². Zanxis is certified to IATF 16949 (achieved in 2024) and holds ISO 9001, ISO 14001, and ISO 45001 certifications. Products comply with REACH and RoHS regulations, and we can provide compliance documentation. With over 20 years of experience in filtration research and manufacturing, we have exported to Europe, the US, Japan, and South Korea for more than two decades. Our quality control follows IQC, IPQC, and OQC processes, and we operate multiple automated production lines with a monthly capacity of millions of pieces. We support OEM/ODM customisation of size, structure, media grade, frame material, logo, and packaging, and have developed over 1,000 filtration solutions. Our address is Zhongshan, Guangdong, China.
To receive samples and test reports, please provide the following information: your device or vehicle model (if applicable), required size or a drawing, target airflow or water flow (if relevant), operating conditions (temperature, humidity, pollutant type), and estimated quantity. Our engineers will review your requirements and respond with a proposal and sample timeline. Contact us to start the verification process.
Yes, we can provide test reports from our CNAS-accredited laboratory. These reports cover filtration efficiency, dust holding capacity, and airflow resistance for the specific sample or production batch. For activated carbon filters, we also test odour removal performance and decay indicators.
Custom samples are typically fabricated within 7–10 days after specification confirmation. Laboratory testing adds a few days, and you will receive the test report with your samples. Overall validation time depends on your own evaluation period.
The filter uses a dual-layer composite structure: a HEPA layer that can achieve ≥99.97% filtration efficiency for 0.3μm particles (H13 grade, upgradeable to H14 upon request), effectively capturing PM2.5, pollen, dust mites, and bacteria; and an activated carbon layer using high-iodine coconut shell or coal-based carbon with excellent adsorption capacity for formaldehyde, TVOC, and odours. One filter addresses both particulate and gaseous pollutants, making it suitable for household air conditioners and fresh air systems.
Under normal household use (8–10 hours per day), the recommended service life is 6–12 months, depending on local air quality and usage frequency. The filter is compatible with mainstream wall-mounted, cabinet, and central air conditioners. We customise dimensions based on your model or drawing, with thickness options from 5 mm to 50 mm and frame choices including paper, plastic (ABS/PP), or aluminium.
Zanxis is certified to ISO 9001, ISO 14001, and ISO 45001, and the product complies with European BSC1, US EPA, NSF, and SOP standards. In 2024, we also obtained IATF 16949 (automotive) and medical device GMP certification. Our products are regularly exported to Europe, the US, Japan, and South Korea, and we can provide CE, RoHS, and REACH test reports to support your market access.
Yes, we offer full OEM/ODM services. Leveraging over 20 years of R&D and a library of more than 1,000 filtration solutions, we customise filter dimensions, media specifications (HEPA grade, carbon weight), frame structure, and colour. Packaging options include neutral packaging, customer-branded colour boxes, custom labels, multilingual manuals, and专属 barcodes to help brands and traders quickly build their product lines.
Our 50,000 m² facility includes six clean rooms totalling 20,000 m², ensuring a contamination-free production environment. Our CNAS-accredited laboratory is equipped with particle counters, wind tunnels, and formaldehyde/VOC detectors to test filtration efficiency, resistance, dust holding, and adsorption performance for every batch of raw materials and finished products. We perform 100% visual inspection and AQL 1.0 sampling before shipment to ensure consistency and stability.
Standard specifications typically have an MOQ of 500–1,000 pieces; custom specifications are negotiated based on complexity, generally 2,000–3,000 pieces. Regular lead time is 25–35 days after order confirmation, and samples can be shipped within 7–10 days. We offer free small samples for performance testing and market validation; custom sample fees are refundable upon formal order, helping you verify products with low risk.
