The Oltaven automotive cabin air filter with activated carbon is a finished filter that combines high-efficiency HEPA media with high-iodine coconut shell activated carbon to capture PM2.5 particles and adsorb odors, ammonia, sulfides and VOCs from exhaust fumes. It is designed for passenger cars, buses, heavy trucks and construction machinery, and for brands and distributors that need custom-fit cabin filters. Oltaven manufactures the complete filter—not just the media—so pleating, framing and sealing are controlled to deliver consistent efficiency, low resistance and high dust holding capacity.
The media is only the starting point. To turn it into a cabin air filter, we pleat the HEPA layer, combine it with a carbon layer, and seal it into a frame. Each step affects how the filter performs in the vehicle: pleat height and count set the surface area, the frame holds the pleats in place, and the seal prevents air from bypassing the media. Oltaven sells finished filters, so we control these steps in-house and can adjust them to match your original equipment requirements.
Three factors determine the finished filter’s efficiency, resistance and capacity. First, media choice: our HEPA media captures fine particles, while the high-iodine coconut shell carbon targets odors and gases. Second, forming: pleating increases the media area, which lowers air resistance and raises dust holding capacity; the pleat count and depth are balanced for each application. Third, framing and sealing: a rigid frame and a reliable seal keep the media in the airflow path, preventing bypass and maintaining efficiency over the service life. Because we produce the complete filter, we can tune these variables to meet your target resistance and capacity.
This cabin air filter is used in the air conditioning and ventilation systems of passenger cars (sedans, SUVs, MPVs), commercial buses, heavy trucks and construction machinery. It helps reduce PM2.5, dust and odors inside the cabin, supporting a more comfortable environment for drivers and passengers.

To receive a quotation or discuss a custom cabin filter, please provide your device/vehicle model, required size or drawing, airflow or water flow (if applicable), operating conditions, and estimated quantity. Visit our contact page to start the conversation. We welcome OEM and ODM partnerships and will respond promptly.
Resistance depends on media choice, pleat count and depth, and how well the frame and seal prevent bypass. Our finished filters are engineered with pleat patterns that balance surface area and airflow, achieving low resistance without sacrificing efficiency. Because we control forming and sealing, we can tune resistance to match your system.
An OEM project starts with your requirements: vehicle model, size or drawing, airflow, operating conditions and quantity. We then propose a design and provide samples for validation. After approval, we proceed to production with full quality control.
Our cabin air filter uses a multi-layer composite structure with activated carbon, achieving over 95% filtration efficiency for PM2.5 particles. It also effectively adsorbs odors, formaldehyde, benzene series and VOCs. Efficiency is validated in our CNAS-accredited laboratory.
Yes, we support 100% OEM/ODM customization for all vehicle models. We can customize any length, width, thickness and pleat count according to your original equipment air duct requirements. Provide your vehicle model or sample dimensions for precise matching.
Standard models have an MOQ of 1,000–2,000 pieces, while custom models typically require 3,000–5,000 pieces depending on tooling and media. Bulk orders usually ship in 25–35 days, and urgent orders can be expedited upon discussion.
Under standard conditions, we recommend replacement every 6–12 months or 15,000–20,000 km, depending on local air quality. In heavy smog or dust areas, shorter intervals are advised. We can adjust media weight and carbon load to extend service life for your market.
Yes, we offer free samples of existing specifications within 3–5 working days (freight collect). Custom samples are delivered within 7–15 working days after drawing confirmation. Samples come with relevant test data for your evaluation.
Our manufacturing is certified to IATF 16949 (2024) and ISO 9001, ISO 14001, ISO 45001. Products comply with REACH and RoHS, and we can provide compliance documents. Testing is performed in our CNAS-accredited laboratory. For partnership inquiries, please contact us.
