I have extensively tested the previous model and it was a bit of a mixed result with the strongest selling point the price being really affordable. You can see my review and test result on our blog [1].
One of the biggest negative points that I found was that the traffic light cut off points are way off. So it shows a green light from 0-35 μg/m³ whereas the WHO defines the annual limit now at less than 5 μg/m³.
Unfortunately in this new model this seems still to be the case and has not been improved (according to the manual [2]). So the VINDSTYRKA still gives misleading indications through the traffic light but at least you can now see the μg/m³ on the display and make a more informed judgement (compared to the old model without display).
It is difficult to make a judgement on the accuracy without really running it through a test cycle but it is definitely missing a CO2 sensor. Measuring CO2 indoors is most likely the most important parameter, especially if you live outside strongly polluted areas e.g. in Asia.
CO2 sensors that give good accuracy are relatively expensive and I believe it was probably shelved because of costs which is a pity. So this looks like a big missed opportunity but I will try and source one of these and write a review.
If you are interested for a DIY kit with high quality sensors, check out our AirGradient kits [3].

- berberous 4y agoHave you tested Awair? How does Airgradiant compare?
- ahaucnx 4y agoAwair uses much better sensors than the Ikea and the accuracy should be quite similar to the AirGradient.
- mcjiggerlog 4y agoAgreed - the lack of CO2 monitoring is a shame. I bought a relatively inexpensive CO2 monitor (~90 EUR) and it was really an eye opener. If you work in a small home office, the speed that you reach levels of CO2 that will have a noticeable impact on your mental faculties (eg 2000ppm) is incredible. Definitely makes you step up your ventilation game!

- noja 4y agoIkea: Does the new model still have a fan that annoyingly switches on and off every 10 seconds? AirGradient: support for Homekit please!
- kixiQu 4y agoWhile it won't catch "you need to open your office window", I'd recommend it to anyone for their kitchen. VOCs and PM2.5 can get real bad without the cook realizing so anything that's even slightly reliable can be useful
- Animats 4y ago> Definitely missing a CO2 sensor. CO2 sensing devices have become cheaper. No need to buy a kit. Here are two from China.

- jahnu 4y agoHow’s the accuracy?
- criddell 4y agoYour AirGradient ONE page says "contact us for pricing". How much is it? Why don't you list the price?
- ahaucnx 4y agoUnlike our kits, the AirGradient ONE targets commercial customers with large and sometimes complex requirements so the price varies depending on this. But to give you an estimate it is somewhere between USD 200-300.
- dgellow 4y agoDo you sell them in europe too?
- ahaucnx 4y agoYes. We ship worldwide.
- nebben64 4y agoHow does AirGradient compare with the Aranet4 CO2 monitor ?
- ahaucnx 4y agoCO2 should be very similar because we also use a Senseair CO2 sensor module like Aranet but with the AirGradient you can also measure PM and optionally TVOCs.
- cptskippy 4y agoWhile the Ikea Vindriktning might not be accurate, I have found it incredibly consistent and reliable. I bought a handful of them and hacked them with ESPs (thanks Hypfer) to push data into Home Assistant. They're sensitive enough that I can track if/when our cat boxes get cleaned. We have a 3 story house and have observed air quality changes in our bedroom and office that are immediately above our stove in the kitchen. https://i.imgur.com/Mjk65pL.png https://i.imgur.com/Mjk65pL.png There isn't a lot people can do to affect the baseline air quality in their homes, but having a sensor that can identify negative change is significantly better than nothing. A precise and accurate sensor is nice but doesn't offer much benefits above or beyond that.
- privacyking 4y agoI've been looking to get a few sensors and ended up going with awair for my first one after reading some comments in your forum. When is your updated PCB (with better ground plane, etc) going to be released?
