Philips Air Purifier 600 Series, Energy Efficient with Smart Sensor, For allergy sufferers, HEPA filter removes 99.97% of pollutants, Covers up to 44m2, App control, White (AC0651/10)

The air purifier itself is great and does exactly what it’s supposed to, however, the app was a nightmare to get working continuously, although looks sorted for now at least and is nice and helpful to see air quality in local area as well as the room and the percentage guidance for filter cleaning and life obviously very handy. Easy to set up just remove bottom and then cover from filter replace filter and bottom of device, just use app to leave speed on auto and adjusts quickly to changes in air quality, longevity of filter will depend on your own atmospheric conditions but also deals with smells very quickly as noticed when cooking.

Very efficient unit, exceptionally quiet and excellent filtration. This unit also offers network compatibility with the Phillips ecosystem, so you can monitor and control the unit remotely with your phone. At this price, presently £60 on Amazon, it’s a no brainer.

I purchased this air purifier for the bedroom, as this room does sometimes suffer from mould especially during winter months when I do not open the window. I know that these air purifiers are not really meant to be used as a tool for mould control but it does appear to be helping to keep it at bay. The build quality is very good, it was easy to install just downloaded the app and it connected without any problems, the app is informative and functional, keeping you up to date with air quality readings, however it does sometimes disconnect from the app for no apparent reason. I keep it on an automatic setting which means it will adjust fan speed etc automatically depending on the quality of air it senses, so I just let it do its thing. I have had no issues with noise levels, although obviously there is some fan noise when it goes into turbo mode but wouldnt say it is excessive and it never stays in that mode for long. It has never woken me up of prevented me from sleeping. One important point to note is that when you first use this unit, please take out the filter and remove the sealed plastic bag that the filter is in. I neglected to do this, so for a good month it was trying to draw air through the sealed filter and I am lucky it didnt burn itself out or malfunction, however until I realised I thought the unit was defective as obviously it wasnt cleaning the air. As far as functionality it does appear to be doing a good job of prurifying the air as most of the time the reading in the app is showing that the air quality is good. Although I do not have accurate room length and width measurments, the room that it sits in is aprox. 12ft by 10ft. The only reservation I have, hense 4 stars and not 5, is the acuracy of filter change information as I suspect rather than it actually sensing that the filter needs to be cleaned it just seems to be telling me to clean the filter every couple of months, even though on inspection the filter looks perfectly clean. Incidently the filter is very easy to access, just unscrew (by hand) the port at the bottom of the unit and pull the filter out. Over all I'm very pleased with this purchase and it represents good value for money.

We got one of these as both our boys have asthma and cough loads at night time. So we have put it in their room and no more coughing at night. We leave it on auto all the time and we haven’t seen an increase in electric usage. The device is bigger than expected, but this means it collects more quickly. You can see the air quality when you are in the app, set a schedule and change the mode. It’s not loud at all, it’s more like white noise mild when on turbo. Auto you can’t even hear it is on. Very easy to empty and clean, feels well made, I’m going to buy another one for our bedroom to help with our sleep, I’m kinda hoping it’ll stop my husband from snoring lol. Would definitely recommend.

Works great on the auto mode but can be switched to other modes manually with a tap of the top. Linking it to the app was a pain at first and simply wouldn't work on the first day so I gave up and tried a few days later. It then decided to work for some reason and connect despite not doing anything different. Even if you can't get it to connect, it still works as intended without the app connection, you just won't be able to control it remotely or set a schedule if you want one. I just leave it on the auto mode anyway and it does the job, nice and quiet unless it needs to ramp up for a minute or two when it detects a lot of dust or particles in the air.

This is the first time I got an air purifier, so I don't know if it's good enough for the money, but it did make a difference in air quality and I constantly use it. The colour blends with the wall, I forget it's there, it is very light weight. You can hear it when it's working but it's not noisy enough to bother me.

Just started using it, but works like a charm, cleans air after cooking, sanding and airbrushing, perfect for both nail salons and surprisingly a good blower for charcoal in your shihsa, not to strong and not too weak 😂

Looks good and does the job well. I can feel the quality of the air in my bedroom improved. The air coming out of the machine is decidedly cold but that's not an issue for me. The auto mode is great, the machine reacts to a change in air quality quickly; and the scheduler works as well. However, I won't be keeping the machine for two reasons: 1. In the sleep mode it emits an annoying, oscillating noise that makes it impossible to relax! I was advised to put the purifier on top of something else to make it less resonant. I also removed and flipped the filter upside down. Nothing helped. The noise persisted and that's a no from me. 2. The app is not great either (it disconnects easily) and data collection is highly inaccurate: I tested the device across the whole AIA spectrum, hitting 'poor' (red zone) and over 150 μg particles TWICE, and yet non of it registered on the air quality charts. It doesn't tell you which allergens are most common around you, either. So all in all, for the price it does its job but I need something more reliable.
