I put it Infront of humidifier and humidity readings raise correctly, similarly when cooking in the house, the AIR Quality readings went to poor, I am assuming it does work. I have noticed that when humidity is below 30% it fluctuates from 25~% to suddenly 35% 40% then back again to 25%.

Got this meter for our living space as we have a couple kids and wanted to see how good the air quality was in the area. The meter goes through a calibration sequence, then stays running as long as the battery is charged. We've noticed (as we expected) that our air quality is good, and we didn't need to make any changes to our living area. However, whenever we'd open the door and a draft would come in, or we'd be burning a candle, the air quality would drop and the meter would point this out (goes from good to ok to poor).Battery life is fine (I'd say about 1 day), but we've connected ours to a battery bank and it'll run for a week on a charge before needing to be recharged. If you had an outlet near by, you could also just plug in a phone style charger to keep this running constantly.Overall, it's a nifty device that gives us peace of mind.

With numerous tropical plants at home, maintaining the ideal humidity level is crucial. This tool has proven to be veey useful and aesthetically pleasing. I highly recommend it for effective humidity control.

TVOC AND HCHO READ LOW ABOUT 50% . WILL LET IT RUN FOR A COUPLE DAYS TO SEE IF THE READINGS WOULD IMPROVE BEFORE RETURNING.

Now I know my indoor CO2 concentration and VOC level with this product. Also provides info whether the air quality is ok or not. Display is nice and clear.

The media could not be loaded.  Product came beautifully packaged and was ready to go right out of the box. No need to charge or connect an app. Just hit the power button and it gets to work reading your air quality. It small enough to fit anywhere or travel along with you.Over the years I have replaced windows and sealed up my house to make it more energy efficient. It also made the carbon dioxide and other levels go up. For the price of having a HVAC expert come in and monitor for a week I was able to purchase this unit and monitor myself. Now I know if I need to open some windows or run some fans.

Nice Little Air Monitor. It seems to be fairly on point. I haven't tested everything on it but Temp Close. I really like the Lighting on it. Its built better than most.
