This automotive cabin air filter combines high-efficiency HEPA media with high-iodine-value coconut shell granular activated carbon to capture PM2.5 dust and adsorb exhaust odours in passenger cars, buses, trucks and construction machinery. It is built for vehicle OEMs, Tier 1 suppliers and aftermarket brands that need low airflow resistance and long service life, and it is manufactured by Ranveth in Zhongshan, Guangdong, China.
The filter uses a dual-effect composite structure: a high-precision HEPA filtration layer paired with high-iodine-value coconut shell granular activated carbon. This pairing is the core of the design. The HEPA layer is selected to intercept PM2.5 particles and dust, while the coconut shell carbon layer is targeted at ammonia, sulphides and exhaust VOCs. Because the two media are combined into one composite, the filter addresses both particulate and odour concerns in a single part.
From a materials standpoint, the pairing also governs airflow resistance and service life. The pleated construction is engineered for low operating resistance, which helps maintain HVAC blower performance and reduces load on the air-conditioning system. A high dust-holding capacity means the filter can store more captured dust before resistance rises to the replacement threshold, extending useful life. In practice, the media combination and pleat geometry are balanced so that efficiency, airflow and life are optimised together rather than traded off.

This cabin air filter is designed for the air-conditioning and ventilation systems of passenger cars including sedans, SUVs and MPVs, as well as commercial buses, heavy trucks and construction machinery. In these vehicles, the filter is the barrier between outside air and the cabin, capturing dust and PM2.5 while the carbon layer adsorbs exhaust odours and VOCs that enter through the HVAC intake.
Because the filter is available with full-vehicle-model OEM/ODM customisation, it can be specified for original equipment programs or aftermarket ranges. Dimensions, thickness and pleat count are tailored to the air duct requirements of each vehicle platform, so the same media pairing can be adapted across different cabin sizes and airflow demands. This makes it suitable for fleet operators, distributors and vehicle brands looking to standardise on a single filtration approach.
To quote accurately, we need the following information. Please provide as much as is available for your application.
With these details, we can confirm the media combination, pleat geometry and carbon loading that best match your efficiency, resistance and life targets.
Ranveth is backed by a CNAS-accredited in-house laboratory. This means media choices are test-backed: we can issue test reports for filtration efficiency, dust-holding capacity and resistance, so you can verify performance before committing to volume.
The manufacturing base is a 50,000 m² plant that includes six cleanrooms totalling 20,000 m². We have held IATF 16949 automotive quality management system certification since 2024 and also maintain ISO 9001, ISO 14001 and ISO 45001 systems. Products comply with REACH and RoHS environmental regulations, and we can provide compliance documentation for export markets. With more than 20 years of filtration R&D and manufacturing experience, we have developed over 1,000 filtration solutions and continue to export to Europe, the United States, Japan and South Korea.
