The company must be small because there are errors in the instructions, which are in English, confusing the input with the output. And there is a mistake in the packaging, there was a sticker that leaves glue under the protective screen sticker.
Replacement filters are available at the store where I bought it on sale for 34 euros.
The air intake is from the bottom and comes out from above through two side positions.
It has a choice of 2 fan speeds, few ions or more ions, whether the disinfection lamp above the filter and fan is operating or not, and a timer that defaults to 8 hours and goes up to 12 or goes down to 1.
It is supposed that with the filter and the lamp, the air that comes out does not have bacteria and viruses>30nm, and the electrons drop the dust down, anything that is positively charged.
I should mention here that the basic spike used by the first variations of the coronavirus was considered positively charged, so the electrons along with the lamp are a good defense for neutralizing the viruses, I believe. The instructions do not say anything about the lamp, but another UV lamp I have for disinfection states that the lamp produces ozone, which is harmful to inhale, so the lamp should be used in spaces where you are not present and then ventilated. In other words, it is good not to use the disinfection lamp for a long time and to turn it off.
The noise it makes at level 1 does not bother me, at level 2 it is not something you want to have at night when you sleep.
The low wattage and the option of low speed on the fan count as positives for me.
I did not get it for smoke, I do not smoke, I do not judge the device for that.
