Kelan Core uses custom-grade Toray filter paper, highlighting its superior product strength.

Toray is a globally renowned materials company, founded in Japan in 1926. Its business spans fields such as fibers, high-performance chemicals, carbon fiber composites, environmental engineering, and life sciences. It has achieved remarkable results in materials innovation and production, holding a leading global position in carbon fiber and possessing numerous core technologies and patents.

Kelan Core's customized Toray H13 grade composite filter paper has the following advantages:

- Extremely high filtration efficiency: According to relevant standards, the filtration efficiency for particles ≥0.3μm is ≥99.97%, which can effectively remove tiny dust, bacteria, viruses and other particles from the air, providing deep purification for indoor air, protecting users' respiratory health, and can be widely used in places with strict air quality requirements, such as medical operating rooms.

- Low air resistance and low energy consumption: Despite its ultra-high filtration efficiency, Toray has optimized the filter paper fiber material and structure through advanced processes, resulting in low air resistance. During air purification equipment operation, it does not excessively obstruct airflow, thereby reducing fan energy consumption, saving operating costs, and aligning with the concept of energy conservation and environmental protection.

- High dust holding capacity: The fibers in the filter paper have good rigidity and toughness, which can withstand the accumulation of a large number of particles without deformation, so that the filter can maintain efficient filtration for a long time, reduce the frequency of replacement, and improve the convenience and economy of use.

- Brand Quality Assurance: Toray is renowned for its rigorous production processes and quality control system, boasting an excellent brand reputation. Kelan Core uses Toray's H13 grade composite filter paper, ensuring stable and reliable product quality and giving consumers peace of mind.
