Particle Counter Market Outlook:
Particle Counter Market size was over USD 666.62 million in 2025 and is poised to exceed USD 1.64 billion by 2035, growing at over 9.4% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of particle counter is estimated at USD 723.02 million.
The growth of the market is primarily attributed to the growing demand for positive air pressure cleanroom systems which are normally used for research, aerospace, military & defense applications, optics, electronics, and others. As per data, more then 10,000 positive air pressure cleanroom systems have been installed in United States in 2021.
A particle counter diagnoses and monitors the particle contamination within specific clean media that include air, water, and chemicals. It is an essential tool for detecting and counting physical particles. Particle counters are used in clean room laboratories, households, industries, and others to measure and maintain a desired level of cleanliness. With the rising need to maintain air quality index with deteriorating indoor air quality as well as rising household pollution, the demand for particle counters is on the rise amongst households, which in turn, is expected to create massive revenue generation opportunities for the key players operating in the global particle counter market during the forecast period. According to the World Health Organization data, each year 3.2 million people die due to household air pollution globally.
