Tested this little gadget in multiple situations, outside and inside. I like the fact that when I placed it on top of my air purifier, the reading went down to 0. It is consistent with other measurements, so I feel it is very accurate. The phone app is nice, though I wish it had notifications.
The compact design is very good and it is easy to install and use.
*Comes with charger cable;
*Directions are easy to follow;
*Intuitive to use;
*Gives a lot of useful information, including not only air quality but also things like temperature;
*Small and portable
*Easy to read interface.
Works! Even detected BBQ and other fumes from outside.
It’s a simple device, easy to set up and use. The app helps keep track of air quality history. The LED display easily tells the air quality level. Overall, I think it’s worth it.
Super cool little gadget. Whether you have health problems or just want to stay on top of the air you are breathing, this is a great option. I don’t have much experience with this type of machinery but from what I’ve read this is a lower priced entry level type of device. There are other more accurate models that cost several hundred dollars but are only marginally more accurate. Sounds like unless you need it for some scientific purpose this is more than enough for standard home/office/car monitoring. The unit is pretty much plug and play. You turn it on it and monitors the levels or particulate matter in the air + current temperature and humidity. This measures the particulate matter by size. So PM 1.0 are very small super microscopic particles that are not filtered by standard HEPA filters or N95 masks, The PM 2.5 is where you get into the virus and smoke levels that a HEPA filter or N95 would contain and PM 10.0 are larger particles that are definitely filterable but could still cause harm or irritation to your respiratory system. The unit glows Green, Orange or Red to indicate current air quality. This makes it really easy to get an idea of the air quality from a glace across the room without getting actual number readings. It comes with an app that allows you to keep track of your current and past air quality to look for trends. You can also log what room you have the device in so you can keep track of things based on location as well. Powered by standard USB cable and has a built-in rechargeable lithium battery. I’ve found you really need to leave the unit plugged in for ongoing monitoring. The battery goes pretty quick when its not hooked up. Instructions mention to be careful with cube so you don’t mess up the sensitive monitoring equipment. I’ll say that I’ve dropped mine on the concrete twice pretty hard and it don’t see any decline in function. That said, I don’t suggest trying to drop yours but you can feel good that if it does happen at some point you’ll probably be okay. Solid 5 stars on this item!
I have friends and family that have respiratory issues like asthma, so an air quality monitor like this is very useful to me. I don't really know how it works or how accurate it is in detecting the air quality, but if it does what it says it does, it's priceless. The temperature and humidity seems to be correct.
The item itself seems to be solidly built. It looks pretty cool. The glowing green light makes my room look futuristic. The screen is also bright and easy to read. Also, It's really light; it's about the same size as one of those small portable BT speakers. I plan on carrying this in my car and test it out in different environments.
I would recommend this item. It's a nifty little gadget.
I was looking for a reliable pm 2.5 censor at a reasonable price. For those that can connect to WiFi, it usually costs about $150+. The reading is consistent and reliable, as I compared to my AtmoTube. Happy with it so far.
I was skeptical but this works like a charm. As the air quality gets worse the numbers will climb on the display which can also be seen in the app which is actually decent. I’m also able to view the air quality of wherever I place the sensor remotely. In addition to the readings on the display, the backlight color will change from green to orange and then red as the air quality changes for quick identification. I was able to test this out after doing some wood working as the house . As the room got dustier from the saw dish and power tools, the sensor changed and rose through all three levels all the way to 98 and red. I recommend having something like this around the house to be aware of what you’re breathing. This comes with a power cord but also has a batter and can be used without being plugged in.
I bought the device seven months ago. The device is quite useful these days because of the wildfire in California. I constantly checked the air quality indoors. I read other reviewers and agree that the mobile APP is not very useful. I forgot how I set it up so I cannot comment on how difficult the setup process was. But in terms of accuracy, I am quite satisfied because the PM reading correlates very well with my experience. I place the device not too far from the kitchen, so the readings fluctuate quite a bit when we are cooking and done. I also think the temperature and humidity readings are accurate (they correlate well with another temperature and humidity measuring device), though I hope the readings are larger on the display. I also like that the device uses USB power so I can power it with a portable power bank when occasionally camping outdoors.
