Air Quality Monitoring Market: Overview

Both indoors and outdoors, an air quality monitoring system detects and monitors contaminants in the air such as carbon monoxide, nitrous oxide, sulfur dioxide, and volatile organic compounds. The requirement for air quality monitoring has grown as a result of the need to maintain air quality, as poor air quality contains harmful contaminants that cause health problems.

The growth of the air quality monitoring market has increased due to an increase in awareness of chronic obstructive pulmonary disease, asthma, cardiovascular difficulties, and lung cancer, all of which have become increasingly common as pollution levels have risen.

Moreover, favorable government policies on air pollution monitoring and management, as well as an increase in public-private partnerships for air quality monitoring, have increased the demand for air quality monitoring systems. In recent years, increasing economic conditions in developing countries have hastened the pace of industrialization, resulting in higher levels of air pollution.

Toxin emissions such as carbon monoxide and sulfur dioxide poison the air. As a result, there has been an increase in the demand for air quality monitoring systems to regulate and monitor the amount of pollution in the atmosphere. Furthermore, indoor air pollution is becoming a major issue.

As a result, house or building owners, industrial professionals, and facility workers install air quality monitors to ensure a healthy indoor environment. The global increase of the air quality monitoring market has been considerably fuelled by technological advancements and growing acceptance of the smart home concept.

Air Quality Monitoring Market: Driver

 Public and private efforts that promote environmental protection and public awareness

A variety of positive initiatives have been implemented by the government, non-governmental organizations, and the corporate sector to minimize and reduce air pollution through public awareness campaigns and programs. Such programs and activities not only help to improve public awareness but also play a vital role in drawing international organizations’ attention to the existing and future problems of air pollution that the globe faces. Many government and non-governmental groups work tirelessly to attract national and worldwide societies' attention to the devastation caused by air pollution on the health of living beings and the environment. The EPA (the United States Environmental Protection Agency), Clean Air in London (London), Little Ninja (UK), Earthjustice (US), and German VCD are some of the prominent public groups involved in raising public awareness about the environmental effects of air pollution (German Sustainable Transport Association). This feature is expected to boost market expansion in the approaching years.

Air Quality Monitoring Market: Restraint

Expensive product

The high installation and maintenance costs of traditional air monitoring systems limit market expansion. The high costs of purchasing, installing, and maintaining AQM sensors, as well as the establishment of AQM stations, are exacerbated by the implementation of stringent pollution control policies in mature markets, which necessitate regulatory compliance for effective air pollution monitoring, data collection, and data surveillance. As a result, the high installation costs of AQM stations, as well as the premium price of sophisticated monitoring systems, are expected to restrict their optimum market development over the research period—though mostly in emerging nations.

Air Quality Monitoring Market: Opportunity

R&D and technological developments are ongoing.

Continuous R&D and commercialization of advanced AQM systems (such as miniaturized devices, nanotechnology-based systems, infrared spectroscopy, and remote-sensing instruments) are likely to provide considerable growth prospects for both established and developing AQM players. As a result, a growing number of industrial actors and research institutions are working on creating and commercializing sophisticated AQM solutions. For example, nanotechnology-based AQM solutions have various procedural advantages, including real-time monitoring capabilities, device downsizing, higher analytical efficacy, and low production costs. Pipeline development and expanded market availability of technologically sophisticated air pollution monitoring systems are expected to give opportunities for market growth in the future years.

Air Quality Monitoring Market: Challenge

Reforms to reduce air pollution are being implemented slowly.

The sluggish implementation of air pollution rules is one of the primary issues associated with the market for air quality monitoring systems. Several growing countries (including China and India) have been accused of being reluctant to enact severe environmental pollution monitoring standards over the last decade. Similarly, a scarcity of well-trained and skilled technical professionals to carry out pollution monitoring and control measures, as well as a lack of R&D infrastructure to develop affordable air pollution monitoring technologies in developing countries, are stifling the implementation of effective pollution monitoring and control reforms.
