Excellent Air Purifier with Ionizer! It has 5 operating levels (1-2-3-turbo_sleep). The noise on the first 2 levels is minimal, on the 3rd level it is at normal levels, nothing special though. In turbo mode, it makes a lot of noise, while in sleep mode, the noise is nonexistent, as if it is off. Of course, it also has an auto mode and in combination with the light sensor it has, when you have it in auto mode and there are low levels of lighting, after a minute it automatically goes into sleep mode (CAUTION only in auto mode). The motion sensor only opens or closes when you slowly pass your hand over the on/off button (personally indifferent). It has a 24-hour timer and a remote control. The filter is very good, it captures odors and everything in the atmosphere and more. It has a filter change indicator (every 2000 operating hours) according to the manufacturer, but in reality, when the indicator for filter change lights up, the operating hours of the purifier will be fictitious 2000 since it tends to round up (e.g. if you use it for 40 minutes, it will count as 1 hour of operation). Minimum power consumption (55 watts) in turbo mode. Overall, it is worth its money and more! VFM (295€)

Very good build quality, a truly effective filter. Difference noticed from the first minute. Large capacity.

It has very sensitive sensors. In automatic mode, it immediately detects odors such as cigarettes, etc. Another great feature is that it has both odor and particle sensors, unlike others that only have odor sensors. Its size is large but not huge. It is aesthetically pleasing. Completely silent on the first level, minimal noise on the second level, and tolerable on the third level. In turbo mode, it is quite audible, but you only use it if needed for a short period of time. The filter seems good and sturdy. If there is one negative aspect, it is that it needs to be changed every 2000 hours, while other cleaners require replacement every year. Overall, it seems reliable and worth the money.
