IQAir Air Quality Monitor Indoor, Swiss Design, Professional Grade, Detects PM2.5, CO2, AQI, Temperature, Humidity, Indoor Air Quality Real-Time Air Quality & Forecasting, Historic Data

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.

It confuses me that high AQI (Red face) is not correlated with CO2. Your room can have high CO2 and still read low AQI. My machine kept saying that the AQI in my attic was zero, tho I had high concentrations of CO2. Many modern air quality detectors look at other facets of air quality, and I think that this monitor is missing some of those modern innovations. (E.g. HCOC, VOC, PM10). It’s AQI only reflects PM2.5 which makes you wonder why they report on both and not just PM2.5. It’s confusing. The UI is nice. I dont like that it uses a dated charging cable. At this price point I would expect USB-C which is today’s standard. It’s a good device if you only care about general air quality, but at this price I expected more value.

Well, I’ve had my IQAir AirVisual Pro for a few days now. And I just love it. It is mainly designed to be an indoor sensor, and that's how I'm using it. (You can actually use it outdoors, but then you don't get indoor readings.) You can monitor outdoor Air Quality by hooking it up to the internet. There are several local sensors that folks nearby me (just a couple of miles away) that are available, or there's the local Air District that is also just 2 miles away. All of these are available using the IQAir AirVisual App. The App is free, and you can monitor any number of Air Quality sensors worldwide that you want. I highly recommend the App just for those reasons. But where the Air Visual App really shines after you add the Air Visual Pro to the app. You can then monitor the outside Air Quality and inside air quality either on the app, or on the Air Visual Pro screen. It will tell you if the air quality is better inside or outside, and what actions to take, like open or shut windows, or don’t got outside, or outside activities are fine. The Air Visual Pro displays CO2 and PM2.5. It also shows the US AQI readings. China AQI is another option. The PM2.5 readings seem accurate, so I can use it to make decisions about closing up inside, and using air filters if needed. It’s really an amazing device. Also there is a significant Knowledge Base on the IQAir website that gives out a lot of extra information about the Air Visual Pro. The one drawback, is that it costs a bit, $269, but part of that cost is that is has its own screen. Having it's own screen makes it more usable, you can just look to see how the Air Quality is both inside and outside, and get the direct recommendations right one the device. It's a five star winner.

I got the unit, it seemed to work when I first got it, and after a while, I started displaying an indoor air quality that was perfect (0 PM2.5). I didn't pay attention to it too closely until we got some nearby fires and the air quality was actually 300+ (i.e. terrible and hazardous to breathe), but the unit still showed 0, perfect air. Tech support suggested cleaning the sensors, and once we established that the unit was indeed malfunctioning, because I only realized it wasn't working after the warranty was over, IQAir told me they wouldn't do anything to fix or replace it. So, it's a bad and unreliable product with a company that will not stand behind it. Shame, because it was otherwise beautiful with a nice interface, but that's worthless if it fails at the one job it has. The picture shows air quality from the internet and unit showing indoor pm2.5 of 0! You had one job.....

After having it for 24 hours I played with it this morning in bed because it has a long cord and there is a setting in there that is for the CO2 sensor and it was saying that the inside of my house where is basically full of smoke and unhealthy air and the little indicator wears a red face and I couldn’t understand it because I woke up feeling refreshed and so did the kitties so after playing with it I realize there’s a setting for a CO2 sensor that says if you just received this item which may have shipped and been banged around in a truck reset this setting only wants and it will re-calibrate my carbon dioxide are you acting as if you’re very weird go breathing in my area and close one bedroom apartment so after resetting it in a span reading truthfully now for about 15 hours and if we are comfortable and are 3 to 400 which is normal so all of the things are great I only bought this thing because after running numerous pepper and UBC filters throughout the house and one in Side A air handling for 30 million dog UVC bulb I purchased this for the cleanliness of the air Parrot a brand new, install, air conditioning system, which monitors the same thing with the ecobee wireless thermostat, professional grade, which also monitors VOCs and CO2 and they both concur. They are in agreement. That is why I bought it for a second opinion plus it’s connected to a worldwide sensor establishment that you get free outside air indications for where you are or where you may be heading. This thing is amazing. The AI confirms it that it is Swiss made to the highest standards including the VOC and CO2 Sensors. this is not some under $100 sensor that makes you feel good. This is a highly calibrated technical instrument that will tell you just how healthy your environment i.e. your home condo apartment van tent. It doesn’t matter. This thing will tell you if what your breathing is going to give you a healthy nights rest thank you for your attention to this matter.

I purchased the product about 18 months ago. It works very well. Easy to use. Accurate. Intuitive. Simple but useful. It's great. A few weeks ago, it started making an unholy racket every few minutes. It's very disruptive. I wrote an email to the company asking them for assistance. That's when the problems started. First, they take several days to respond to any email. Second, each email is redundant, as the person responding to my message hasn't read any of the previous messages. They've asked the same questions multiple times. Third, they say things like, "you should probably clean the bushings" without explaining what the bushings are, where they are located, how I find them, and how I should clean them. When I ask them for a schematic or an instructional video, they just say, "we don't have that." Finally, they said that I could send the unit to them (I pay postage), and they'll fix it FOR 65-75% OF THE COST OF A NEW UNIT! This is a top-of-the-line monitor. It broke in no time at all, and the company is absolutely not standing behind it's product. Avoid them. They're awful. UPDATE: I managed to find a reasonable person in the customer service department. This person initially gave me the same answers as everyone else (fix it yourself or pay us 65% of the purchase price to do it for you). When I reminded them that they've been giving them the runaround and showed them copies of the emails I've received (including ones that instructed me to fix a product that is different from the one I purchased and inquired about), this person offered to have the company fix the unit free of charge. You shouldn't have to jump through hurdles like this to get a company to stand behind their product, but I did, and they did, so take that additional information as you will.

I purchased the IQAIR monitor to track the air quality in my home and outside air as I often have the windows open throughout the day. After recent unforeseen fires in the area, I quickly realized how important air quality makes a difference in maintaining a healthy lifestyle. I own a home purification system, so the IQAIR device is a very compact, efficient and easy to use system that helps me identify pollutants in the air while complementing the purifier. The two systems work hand in hand with one another. Using this system, I am able to track real time data of temperature, humidity and C02 levels. This system is perfect for anyone to use no matter what age because of its color-coded display. It let's you know if the air quality is good, okay and bad. Not to mention, the set-up process was easy to follow along. The device connects to your home wifi and the application can be downloaded directly to your smartphone. The app stores the data while collecting real-time information so that you can go back and reference to previous recordings. I am Looking forward to purchasing this device for family members and friends. I would recommend this device for anyone dealing with respiratory or chronic health issues as it is a proactive way of staying on top of the air quality you breathe, which directly affects your health outcome.

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 was worried for my newborn this helped me alot

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.

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