What parameters should be monitored for indoor air quality?

Key parameters include CO₂, VOCs, PM2.5/PM10, temperature and humidity. Air pressure is also sometimes included. Each parameter offers insights into air freshness, safety and comfort.

Why is real-time monitoring better than periodic checks?

Unlike periodic measurements, which may miss key events, real-time data allows you to catch issues such as poor ventilation or pollutant spikes before they impact occupant health or comfort.

Can ista IAQ systems integrate into existing building infrastructure?

Absolutely. Our indoor air quality systems are compatible with building management systems (BMS) platforms and can also operate independently via cloud dashboards and mobile apps.

Are wireless IAQ sensors reliable in large buildings?

Yes, modern wireless protocols such as LoRaWAN provide reliable long-range, low-power communication, even in buildings with complex layouts.

How does IAQ monitoring help with energy efficiency?

By aligning the operation of your HVAC system with your actual air quality needs, you can avoid over-ventilating, overcooling or leaving it on for longer than necessary — reducing both your energy costs and your emissions.

For healthier buildings: ista's real-time air quality measurement.

Let state-of-the-art sensors track and manage key parameters like CO₂ and VOCs in real-time. Our modern Indoor Air Quality (IAQ) monitoring technology provides the data needed to improve comfort, protect occupant health and optimize building performance.

Why smart IAQ monitoring matters.

Detect unhealthy air before it affects occupants

Prevent damage by mold and moisture

Support energy efficiency & sustainabilty through better HVAC control

Track compliance with indoor air quality guidelines

Advanced sensor technology for reliable IAQ data.

Indoor air quality directly impacts how people feel, think, and perform — yet many buildings still lack real-time insight into what's in the air. Our smart IAQ monitoring systems provide continuous data on important parameters such as carbon dioxide, volatile organic compounds (VOCs), temperature, humidity and fine particulate matter (PM2.5/PM10).

This data enables facility managers and building owners to make proactive decisions that reduce complaints, improve health outcomes and create more efficient indoor environments. Whether you manage a residentail tower, office, or high-traffic public space, IAQ monitoring forms the critical foundation of healthy building operations.

How to measure what matters for health, comfort and efficiency.

IAQ monitoring systems use a network of digital sensors to continuously track and report on indoor environmental conditions. These sensors measure various factors, such as CO₂ levels to evaluate ventilation and occupancy, VOCs to detect harmful emissions, and particulate matter to assess filtration performance.

They also measure temperature, humidity, and sometimes air pressure. The data is transmitted wirelessly — often via LoRaWAN or Wi-Fi — to a centralised platform or building management system, where it is analysed and visualised in real time. Alerts and trend reports help operators to identify problem areas early on and to make targeted adjustments to HVAC settings, cleaning routines or space usage.

Track what matters most

Monitor key indoor air quality indicators like CO₂, VOCs, and PM2.5 in real time to protect health and meet regulations.

Prevent problems before they spread

Maintain optimal humidity and ventilation to reduce the risk of mold growth, Sick Building Syndrome, and indoor discomfort.

Align optimal air quality with energy goals

Use accurate data to fine-tune HVAC operation — reducing overcooling, energy waste, and unnecessary runtime across your building.

A hospital corridor with bright ceiling lights and several doors along the walls. Several medical professionals are walking around: some are wearing lab coats, others blue surgical scrubs. In the centre of the image, two people are walking side by side and talking to each other while holding documents in their hands. In the foreground, a nurse is walking down the corridor with a yellow document, while other staff members are moving towards the ward. An exit or orientation sign can be seen at the end of the corridor. The scene conveys a typical day in a hospital with team communication, documentation and movement between treatment areas.
