Founded in 2019 and headquartered in the industrial heart of Changchun, Jilin Province, China, Changchun Tolev Auto Co., Ltd. is a premier manufacturer specializing in high-performance automotive and industrial filtration solutions. With over 7 years of specialized expertise, we have rapidly evolved into a significant global player, serving more than 30 countries across the Middle East, Europe, and North America.
Our state-of-the-art 5,000 sqm production facility features 9 advanced automated production lines, enabling us to deliver precision-engineered filters that meet the rigorous demands of modern engines and industrial systems. We integrate R&D, manufacturing, and global logistics to provide a seamless OEM experience.
The global landscape for Anti-Microbial Air Filters has seen a paradigm shift. No longer limited to high-risk environments like surgical suites, antimicrobial filtration is now a standard requirement for public transport, office buildings, and automotive cabin environments. As concerns over indoor air quality (IAQ) and airborne pathogens grow, the industry is transitioning from simple dust removal to bio-active purification.
The integration of silver ions (Ag+), copper nanoparticles, and organic antimicrobial coatings into synthetic media is the current gold standard, inhibiting 99.9% of bacterial growth.
Global enterprises are shifting toward ESG-compliant filters that offer longer service lives, reducing both waste and operational downtime in heavy machinery and factories.
From the desert dust of the Middle East requiring high-capacity filters to the humid climates of Southeast Asia demanding mold-resistant antimicrobial layers.
Utilizing 9 fully automated lines, we achieve an annual output of 8 million filters. This scalability ensures we can support large-scale fleet operators and industrial distributors without compromise.
Every filter undergoes over 12 rigorous quality checks. We are compliant with ISO 5011, CE efficiency standards, and pressure resistance validations, ensuring performance under extreme stress.
Our dedicated R&D team can transform your technical drawings into physical prototypes in just 7 days, accelerating your time-to-market significantly.
Through vertical integration—controlling our own synthetic media and steel casings—we offer high-tier filtration at 15-20% lower cost than competitors.
