Philips Air Purifier 600 Series, Ultra Quiet and Energy-Efficient for Allergy Sufferers, HEPA Filter Removes 99.97 Percent of Pollutants, for Rooms up to 44 m2, App-Controlled, White (AC0650/10)

Smart looking air purifier that was easy to set up and easily connected to the app. Pleased with the purchase and that the 'quiet' mode is great at night and doesn't keep us awake. Putting it up to medium throughout the day means the room does actually feel 'clearer' at night.

I bought this as my first air purifier back in January and I wouldn’t be without it now. I run it 24/7 in my bedroom and it’s definitely made a difference to the air quality. I feel like I sleep better with it on too.

Working well so far, I will update after peak grass hay-fever season.

This is really effective, does the job perfectly.

Brilliant, Removes the dust from my living room, the air is cleaner, makes such a difference especially as I have a parrot and having a house renovation on the go, I will buy another for my bedroom.

This was bought in the hope that air would be clean enough so it did not trigger asthma. The improvement made by this device in one day alone was worth the punt. Patient has heart failure and severe asthma and is in the room for long periods and as such there is normally a large amount of dust etc. the sun streams in the early evening and the dust can be seen floating around like a star strewn sky. With the device running there was a marked decrease so possibly you could say there were thousands before and a handful now. Very impressive.

Good and silent if you run it on lowest speed. Only negative aspect of is that it doesn't have carbon filter. That is why it is not effective against smoke and bad smells. I don't know why Philips didn't put carbon filter in it.

Only buy if you feel lucky or do not mind fan bearing noise, Out of 3 units I have purchased from various sources, only 1 unit is whisper quiet at lowest setting, so much so that you barely can hear the airflow with your ear next to the unit, no other noises. The other 2 units I have bought and sent back after just a few hours (including 1 from Amazon), because there is a drone / humming fan bearing noise which is a good 10dB louder than the airflow noise (I did measure about 28dBA - 30dBA on both units, Philips spec states just 19dBA). The noise is not only audible, but also far less pleasant than the wind/airflow noise. In summary, only buy if you intend to use unit at medium / high setting or do not care about the low noise feature at minimum airflow setting. Shame really, as I liked the simplicity and low power consumption of this design.
