Roroperon: eu já tinha um Arno de mesa e já gostava muito por ser eficiente e silencioso. Este que comprei agora em nada deixou a desejar. Muito silencioso também. Estou amando o produto e economizando na minha conta de luz.

Luizete nobre: The media could not be loaded.  Gostei bastante do ventilador, ele além de de ser dois em um, pois vem com base que pode ser adaptada para ventilador de chão. Ventila bastante, estamos passando por uma onda de calor com Rio de Janeiro e ele ajudou a refrescar o ambiente… comprei outros com certeza. O único ponto negativo é a base dele que achei um pouco torta… montei direitinho conforme o manual, mas quando liga ele no modo mais forte ele desentorta, enfim… o mais importante é que ele ventila bem!

PJJ: My small condo is closed up (very hot in Florida for a while), wondered it I was getting enough fresh air, plus I share with a tenant who has asthma. So I wanted to check CO2 and particles etc. The CO2 was 538 which is good safe level. It was fun that when I breathed very gently on it, from a few inches away, and CO2 shot up to 1700+ momentarily, then went back when I stopped breathing on it. I was surprised it was so sensitive and reacted so fast to my breath. I guess I output a lot of CO2!

Jimmy Taylor: WORKS PERFECTLY - GREAT AS AIR QUALITY MONITOR.
This is a 3 month review. I have not had any issues or problems with this meter, it has worked flawlessly. Just plug it in and give it a minute or two to analyze your air quality. The display is bright and easily seen in color. The stand is a great convince because you can walk by and see your results easily. It also seems to take an average of all the parameters analyzed and highlights a specific environment rating at the bottom. It is also an advantage being able to make it very portable to take it from room to room, basement, garage, or other person’s home to analyze their air quality. Also is great to take with you if you rent an AirB&B place or hotel/motel room to check the air there, even for mold. It also allows you to further calibrate it if needed by taking it outside and perform a calibration as a baseline to compare it to inside air quality (assuming your outside air quality is good at the moment). Personally I found it enlightening that the CO2 levels increase substantially when cooking with gas stoves / ovens for prolonged times, sometimes reaching levels that have to concern you & your family’s health. It...

TyTy: Value, it has that in spades. From a lower price compared to similar products, having multiple important sensors; Namely TVOC sensor was important to me, after having discovered mold in the storage room under the stairs (the landlord about as eager to send someone to deal with it as a slug is to salt) I figured having something like this for tracking its return, after deep cleaning the whole area, would be a good idea.

I'm also excited to have this on hand during the fire season, for anyone likewise in a fire area curious of pm2.5 and pm10 levels this thing is a welcome tool.

Clear and easy to read, I wasn't surprised by elevated levels of c02 and TVOC from what I already know of this old building. But I was happy to see they were at least in a safer range then I had suspected and that is going to help me sleep at night. And that's the main reason to have this right? Peace of mind at one heck of a good value!

Edit: Update on this thing with the classic wild fires in the northwest. This thing was a trooper at getting me more up to date information on air quality throughout the fires. Found being slightly down hill of the valley winded up having ppm densities...

Engineer_Brian: There's a lot of good in this product and there are some definite user trap and limitations that could be improved.

Pros:
- Live readings appear accurate and adjust to the environment
- Clear indication of mean values being important
- Like that it can be USB plugged on the side while using and battery life lasts a long time

Cons:
- Manual and UI usability are a challenge to understand
- Clear button doesn't clear Mean data, reboot does this.
- no indication of how long the mean data collects data (does it restart after an hour, 2 hours, until clear or a reboot)
- manual has lots of grammatical errors.

Suggested Enhancements:
- Change the Live Values readouts, so that the "Switch" changes them between Live, Mean and Peak value. This means you can remove the Mean Value lower on the device.

- Clear button should clear all past data, including Mean. This way I can switch rooms, hold the clear and start collecting all new data.

- Add Peak Value. Many times I want to see the worse case that occurred, not just the mean over the hours of collecting.

- I like the color coding of Green, Yellow, Red. It would be nice on the...
