A decent product, but there have been no replacement filters available on the market for over 6 months, and I assume that this will not change, which means that when it comes time to replace the filter included in the package, the device becomes permanently unusable, regardless of how good it is or not.

Smoker, I also have the corresponding Xiaomi device, the Tesla, even with a new filter, is significantly inferior in smoke detection in automatic mode, this particular one rarely detects at 3 meters. I have had it for 2 years and there is no filter available on the market, I contacted Tesla and received no response, so the device became an exhibit as with a saturated filter there is no airflow.

after 3 years I have to say that it does not clean the space in a bedroom and the odors remain as if it wasn't there. not satisfied at all.

On its own, it is not enough for a smoking room; I did not get it for dust, etc., but for smoke. You also need to have a window or balcony door open for air to come in from outside, but in winter this means cold will come in too, so there is zero benefit.
The solution is to smoke outside on the balcony, and if you go in and out, set it to Auto; it will detect any smoke that comes in and immediately switch to the third level to absorb it.

Very good product! It has been incredibly convenient for me. It easily covers a room (office) of smokers. It does take some time to clean the air, but if you give it time to work, it's as if no one has smoked at all. There is no noise. I have been using it daily for a month, about 6 hours or maybe more, and it has consumed only 3% of the filter. I bought a spare filter just in case, even though I read in previous reviews that they couldn't find a replacement (misinformation). Very satisfied. Of course, the price could be lower or the filter could cost less than 19 euros.

2026 update. Although it does an excellent job with cigarette smoke in my 35 square meter space, I can't find a filter anywhere. Be careful. Check if filters are available before you buy it. I paid 100 euros and now it's useless.

ATTENTION DO NOT BUY IT - YOU WILL NOT FIND FILTERS

I am changing my review as there have been no filters available anywhere for months, so it is simply useless now and I will have to buy another one

It doesn't suck up the dust, however lint accumulates on the filter. In automode, when I use an electronic cigarette and blow the smoke directly, it immediately turns red and starts working at full power... Also, if you put it in auto mode, it usually goes from blue to red almost immediately, which is scary when there is absolute silence... because in blue it operates very quietly and you forget it's on, and when it suddenly turns red the turbine starts working... I've had it for a month and I still haven't gotten used to it

I have placed it in a room with a lot of mold and it shows blue (very good air quality) but after a while the space smelled somewhat different. Now what can I say, I hope it works at least. Almost silent!

Very good product, it really does the job, and you should change the filter earlier than the 6 months specified, at the 4th month or when it reaches 20% of its life, it needs to be changed.

Fantastic machine.
I have asthma and it helped me from the very first day!
It's not completely silent, but the sound is not bothersome

I bought it and used it with the bag for about 3 months, how I didn't catch fire, only God knows

Quite good and does its job very well. All day in the car, as soon as you light a cigarette, it starts working immediately. At night, it stays on sleep mode and in the morning, the living room doesn't smell at all. The downside is that you can't currently find a filter on the market. Other than that, it does what it promises, quite quickly and well.

First day.......TESLA quality...for a small room that I will have it for smoking (HEETS) it will do the job! I believe it's the best for its price!

A technological marvel!! Especially for smokers, it's simply what you need. Even when I'm cleaning, it detects the dust that's being lifted. The best thing I've ever bought! Get it now!!!!

Huge difference from the first moment. I wish I had bought another one. Completely silent in sleep mode. Especially in the bedroom, the quality of sleep has nothing to do compared to without this specific machine.

Well, in terms of smoking, there was a huge difference. We were smoking with 3 people and it was like there was never any smoke in terms of the atmosphere. I felt a freshness, something definitely very positive, even in a semi-basement. From red to blue (LED, very good atmosphere), it took 20-30 minutes in a room and you could see a big difference. I recommend it for spaces where there are smokers, as well as for spaces where proper oxygen renewal is not possible. I give it 5 stars with my eyes closed!

P.S.
You can find the filter everywhere, it costs around 14-16 euros!

I came back on 4/1/2023.
For some reason, the LED is stuck on red. I cleaned it internally, but nothing changed. The only drawback is that it doesn't function well. Also, I noticed that as the filter gets older, it cleans less, which is completely normal. I recommend changing it when the filter starts to darken because after a certain point, it doesn't do much.

Very effective. It is located in a smoking room and the smell has disappeared from the space. Nice that it has colors depending on the air quality
