Review: Nice design and well made - I've been using this in my home for a couple of weeks and it works very well for me. We have our windows open almost every day and I bought this to see how the air quality is when we have nearby wildfires. Luckily there haven't been any this year but when it does happen I will update my review. So far I have noticed that the AQI and ppm readings are low at night and go up as the wind picks up during the day. On the rare days we close the windows to run AC, the CO2 readings are higher. The screen is clear and has nice colors. There is an alarm function to alert you to poor air quality. It has an internal battery which seems to run the device for about day but it is designed to be plugged in most of the time.
Review: Proof these work: wildfire-caused purple AQI outside and monitor reading agrees - I got two of these monitors because I do pottery in my home basement and I wanted to be sure my air purifiers and pottery practices were keeping the house air safe. I have one in the basement and one the main living area in my house. The readings were always pretty low, ranging from 002-010, except for a couple of times when I kicked up a lot of dust. In those instances, the monitor reading was consistent with the indicators on the air purifiers, but still I was unsure how accurate they are. We are currently experiencing very poor air quality in my area due to distant wildfires. The weather app shows outside air AQI of 240 in my area. My indoor monitors were reading 35 and 24. I put a monitor outside and after several minutes it went up to 222 and had an audible signal. I took it back inside and it was reading 26. I replaced the HEPA filters in my air purifiers and after about 15 minutes, the readings went back to our baseline of 002. I replaced the filters in the basement air purifiers and again the reading on the basement monitor went down from 035 to 002 after about 20 minutes. I was pleased to see that the monitors work as intended, as do the air purifiers. The CO2 reading is not useful to me, and you have to recalibrate for CO2 every time you let the battery go flat, but for my purposes these monitors are great.

### ⭐⭐⭐⭐ Good quality, accurate

This is a good quality unit, except for one thing. The interface is awkward and it only uses military time
