EVALUATING AIRTHINGS VIEW PLUS AND WAVE MINI FOR INDOOR AIR QUALITY RESEARCH: A MINI REVIEW

Indoor air quality has a significant impact on human health. It affects respiratory health, cognitive performance, and overall well-being. The demand for low-cost air quality monitoring equipment such as Airthings View Plus and the Wave Mini is becoming popular in indoor air quality monitoring, particularly in residential and educational contexts. This necessitated the examination of their accuracy and reliability for both personal and research purposes. A peer-reviewed literature published in Scopus, Web of Science, Google Scholar and PubMed between January 2018 and June 2025 was searched. A total of 27 suitable papers were examined, with fewer than half containing direct comparisons to reference-grade instruments. The review discovered that both Airthings devices provide practical solutions for small-scale and personal IAQ monitoring; however, their metrological accuracy varies significantly depending on pollutants and ambient conditions. The View Plus showed moderate agreement with reference devices for CO₂ and VOC readings. However, it had performance constraints for PM₂.₅ in high-humidity conditions. The Wave Mini was much preferred for its portability and ease of use but cannot detect PM2.5. It also shows fluctuation in VOC accuracy due to poor calibration. While both devices are appropriate for improving IAQ awareness and use in community-based and educational programmes. They currently lack the precision and calibration standards needed for regulatory or high-risk scientific research. Future work should prioritise validation against internationally recognised protocols (e.g., EPA, ISO 17025) and look at machine learning-based calibration models to solve long-term sensor drift
