Air filters play a vital role in our daily lives, effectively removing harmful substances like dust, bacteria, and viruses from the air to safeguard our health. Based on different filtration media and application scenarios, air filters can be categorized into multiple types. This article introduces several common air filter types and their respective applications.

1. Classification by Filter Media

Based on filter media, air filters can be categorized into coarse-efficiency filters, medium-efficiency filters, and high-efficiency filters.

(1) Coarse-efficiency filters primarily remove larger dust particles and impurities. They are suitable for installation at the inlet of HVAC systems to prevent large particles from entering and compromising system performance.

(2) Medium-efficiency filters target medium-sized dust particles and impurities. They are typically placed within HVAC systems to further purify the air.

(3) High-efficiency filters are primarily used in high-precision environments such as operating rooms and laboratories. They effectively remove minute dust particles, bacteria, viruses, and other harmful substances, ensuring indoor air cleanliness.

2. Classification by Application Setting

Based on application setting, air filters can be categorized into commercial filters, industrial filters, and residential filters.

(1) Commercial filters are suitable for shopping malls, offices, hotels, and other commercial spaces. They effectively remove harmful substances like dust, bacteria, and viruses from the air, safeguarding people's health.

(2) Industrial filters are designed for various industrial production settings, such as machinery manufacturing, chemical plants, electronics factories, and pharmaceutical facilities. They meet high-precision, high-efficiency air purification requirements.

(3) Residential filters primarily serve home environments like bedrooms and living rooms, eliminating airborne particulates, odors, and other contaminants to safeguard household members' health.

3. Additional Classification Methods

Beyond the above categories, air filters may also be classified based on structural design, filter media, or operating environments. Examples include:

- Structural types: bag filters, panel filters, liquid-trough filters, pleated filters, etc. Filtration materials like activated carbon, glass fiber, and melt-blown fabric; and filters designed for specific environments such as industrial cleanrooms, hospital operating rooms, and electronics manufacturing facilities. These classifications provide a comprehensive understanding of air filter types, enabling selection based on actual requirements.

Air filters play a vital role in daily life by effectively removing airborne contaminants and safeguarding health. Based on different filtration media and application scenarios, air filters can be categorized into multiple types. Understanding the characteristics and application scenarios of various air filter types enables us to select the appropriate air filter and improve indoor air quality. Simultaneously, with technological advancements and heightened environmental awareness, future air filters will evolve toward greater efficiency and environmental sustainability, bringing more convenience and health protection to our lives.
