## Description

From the manufacturer

Review: Excellent Air Purifier – Quiet, Powerful, and Reliable - I’ve been using the Philips Air Purifier 3200 Series for a few weeks now and I am very impressed. The air in my home feels noticeably fresher and cleaner. It runs quietly even on higher settings and the design looks modern and elegant. The HEPA NanoProtect filter works really well, especially for dust and allergies. I also like how easy it is to use and how clearly it shows the air quality level. It’s a great product from Philips and definitely worth the price.
Review: Superb piece of kit - I bought this originally to put next to some 3D printers to control the smell and emissions, which it did well. It however soon got moved to downstairs and happily cleans our daily air. Quiet enough, the app works well and tells me all I need to know. Cleaning the filters is easy enough. This was a pricey bit of kit compared to the other available air purifiers out there right now, however I went with a brand I know and have no regrets at all in this purchase. Would happily recommend to family and friends and I have.

### ⭐⭐⭐⭐ Integration with Air+ app and Siri
*by 0***0 on 21 January 2026*

Overall, it is a good device and does the job well, but if you need to use it with the Philips Air+ app, be ready for connection problems. Once the device was disconnected from the app for some reason I was not able to reconnect again! Also, integration with Siri is partial, when you do a shortcut you can only use it on the phone not on a HomePod, as other brands
