BREATHE|Smart Portable Pollution & Air Quality Monitor, Measures Outdoor and Indoor Air Quality. Monitors Dust, Smoke, PM2.5 Air Pollution. Air Quality Tester - Reduce Your Exposure to Toxic Air

Let's list them: My Sharper Image OZONE based Air Cleaner, a Essential Oil Atomizer, Cooking, Vaporizer, Humidity from a shower..... For all of the Benign things it detects, I should just move out and leave it here to suffer. Then there is the silly dialogue that it continually displays makes it less of a scientific instrument and more of a toy. I am disappointed at best.

Not 100% convinced what it’s reading, I was looking for some measurement of indoor allergens, mould etc as my kids were constantly getting sick, this seems more suited to inner city pollution levels. I took it on a trip to China and that’s the first time I registered over 10, hitting 140 in some places. Nevertheless it obviously works but you’ll only need it if you think you need it

This was nicely packaged and super easy to get going - just plug in and go. We have good air quality, so it was hard to test in different areas. But it would go up by a few points as I moved through the house so I knew it was working. Glad to have this to ensure the air is safe for my family (especially since we are in a high fire risk zone so air quality can get really bad during/after fires in the area).

I bought this to test the air quality both inside and outside, as I live in an area where air quality can be compromised. The unit would not charge, so I sent it back for an exchange. The second unit was slightly better, but I returned it, as well. The home screen display never matched the description in the literature- no charging light displayed, etc. The charging station did not work at all for either unit. I could change the second unit I bought with the cord, but it didn't hold a charge more than a couple of hours, which made continuous monitoring impractical. The numeric air quality indicators were simplistic and did not give enough information to be useful, when I could get them to display. This is an expensive unit- don't waste your money!

Quit working after 4 months. Loved it until then.

I have COPD and air quality is very important in managing my life to accommodate my illness. I have found the Breathe monitor excellent although I am unable to verify its accuracy. However, it responds quickly to changes in pollution levels, whch I was able to verify during recent bushfires and smoke levels. I would certainlt recommend the device and would buy again.

Found when using room humidifier it displays extremely high pollution readings, apparently due to the humidity added to the air.

Ive had for a week now. Seems fine. Easy to use. Nicely designed. Im giving it a few more weeks of use and if its good, I may purchase another unit for my mother.
