Ranveth Fresh Air HVAC HEPA Filter combines composite PP media with a modified activated carbon layer to capture fine particles such as PM2.5 and pollen while adsorbing formaldehyde, TVOC, and odors. It is built for residential wall-mounted fresh air units, cabinet-style fresh air air conditioners, and central HVAC systems. This filter is offered in efficiency classes from F7 to H13 and is fully customizable to fit specific equipment models.
The performance of this filter comes from how its layers work together. A composite polypropylene (PP) medium forms the particle-capture core, while a modified activated carbon layer handles odor and gas-phase pollutants. The PP medium is selected for consistent fiber distribution, which supports stable efficiency and airflow resistance across the filter face. The activated carbon is chosen for high iodine value, giving it a large internal surface area for adsorbing formaldehyde, TVOC, and other odorous compounds.
Layer order and pleat geometry are matched to the target efficiency class and the pressure budget of the host appliance. For lower-resistance applications, a single PP layer may be paired with a thin carbon layer; for higher-efficiency HEPA grades, a denser PP medium is used with a carbon layer that balances adsorption capacity against airflow. This pairing directly affects three outcomes: particle removal efficiency, initial pressure drop, and service life. A well-matched combination maintains efficiency without overloading the fan, and it distributes dust loading more evenly to avoid premature blockage.
Because the carbon layer also adds resistance, the pleat count and pleat height are adjusted so that the filter meets the target HEPA class while staying within the airflow budget of the equipment. This is why Ranveth treats media pairing and layer build as a single design step rather than separate choices.

This filter is designed for air-moving equipment that needs both particle removal and odor control. Typical installations include wall-mounted fresh air units in homes, cabinet-style fresh air air conditioners, and central fresh air systems in residential or commercial buildings. It is also used as a composite cartridge in fresh air machines where HEPA-grade particle filtration and gas-phase adsorption are required in a single filter stage.
Because the filter is built to the equipment maker's drawing, it can be specified for new appliance platforms or as a replacement filter for existing models. The flat panel, V-bank folded, and composite formats cover different space and pressure-drop requirements, so the same media pairing approach can be adapted across a range of air handlers.
To develop a filter that fits your equipment and meets your performance targets, please provide the following information:
With these details, our engineering team can propose a media and layer combination, confirm feasibility, and provide a sample for evaluation. If you have an existing filter to match, a physical sample or clear photos with dimensions will help us replicate fit and performance.
Ranveth makes media decisions based on test data. Our 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. This means the media pairing in your filter is backed by measurable results, not assumptions.
Production takes place in a 50,000 m² manufacturing base that includes six cleanrooms totaling 20,000 m², where filters are assembled in controlled environments to avoid secondary contamination. Our quality management system is certified to ISO 9001, ISO 14001, and ISO 45001, and in 2024 we added IATF 16949 certification for automotive industry quality management.
With more than 20 years of experience in filtration research and manufacturing, we have developed over 1,000 filter solutions and support OEM/ODM customization of size, structure, media grade, frame material, logo, and packaging. Products comply with REACH and RoHS environmental regulations, and we can provide compliance documents for your market access needs. Our location is Zhongshan, Guangdong, China.
To discuss your filter requirements, please send us your device or vehicle model, required size or drawing, target airflow or water flow (if applicable), operating conditions, and estimated quantity. Our team will respond with a tailored proposal, sample availability, and pricing. You can reach us through our contact page. We look forward to supporting your project with a filter that is matched to your equipment and performance goals.
It uses a composite PP (polypropylene) filter paper as the particle-capture medium, paired with a modified activated carbon layer for odor and gas-phase adsorption. This combination allows one filter to address both PM2.5 and odors such as formaldehyde and TVOC. The media are selected to balance efficiency, airflow resistance, and service life.
The filter can be supplied in medium-efficiency grades F7, F8, and F9, as well as HEPA grades H11, H12, and H13. The grade you choose should match the particle removal target and the pressure budget of your equipment. We can help you select the appropriate grade based on your device and operating conditions.
Yes, full customization is available. We can produce flat panel, V-bank folded, and composite formats according to your drawing or sample, and adjust dimensions, pleat count, media grade, and carbon layer to meet your fit and performance requirements. Please provide your device model and dimensions to start the process.
We support sample requests for evaluation. For standard specifications, samples can be provided, and for custom designs, a sample fee may apply depending on complexity. Sample lead times are typically shorter than production lead times, and we will confirm details after reviewing your requirements.
MOQ depends on the specification and whether the filter is standard or custom. Custom filters usually require a higher MOQ to cover setup and production. Please share your target quantity and specifications so we can confirm the MOQ for your case.
Lead time varies with order quantity, customization level, and current production schedule. Standard configurations typically ship within a few weeks after approval, while custom builds may require additional time for tooling and sampling. We will provide a specific lead time with your quotation.
Replacement interval depends on the operating environment, running hours, and contaminant loading. In typical residential use, we recommend checking the filter every 6 to 12 months and replacing it when airflow drops noticeably or odors return. For commercial or high-dust environments, more frequent inspection may be needed.
Yes, our team can recommend a media and layer build based on your equipment, target efficiency, airflow, and operating conditions. Please contact us with your device model, dimensions, and performance requirements, and we will propose a suitable configuration and provide a quote.
