GZAIR PT02 Pro detects more air pollutants and air quality factors than any other air quality monitor. It tracks Pollen, TVOC, carbon dioxide (CO2), carbon monoxide (CO), PM2.5, PM1.0, Temperature and Humidity.
You may want to know the types of contaminants found in the air:
Pollen: Pollen is an allergen created by trees, grasses, and weeds. The levels of pollen in your home can vary depending on the time of year.
Carbon dioxide (CO2): This gas is what your body breathes out. In small doses, it’s no big deal. If the CO2 levels in your home get more concentrated, it can mess with your sleep or give you a headache. High levels of carbon dioxide can be deadly.
Carbon monoxide (CO): CO is an odorless, colorless gas created by fuel-burning devices like stoves, heaters, and furnaces. This gas is deadly. You can learn more in our carbon monoxide guide.
Volatile organic compounds (VOC): Volatile organic compounds are gases that can cause short- or long-term health problems. They can come from paints, turpentine, office furniture, cleaning products, glues, building materials, and much more.
Particulate matter (PM): These are microscopic solids or liquid droplets. When inhaled, these fine particles can cause health problems. Some types of particulate matter include dust, dirt, smoke, and some pollen. GZAIR PT02 Pro can detect PM 2.5 and PM1.0. This means the device will detect a PM that is 30 times smaller than the diameter of a human hair.
