Get to know your Air Quality sensor Readings

When It Comes To Indoor Air Quality, Awareness Is Half The Solution!

HALO Smart Sensor - Health - Air Quality

Air Quality Index

Air Quality Index provides a rolling average of the air quality conditions that individuals are breathing over the course of a few hours. Many facility maintenance engineers, principals, office managers, property owners, and even  CEOs are surprised to learn that their indoor air quality is less than desirable for workers, patients, residents, and guests.

HALO follows EPA standards to measure air quality.

Operates in Long Measurement Cycles for General Air Quality.

Number of Contaminants Sampled in HALO Smart Sensor: 4-5.

Air Quality Index Factors:

Particulate Matter (2.5 μm, 10 μm) • Carbon Monoxide (CO) • Nitrogen Dioxide (NO₂)

HALO Smart Sensor - Health - Particulates

Particulate Matter (PM)

Particulate matter, or PM, is a mix of particles and droplets in the air. PM varies in shape and size, but those of 10 micrometers in diameter or smaller can adversely affect your health because they can be inhaled. PM 2.5 refers to fine particulate matter – with a diameter of two-and-one-half microns or less.

Sufficient exposure to PM can irritate the eyes, nose, throat, and lungs, leading to allergy-like symptoms and shortness of breath in otherwise healthy people. It can also exacerbate existing medical problems, such as asthma and heart disease. PM 2.5 is considered the world’s single biggest environmental health risk.

Indoor PM levels can be influenced by outdoor sources like vehicle exhaust, wildfires, and power plant emissions. But many indoor activities produce PM as well: cooking, burning fireplaces, and smoking are just a few common sources.

HALO Smart Sensor - Health - CO

Carbon Monoxide (CO)

Carbon monoxide is a well-known hazard – an odorless and colorless gas that can be lethal in high concentrations. Even at lower levels, when emitted by fuel-burning appliances, it can cause health problems such as confusion and memory loss. Monitoring indoor air quality for carbon monoxide levels is crucial for safety; utilizing air quality sensors to detect and manage exposure risks for CO is a logical basic step.

HALO Smart Sensor - Health - NO2

Nitrogen Dioxide (NO2)

Nitrogen dioxide (NO₂) is a byproduct of natural processes and human activities. Chronic exposure to NO₂ is linked to severe health issues, including hypertension, diabetes, cardiovascular disease, and even death. The presence of nitrogen dioxide in the atmosphere makes it a significant air pollutant, underscoring the need for robust air quality monitoring systems. Utilizing air quality sensors to track NO₂ levels can help mitigate health risks and contribute to effective air quality management.

"For air quality index, I think it’s going to be eye-opening to a number of schools. They're going to be surprised to really see how bad the air quality is.”

Indoor air quality can be significantly affected by outdoor sources of particulate matter like vehicle exhaust, wildfires, and factory emissions, while indoor activities such as cooking, using fireplaces, and smoking also contribute to indoor particulate matter levels. Carbon monoxide from gas utilities and nitrogen dioxide from fossil fuels, methane, and manufacturing processes easily gets into indoor air supplies. This underlines the need for affordable air quality sensors such as HALO for indoor air quality monitoring to ensure a healthy living or working environment for occupants and guests.
