This purifier is compact enough (perfect for a room), low noise, and after a few minutes the air is clearly cleaner. The effect is gradual, we feel that the air is pure, it's very nice. My husband suffers from hay fever, and his nose is less irritated with this purifier. Small problem: the sensor that indicates when to change filters pushes for consumption. After two weeks, with a use of 1 hour per day, there is already a light and a beep that indicates a need to change filters. And yet, when you open the device, you can see that it is perfectly clean (thankfully, after barely a dozen hours of use!). You can reset the detector, but it is a pity that the information it gives is not correct. For information, the necessary filter Hepa AC4124 and AC4123 Hepa cost about 30 euros each, so a total cost of 60 euros each filter change. It is an additional cost to be taken into account. In conclusion, a very nice and purifier that works, but the price of entrerien (filters) is not negligible!
