Seeing is Believing
Measurement is Proof
Air pollutants—such as chemicals, smoke, dust, or allergens—aren’t always visible. Tiny airborne particulates (such as PM2.5) are especially dangerous because they can penetrate deep into the lungs and potentially cause acute and/or chronic health effects. Watch a video about the danger of aerosolized dust and particulates.
Pollution can affect air quality across a region or city, but can also be localized to a community, neighborhood, or even a single building. Hyperlocal air quality could be very different from the regional air quality as reported by regulatory or governmental agencies, such as the US Environmental Protection Agency's (EPA) AirNow website.
BlueSky™ Environmental Air Quality Monitors provide trusted results to help protect what's important. Designed for community watch groups, local EPA organizations, fugitive dust monitoring, government agencies, and municipalities, TSI® offers over 50 years or industry experience to support the needs of those looking to utilize low-cost gas sensing (CO, CO₂, NO₂, SO₂, O₃) capabilities, in addition to measuring particulate matter (PM) mass concentrations, temperature, relative humidity (RH), and barometric pressure (BP).

To help answer these questions and more, TSI is releasing our hyperlocal small, low-cost air quality monitoring instrument. We're pleased to introduce the new BlueSkyTM Air Quality Monitor.
Traffic, idling vehicles
When there is an increase in traffic, especially around intersections, PM levels can increase due to vehicle exhaust, brake pad dust, and other contaminants from the road.
All the vehicles in parking garages (especially during commuting times) can lead to increased levels of particulate matter due to high concentration of exhaust and poor ventilation.
Construction sites involve large machinery, both emitting exhaust and kicking up dust and dirt into the air, increasing levels of PM which can cause air quality issues.
Parks draw pedestrians (especially children, who are more susceptible to poor air quality), but sometimes the parks are located in an area with potential air quality problems. In this case, it is next to a construction site, which could be kicking up dust, dirt, and particulate matter into the air and potentially decreasing the quality of the air.
School areas are often crowded with children during weekday commuting times. Automobiles are idling or waiting in a long line, dropping off or picking up students, and school buses are pulling up constantly and letting students out. This can lead to potential air quality issues in the hours just before school starts and just after school lets out.
