Getting Particular About Particulate Matter

We take 20,000 breaths a day, but do you know what's in the air you're breathing?

We take 20,000 breaths a day, but do you know what's in the air you're breathing? You may think that as long as you can't smell smoke and the sky looks clear, you're in the clear as far as breathing goes.

But microscopic dust particles in the air, known as particulate matter (PM), can still cause great harm. Air pollution is one of the leading causes of death worldwide—deadlier than smoking, malaria, or AIDS ( One of the main sources of air pollution is particulate matter. According to a study conducted by the Andrew Young School of Policy Studies at Georgia State University, exposure to air pollution may influence the severity of coronavirus ( 

Particulate Matter Comes In Three Sizes

While all particulate matter is microscopic, it is not all the same. The size of the particles makes a difference.


Though we tend to take particle pollution in the form of haze or smog for granted, it can have strong negative effects on your health. Particle pollution includes:

  • Mold spores
  • Dust
  • Smoke
  • Pollen
  • Soot
  • Airborne viruses or bacteria

These types of particulate matter belong to the largest group, PM10. PM10 are inhalable particles, with diameters generally 10 micrometers and smaller (EPA). It's important to understand that the PM10  encompasses smaller particulate matter as well: fine dust (PM2.5) and ultrafine dust (PM1.0).

In addition, PM10 is an irritant for eyes, nose, throat, and airways. Sources like road dust and dust from construction work can pose significant health risks.


PM2.5 is the level of particulate matter that's been making news ever since the West Coast wildfires this past summer. Though PM2.5 is extremely small in size — 30 times smaller than the width of a single hair on your head — it packs a punch.

PM2.5 can have deleterious effects on your heart and lungs. According to a study conducted at Harvard's T.H. Chan School of Medicine, "long-term exposure to PM2.5 increases the number of deaths due to COVID-19 by 8% after accounting for many confounding factors" (


    Unlike the "small is beautiful" slogan that refers to aesthetically pleasing small-scale architecture, the smallest particulate matter is the most dangerous.

    Because these ultrafine dust particles, known as PM1.0, are so tiny, they can infiltrate our bodies more extensively, leading to an even greater risks. PM1.0 particles comprise the majority of indoor particulate matter, so with winter coming, it's crucial to protect ourselves from this invisible health threat.

    Get Smart Air Quality Protection

    The Wynd Halo detects all three types of particulate matter. The most comprehensive air quality monitor on the market, Halo has 14 software-enabled health and comfort metrics, enabling you to take the right course of action throughout the day.

    In addition to PM10, PM2.5, and PM1.0, Halo detects:

    • Smoke
    • Pet dander
    • Pollen
    • Dust
    • CO2
    • VOCs
    • Smog
    • Temperature
    • Humidity
    • Light
    • Noise

    Insights about the air around you can help you make long-term improvements to your environment. Halo recognizes what's in your air and makes recommendations. In addition, Halo can control devices such as smart purifiers, humidifiers, and thermostats to enhance your environment so you can be at your best, whether you're working, resting, exercising, or just breathing.
