Frequently Asked Questions
Do indoor air quality monitors need calibration?
Most modern monitors do not need frequent manual calibration as they use advanced smart chips. However, it is good practice to check the manual for specific calibration procedures. Some models may require occasional updates to ensure accuracy over time.
Can these monitors detect carbon monoxide?
Some monitors include carbon monoxide detection while others focus on PM and VOCs. Always check the product description for specific gas detection capabilities. CO detectors are life safety devices and should not be replaced by standard monitors.
Do I need a subscription to view data?
Most monitors allow you to view live data without a subscription. Some apps offer premium features for cloud storage or detailed historical graphs. Check the product details to see if any features require paid plans.
How long does the battery last?
Battery life varies by model ranging from a few hours to over 20 hours on a single charge. Plug-in models do not have batteries and offer continuous monitoring. Consider your portability needs when selecting a device.
What is the difference between PM2.5 and PM10?
PM2.5 refers to fine particulate matter that is 2.5 microns in size and can enter lungs deeply. PM10 refers to larger particles that are up to 10 microns. Both are important indicators of air pollution levels.
How often should I check the air quality?
Continuous monitoring provides the best insight into daily air trends. If you use a portable unit, check it periodically especially when cooking or cleaning. Real-time alerts help you stay aware without constant manual checks.
Can I use these in my office?
Yes, many monitors are designed for office environments and feature quiet modes. They help ensure staff health and productivity by tracking CO2 and VOC levels. Just ensure the device has the necessary certifications for office use.
Is Wi-Fi required for operation?
Some models require Wi-Fi for remote alerts and data export while others work via Bluetooth or locally. Check if the device can function without Wi-Fi if you have connectivity concerns. Local display often works independently of internet access.
