Air Quality Testing

NextDay Inspect® Air Quality Testing Includes

  • Particulate matter (PM);

    These are solid and liquid particles suspended in the air, many of which are hazardous. This complex mixture includes both organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets. These particles vary greatly in size, composition, and origin. We measure PM10, PM2.5, and PM1; these correspond to PM of < 10 µm, PM < 2.5 µm, and PM < 1.0 µm respectively.

  • Total Volatile Organic Compounds (TVOC)

  • Formaldehyde (HCHO)

  • Total Air Pollution Level

Air Quality Assessments

Pollutants commonly found in indoor air can cause many harmful effects, there is considerable uncertainty about what concentrations or periods of exposure are necessary to produce specific health problems. People also react very differently to exposure to indoor air pollutants.  It is prudent to try to improve the indoor air quality in your home even if symptoms are not noticeable

Outdoor Air Quality

Local air quality affects how you live and breathe. Air quality can change from time to time. The U.S. Environmental Protection Agency (EPA) and local air quality agencies provide information about outdoor air quality. The Air Quality Index or AQI is used to provide local air quality; how unhealthy is the outdoor air. AQI can be thought of as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern; see the table below.


Air Quality Index  Health Concern Colors
AQI  range:
    air quality 
color symbology
0 - 50 Good Green
51 - 100 Moderate Yellow
101 - 150 Unhealthy for Sensitive Groups Orange
151 - 200 Unhealthy Red
201 - 300 Very Unhealthy Purple
301 - 500 Hazardous Maroon

Indoor Air Quality (IAQ)

This the air quality within a building structure, i.e. a home or place of work, especially as it relates to the health and comfort of building occupants. Health effects from indoor pollutant exposure may be experienced soon after exposure or, possibly, years later.

    • Immediate Effects; Some health effects may show up shortly after a single exposure or repeated exposures to a pollutant. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Such immediate effects are usually short-term and treatable. Sometimes the treatment is simply eliminating the person’s exposure to the source of the pollution if it can be identified.
    • Long-Term Effects; health effects may show up either several years after exposure has occurred or only after long or repeated periods of exposure. These effects, which include some respiratory diseases, heart disease, and cancer, can be severely debilitating or fatal.
