Frequently Asked Questions
What should I do when my air quality monitor shows poor readings?
Open windows for ventilation if outdoor air is clean, run an air purifier, or identify the source — cooking, cleaning products, and off-gassing furniture are common culprits. High CO2 means the room needs more fresh air. High PM2.5 during wildfire season means close windows and run a HEPA purifier.
Where should I place an air quality monitor?
Place it at breathing height (3-5 feet) in the room where you spend the most time, typically the living room or bedroom. Keep it away from windows, vents, and cooking areas for the most representative readings. Some people move it between rooms weekly.
Do I need an air quality monitor if I have an air purifier?
Yes. An air quality monitor tells you when to run your purifier and verifies it's actually working. Many people run purifiers 24/7 unnecessarily, or don't run them when they should. A monitor helps you use your purifier efficiently and confirms it's making a difference.
