There’s not much to complain about in the Philips AC3821/20 air purifier. The device features good air cleaning capabilities, comes equipped with a HEPA filter that traps harmful particles and a carbon filter that gets rid of VOCs. Additionally, there’s a humidifier feature included as well, which can come in handy during dry seasons. The device is priced at Rs 37,995 on the company’s official site and we would have not really recommended it for that price as there are similar options available at a lower price. However, we noticed that it retails for around Rs 22,999 on Amazon at the time of writing the review, which makes it an enticing proposition.
Philips Series 3000 AC3821 Air Purifer is an air Purifier which is perfect for Air Purifer. It works towards improving the air quality with the help of Air Purifer and Humidifier. The Purifier is good enough for an area measuring 860 Square feet and has a CADR (Clean Air Delivery Rate) of 310m3/hour. It features child lock,, 4 manual speed settings fan speed modes but does not support WiFi Connectivity.
The customer support service is pathetic...suggest go for another brand.specially when you are in DelhiNCR , where the usage is high.
Very much overpriced plus blue light does not let u sleep Touch system not very user friendly Must have given remote and wifi at such high price
Works like a charm.
Good one
Good product.
even humidifier it provides a suffoccating experience after 2 hours.
The purifier is working fine and the best part is the added humidifier function. It’s good specially for dry climate and the water tank lasts for the whole night. LED can be dimmed if required. Also the humidity mode can be switched off if not required. It reduces the pm 2.5 level to less thsn 10 from around 90 with the doors and windows shut. Overall a good product. Only drawback for some people could be the lack of smart app connectivity.
The air stays dirty even when i used it in a 14X14 room, closed windows and doors. The filteration is not effective although display is accurate. It is just an expensive piece of appliance that is good only to display. 1. no filtering, after 4 days continuous running, 0 effect almost 0 on a room less than half size of this filters capacity. 2. no breathable difference in air, location of property: delhi, time: stubble burning festival season, pollution levels: 300+ 3. delivered results: before filter: 220, after 24 hours running: 180-190. 4. The water tank is not high capacity and runs dry in a few hours for humidifier. I will have a custom made filter in our house, hidden inside false ceiling with 8 times the capacity of this one and install good cartridges with quad exhaustintake ports and ultrasonicheated humidifier combo. Its better to build your own if you want real filtering, these filters dont work, they are tiny compared to the air volume and misleading in their capacity.
Error Code E1 thrice on day 1.
Excellent appliance, works great brings down the pm2. 5 to 2-3 from 300+ in 15-20 minutes. Humidifier is the icing on the cake.
