Temtop Indoor Air Quality Meters PM2.5 AQI Air Quality Monitor Home Air Testing Kit, P10

my review is for M10i [monitors AQI, PM2.5, HCOC, TVOC (with WiFi)]This meter helped me provide critical data to my landlord, doctors, city about a difficult situation where my neighbors' illicit activity severely impacted my health, but was otherwise difficult to quantify and verify. It's been invaluable.I use Temtop's app on an iPhone, and have used three different WiFi setups.I 100% recommend reaching out to the manufacturer's team when you encounter difficulty connecting, they have been exceptionally helpful, and wow, I ended up with a lot of questions, and they have been consistently wonderful in helping me find the solutions I desperately needed.It can take time to attach this meter to WiFi, but here is what I learned:• have all your phone's permissions set allow the Temtop app to do what it needs to do• have set your WiFi network & router permissions set allow this meter to connect to your 2.4 GHz WiFi• Use 2.4 GHz WiFi, not 5 GHz WiFi. Temporarily hide or disable everything except 2.4 GHz. Call your ISP for help if needed, and permanently blended WiFi routers won't work.• Temtop's amazing support folks recommended that I temporarily disable all but one of my mesh routers on my network while I connected my meter to my WiFi. This worked! Meter automatically re-connects to WiFi after either meter or router are restarted.Temtop's app exports the M10i meter's numerical data as an excel spreadsheet if you ask it to :)The most frequent output is 1 reading per minute. The app's graphs are wonderful and you can zoom in to time/amplitude easily.It's a very helpful and cost-efficient meter, and has made my life significantly safer, given the situation I needed to be able to monitor.

For some time, I have been wanting to collect baseline readings for the air quality in my home. More specifically, I had the desire to collect air quality values for my ceramics studio. As it is in somewhat of a confined space in the basement of a 94-year-old home, air particulates and overall air quality are my main concerns.It was quite difficult shopping for an air monitor that seemed reliable, collected values I was trying to discover, and one that was not incredibly expensive. Throughout the days spent browsing and doing a fair amount of research, I passed on the Temtop M10 several times. However, it continued to be the option I returned to.Two attributes I wasn't satisfied with include:- the lack of being able to display the concentration of specific particulate matter size, less than 2.5 microns.- the above information would only satisfy my own curiosity at this level of monitoring.- the anticipated lifespan of the HCHO, TVOC and PM2.5 sensors.- if I truly need more than 3 years of monitoring, I'll cross that bridge when it comes.The product arrived in two days, and was packaged in a nice, rigid box. Along with the monitor, the box contained an instruction booklet, a ~40-inch power/charging cord (you'll need a wall outlet adapter), and a reset pin. There are specific calibration and acclimation directions, but I don't want to leave the monitor outside in this frigid cold for six hours. The claim is that leaving the device outdoors/indoors, in a well ventilated area, aids in the initial calibration.Here are steps I've taken, instead, and a few things I've noticed:- upon arrival, I took advantage of the monitor's full charge and placed it outside for one hour.- while outside, I gathered some AQI data, specific to my zip code.- the above information was used for comparison with the M10's measurements.- after an hour in single-digit temperatures, the monitor was still fully charged.- cycling through the four displays, I was surprised by the accurate readings.- the readings were within a threshold of accuracy which made me comfortable enough to bring the monitor inside.- for the first six days, I will leave the monitor outdoors (conditions permitting) for one hour.- in my mind, doing this will allow me to track the monitor's measurements, and gain more confidence in its accuracy over time.- as the seasons change, I will send the monitor outdoors, and recalibrate the HCHO sensor.As I have only had possession of the M10 for three days, I speak with limited experience. It has been positive, thus far. The M10's display is bright, and easy to read. The sensors are quite sensitive to fluctuations within the monitored environment, and seem to be accurate enough to trust as a basic gauge for collecting data. The battery life is decent enough for my needs. My preference is to leave the M10 plugged in. I currently have no other devices for measuring the air quality in my home and studio. I do have CO/smoke/gas detectors and a hygrometer, but nothing to compare to the M10. There are no purification systems present in my home or studio other than the furnace and air conditioner. The Temtop M10 is my first air quality monitor.If you are searching for an affordable device to use for gathering some basic information, I'd say the M10 is a solid candidate. This is especially true if your desire is to collect air quality values, with the need to escalate your response/air purification being in question. It may help put your mind at ease, or provide information valuable enough to make future decisions revolving around mitigation.

I have chronic rhinitis. In the mornings I spend a couple of hours wiping my nose until cetirizine kicks in. I filled my house here in Southern Arizona with hepa filters and bought this to monitor the air quality.Here is what you have to remember. This device measures the concentration of 2.5 micron particles in your room air. That may or may not be the cause of rhinitis. I have a neighbor that burns wood to heat her house here. There is a fairly unsound way of heating a house when the temperature is not even freezing and it does send this device into spasms if we open a door, but it does not make me sneeze more. I'd still like her to buy a decent gas pack for her HVAC system.I calibrated it for 6 hours by placing it in the exhaust of one of my hepa filters and now get 2 -3 reading when everything is calm. If I cook, then it can go up to 150 or more. I still do not get a runny nose.My wife just walked into the room with some kind of citrus spray on her body and my nose opened up like a sewage outlet. The device still showed a 3.So. I conclude there is no correlation between the reading on this device and the state of my nose. If you want a device that measures 0.25 micron particles then this is the device for you. If you want to understand your rhinitis problem, then no.
