Placement Tips:

Proper product placement ensures it can provide accurate readings.

  • Make sure it is at the right height and has good airflow
    • Height: place at sitting or standing level, typically 3 to 6 feet (0.9 to 1.8 m) above the floor.
    • Airflow: include at least 2 inches (5.08 cm) of clearance from walls or other solid objects.
  • Avoid placing by direct sunlight or near heat sources
  • Avoid placing in an area where airflow changes often, such as by air conditioning and heat vents,
    fans, doors, or windows

Indoor air quality can have a significant impact on your health and comfort. With the AcuRite AIR™ Indoor Air Quality Monitor, you’ll know the PM2.5 concentration, temperature, and humidity level inside your home or office at any time. Maintaining clean air can help minimize negative health effects associated with bad air quality, while increasing productivity, energy, and good health.

What is PM2.5? PM2.5 are microscopic air pollution particles that measure 2.5 micrometers or smaller and can remain suspended in the air for long periods of time. If inhaled at a high rate over time, these particles can potentially deteriorate lung function. PM2.5 can be emitted from wildfires, vehicles, airplanes, and even backyard woodburning. Given that these particles pose the greatest risk to health compared to other air pollutants and are the most commonly found pollutants in the air, monitoring the PM2.5 level is extremely important.

Examples of PM2.5 This type of particulate matter is typically generated from combustion activities but can also be of natural origin. Major sources of PM2.5 include fireplaces, vehicle engines, and coal-or natural gas-fired power plants. Sea salt, dust, pollen, black carbon from wildfires, and volcanic ash are all considered natural sources of PM2.5. Your AcuRite AIR™ Indoor Air Quality Monitor may register higher PM2.5 levels than normal while you are cooking, using a fireplace, smoking, using unvented space heaters or kerosene heaters, or during some hobbies. 




The AcuRite AIR™ Indoor Air Quality Monitor has the following accuracy standards:

  1. PM2.5:
    1. +/- 10µg/m3 from 0µg/m3 to 100µg/m3
    2. +/- 10% from 100µg/m3 to 500µg/m3
