It was installed in a 25m² space with 2 smokers, it does a very good job with smoke and dust. It is quiet on the first setting, a little noisy on the third setting but it doesn't bother. The advantages are more, I will definitely buy a second one for another area of the house

Very good purchase for a small space. I have it in my living room, which is about 40 square meters, and it works great. The first of the four levels is really quiet and very refreshing for air maintenance. If someone smokes in such a space, it is good to go to the third or fourth level, but with the trade-off of noise. It is good to clean the filter with a vacuum cleaner every week to collect the dust. The filters obviously do not last more than 5 months in any case, and I found cheap replacements on AliExpress (€13/each), because here you can find them for around €35. The mobile application is very user-friendly, if you don't want to get up from the couch or activate it remotely before you go home. I will buy it for the office as well.

In the first three days of use with the filter in excellent condition, it started emitting strong odors and doing exactly the opposite of filtering the space. Since I am highly allergic, I immediately notice it because I start coughing.

I searched quite a bit before buying it, somewhere I saw a video with the speed at which it absorbs cigarette smoke and I was impressed, since the day I received it I haven't stopped using it, the machine is incredible, it does exactly what it promises, the cigarette smoke disappears and it doesn't even leave the scent of cooking in the air.

I have been using it for about 4 months, it is quite effective. It removes odors and smoke quite quickly and keeps the atmosphere clean. The filter needs to be cleaned externally with a vacuum cleaner or simply shaken and wiped with a cloth because it collects dust. It also requires attention not to be left or used in a space with excessive humidity (over 80%) as the filter quickly develops a moldy smell.

Owner of the 400s, 300s, and 200s! The best of the best! The only one with an application with multiple functions and for programming not only the time but also the fastest fans, something that helps with filter economy!

After searching through many reviews from America and Europe, I ended up with the Levoit 200s. 100% satisfied from the first hours of use.
