IQAir Air Quality Monitor [PM2.5 Particulate Matter, CO2 Meter, AQI, Temperature, Humidity], Smart Air Quality Meter [Wi-Fi, WLAN, App, 5” Display (12.7 cm)]

I was worried for my newborn this helped me alot

Purchased this monitor to pair up with my outdoor air monitoring system. Connection to my AirVisual app took two attempts, but worked. I like the feature to view my outdoor air quality on the left side of the the large screen. This gives me a direct comparison between my indoor and outdoor air quality. The unit is quiet enough to use in the bedroom. The screen can be turned on and off with a press of the button. The app integration is nice and shows historic data from the monitor by hour, day and month. Best monitor I have used so far.

The product's quality was extremely poor. Within the first month of use, it stopped working, so I sent it back to the company for a replacement. Instead of providing a new product, they simply fixed the issue and sent it back to me. It worked properly for about two months, and then it stopped working again. I highly recommend against purchasing products from this company. The after-sales service is terrible, and they are unfortunately promoting a product from Switzerland.

Trovo questo dispositivo davvero utile. Lo utilizzo prima di uscire per una corsa al parco per sapere come va la qualità dell'aria. Inoltre, lo uso per capire quando devo aprire le finestre e ventilare l'appartamento (CO2 elevato). Non do 5 stelle perché utilizza ancora la datata porta micro-USB invece della più moderna e pratica USB Type-C.

Wir verwenden den AirVisual Pro nun schon über ein halbes Jahr. Als Allergikerin ist es praktisch zu sehen, wann die Pollenbelastung nach dem Lüften steigt, bzw wann man besser das Fenster geschlossen hält (sofern man einen Messer für Draussen auch hat) Die zugehörige App ist ebenfalls praktisch. Hier kann man die Daten ebenfalls abrufen und die Veränderung über die Tage hinweg anzeigen oder die Einstellungen am Gerät über Wlan verändern. Praktisch ist auch die CO2 Anzeige. Denn manchmal merkt man vielleicht noch garnicht, dass es mal Zeit wäre mal kurz die Fenster zu öffnen. Das Display kann in Helligkeit reguliert werden und man kann einstellen, dass es nur gewisse Zeiten am Tag eingeschaltet ist. So kann man auch Strom sparen, wenn man nicht zu Hause ist. Der Akku hält auch super. Wir schalten zB in der Nacht die Stromleiste aus an der das Gerät steckt, aber es misst dank Akku trotzdem weiter die Luftqualität.

I’ve been getting worried about the increase in vehicle traffic on the major roads near my house and also on my own street. I have noticed when I step out front, or back, I get a blast of car exhaust blowing toward me. There are many renters in one house, with several cars, usually idling, plus Ubers and deliveries. I have Dyson products in my house but I was concerned (more for my dogs!) that when they are outside, they are not inhaling all this pm 2.5! My government-air-quality station is a few kilometres from me and, sure, general AQ is nice to know, but where I am actually located can have much different AQ than that station obviously. What’s nice about this is I can put it on my deck while I am outside and see what the pm 2.5 levels are, and as soon as I bring it inside the pm 2.5 returns to zero again. I have tested this against my Dyson with the door open and it’s accurate. In fact IQAir was the most accurate in a comparison of consumer-grade AQ monitors, and for the price was surprisingly close to the accuracy of government monitors (within 5% I think). Anyway, I use this inside the house, and I have AQ OUTDOOR for permanent measurements outside (mounted on a front-yard tree) which I love even more. That one lets me know when is the best time to go outside. It’s so interesting seeing what the trends are, and how meteorological conditions and wind improve or worsen AQ. Both modules have continuous monitoring or by the hour. The app is great and instantaneous. Both store historical data which you can share on the iq air map. I’m really happy with IQair and my third product will be the Atem for the car. If I can afford another AQ Outdoor for the deck I will get one. (You don’t want to open your windows when AQ is bad, and your nose can’t always tell). Where I live it’s just cars and cars and I want to be conscious of having clean air for my pups to enjoy, and it benefits me too.

This is super-accurate for PM2.5 and CO2! Easy to use! I don't write a lot of reviews but I just had to. This is our 3rd since it was first released by the manufacturer (an excellent manufacturer of extremely high-end medical grade air filtration machines we have used for almost a decade). I used a different brand of air monitor before which was much harder to use and maybe a bit less accurate. It also connects to see a worldwide network of readings that I can see on a map and use to assess real time air quality in another neighborhood to decide to go there or not - great during the CA fire season when you have asthma! Downside is just that it does not measure some things: PM10, PM1 or smaller, VOCs, ozone. I generally find that under normal conditions PM2.5 gives me a general feel of the dust levels in the air, but of course some things can slip through that measurement size. Of all of those additional measurement abilities I'd most want a VOC meter added. The discontinued air monitor I used to use also had a VOC meter and I did find that useful. Sometimes I feel nauseous or get headaches due to high VOCs. Sometimes the CO2 also rises when the VOCs rise (because it's due to not enough ventilation/fresh air coming in), but not always. So being able to detect times of low CO2 but high VOCs was helpful for assessing the health of the indoor environment and changing things to lower the VOCs. I thought this was going to be a huge disadvantage, though, and it turns out to only be relevant in rare situations, because the CO2 almost always tracks with VOCs anyways, so CO2 serves as a proxy for VOCs just fine most of the time. Overall, I love this thing! Love it's clear display, accuracy, and simplicity! I keep it on all the time, usually without pairing it since the screen is so clear even from across a room that I don't need it on my phone to see what it's telling me about my current air quality.

Displays a lot of very good information but the battery performance is very poor, hence the reason for three stars
