  • Introduction to MERV Rating

    MERV (Minimum Efficiency Reporting Value) is a standard used to evaluate the efficiency of air filters, measuring their ability to capture particles in the air. The MERV scale ranges from 1 to 16, with higher numbers indicating higher efficiency. MERV 1-4 is suitable for residential and low-demand commercial environments, primarily capturing large particles like dust; MERV 5-8 is used in ordinary homes and offices, removing medium-sized particles like pollen; MERV 9-12 is appropriate for hospitals, laboratories, and other high-demand environments, capturing bacteria, mold, etc.; MERV 13-16 is for clean rooms and high-standard laboratories, removing almost all small particles, including viruses. When selecting the appropriate MERV rating, it's important to balance filtration efficiency and airflow to avoid overburdening the system.

  • Polypropylene (PP) Cartridge Filter Operating Principle

    Polypropylene (PP) Cartridge Filters are widely used in water treatment, air purification, and chemical filtration. Made from thermally welded polypropylene, they effectively remove particles in liquids, such as in pharmaceuticals and beverages, while extending the lifespan of sterilization filters. These filters use physical, fiber, and depth filtration mechanisms to capture larger and smaller impurities, with micron-level filtration precision (as fine as 0.1μm). PP's chemical inertness prevents contamination, making it suitable for varying pH levels. With advantages like high filtration efficiency, long lifespan, chemical resistance, low cost, and ease of maintenance, they are commonly used in water treatment, food and beverage industries, pharmaceuticals, and air filtration systems.
