Just to give you an update if anyone is wondering, i ended up buying the Xiaomi 3C air purifier for about 100€ and it works the same like the purifier in the video i posted above. All the smoke gets sucked in directly like a kitchen exhaust and it releases a smoke-free air. It's exactly what i wanted and i'm happy with the results. Thanks
@Don Manzoni for the suggestion.
It has a 3 stage filter: Mesh/HEPA/Carbon, and they need to be changed every 3-6 months depending on the use. I use it only when smoking.
The filters cost around 25€, not so expensive for what they do and for how long they last.
They also have few versions of the filter: standard, anti-bacterial and anti-formaldehyde. They all work the same collecting the smoke and they cost the same, just different types of HEPA.
I think it's a good investment for anyone like me who likes to smoke inside, it doesn't use a lot of wattage either, less than 50w (i think 20-30w).
And surprisingly it's not as loud as i expected, i would say it's quieter than a regular exhaust fan for grow tents. It's still loud, but acceptable for those 5 minutes of smoking. I couldn't bear the sound all day though.
The only thing that i don't like about this Xiaomi purifier is that you need the wi-fi/bluetooth mobile app to fully control the speed of the fan.
The buttons on the device are almost useless, it either works on 100% power or 1%, no medium speed without the mobile app.
The standard mode works at full power all the time, and the automatic mode starts at 100% and gradually decreases the speed as the air is becoming cleaner, but it takes a long time. And while smoking, the fan speed never decreases because the sensor always reads as high pollution.
The night mode is pointless, it works on 1% or even 0%, doesn't make a sound and doesn't pull any air, the pollution sensor is stuck on the same number all the time. I'm not sure if my device is faulty or is it meant to purify the air over the course of a night.
I wish there were several fixed speeds to use it on low setting without the app.
And i also regret for not buying an air purifier with an ionizer. Since i'm using the device on my desk next to my ashtray, all the dust particles being sucked from the room are passing right next to my face, and i'm breathing it all in. So it's best to place it further away.
I didn't think about that, i suppose the ionizer would help making the dust heavier and less floaty, and deactivate the allergy-inducing particles.
But then again, i read somewhere that some cheap ionizers produce ozone as a byproduct so probably shouldn't cheap out on that.
Anyway, i finally found what i was looking for and wanted to share my experience in case someone finds it helpful. Cheers!
