September 12, 2023 - Scottsdale, AZ; and Auckland, New Zealand – Piera Systems Inc. (“Piera”) and MACSO Technologies (“MACSO”) are excited to announce their strategic partnership to combine Piera’s state-of-the-art hardware and accurate air quality data with MACSO’s AI/ML software platform to accelerate the development and deployment of new pollutant models greatly. While existing air quality monitors can notify their users that the air quality is bad, this technology points out the source of the air pollution. This powerful capability to classify and profile sources of pollution enables customers to mitigate air pollution quickly and effectively. By applying MACSO’s proven AI/ML software platform to the highly accurate air quality data generated by Piera’s Intelligent Particle Sensors (“IPS”) and Canāree Air Quality Monitors (“AQMs”), customers can produce pollutant models and iterate for further accuracy at a much faster pace than before. Originally developed heuristically, Piera’s vape/smoke algorithm was deployed 8x faster using MACSO’s software and improved accuracy by 15%. The flexibility and repeatability of MACSO’s software platform enable further refinement of this accuracy as more of Piera’s devices get deployed in the field. The ability to remotely update pollutant models keeps deployment costs to a minimum while improving overall accuracy. Along with vape/smoke detection, which is critical for schools, hospitals, and hotels to ensure healthy environments, Piera and MACSO are applying this highly effective marriage of accurate data with proven AI/ML software to various applications and industries, including classification of construction dust in industrial environments and wildfire smoke which are increasing in frequency around the world. Understanding the nature and sources of pollution allows the deployment of targeted mitigation techniques and adapting them in real time, which can result in substantial energy savings. “The ability to classify the sources of air pollution is a huge milestone vastly improving the effectiveness of mitigation techniques resulting in healthier air faster and tremendous energy savings,” said Vincent Ratford, CEO of Piera Systems. “We couldn’t be more excited for this collaboration with MACSO as it helps us classify new pollutants and unlocks new applications faster than ever.” “Building on the success of our AI/ML platform deployments to improve animal health, we were able to quickly extend our platform to analyze air quality data and accurately classify pollutants,“ said Saba Samiei, Founder and CEO of MACSO Technologies. “Accurate data is essential to successfully applying AI/ML techniques, and we are proud to partner with Piera to enable better air and improve human health.” Applications include:

• Schools need to monitor when students vape in bathrooms and change rooms in real time. Statistics show that up to 20% of all high school students vape. The fastest growing segment is 10 to 14-year-olds. Canāree can assist with any school's no-vaping policy.
• Hospitality customers like hotels, home shares, and cruise ships can get real-time alerts when a guest smokes in a hotel room. A rapid response to such events leads to lower cleaning costs, fewer chargebacks, and greater customer satisfaction.

Indoor air quality directly and substantially impacts human health, from loss of productivity to causing serious diseases, including lung cancer, Alzheimer’s, and cardiovascular diseases. The smallest particles, less than 1 micron, are the most dangerous as they are readily absorbed into the bloodstream. Piera’s Canāree AQMs and IPS technology are independently certified to detect these sub-micron particles, which powers MACSO’s AI/ML software to classify pollution sources accurately.
