Enriching Indoor Air Quality with the Aid of Air Filters

According to Lung Care Foundation (LCF), in India, we breathe 25000 times a day and inhale about 11000 litres of air per day using our Lungs.

These factors are amazing, right?

But why should we take care of indoor air quality?

The quality of the air we breathe determines the health of the lungs as well as other organs. Indeed, clean air is considered to be a basic requirement of human health and well-being. However, air pollution continues to pose a significant threat to health worldwide.

Air pollution can also cause long-term damage to nerves, the brain, kidneys, liver, and other organs. It is also believed that air pollutants cause birth defects.

Indoor air pollution is a complex mixture of pollutants migrating indoors from outdoor air and pollutants generated by indoor sources.

It is, however, very apparent that there has been a continuous deterioration of ambient air and human health with the increase in population, industrialization, and urbanization.

Improper management of transport, primitive roads, high construction activity, and unplanned distribution of industries –all have led to an increase in pollution levels. Commercial townships, buildings, and workplaces adjacent to industries related to wastewater treatment plants, refineries, pharmaceutical units, dyes, textiles, timber and furniture, handicrafts, metals, chemicals, sandstone quarries, steel rolling mills, pulses, oil mills, etc., are responsible for a rise in a variety of outdoor pollutants.

Thereby they are causing an increase in the emission of toxic pollutants such as particulate matter (PM2.5, PM10), and infectious pathogens, such as fungi, bacteria, and viruses in indoor environments.

When inhaled, they are small enough to bypass the protective mechanisms of the respiratory tract and settle in the lung where they may cause respiratory infections (short term infections & long term infections).

The industries that are responsible for emissions need to be equipped with proper air filtration solutions. The people, processes, and environments inside the manufacturing units are also equally important to maintain product quality, workers & staff health, and safety.

Hence the industrial owners, environmental consulting firms, and government authorities should be in the same line to protect the environment (indoor air / clean air)

Several measures are recommended to reduce exposure to contaminants of biological origin (mold, pollen, allergen, dust particles, etc) and non-biological origin (e.g., environmental tobacco smoke, wood smoke, volatile organic compounds (VOC)). With a better understanding of indoor pollutants, new and effective measures have evolved, including the development of indoor air filters, and air purifiers.

Air filtration is frequently recommended as a component of environmental control measures. Indoor air filtration can be provided by whole house filtration via the home’s heating, ventilation, or air conditioning system, by portable room air cleaners, or a combination of the two.

The key attribute of any air filter is a balance of the following:

  • Airflow to assure adequate ventilation
  • Efficiency to filter out a range of small particle sizes, and
  • Capacity to allow for reasonable cost-effective maintenance schedules without adversely affecting airflow and efficiency.
  • The use of HEPA filters traditionally used in hospitals, hospitality environments, food and beverage industries, and pharmaceutical units, has indeed been a significant inclusion in air purifiers. A HEPA filter is standardized at a minimum 99.995% efficiency rating for removing particles greater than or equal to 0.3μm in diameter.

In the air-cleaners, the air was filtered first by a pre-filter, followed by a secondary filter, in which small dust particles were captured by rotation at high speed. The last filter consisted of a high efficiency particulate air (HEPA) type filter.

Technologically advanced air filter systems are now available that efficiently remove particulate matter, resulting in significant health benefits to all building occupants.
