The Different Types of Commerical Air Filters

Commercial air filters are devices that are used to remove dirt, dust and other particles in the air, keeping it clean and breathable. Over the last few decades, the air-filtration industry has advanced, and manufacturers have created new products that are more affordable and effective in improving indoor air quality (IAQ). As a result, the cost of installing and operating air-filtration equipment in institutional and commercial facilities has gone down.


There are four major types of commercial air filters:

1) Fiberglass Filter
This is the most common type of filter in many parts of the world. The throwaway air filter is made from layered fiberglass pieces that are laid over each other to form the filter media. The fibers are usually reinforced with metal grating to prevent collapse or failure.

2) Pleated and Polyester Filters
These air filters are similar to fiberglass filters but have a superior dust-stopping ability and a higher airflow resistance.

3) Washable Air Filters
These are the least common filters in the market. The efficiency of the filter is determined by the amount of dust piled up along the cloth. They are mostly used in industrial applications.

4) High-Efficiency Particulate Absorbing (HEPA) Filters
HEPA devices filter the air passing through them at a very fine scale. The U.S. Department of Energy and its contractors use HEPA filters that are capable of filtering 99.7 percent of particles measuring 0.3microns or larger.

Major Types of Filtration Systems

Air filters are used in various commercial, industrial and medical sectors and various applications require different types of filters. The most common filters used are Ionic, carbon, and UV light air filters. Ionic air filters use voltage to charge up air molecules. The commercial-air-filtersilters produce negatively charged ions which attract dust particles in the air, similar to the way static electricity does. Commercial air filters are especially good at removing the particles that get in touch with the ions are de-ionized and removed from the air stream.

Carbon air filters use treated carbon to absorb odors and trap particles in the air. Carbon can be treated with oxygen, making it highly absorbent. This treated carbon is used to filter cigarette smoke and trap chemicals and gasses.UV light filters use a UV reaction with titanium dioxide to break down particles in the air. These are mostly used in the medical industry together with HEPA filters. The reaction that occurs between UV light and titanium dioxide can neutralize harmful particles in the air such as bacteria and mold.The filters above have many uses in different sectors. They are crucial in many industrial processes and helpful in many domestic applications and be attain by contacting various b2b service providers.
