“This German testing and comparison site gives the Philips AC0820/10 a 'good' rating of 1.6. The review highlights its mechanical fine dust filter that removes particles down to 3 nanometers, including dander, dust, pollen, and many bacteria and viruses. It features an automatic function that adjusts activity based on air quality, indicated by a color sensor. It is considered suitable for bedrooms in its lower power settings due to its low noise level (35 dB).”

“The reviewer tested the air purifier for three months and found it to be very quiet in the long term, which was the main reason for switching to this model for bedroom use.

“Customer reviews on Galaxus are mixed. One positive review states it significantly helped with severe pollen allergies and is very quiet in the bedroom. However, another user gives a negative review, calling it 'cheap goods' and stating they would not buy it again due to issues with the fan and cheap workmanship. A third review compares it unfavorably to a Xiaomi model in the same price range, citing a lack of smart features, a cheap feel, and being too loud for the bedroom.”
