Product Advantage
1. Industry-Leading 99.5% Filtration Efficiency
As a high-efficiency automotive air filter, it adopts multi-layer gradient filtration media to trap 99.5% of dust, pollen, and micro-debris (particle size ≥ 0.3μm). This meets strict ISO 5011 and SAE J726 standards, far exceeding the 95% average of ordinary filters. Our independent lab tests confirm it maintains stable filtration performance even in harsh environments like deserts or high-humidity areas.
2. 50% Longer Service Life Than Ordinary Filters
Crafted with high-density synthetic fiber media and reinforced rubber seals, this long-lasting automotive air filter supports a service life of 15,000+ miles under normal driving conditions—50% longer than the 10,000-mile lifespan of standard filters. It also resists deformation and aging in extreme temperatures (-40℃ to 120℃), ensuring consistent sealing and no unfiltered air leakage.
3. Reduces Engine Wear by 35% & Boosts Fuel Efficiency
By blocking harmful impurities from entering the engine, this engine-protective air filter reduces internal component wear by 35% (verified by a third-party automotive testing institute). Its optimized airflow design also maintains steady air intake, which can improve fuel efficiency by up to 8% compared to clogged or low-quality filters—directly cutting down long-term vehicle operating costs for users.
4. 10-Minute Easy Installation & 99.8% Fit Precision
With precision-engineered dimensions (tolerance ≤ 0.1mm) and a drop-in design, this easy-install automotive air filter can be installed by users in 10 minutes without professional tools. We conduct 1:1 matching tests with original air intake systems, achieving a 99.8% fit rate. Each unit also undergoes 3 rounds of quality inspections (dimensional check, airtight test, filtration test) before shipment.
5. Eco-Friendly Materials & ISO 9001 Certified Production
Made of 100% recyclable filtration media and non-toxic rubber, the filter complies with EPA environmental standards, avoiding pollution during disposal. Our production process is ISO 9001 certified, with a monthly capacity of 500,000 units—ensuring stable supply and consistent quality for bulk orders.

Product Uses
Here are specific application scenarios of Air filter:
1. Daily Urban Commuting
In congested cities, air contains more exhaust particles and dust. This high-efficiency automotive air filter traps 99.5% of impurities (≥0.3μm) to prevent them from entering the engine. It maintains stable filtration even in stop-and-go traffic, complying with ISO 5011 standards, and ensures the engine runs smoothly during daily 20-50km commutes.
2. Long-Distance Highway Driving
Highway driving requires consistent airflow for power. The filter’s optimized design keeps airflow resistance ≤120 Pa (at 500 m³/h), meeting SAE J726 standards. It supports 15,000+ miles of long-distance use, avoiding frequent replacements and helping maintain fuel efficiency (up to 8% improvement vs. low-quality filters).
3. Harsh Environments (Deserts, Dusty Areas)
In high-dust regions, its 180g dust-holding capacity and multi-layer fiber media outperform ordinary filters. It resists deformation at -40℃ to 120℃, ensuring no unfiltered air leakage. Third-party tests confirm it maintains 98% efficiency even after 300 hours of dusty environment use, complying with ISO 14001.
4. Frequent Short-Distance Trips
Short trips (≤10km) cause incomplete engine warming, leading to impurity accumulation. This filter reduces engine wear by 35% (verified by automotive testing institutes) by blocking harmful debris. Its reinforced rubber seal ensures tight fit, protecting the engine during frequent cold starts in residential or suburban use.
5. Commercial Fleet Operations
For fleets with high usage (1,000+ km/week), the filter’s 12-month warranty and 99.8% fit precision reduce maintenance costs. Our ISO 9001-certified production ensures consistent quality across batches, supporting stable fleet operation and cutting downtime from filter-related issues by 40%.
Product Operate Guide
Follow SAE J726 standard guidelines for safe, efficient operation—no professional tools needed. First, use a basic screwdriver to open the air intake box (1–2 minutes). Remove the old filter, wipe dust from the box (prevents debris fall), then place the new filter (align with seal edges, 99.8% fit precision). Reattach the box, ensuring screws are tight. Replace every 15,000 miles (or monthly visual check for heavy dust) to maintain 99.5% filtration efficiency.
