PM10 vs. PM2.5: Differences, Risks & Which Filter You Need | Filterbuy.ca

Welcome to the audio version of the following web page: https://filterbuy.ca/resources/air-quality-aqi/pm10-vs-pm25-particulate-matter-explained/ In this episode, we explore the difference between PM10 and PM2.5 and why particle size matters when evaluating air quality. You’ll learn how fine particles such as PM2.5 can travel deeper into the respiratory system, how wildfire smoke can raise particulate levels, and why these pollutants may be especially important for people with asthma or other respiratory sensitivities. We also discuss how outdoor air quality, wildfire smoke, and changing particulate levels can affect conditions inside the home. Understanding how smoke moves indoors and how long exposure can persist can help households make more informed decisions about ventilation, filtration, and reducing exposure during poor air-quality events. For cleaner air inside the home, choosing an HVAC filter designed to capture fine particles, keeping it clean, and replacing it on schedule can help support better indoor air quality. Filter thickness, MERV rating, airflow, and proper fit all matter, especially when smoke, dust, and other airborne particles place additional demands on the HVAC system.
