Guardian Technologies Smart Air Quality Monitor, Displays PM 2.5 Levels, Humidity, Temperature Indoor and Outdoor and VOCs in Real Time, App Controlled, Alexa and Google Enabled, Black/White, AQM101

So this was an easy set up. Just plug it in. Once I downloaded the Aria app, and set it up with my home wi-fi, it said it needed to be updated. I tapped on update on the app, but it wouldn’t update. It takes about 100 seconds to update, appears to be updating, but then it still says an update is needed. It also comes with minimal instructions outside of how to set up the WiFi and pair it. There’s a manual scan and an automatic scan to pair it. The only 2 items that are available to choose from are a tower fan and something else, on the auto scan but after several tries it did finally let me choose the AQI to pair on auto scan . If your display is green then air quality is good, if it changes to orange, it’s fair, and red is poor. Here’s where my biggest complaint is. First of all the orange and red display are difficult to see, unless you’re really close to the unit. Second is that it goes from green, good air quality to orange or red in a nano second. And it does so everytime I spray anything in the room. Lysol, perfume, deodorant, etc, will make it go from good (green) to red in a heartbeat. My dog and cats jump on my bed a lot so I spray Lysol or fabric freshener on my bed linens often and that should not cause my Voc’s to go from good to poor. Lysol is supposed to clean the air , so why the unit reads it as dangerous is strange. I like that it gives you the relative humidity in the room as well as temperature but I’m not sure if I trust what I’m reading. My bedroom is the coldest in the house because I’ve got a portable AC in addition to my central AC in my room because of menopause I like to keep my room colder. But it always shows the temperature in my room at 73 to 74 but my thermostat in the house is always at 72, but you can feel a big difference in temperature from my bedroom to the rest of the house. There is one button on the front of the unit that once pressed it switches it from indoor to outdoor. Again, no way to check the accuracy unless I check the local weather logistics for my area . So a lot of “uncertains” with this unit. Can I believe what I’m reading? Don’t know unless I get another unit for comparison. I tend to Lean more towards it being less than accurate.
