ZJNF Custom Dimension Efficiency Air Filter Element For Air Purifier

‌Air Filter Element‌
The air filter element is a critical component of the engine's intake system, primarily designed to filter out dust, sand, and other impurities from the air, protecting internal engine parts from wear. Based on filtration accuracy and application, they can be categorized into primary, medium, and high-efficiency types, with common materials including non-woven fabric, activated carbon, and HEPA.

‌Main Types and Features‌

1. ‌Standard Paper Type‌
   Made of non-woven fabric or filter paper, this type is cost-effective and suitable for environments with lower air quality requirements, but it offers limited filtration efficiency for PM2.5 and formaldehyde.

2. ‌Activated Carbon Filter‌
   Features an additional activated carbon layer on the fiber base, effectively adsorbing odors and harmful gases, making it ideal for industrial areas or high-traffic zones.

3. ‌HEPA Filter‌
   A high-efficiency particulate air filter that captures 99.97% of particles as small as 0.3 microns, recommended for allergy sufferers or highly polluted environments.

Replacement Cycle‌

• • ‌General Recommendation‌: Replace every 10,000–20,000 km (6,000–12,000 miles in dusty areas).
  • ‌DIY Inspection‌: Open the engine bay and inspect the filter for dust buildup; replace if clogged.
  • ‌Caution‌: Avoid cleaning with compressed air, as it may damage the filtration layer.
