My revision 14 Aranet4 now has the instantaneous measurement button after recent firmware update

Thanks for review! Ended up ordering INKBIRD IAM-T1. Regarding rechargeable batteries, since many years I use rechargeable AA or AAA batteries from amazon, so it's not really a factor.

exactly what I was looking for, thank you so much!

thanks for the great info :D

Have you used a CO2 sensor for outdoor?

What portable CO2 you can recommend that can synchronize data in the phone?

Have they stopped making these? I can't find them😊

Thank you, Ethan!

Thanks for the video, and the focus on air safety. If you are interested, would you like to compare test our 4-in-1 portable detectors (CO, CO2, temperature, humidity)? :)

I bought my ARANET4 on July 17, 2022, and I just checked the battery life. It has roughly 30% battery life remaining on the stock, included AA batteries. Absolutely incredible battery life and features!

You didn't really say how accurate the different devices are. At the very least put a bunch of them together in different environments and see which ones match.

You mention data, but not which ones support getting the data from using your own program. The manufacturer's app or software is useless, and uploading data to the cloud is unacceptable. Just have it present a minimal webserver serving a json with the data. But which one's support something like that?

thank you!

Thank you so much, this helps alot!

Have you had the chance to test the super small Airvalent monitor? Price is close to Aranet, but looks a lot more mobile...

what virus

In a mostly closed purse or bag, or a jacket pocket, is an Aranet able to measure the carbon dioxide? Or does it need to be taken out completely? It is very expensive, so I am afraid it would be lost or stolen if I leave my bag zipper open all the time.

We recently ordered an Aranet4 from Amazon (when it was on sale). It was quite worthless and we had to return it. We did notice in the one star reviews on Amazon that the former version was excellent, but the newer version sucks. We did side by side with out little Vitalight. Perhaps our Aranet was defective, but I suspect the reviews were accurate that the quality declined in the later model. Thanks for your reviews!

IMO it’s important to be exposed to viruses but these are cool for places you control the opening of the window because co2 can decrease brain function also why is your house at 3600

Great Video, thanks :) However none of these can identify a virus''' after all not even the scientists could isolate them :) Check out Dr Sam Bailey it you want to know what Imean :)

Thanks for the review! Will use your affiliate links. I wonder what are your thoughts on airthings view plus (seems quite pricey) and Qingping Air Quality Monitor (not sure how accurate are readings).

The most soy thing I’ve seen

Re: internal rechargeable battery vs AA batteries: lithiums are more compact usually, and the battery case itself won't take up any space, that's a plus. But if it can run on rechargeable AAs, that's a win in long term too: you won't have an internal battery that maybe hard to replace, or can't be replaced without damaging the enclosure. Of course it doesn't run on rechargeable AAs, because of the lower voltage, that would be a shame...

A good CO2 monitor should be a staple in every household, similar to a fever thermometer. I purchased my first CO2 measuring device several years ago when they were still relatively unaffordable. Meanwhile, I also own a device from Withings, which unfortunately cannot be calibrated and, on top of that, has a much too long measurement interval. My preferred device remains the "TFA Dostmann AIRCO2NTROL 5000" because it features LEDs that allow for a quick assessment of the current status. The threshold values are also programmable, and the brightness of the LEDs doesn't disturb in the bedroom. The device is powered via USB and can be found at least in the German Amazon store. By the way, if your devices are displaying correctly, it's time to open a window 😉

Since I made this video, I've had a chance to review the SmartAir CO2 Monitor. This is an inexpensive monitor (around $70), that offers almost all of the features of far more expensive monitors such as the Aranet4 Home and INKBIRD IAM-T1. It's also worth considering if you want a CO2 monitor! breathesafeair.com/smartair-co2-monitor-review/

How do you know the Qingping monitors are NDIR? It doesn't say that anywhere on their website/amazon.

Have you tested the Airthings monitor?

I don't care about the app. All I want is a device that tell me the concentration of carbon dioxide so that I know when I need to open the window to ventilate. As I live in a cold country (Canada), I cannot leave my window open all the time. Aranet 4 is certainly a great device but I feel I would be paying for options that I don't need.

INKBIRD's T1 is a sensor from Sweden, I have this, it's very nice!

Hi, good research. Have you ever tried any Tuya device? I am using one with the Tuya app compatible it’s a cheap one (~30USD) not sure if the sensor good or not.

Thank you very much! Super useful video.

Thank you

Thanks for the video. I would be interested in a comparison of the Inkbird Portable Monitor which is a similar price point

discount code is not working (USA).

Thanks. You mention there would be a link to the case from Amazon for the Aranet4. Can't find that. Can you provide some more information?

One error: When initially turned on, the device will perform an auto-calibration within 24 hours as per the manufacturer’s specifications. After the initial 24-hour period, the device will auto-calibrate itself every seven days. In the video, I mentioned it will auto-calibrate every 24 hours. This is not true. Rather, it will auto-calibrate within the first 24 hours, and every seven days afterwards.

Really grateful for my Vitalite CO2 monitor. I feel like “where has this technology been all my life?” Thinking of all the headaches that might’ve been due to high CO2, so many I bet I could’ve prevented

Finally a review of my Co2 monitor!

U don’t need masks anymore
