For Proton Iriz, Saga VVT and Persona VVT Cabin Filter Blue with Bracket PW990493B, this is a cabin air filtration component designed to keep the vehicle interior air clean and comfortable by filtering dust, pollen, smoke particles and fine airborne contaminants before they enter the cabin through the air-conditioning system. This blue cabin filter comes with an integrated bracket for proper fitment and easier installation inside the HVAC system. The filter media provides effective dust and particle trapping while maintaining smooth airflow, helping the air-conditioning system operate efficiently without unnecessary restriction. The bracket ensures stable positioning inside the housing, preventing air bypass and maintaining consistent filtration performance. Specification includes part number PW990493B, compatible with Proton Iriz, Saga VVT and Persona VVT models. It is designed for direct replacement with OEM-standard sizing, suitable for Proton compact hatchback and sedan platforms widely used for daily commuting and urban driving conditions. Using a clean cabin air filter helps improve cabin air freshness, reduce dust inside the vehicle, enhance air-conditioning efficiency and maintain a healthier driving environment. It also helps reduce unpleasant odors, prevents blower motor strain and supports smoother airflow from the air-conditioning system. Regular replacement is important because a clogged filter can reduce cooling performance and allow dust buildup inside the cabin over time. Return and warranty are subject to proper installation and normal usage conditions. Any damage caused by incorrect fitting or overdue replacement will not be covered. Always inspect and replace the cabin air filter during scheduled maintenance to maintain optimal comfort and air quality. For workshop service, we recommend replacing the cabin air filter regularly to keep your Proton interior air clean, fresh and comfortable.
