Philips 800i Series Compact Air Purifier, 49m2, HEPA & Activer Carbon Filter, Removes Up To 99,5% Of The Particles & Aerosols From The Air*(1), Connected with Air+ App, Black (AC0850/31)

Recently moved to a house where I have my own home office. The little office is great, but quite small. As I like to smoke a few roll ups at night (tobacco only) it's important to keep the air as clear as possible so the smell and smoke doesn't leak to the rest of the house. This is a job that this air purifier is very good at. I can also enter the room in the morning and it doesn't smell of the night before, despite the small window. The app is excellent to use, super simple - although it doesn't seem to allow you to set a stopping time, which would be handy. However, a) The purifier needs to be set to Turbo *both* during *and* for ~ 15-20 minutes after the last puff and b) I do not believe it would deal with industrial cigarettes (ready made in a pack) as well as it does with the roll ups. This is based on another person smoking one of those in the home office; the sensor shot up to double the pollution values it does with the roll ups. If you are a smoker that puffs all day, and especially the industrial cigarettes, I doubt this purifier would make much of a dent. You'd probably need a more specialised one that's at least double the size.

Its bit noisy at auto mode but sleep mode is nice. Working on air quality improvement and easy to use. elegant design and good size.

Brilliant product and works as excepted.

This air purifier works really well-does exactly what it promises. My room feels fresher and cleaner since using it. Build quality is solid and it's quiet too. My only hesitation is the price; feels a bit expensive for what it is. If it was slightly cheaper, it'd be an easy 5-star. Still, no complaints on performance.

I have used this for a year now and it does wonders. The filter has lasted the whole year and only now it send me a notification on the app to tell me it’s time to change it. It’s used in the kitchen and living room so a lot of air purification definitely needed. Does wonders and definitely recommend for the long run.

It is a great product, when it is on you can feel the change of the air quality, auto mode is silent, so clearing the air without making any noise, turbo mode is a bit noisy, but you can also feel the air moving around - as if you would have fan on. Recommend.

Noise level was as expected as you won't get an air purifier that's totally silent, but if you do buy one that promotes itself as silent, then don't expect it to work that efficiently as it's not going to be that powerful to draw in the air around it.

After previously owning an air purifer for half the price from an unknown brand, I was relatively happy with its performance and dust was noticably reduced in the room/house.. come the time to replace the filter, it costs almost as much as the machine in the first place. So i decided to splash out on this Phillips unit, with affordable filters that I believe will be obtainable long-term... and I can honestly say, the performance is even better the air flow is stronger and the dust in the room has been reduced even further than previous. App also works very well, has all the information you could need. Yeah its not cheap, but given the brand its safe to say in the longer term it'll save me money just using filters, not to mention it looks/feels like a solid bit of kit.

After using it for some time, I realized that I used to get headaches due to poor air quality but not anymore. I highly recommend it. The turbo mode is a little noisy, but all the other features are very good.
