LifeBasis Air Quality Monitor Indoor, 10-in-1 Air Quality Detector with Stand, Real-Time Air Meter Test AQI, PM1.0, PM2.5, PM10, CO2, TVOC, HCHO, Particles, Temperature and Humidity with Alert -White

I purchased this Air Quality Monitor to determine if we have good-quality air in our house after the recent HVAC work, and I have been impressed with the amount of information it provides in such a compact device. It tracks everything from CO2 and PM levels to temperature and humidity, all displayed clearly on a bright LCD screen. I love that the color-coded indicators and alarms make it super easy to know when the air quality dips, one of my favorite features of this device. The sensors seem accurate and respond quickly, which gives me peace of mind, especially when cooking or spending time in the basement. The built-in rechargeable battery is great as It is less maintenance work to just plug the monitor. The USB-C charging is awesome, as I don't have to keep track of specific cords. It’s lightweight and portable. I can walk around with it in the house or garage to test, and it can easily fit in my pocket. Overall, this monitor has really helped me stay aware of my indoor environment, and I would definitely recommend it for anyone wanting to improve their home’s air quality.

I wrote this item for my parents when I took away their old weather station and gave them an Amazon echo show eight instead. They like it for the camera and for some features, but they really just missed having the humidity and the interior temperature showing at all times on the screen so I got them this unit since I did not need to put a device in my window or outside for it to tell the outside temperature. This is also an air quality monitor, which was an incredible bonus! I have nothing but appreciation for the device except for a rather Sterling, and then funny scare as soon as I turned it on. All of a sudden, the carbon monoxide levels went to at least triple what is acceptable and there was a an alarm beeping that did not want to stop. Of course I did not read the instructions prior to using it the first time; who ever does that? Lol 😆 The joke was a middle though, because it was later in the evening. My parents have gone to bed, and I was leaving or thought I was going to leave, and I got the scare of my month, thinking that the carbon monoxide was at a poisonous level. Indeed it was not, the unit does require to sit outside on a flat open surface for about 8 to 10 minutes before using it or getting any accurate carbon monoxide readings. Soon as I found that in the directions, I took the device outside turn it off turn it back on let it calibrate and ever since that date it’s been great! my other favorite factor about this particular air monitor is that it is wireless. There is a rechargeable battery, so sometimes you do need to plug it in to charge the battery, but not having to have it plugged in with an unsightly cord hanging off the edge of the table at all times is a huge plus for me! I have a $1100 Dyson air quality monitor/ purifier & the numbers on this device match up extremely close to what my Dyson says, so I trust that this is accurate. I will be getting at least one or two more for my own house.

This really is barely more than a toy. A real tool to do the job would cost many hundreds of dollars, but the documentation for this does claim it isn't laboratory test equipment. OTOH, it is cheap and can be nice looking. I have a combination of 6 different brand/model combinations and there is no consistency in any of the readings between any pair. Readings on any two usually differ by far more than 10% for any property. CO2 readings across all six brand/models I have might range from 400ppm to 660ppm when 400ppm is about the average CO2 level for non-polluted outside air between sea level to over a mile higher. Sometimes the readings for one property will stick at some vaue and not change but power off/on sometimes recovers it. One approach to using something like this is to buy a handful of models each from a different brand, Many sold on-line are exactly the same device sold as a different brand, if it looks the same it probably is. Instead of being concerned with the "reported" air-quality by any one device consider the average reading of some air-property from about four different devices. The most useful thing you could really get is a sign that some air property is increasing or decreasing in value over several minutes, you should be able to spot a trend in any property (especially if the trend is seen on multiple devices). The update rate is not fast, maybe one or two updates per-second but that's too short a time to determine anything useful about instantaneous air-quality given the true quality of the device, it's a shame they don't have an obvious rolling average type normalization to make changes less sharp and trends more obvious. For most users the best features to watch for in something like this is are probably rising trends in any of CO, CO2, PM2.5 and PM10 (most devices like this monitor CO2 but not CO). Use a proper home smoke/CO detector for actual personal home safety and leave the location if it's alarm sounds. But, with a device like this observing a rising trend in CO or CO2 might indicate a source of pollution from fuel burning indoors, ventilate, stop the fuel burning or leave. A rising trend in PM2.5/PM10 might indicate outside pollution from vehicles/wildfires (reduce ventilation or filter the indoor air but leave the location if CO or CO2 is also rising, especially if a home smoke/CO alarm sounds). That doesn't mean ignore properties like PM1.0, TVOCs and HCHO. You might live next to a source of any of them, but spray perfume or air-freshener will probably increase the PM1.0 reading. Don't sit staring at the device tracking the immediate trends. Turn it on placed in an unobstructed location. Look at it casually over a few days to get a feel for where the levels tend to be. Even get government data for outside air pollutant levels in your area for comparison. Continue looking at the device casually and a "trend would be that a number is far from normal and stays that way for many minutes. Especially if the same trend is seen on models from multiple brands. But, there might be time-of day trends, e.g. when nearby road traffic is busy. Since the documented sensitivity of any property ranges a long way between clean air and unhealthy air it's more likely any rising trend that doesn't set-off a home smoke/CO alarm indicates you might benefit from using simple air purifiers. If a trend like that happens on only one brand it's more likely the one device is innacurate and restarting it might help but stay cautious (the other three you didn't see a trend on might be the innacurate ones). Always trust a home smoke/CO detector and public service annoucements before one of these but it can help you make other choices that will let you clean your indoor air to a better quality than outside air.

Air quality sensor stopped working after a few months. Shows perfect air quality in a smoke filled room. Dangerous sense of security. Update: The company reached out to us, and shipped us a new AQ monitor that works great. Excellent customer service.
