Particle Counters Market Report 2026

The particle counters market size has grown rapidly in recent years. It will grow from $0.63 billion in 2025 to $0.71 billion in 2026 at a compound annual growth rate (CAGR) of 12.5%. The growth in the historic period can be attributed to growth of pharmaceutical manufacturing, expansion of semiconductor fabrication plants, implementation of cleanroom standards, increased focus on workplace safety, adoption of contamination control practices.

The particle counters market size is expected to see rapid growth in the next few years. It will grow to $1.09 billion in 2030 at a compound annual growth rate (CAGR) of 11.2%. The growth in the forecast period can be attributed to stricter regulatory compliance requirements, growth in biologics and vaccine production, increasing investment in semiconductor fabs, rising demand for indoor air quality monitoring, advancements in sensor and optics technology. Major trends in the forecast period include rising adoption of continuous particle monitoring, growth in portable and handheld particle counters, increasing demand for ultrafine particle detection, expansion of particle counters in cleanroom compliance, demand for high accuracy and real time data logging.

The rising indoor air pollution is expected to propel the growth of the particle counters market going forward. Indoor air pollution refers to the presence of pollutants in the air inside homes, offices, schools, and other buildings. Indoor air pollution is rising due to several reasons, including increased use of synthetic building materials and furnishings, increased use of household chemicals, and increased use of combustion appliances. Particle counters help monitor indoor air pollution by measuring the concentration and size distribution of airborne particles, aiding in identifying potential sources and assessing air quality. For instance, in July 2023, according to the Environmental Protection Agency, a US-based government agency, Americans typically spend about 90 percent of their time indoors, where concentrations of certain pollutants can often be 2 to 5 times higher than levels found outdoors. Therefore, rising indoor air pollution is driving the growth of the particle counters market.

Major companies operating in the particle counters market are focused on developing advanced solutions, such as portable particle counters, to ensure the accuracy and reliability of measurement instruments and equipment. A portable particle counter is a device used to measure and count the number of airborne particles in a specific environment, often for cleanroom monitoring and classification. For instance, in February 2023, TSI, a US-based company, launched the AeroTrak+ Portable Particle Counter, designed to simplify and enhance the reliability of cleanroom particle counting. This new instrument assists technicians with cleanroom classification, monitoring, and root-cause investigations. The AeroTrak+ Portable Particle Counters adhere to global regulatory guidelines and international standards, including ISO 14644-1:2015, ISO 21501-4:2018, EU GMP Annex 1 (2008 and 2022), and China GMP, ensuring straightforward cleanroom classification testing.

In October 2023, Particle Measuring Systems Inc., a prominent US-based manufacturer, acquired Environmental Monitoring Services Irl. Limited and EMS Particle Solutions Ltd. This strategic move supports Particle Measuring Systems' goal to expand its presence in key markets and improve customer service through advanced contamination monitoring solutions. Environmental Monitoring Services Irl. Limited and EMS Particle Solutions Ltd., both based in Ireland, specialize in providing cleanroom monitoring solutions, including particle counters, further enhancing Particle Measuring Systems' capabilities in contamination control.
