Top 10 sub-hepa filter Suppliers in China 2025

Introduction to sub - hepa filter

Sub - HEPA filters are an important category of air filters. They are designed to capture a significant amount of airborne particles, although their efficiency is lower than that of High - Efficiency Particulate Air (HEPA) filters. Sub - HEPA filters typically have a particle capture efficiency in the range of 80% - 99% for particles larger than 0.3 microns. These filters are widely used in various applications where high - level air purification is not strictly required but a certain degree of particle removal is necessary. Common applications include general ventilation systems in commercial buildings, some industrial processes, and certain types of air - handling units. They offer a cost - effective solution for improving indoor air quality and protecting equipment from particulate contamination.
