Q: How do you measure air quality?

A: We measure the Particulate Matter (PM) in the air. We focus on PM10 and PM2.5.  PM10 represents 'coarse' particles such as dust, pollen, asbestos, and mold. PM2.5 represents smaller 'respirable' particles that embed inside your lungs causing respiratory and cardiac conditions. Examples of these particles include woodsmoke, vehicle exhaust, kitchen fumes, and anything that has been incinerated. 


Q: Why particulate matter?

A: We at TZOA believe in actionable change. With particulate matter you can make changes in your lifestyle to reduce your exposure. Examples are: Changing your commute to avoid high-pollutant areas; buying an air purifier for your home; changing the filters in your home HVAC system; turning on a hood fan in your kitchen while you cook; and locating the cleanest areas to exercise outdoors. With these changes and your TZOA, you will be able to quantify the drop in your exposure and find the best solutions for you and your family.


Q: How do I use TZOA?

A: There are many applications for your TZOA. As it is a wearable, you can attach it to your clothing, purse, bag or backpack as you move about your day. It will collect data and update your smartphone via Bluetooth regularly. When you are at home, you can leave your TZOA in its charging cradle and have it monitor the air quality in your family’s home. We recommend leaving it either in the kitchen, a living area, or a bedroom. 


Q: How does TZOA create a map of my environment?

A: We use the internal sensors along with the GPS in your smartphone to plot your map for you. 


Q: When will TZOA be available to the public?

A: The TZOA wearable enviro-tracker will be available Q3 2017, with more product launches scheduled in 2017 and early 2018. We're excited to show you what we've been up to!


Q: Will there be a monthly subscription fee?

A: No. Buying a TZOA gives you access to the data you collect and the crowd sourced maps. We at TZOA are about social and environmental change; we do not believe that the data should be hidden behind a paywall. There may be paid services for data intensive product features in the future.
