Restraints

• The initial and recurring costs for the installation and usage can be considered exorbitant: The expenses in setting up and running indoor air quality monitoring hardware can be extraordinarily high, particularly for small commercial enterprises and household users, which almost completely hampers its adoption. This challenge, depending on the region, inhibits its widespread acceptance or adoption especially in places where economics are a constraint.
• Insufficient appreciation in developing countries: For most of the developing nations, attention and action towards appreciating and protecting indoor air space is basic. This creates a market challenge as both consumer and commercial entities are oblivious of the threats that indoor air pollutants pose and the significance of indoor environmental quality systems.
• Use of low cost sensors brings challenges of data credibility: Inexpensive systems for air quality monitoring often employ poor quality sensors that are prone to return unreliable data. Such unreliability makes it easy for users to misjudge the condition of indoor air and hence take no or ineffective measures to rectify poor indoor air.
• Making it to work with other systems in the structure is a challenge: Bringing new air quality evaluation devices into older structures or existing facilities’ automated management systems is usually not easy. This often comes with extra costs on technologies and facilities which may discourage some institutions.

Challenges

• Major Problem in Global Air Quality Monitoring Systems Standardization: The absence of one-size-fits-all air quality monitoring systems has led to a myriad of problems including inconsistencies in databases as well as different regions having different accuracies. This enhances the risk associated with the production of globally compliant goods that do not raise issues of legal non-compliance.
• Overreliance on factors such as the external environment, policies: It is difficult to dissociate the increase in the market for air quality monitoring equipment and the policies put in place to protect the environment. Such regions may not experience such notable systems demand, thus restricting markets growth in such regions.
• Compromise Between Cost and Efficiency of Systems: Cost benefit is one element that challenges the market. While there is a high demand for cheap quality air monitoring devices from the consumers and the businesses alike, cheap usually does not come with efficiency and precision, thus causing a disconnect between the products and the utmost fulfillment of user needs.
• Incorporating Advanced Monitoring Technologies in the Rehabilitation of Old Buildings: The majority of the old structures lack the capability of accommodating modern air quality monitoring systems. Retrofitting may be costly and labor intensive as the space’s cooling, heating and electrical systems will require extensive alteration which may deter companies from adopting the technology.
