  • Outdoor Pollution: Carbon Monoxide

    CO or Carbon Monoxide is a colorless and oderless gas. If inhaled constantly or the concentrations are too high, it can affect our health severely. Vehicles and other machinery that burns fossil fuels represent the most significant sources of CO.
  • Air quality index guide: What should you do in each level.

    Particle pollution is one of the most common pollutants, and often it is not clear what we can or should do in each air quality index level. There are six levels, from good to hazardous. 
  • Ultrasonic humidifiers, a source of PM2.5?

    Outdoor air quality is unpredictable. The weather and atmospheric conditions can change from one day to another. Environmental pollution, car density, and even daily activities like smoking and lighting fires can affect the outdoor PM2.5 concentrations. In a sense, indoor air should be easier to maintain clean and breathable. But what if there is a silent enemy inside your home?
  • Indoor AQI during wildfires

    During an ongoing wildfire, the fire itself, the smoke and the ashes can affect your health. The outdoor air has higher than usual particulate matter concentrations and is unhealthy to breathe. This unhealthy air can also come inside houses and buildings, making the indoor air unhealthy to breathe too.
  • High levels of PM2.5 in the air

    When the AQI (Air Quality Index) in your area shows extremely high levels of PM2.5 or your PurpleAir sensor shows a health alert, it means that pollution is hazardous at these levels. Consider these steps to reduce your exposure.
  • What is Particulate Matter (PM)?

    PM - which stands for particulate matter or particle pollution - is an intricate mixture of liquid droplets made up of acids (like nitrates and sulfates), ammonium, water, black carbon, organic chemicals, metals, soil material, and air-borne particles.
