- BREATHE Airmonitor Plus Indoor Air Quality Monitor w/CO₂, PM & App. Gen 2.

This is a very useful device for my purposes— I have a small office area that I work in with poor ventilation and I was curious how bad the air quality was. I was very surprised to find that my CO2 levels were at a very concerning 4,500— they are supposed to be around 400. The monitor immediately identified it as unhealthy and that prompted me to immediately open my windows and cut my fans on to circulate air. As soon as I did that, the numbers began to rapidly decrease until they finally got back down to 405 or so (Good/Healthy). Problem is, as soon as I close them and begin to hang around, they creep right back up pretty rapidly— but at least the monitor shows this is the case very clearly for me. I know these readings are legit because the CO2 numbers go down immediately after I open windows or get fresh air in— and further, when I am in the room (like overnight) they increase substantially and progressively— but during the day while I am out of the office all day and return, it is still in the low 400’s. So it’s definitely me increasing the CO2 levels and that proves to me it’s not just some random made up measurements. The other particulates are very low here probably due to me having a high quality HEPA filter always running, so that doesn’t surprise me but lines up with what I’d expect to be accurate. But when I open the windows and my neighbor down the road is burning some debris or something or someone has a fire nearby or there’s pollen etc- those particulates immediately shoot up as soon as I let the outside in. So I’m convinced it’s a legit product and measurements are real based on those evidences. That is all useful info that I can apply to help with my health. Everything is easy on the unit, but the one difficulty I had (like so many others) was getting the darn unit to connect to the app and wifi. I tried sooo many times— and I’m a network engineer, so I know what I’m doing. Here is a tip: the only way I was finally able to get it to connect was I had to unplug it and completely drain the battery dead, then hold the power button for 10 seconds as I plugged it back in and it came back on (to set it into pairing mode)— the time I did that it worked immediately and perfectly. Hope that helps someone with this same problem. Shouldn’t be that way but I think that’s the fix. The only other issue I have with this product is the display is freakin BRIGHT- you don’t want this thing in your bedroom while you’re sleeping, trust me. You can dim the brightness using the app (once you can finally get it to connect and pair, otherwise you’re doomed)… but I’d rather use the proximity sensor to cut the screen off when I’m away or not moving/near— that’s a clearly advertised feature. Unfortunately, this feature does not seem to work. It’s set in the app to cut the display off when I’m not near, but it never does. Have adjusted time limits, cut it on and see… cut it off and see… tried it on AC power and on battery, restarted everything— nothing works so far. Very disappointed in that because I have to put it in my drawer at night or cut it off so my room is not like a midsummer day; which is a bummer since it’s supposed to be able to cut the display off via the proximity sensor. Best I can do is crank the brightness level way down, but then I can hardly see it during the day- so please fix that bug. Other than that, it seems to be accurate as far as I can tell and the temp and humidity sensors are within a few percent/degrees of my 2 other meters so— truth is I’m not sure which, if any of them are accurate, but they’re all “close enough” for my purposes. I’m not running a science lab or anything where I need .00001 precision there. Anyhow. Unit is cool, battery life is very short- only a few hours- but I don’t really use it off the AC anyhow, so no biggie for me. Would like all the features to work a bit better and the app fleshed out a little more (widen the alarm thresholds, they’re very limited… and make the active screen on the app match what’s on the unit, or save the last one you had it on- I hate having to select CO2 every single time I go to view— I am never really interested in PPM or VOC levels but it always starts on the same screen no matter what you’ve set it to on the unit or in the app last. Super easy to do a “default initial screen”… but it works for what most people are interested in. I could recommend it as a useful tool if your air quality is in question and you want to be able to have a way to monitor and get quantitative data to be able to act on. UPDATE: I wanted to come back and give this company its due kudos. It turns out that the dim function does work-- but the light sensor in my first unit was just bad. I contacted support about the issue and the fellow was very helpful and they replaced the unit for me without a bunch of runaround, which I really appreciated. I've been using it for a good while now and it's still working and doing great. They updated the app a while back, and my overall opinion of this product and the company now gives it an extra +1 for the excellent support response. I am taking it from 4 stars to 5, as my remaining complaints are relatively petty. The only thing I wish it had was HomeKit support so I could integrate it with Apple Home, but it's not a huge deal. Overall, I can recommend the product to anyone interested.

This air quality monitor is very responsive and quickly detects changes in the surrounding environment. The readings update noticeably when conditions change, which gives me confidence that it is actively monitoring the air. It is easy to use, easy to read, and has been a helpful addition to our home.

Honest feedback both pros and cons: I like that the device is small in size with a sleek design and has many different sensors! I also like that the screen goes into energy savings mode which turns off the screen when motion in proximity is not detected. This is a really nice feature to save energy and also the screen should last longer and not get burnt out meaning your investment will last longer! Its small size and detachable USB makes it easily portable. I do not think it is meant to be a portable unit as the battery life is only 4 hours. I did test this and without WIFI the battery lasted me 3 hours and 55 minutes. It would be really cool it the device had More battery to be more portable and versatile. Then for example You could go in a shed with no outlet to maybe do some work like carpentry and monitor air quality while working. You can still do this but only get 4 hours max with a fully charged device. I wish the device had bluetooth…. I do not have wifi and many people do not have wifi like cabins and RV’s and campers etc. If the device had bluetooth connectivity i would be able to use the app but without the app the device is more limited in function and acts as a stand alone unit at a glance (this is probably not an issue for most but it is for me). It would also be nice if the device had AQI to factor all metrics into one overall score and let you know the quality of your air. Each measurable is color coded and often i am in the green except for like 1 criteria. Not having AQI is not a deal breaker as i really just wanted it to be able to view various levels and am able to do so manually which does not bother me at all. I also wish the manual had more info suck as types of sensors used and their accuracy tolerances. This is something i thing should definitely be communicated in a manual. In addition having some more detail in the manual about the various metrics and what they mean and how they are measured would be nice. Including some detail about what these metrics mean and safety levels would also be nice so that you do not have to google for example what TVOCs are and what levels are considered harmful. I am unhappy because this device does not match readings on my other air quality monitor from a different brand which cost the same amount. Now that does not necessarily mean that that this device is inaccurate. However 1 of the 2 devices if not both are inaccurate and it is frustrating not knowing which device is reading correctly. One device has 2.0+ reading of TVOC which is harmful and the Breathe shows .2 as for the HCHO my other device shows .2 and breathe shows 0. I would have to buy more devices to compare and i am not rich so that is not something I can afford. I am hoping the accuracy can somehow be tested without too much hassle. The customer service is good as the Breathe team does respond to emails typically within 3 days. I am still communicating with their customer service regarding the accuracy of this device. Overall I am satisfied with the device! I would be really really satisfied if i can confirm the accuracy which would earn my trust and confidence in the brand. If Breathe keeps its small size and takes some of these suggestions to make a “version 2”. I would definitely buy it!!!

Even though it is the best designed product among its peers, it is hard to use it. First of all, you need wifi to connect to device. You cannot connect via bluetooth. Therefore, If you want to use it at your office and your office does not provide wifi (for security concerns) like mine, using this device near impossible. You cannot even silent the divice (and it has really high volume in default). Every time it close itself, all the settings you have done goes to the default. Additionly, if you are using 5 ghrtz wifi, it does not support. You need to use 2.4 ghrtz in order to use it. Sevondly, battery life of the item is really short. After charging over night, it's closed in an hour since its battery drained. Additionly, the battery percentage on the device screen and on the app does not match. I literally do not know which one is correct. I couldn't compare the air quality metrics if they are accurate since I do not have other product for the same purpouse at the moment, but the thermometer and humidity does not give the same value as Xiomi thermometer and humidity sensors. The worst part is, I wanted to return the product. Amazon accepted the return but didn't give the return number for me to sent it back. Customer services said that I can return it with any carrier of my choice but I need to pay the return fee myself first. Then they said Amazon will pay me back but they cannot explain how. I spoke to the several carrier firms in Turkey to return the item but minimum fee for the product's return from Turkey to the Las Vegas Amazon storage is 100$. I do not have additional 100$ just to return the item back. I am not even sure when the return fee will paid back to me ( or if ) even if I can spare the money to return it. I spoke with two different costumer services agents but I couldn't find any solution. Unfortunately, this is the worst experience I ever faced with Amazon over the years. I really do not recommend buying this product, since you cannot practically return it if you do not like it. I am literally so sorry that I wasted my money to the product that is not mature enough to be used by customers, especially in that price range. And I cannot even return it.

This is a genuinely impressive piece of tech for the price. Tracking PM1/2.5/10, CO2, TVOC, HCHO, temperature, and humidity all in one sleek display gives real insight into indoor air quality that most budget monitors can't match. The screen is clear and easy to read at a glance. For anyone concerned about allergies, air pollution, or just overall home comfort, this device delivers professional-level monitoring at a fraction of what comparable smart monitors cost. Excellent value for the features packed in.

I just got the Breathe Air Monitor today. And first off, just want to say thank you so very much for having it at such a great price, that is much appreciated. It arrived in perfect condition. I wanted something that had good reviews and that would also be accurate. I have an Amazon Air Monitor already but i wanted an extra monitor just to be sure of the readings. I already have 2 medical grade air purifiers that i purchased from Amazon, so i am sure that is probably why my readings are so low. My other monitors also show low readings too so i know that this is accurate. I worried a little at first seeing that the PM1, PM2.5 and PM10 all kept saying zero, but i guess that is a good thing to have low or no readings. The CO2 was giving me a number reading so i know it was working ok, but finally got the PM readings to show 1 and then go back to zero. I think my 2 air purifiers i have running plus i vacuum every day to keep the dust and dirt down, is helping since all the readings are so low. But with the wildfires that were going on all around me, plus a neighbor that smokes next door and then the 4th of July fireworks, which really set off my monitors and purifiers. So the combination of purifier and monitor work together very nicely. My Alexa keeps reminding me that i have excellent air quality, and i want to keep it that way. Keeping a monitor and watching out for your air, this is the best thing i have ever done. I did not know that was probably the reason why i had to use nasal spray and allergy medication all the time. But since being a clean neat person to keep the dust and dirt down, it has really made a difference and i think everyone should really buy these monitors to keep track and know their air quality. All i know is that i feel so much better and alive now than i ever have and being able to breathe is just amazing and sleeping good too. There really is no noise to this unless you have one of the alarms going off on your air quality, but that is a good thing, but also, you can mute the sound too, but i prefer to know when my air quality is bad so i can make the proper adjustments. I think i probably am the only person here in my town who has the best home air quality right now, and is really good to have this monitor to let you know. I will end my review with just saying.........Thank you Breathe Store. Ps. I am posting a few pictures to show where i put my Breathe monitor and the readings on it. Also, it was easy to add internet wifi, the app is fantastic and easy to understand. UPDATE---After having this monitor for a few days now, i think it drives me more crazy trying to fix my air quality, but it started telling me to open a door or window and let air circulate, poor ventilation. Which, after i do this, the C02 reading does go pack down, but opening a window and door also increase the PM1, PM2.5, PM10 and VOC numbers, not too much, but enough. However, with the heatwave currently on and it being close to 100, opening a door and window helps, but you also get hot doing this. My CO2 numbers are starting to spike and was surprised at the 800 CO2, but as soon as i turn on the kitchen vent and open the door and window screen, the numbers do go back down. But when you close your door again and turn on your air conditioner, the numbers go back up. So it kind of drives a person crazy trying to figure this all out. My living room is being monitored by another air device and CO2 is fine, it is just my kitchen area. I guess i have to pick and choose my battles. But i know at least the device is working and doing something. Accurate or false reading, who knows, but at least it alerts me to a potential problem.

Amazing just allow us yo set alerts on the other metrics

Works great. Finally know what's actually in my air. App is simple and syncs instantly. Battery easily gets me through the day. Would buy again in a heartbeat.

On the pro, the temperature data seems to match my other sensors, not quite sure about the rest. On the cons: The app does not allow you to see all the measures over the day. The WiFi keeps disconnecting. I bought it as I thought I could export the 15 min data but all the data is aggregated daily. In short, it is not a good product.

Love all the readings that this monitor can do! It also looks great! Not as ugly as other monitors. I testing the TVOC & formaldehydes by opening alcohol near the sensor and it did detect. The app works great & the data export feature is really convenient for me to review in excel. I love the graphs in the app too. I was feeling tired in my home and this monitor helped me realize I had high CO2 levels in here. It also made me realize I had high humidity at over 60% which is why my place felt stuffy and my floors were getting soft. I bought 4 dehumidifiers immediately.

Good product. Easy to use. Compact size. Just as expected.

This stopped working properly after about 10 days - recording erroneous carbon dioxide levels of over 3000 inside and similar readings when tested by recording outside so do not purchase. Amazon would not accept it for a refund through returns

Got it the other day, So far seems pretty good we painted the other day so I know the TVOC would be a little higher than normal and it’s showing that so seems to be working good. Happy with my purchase
