How does an air filter contribute to improving indoor air quality?


Posted February 6, 2023 by AirfilterCartridge

Air filters work on the principle of drawing unclean surrounding air to pass through their filter medium with fine openings. The larger unwanted particles are trapped in the opening of the filter medium and are separated from the normal air passing.
 
At present, air pollution has become the world's biggest environmental and health risk linked to around 7 millions of deaths. According to a recent report, exposure to indoor and outdoor air pollution can become the prominent reason behind the occurrence of cardiovascular diseases like ischemic heart disease, strokes, and cancer. Although the role of air pollution in the development of respiratory diseases like chronic obstructive pulmonary disease and respiratory infection is known to all. Both outdoor and indoor pollution affects the health of people, but according to a recent study, the impact of indoor air pollutants on the human body is alarming. Therefore the use of air filters and cleaners is suggested to improve the indoor air quality.

What do you understand about air filters?

An air filter is a device that is designed and manufactured to remove air-borne pollutants, particles, and other microorganisms that are harmful to health and also to the ecosystem. In various industrial facilities, air filters are used to preserve the quality of materials, products, and equipment from damage. In industries, a clean room environment mainly depends on the air filters that control the particle count. Stack and exhaust gases are filtered and cleaned before releasing them into the atmosphere. Although air filters are found in many offices, homes, laboratories, commercial spaces, hospitals, and clinics. Industrial air filter cartridges effectively remove dirt, dust, odors, aerosols, smoke, molds, viruses, toxic gases, bacteria, and other pollutants and particles that could exist in the ambient air. Air pollutants can aggravate and cause respiratory illnesses, allergies, skin disorders, and other forms of issues.

How do air filters work?

Air filters work on the principle of drawing unclean surrounding air to pass through their filter medium with fine openings. The larger unwanted particles are trapped in the opening of the filter medium and are separated from the normal air passing. When the air leaves the filter, there will be a reduced particle content in it. Air filters enhance the filtration efficiency as dirty particles form a layer on the upstream side of the filter media which aids in the screening of the other particles. Therefore it is essential to replace the filter medium at regular intervals of time to prevent it from clogging, restricting, or binding airflow.

Different types of air filter media

Filter media is the main filtering component present in the air filters. They are highly responsible for capturing unwanted particles present in the air for preventing their circulation in the air. They comprise a single piece of synthetic mesh or fiber with microscopic perforations. This is carried and contained in a frame and installed in the air filtering equipment. These air filter media are classified as a non-pleated or pleated filters.
