BREATHE Airmonitor Plus: Smart Air Quality Monitor Indoor - 8-in-1 CO2 Meter, Formaldehyde Detector, VOC Meter, PM1/2.5/10, Temperature & Humidity - Air Quality Tester for Home with App

My air quality monitor monitors PM1, PM2.5, PM10, CO2, TVOC and HCHO. what do those values represent and why are they important?Great question! Your air quality monitor is measuring key pollutants that affect both health and environmental conditions. Here’s what each of those values represents:PM1, PM2.5, PM10 (Particulate Matter): These refer to airborne particles of different sizes—PM1 being the smallest and PM10 being the largest. PM2.5 is particularly concerning because these tiny particles can penetrate deep into the lungs and even enter the bloodstream, increasing risks of respiratory and cardiovascular diseases. PM10 includes dust and pollen, which can irritate the respiratory system.CO₂ (Carbon Dioxide): While CO₂ itself isn’t a pollutant at typical indoor levels, excessive concentrations can indicate poor ventilation and lead to symptoms like headaches, drowsiness, and reduced cognitive function.TVOC (Total Volatile Organic Compounds): These are gases emitted by various household items like paints, cleaning supplies, and furniture. High levels can lead to eye, nose, and throat irritation, and prolonged exposure has been linked to more serious health effects.HCHO (Formaldehyde): A specific VOC, formaldehyde is commonly found in building materials and furniture. It’s a known carcinogen and can cause irritation of the skin, eyes, nose, and throat.The monitor has been very responsive. My apartment lacks ventilation and the CO2 reads high when the windows are closed too long, so it is a good reminder. My daughter was not meaning to test it, but when she lit some incense the PM levels quickly went high as they should.The ap is great and you can set the levels at which you want CO2 and PM2.5 alarms set to it, you can export data. as well as other settings.

I'm very happy with this unit! It tracks all the key environmental metrics I wanted, has WiFi support, and even integrates seamlessly with Home Assistant. It looks great too.My first unit started behaving oddly, but customer service was very responsive. After confirming it was defective, they quickly sent out a replacement—fast and hassle-free. A+ for support!The companion app works well on my Android phone and alerts me when CO₂ levels are too high—great for knowing when to open a window. Integration with Home Assistant is the real game-changer for me.I also own several sensors from other brands, and the readings from the Breathe monitor match up well with them, so I trust its accuracy. Highly recommended!

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.

The Breathe Airmonitor Plus 8-in-1 Indoor Air Quality Monitor has brought me so much ease of mind knowing that anything harmful to my health is monitored and with the Breathe Tech app, having that information relayed to my phone that notifies me the second any levels are above range gives me peace of mind when I’m not at home. KNOWING that your home is safe with a product like this is amazing. There is no wondering and it takes the guessing out of the equation completely. Don’t trust your nose or be too proud to have a device like this in your home. There are so many things detrimental to your health that this device can monitor and notify you the second your home air quality becomes unhealthy so you can act immediately. You won’t regret this purchase. 100% recommend. You can’t put a price on your home or the health and safety of yourself and your loved ones in it.

This was super easy to set up! Instructions are very clear and connecting to the app ans setting up an account was a breeze.The device itself is simple but navigation is not super intuitive, it may be frustrating for someone not using the app but it does seem to work fine without connecting. I wish there was more detail available about the different air quality indicators within the app to make it a "one stop shop" but overall I love it!
