Philips Air Purifier 900 Series, HEPA NanoProtect + Active Carbon, 65m²

- Useful app. Easy to use and offers good options for using the purifier remotely/timed. Settings for ambient light/readouts etc. - Good form factor for small bedrooms etc. - Very low noise. - Sensor seems effective and gives regular readouts. - Filter lifespan seems okay - 12 months. Seems will need cleaning approx. once a month. New filters are a reasonable price. So far I'm very happy with it. It has all the features and settings I would need. From past experience with purifiers, I just hope that they keep supplying the filters as it's very disappointing when a company stops offering essential service parts for a product after a few years. I hope Philips will commit to at least 5 - 10 years for the current models but we will see. Bought a replacement early just in case. I also bought the 2200 model shortly after. Overall, if the size isn't necessary, I actually think the 900 model is better in several ways considering the price. Slightly quieter and seemingly more accurate sensor. However the 2200 does have a 3-year filter life, which if it lives up to will be a significant advantage.

Absolutely one of the best things I've purchased. I suffer with allergies badly, the smallest amount of Dust and pollen really ruins my day and when it came to sleeping I was just in a mess. This air purifier has changed everything, I left it on turbo in my bedroom for a good 2 hours while I went out, came back and for once in my life I could breathe in my room. The App is great allowing you to control the device remotely and set timers and automation etc. It also tracks air quality and gives you really important data about the quality in the room and local pollen levels etc which is great. I mainly leave the device on all day on automatic mode which is great as its near silent and kicks in only when it detects bad air quality making the power consumption very economic. It also gives you peace of mind your room is constantly being cleansed and re populated with clean air. The device to my knowledge requires 23 Watts of power at its maximum performance, this is next to nothing. A kettle uses 1500 watts (on average). You could run over 65 of these air purifiers for an hour and it would cost you less than boiling the kettle once. That to me is insanely good. Especially if you're in the UK and having to deal with our current energy prices. Overall, this is a must buy if you suffer with allergies, are exposed to black mold, have Dust in your home etc. It also cools your room so I can already imagine how blissful this will be in summer! 10/10 purchase

A good machine, that does what says it will do. Quite on night mode gives a an indication of air quality. Noisier at higher levels. Time will tell if it will reduce the hay-fever of my grandchild. At the moment his coughing has reduced dramatically and he has not needed his pumps. Very good for the price (paid £100) and I would recommend

Excellent air purifier, works well and good filter life, works on the App with WiFi and has manual controls, has air quality info on the app which is useful

+Quiet +App easy to use +Auto Function +Can get replacement filters +Feels well made +Clear display -On auto it almost never speeds up, has a high tolerance for air quality before speeding up. Other brands (Shark) much faster to respond. Overall a good air purifier which reacts to major air changes but generally runs nearly silently in the background.

Amazing machine. Great value for money. Easy to connect to your phone and use remotely. Very quiet unless in turbo mode. Removes smells and dust etc. App is easy to use on your phone even when at work.

It took about an hour or so to set up because I had to mess around with my WiFi settings to get a 2.5 connection, but while I was doing that it was busy cleaning the air in the room and by the time I was finished it said the air was "good" so it seems to be working pretty well and the app is decent too. My cat is enjoying sitting next to it and I can definitely feel a difference already like I can breathe a lot better. I particularly picked this machine because of the size and colour, I'm quite happy with it. The sleep mode is nice and quiet, by the time I woke up it had put the air to "good" If you have issues connecting this to the internet or the app, you probably need to go into your WiFi settings for your router then split the 2.5 and 5 internet channels in the advanced wireless settings by giving them different names. Then you connect this device to the 2.5 WiFi signal, then you can switch back to 5 on your phone and the device will remain connected.

Works well with a good app but has a loud humming noise even in sleep mode which prevents me sleeping

Loud on the lowest setting

Viene con enchufe inglés. He tenido que comprar un adaptador para España. Por lo demás es el 2° que compro porque va muy bien. El 1º venía con enchufe de España.

La prise n’est pas européenne !!!!!

Usato la prima volta per quasi tutto il giorno in più la notte. Però mio figlio la mattina appena sveglio ha avuto lostesso un po di asma! Non so se restituirlo visto che non ha funzionato molto

Me ha llegado con enchufe para Reino Unido. En ningún momento se avisó que el aparato viniese de allí. No puedo ni enchufarlo para probarlo. ¿Cómo puedo conseguir el enchufe adecuado para el país en el que lo compré?
