Passenger Vehicles
Clean intake air and cabin comfort start with the filter media. Huarui supplies OEM-grade pleated media that keeps passenger car engines breathing and cabins fresh across the full service interval.
Industry Pain Points
Conventional air filter paper suffers from low filtration efficiency, poor precision, low dust-holding capacity and short service life.
Resin swelling under hot and humid conditions clogs micro-pores, cutting air permeability by 15%–30%.
Particle accumulation raises pressure drop quickly, shortening the effective life of the filter element.
Ordinary media show low permeability, weak burst strength and poor water resistance in rainy seasons.
