So far so good 👍🏼 No problems at all. Clears air perfectly.

Here is a try at a review of this product after using it for an year now.Use Case :-I am a NCR resident and the air pollution is as we know one of the worst possible if not the worst. I have it installed in the bedroom, about 300 sq ft so well within the advertised max room space. While using the purifier the room is kept closed to minimize pollution addition.Build Quality :-The purifier is sturdy in its built and aesthetically pleasing. It has a large front grill that acts as the air inlet, and an arched back that has a larger grill for filtered air outlet. The arc helps the air to be released vertically upwards and hence does not add to direct cooling for anyone sitting in front. This helps the filters use in winter which is the main season where it is required. The top of the filter has a dark panel with touch sensitive buttons and a decent sized circular LED screen. The 4 buttons are - Power, Night Mode, Fan Speed, and Child Lock.Setup :-The air purifier is shipped with its parts packed separately. Thus on unboxing the same has to be setup for use. The setup is pretty straightforward. The main filter units front can be released and the individual filters aligned in order on the central space. The installation order of the filter is as followsFirst -> HEPA Filter. (The same has indication on top to correct installation. You can also go with keeping the Phillips Branding on the top left Corner)Second -> Active Carbon Filter. (The same has indication on top to correct installation. You can also go with keeping the Phillips Branding on the top left Corner)Third -> Pre Filter. This one actually clips in place and is used to filter out the larger dust / impurities so that it does not clog the other main filters.Thus the filtering order is Pre Filter -> Carbon Filter -> HEPA filterWorking :-The air purifier can be set to different modes. One of them being the automatic mode that automates the purifier working thanks to the inbuilt air quality sensor. The pollution level sensed regulates the fan speed accordingly. 4 levels are programmed and are indicated on the small circular LED screen by means of circular rings of different colors - Blue (Min), Violet, Pink, Red (Max). Red level would put the fan in maximum speed and blue would turn off the filter automatically.If you are not a fan of the automatic mode, you can use the fan speed button to move through the option of different fan speed/modes. They areFan Speed 1 - Indicated by 1 on the screenFan Speed 2 - Indicated by 2 on the screenFan Speed 3 - Indicated by 3 on the ScreenAutomatic Mode - Indicated by A on the ScreenAllergen Mode - This can be only added on top of Automatic Mode. It essentially bumps up the speed a bit on all the different color levels. This is to suit the sensitive people as this improves the air filtration rate.Turbo Mode - Indicated by T on the Screen. This puts the fan in the maximum speed possibleThats pretty much the major functioning of the air purifier. Additionally the filter has an automatic/forced night mode. The purifier automatically detects the lighting in the room and once it senses low to no light it automatically goes into night mode. The same can be forced by pressing the night mode button the purifier. What this does is that if the filter is in automatic mode, the fan speed is reduced on all the levels so as to minimize the noise.Summary :-So as to summarize my review and add my view here, the filter works pretty well for the use case i have. On regular winter pollution days its able to keep the air quality in control, even when working in automatic mode its able to go down from Red levels to Blue. Switching on an off intermittently as per the air quality levels. On drastic pollution days it has a tough time managing the air quality in automatic mode and i have to force it in turbo mode to get the air quality in control. If not too much of an air change is happening in the room throughout the filter is able to get the air quality to a much acceptable levels.The air quality indicator is a great value add on to the product. Much that is missing in similar priced competitors.I am little disappointed in the night mode working as it compensates air quality over noise. I believe the purifiers task is to ensure that the air quality in room is as good as possible. By reducing the fan speed to reduce noise works ok on normal pollution days, but is totally useless in any thing even a little worse (when i dont want to use turbo mode just yet)Durability of the filters has been decent. I have used it all through the winters last year and intermittently the summer this year but am yet to get an indication to change the HEPA or the Carbon Filter. On yes that reminds me the Air purifier would automatically sense and indicate when a filter needs to be replaced by displaying an error code on the screen. It even does that for the pre-filter which does not have to be replaced but just cleaned/washed. That i have received 3-4 times this past year.Overall i still strongly recommend this product- Good performance with a decent price which has been slashed a good amount from when it launched.

We are staying in Navi Mumbai so many construction works are going on around us.We have purchased this only for our new born baby due to some air pollution issues.. It's works beyond my expectations. Highly rated product and pocket friendly also. It's almost quiet in operation and fan speed also good. The air quality actually changed after installation of the product. So I recommend this to everyone who is searching for a air purifier.

When it comes to home air purifiers, the Phillips A1215 stands out as a true game-changer. This remarkable appliance has exceeded all my expectations, leaving me absolutely thrilled with its performance and features. Before I start, I would like to say that the best feature for me was the auto on after power cuts and it even remembers the last mode it was in.From the moment I installed the Phillips A1215 in my home, I noticed a significant improvement in the air quality. It efficiently captures and eliminates airborne particles, dust, allergens, and even pet dander, ensuring that the air I breathe is fresh and clean. The difference in air quality is truly noticeable, especially for someone like me who suffers from seasonal allergies.One of the standout features of the Phillips A1215 is its sleek and modern design. It seamlessly blends into any room and doesn't disrupt the overall aesthetics of my home. The intuitive touch controls make operating the air purifier a breeze, and the display is clear and informative, providing real-time feedback on the air quality and filter status.The A1215's performance is backed by advanced filtration technology. Its VitaShield IPS technology, combined with the extra-thick NanoProtect HEPA and AC filter, ensures the removal of even the tiniest pollutants from the air.

Even when running on higher fan speeds, the noise level remains unobtrusive, which is a significant advantage compared to other air purifiers I've used in the past.Another aspect worth mentioning is the A1215's energy efficiency. It's great to know that I can leave the air purifier running throughout the day without worrying about excessive power consumption. The energy-saving features not only benefit my wallet but also contribute to a more sustainable lifestyle. Only consumes 10 watts in Auto mode and 50 watts at max speed. Used smart plug to measure.Maintenance is a breeze with this air purifier. The smart filter life indicator notifies me when it's time to replace the filters, which is incredibly convenient.

I received this product, qorks well and all but whenni check the gas. Its already at Low! New product without gas or used product sold as new?!I would not recommend buying this product.

i take same model 1711, 1 from amazon and second same model from phillips showroomCons:AI mode will not work as you want, if your room size even 10x10 (100 sqft)Prosvery silentif set fan on 2, its quit and clean air properly .here in my area show aqi 150+ when start, and after 2 to 3 hours its show below 10, first 10 min it will reduce as much as approx below 40

I am using this air purifier for last two weeks and happy to report that it has significantly improved the air quality in the room. It’s very silent during the night mode and the light also turns off automatically to provide good sleeping conditions. Aqi meter on the display is missing but the colour code led compensates for it. Overall a good product. Got it for Rs8100/- during the sale.

Good
