IQAir AirVisual pro air quality monitor. It’s not cheap( around 270$) but in my honest opinion it’s worth every penny. Because it’s very durable (more than approx. 4-5 years measurement) and has very good quality of measurement and visualization. IQAir AirVisual pro air quality monitor doesn’t have Volatile Organic Compounds (VOC) measurements which is a small disadvantage. However, AirVisual pro has 3 critical air quality measurements (CO2, PM2,5 and air humidity).
When we are talking about Air quality Matters, I truly recommend considering meters with Carbon dioxide (CO2) Measurement. A lot of people don’t care about CO2 or are unaware of this measurement. However, CO2 is extremely important in everyday life and we have very often problem with high density of CO2 level. CO2 Level over 1000ppm causes increasing fragrance sensitivity…
Air Quality parameters:
- CO2 level as I mentioned is an extremely important parameter and is unevaluated by most people. IQAir AirVisual pro air quality monitor recommends by colors (Green, orange, red) which CO2 level is good, moderate and bad. Color recommendations are used also for Air pollution.
- Air pollution – It’s Particulate Matter smaller than 2.5 μm in diameter. Pollutants PM2,5 and PM1 are so small that they penetrate the cell membrane. That’s the reason why pollutant is so dangerous. Air pollution is also expressed in graphical and colors. Important IQAir AirVisual pro air quality monitor shows pollutions both in µg/m3 Particulate Matters PM2.5 and also in the Air Quality Index.
- Temperature. There is no recommendation to right temperature. It’s very relative. My recommendation is keep in winter no between 19-22C – More about it: https://iqbuilding.eu/index.php/2022/02/20/cheapest-and-healthiest-humidifier-healthy-air-1/
- Humidity – It’s very important because especially low humidity lowers our immunity. Unfortunately, AirVisual doesn’t show any recommendation but only measurement. So, you need interpreted measurements. The best level of humidity is between 40-60% (max 50-55% in winter). Humidity lower than 30% and higher than 70% is unhealthy

Advantages
Durability: AirVisual Pro Durability for measuring indoor air quality is insane. My AirVisual Pro has more than 5 years and was used by many people, was traveling and still working perfectly. All measurements I checked with certificated gauge and deviations were negligible
Auto CO2 calibration
One-time ago Co2 level I realized that in ambient air sows CI2 level much lower than 400 ppm (we have around 400-430 ppm in ambient/fresh air). So that was suspicious. After few days’ measurement was correct (400 ppm in the ambient air). I’ve dug in producent website https://www.iqair.com/ I realized that IQAir AirVisual pro air quality monitor has periodical autocalibration procedure.
Online Application & online data.
You can track measurements, history, outside conditions, etc. via mobile app or just via web browser.
Good quality sensors/measurements.
I’ve checked with lots of different gauges (also these certificated) and measurements were accurate. For home use is better than needed.
Disadvantages
Perhaps high price – it’s not too cheap but very good quality and proven durability.
IQAir AirVisual pro air quality monitor could show recommendations of humidity like in CO2 and air pollution.
