11. FAQ: Professional FAQ on Car Air Filters

Q1: What are the main materials used in quality car air filters?

A1: Leading filters use pleated cellulose (high pore density), synthetic nonwovens for long life, or composite hybrid media for specialty performance. The frames are often polyurethane (PU), ABS, or glass-filled nylon for structural stability and anti-corrosion.

Q2: What is the meaning of "filtration efficiency" and why is ISO 5011 important?

A2: Filtration efficiency (%) measures how well the filter blocks particulates (usually @ 1 or 2 micron size). ISO 5011 describes standardized testing procedures for automotive air filters, ensuring filters meet global performance benchmarks.

Q3: How do I determine when to replace car air filter?

A3: Most automakers suggest replacement every 15,000–30,000km, but this depends on driving environment. High-dust or off-road use, or engine trouble codes (MAF sensor issues), indicate earlier change is beneficial.

Q4: What installation standards or precautions are required?

A4: Ensure correct filter orientation/alignment to housing. Check the gasket seal, avoid overtightening, and never reuse a clogged or damaged filter. Installation should comply with the car manufacturer's guidelines—refer to SAE J726.

Q5: What factors impact car air filter life?

A5: Material quality, air flow surface area (pleat depth/density), environment (dust/pollution), and maintenance intervals. Synthetic or carbon-based filters typically offer longer life than standard cellulose.

Q6: Are aftermarket filters safe for warranty?

A6: If the filter meets OEM and relevant standards (ISO/TS 16949, ISO 5011), warranty is not void. Always select reputable brands and request compliance documentation.

Q7: What certifications should I look for in a premium car air filter?

A7: Check for ISO 9001 (Quality Management), ISO/TS 16949 (Automotive Quality), REACH, and RoHS conformity; these indicate adherence to global reliability and safety standards.
