G4 primary efficiency cotton is a widely used air filter material in cleanrooms and ventilation systems. Among its key performance indicators, dust holding capacity stands out as particularly crucial. This article explores the importance of the dust holding capacity of G4 primary efficiency cotton, offering insights into its performance and versatile applications.

Nuclear wastewater refers to the wastewater generated by nuclear power plants in normal daily activities, mainly including cooling system wastewater, nuclear fuel reprocessing wastewater, auxiliary facility wastewater, etc. Radioactive substances mainly include tritium, uranium, plutonium, thorium, and radium. Since these radioactive wastewater will directly or indirectly affect human health and life, they need to be treated before they can be discharged.

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.
