Background
For over 25 years, Perfect Pollucon Services has specialized in Indoor Air Quality Monitoring Services, helping businesses create healthier and more productive workspaces.
One of our recent projects involved conducting indoor air quality (IAQ) monitoring for a global telecommunications leader that operates large office spaces and data centers across India.
Indoor air quality is a crucial yet often overlooked factor in workplace health. Employees spend nearly 90% of their time indoors, and poor air quality can lead to reduced productivity, increased absenteeism, and long-term health concerns. Our client was proactive in recognizing the need for a healthier workspace and sought our expertise to assess and improve their IAQ.
The Challenge: Identifying Hidden Air Quality Issues
The client approached us with mild but recurring employee complaints related to:
✔ Fatigue and reduced concentration during long working hours.
✔ Mild irritation in the eyes and throat, especially in enclosed meeting rooms.
✔ Occasional stale or stuffy air in certain areas of the building.
✔ Higher-than-normal absenteeism due to respiratory discomfort.
Though these symptoms were not severe, they pointed to potential indoor air quality concerns. The challenge was to identify the root cause and provide data-driven solutions without disrupting day-to-day operations.

Our Approach: Indoor Air Quality Monitoring Services Strategy
Drawing from our extensive experience, we implemented a phased approach to air quality assessment:
1. Preliminary Site Inspection & HVAC Evaluation
Our first step was to assess ventilation efficiency and inspect the Heating, Ventilation, and Air Conditioning (HVAC) system.
🔹 We identified areas with insufficient fresh air intake and improper air circulation.
🔹 Some office zones experienced fluctuating temperatures, leading to employee discomfort.
Our team applied advanced indoor air quality monitoring services to track pollutants like CO₂, PM2.5, and VOCs in real-time
2. Real-Time Air Quality Our Approach: Comprehensive Indoor Air Quality Monitoring ServicesMonitoring
We deployed high-precision air quality sensors to continuously monitor key indoor air parameters over two weeks. The focus was on:
✔ Particulate Matter (PM2.5 & PM10) – Linked to respiratory discomfort.
✔ Carbon Dioxide (CO₂) Levels – Indicator of poor ventilation.
✔ Volatile Organic Compounds (VOCs) – Emitted from office furniture, carpets, and cleaning agents.
✔ Relative Humidity & Temperature – Essential for comfort and air circulation.
3. Data Analysis & Findings
Upon analysis, we discovered:
📌 PM2.5 levels were 35-40 µg/m³ in some areas – Slightly above recommended limits, leading to discomfort.
📌 CO₂ levels exceeded 1000 ppm in closed meeting rooms – Indicating poor ventilation.
📌 VOC concentrations were higher near newly installed workstations – Likely from adhesives and furnishings.
📌 Temperature fluctuations in some zones led to inconsistent comfort levels for employees.
The Solution: Practical, Industry-Proven Interventions
With decades of expertise, we knew that a balanced approach—focused on ventilation, filtration, and source control—was the key.
✅ Optimizing HVAC Performance
- Recommended increasing fresh air exchange rates to bring CO₂ levels below 800 ppm.
- Suggested recalibrating air handling units (AHUs) to improve air distribution.
✅ Targeted Air Purification Measures
- Installed HEPA & activated carbon filters in select areas to reduce particulate and VOC exposure.
- Advised regular maintenance of filters to sustain air quality improvements.
✅ Source Control & Employee Awareness
- Suggested low-VOC cleaning products and eco-friendly office materials to reduce off-gassing.
- Conducted an employee awareness session on maintaining IAQ through simple practices like desk cleanliness and proper ventilation.
✅ Temperature & Air Circulation Improvements
- Suggested balancing air conditioning across different office zones to maintain consistent comfort.
- Recommended adjustments in air diffusers and vent placements for better airflow.
Optimizing Stack Emission Monitoring for a Data Center’s DG Sets
Results: A Noticeable Improvement in Workplace Air Quality
🔹 Within one month, CO₂ levels were reduced to 700-800 ppm, improving employee focus.
🔹 PM2.5 levels dropped by 25-30%, creating a visibly fresher indoor environment.
🔹 VOC concentrations decreased significantly, minimizing irritation complaints.
🔹 Employees reported feeling more comfortable, less fatigued, and more energized at work.
A post-intervention survey showed a 40% reduction in IAQ-related complaints, and the HR team noted a slight drop in absenteeism related to respiratory discomfort.
Studies from CPCB India suggest that PM2.5 levels exceeding 40 µg/m³ can lead to productivity loss in office environments.
Industry Insights: Why Indoor Air Quality Matters More Than Ever
According to the World Health Organization, poor indoor air quality can impact cognitive function and overall well-being, making IAQ assessments crucial for workplaces.
Over the last 25 years, we have observed that many businesses overlook indoor air quality until employee health concerns arise. Here are some key insights from our experience:
✔ Poor IAQ impacts cognitive function – Studies show that high CO₂ levels can reduce decision-making ability by up to 50%.
✔ Neglecting HVAC maintenance leads to hidden risks – Without proper servicing, filters become clogged, worsening air quality.
✔ Post-pandemic, employees expect healthier workplaces – Clean air is now a workplace expectation, not a luxury.
✔ Small IAQ improvements can yield big results – Even simple steps like increasing fresh air intake can boost productivity and employee well-being.
