Delhi air pollution continues: Xiaomi Mi Air Purifier 2 and more, the top options to consider. ( Image Source: PTI)
Delhi’s air remains polluted nearly 4 days after Diwali with PM2.5 levels crossing 900 per cubic metre, while PM 10 levels were also in the near 900 mark in various parts of the city. In most cities such pollution levels would be enough to call for a complete shut down, but of course in Delhi life goes on. The only solution appears to be investing in an air purifier, which of course is temporary relief.
In our own case, we’ve seen two air eurifiers (a Xiaomi Mi Air Purifier 2 and a Phillips AC4025 40 Watt Air Purifier) struggling to cope with Delhi’s smog inside a bedroom. At best, the PM2.5 level falls to 250 after the peak of 600. For now it doesn’t look like the smog is going away anytime soon, and getting an Air Purifier, at least for your bedroom seems like the best option. Here’s a look at air purifiers you can consider, based on the ones we’ve reviewed.
Xiaomi Mi Air Purifier 2
The Mi Air Purifier 2 is one of the cheapest you can get at Rs 9,999 which can also be synced with the Mi Home app to monitor the PM2.5 particle levels in your home. The only problem with the Mi Air Purifier 2: It is currently out of stock in India. The Mi Air Purifier promises a 310 cubic metre per hour of Clean air delivery rate (CADR) and can be synced with the WiFi in your house.
In our own case, we found the Mi Air Purifier 2 quite effective when it came to bringing down PM2.5 particle levels, although in this kind of pollution the best reading you can expect is 250, which is still way beyond the permissible limit. For those who want to know, the safe limit for PM2.5 according to WHO is 25 per cubic metre.
Xiaomi Mi Air Purifier 2 is a budget option but out of stock in India.
Mi Air Purifier 2’s advantage is that this is pretty compact (240 x 240 x 520 mm) and is not too loud in auto mode. Read our full review of the Xiaomi Mi Air Purifier 2 here.
Kent Aura Air Purifier
This is another air purifier we’ve reviewed in the past, and it comes with a HEPA filter and claims to get rid of all PM 2.5 particles. It also has an built-in ioniser to remove particles from the air, along with allergens and dust.
Kent Aura Air Purifier is priced at Rs 16,000.
The Kent Aura Air Purifier has an effective room area of up-to 270 square feet and a CADR of 180 m3/h It has a child lock feature as well as night mode as well. During the course of our review, the Kent Aura Air Purifier took around half an hour to bring down PM2.5 level down from 400 to 200, but again this was not in smog season. Also like with most air purifiers it will take time to clear up the air depending on how bad the air quality is in your room. This one is still in mid-range price at Rs 16,000.

Philips 3000 Series
This is a more expensive air purifier and it shows the PM 2.5 levels on the device itself. The price for this Philips 3000 Series Air Purifier is Rs 32,995 and it has a PM 2.5 particle sensor in it. The effective area for the air purifier is 333-818 square feet and it has a CADR range of 367 m³/h.
Philips 3000 Series Air Purifier starts at Rs 32,000 and comes with an indicator for PM2.5 levels.
During the review period, the PM 2.5 levels were mostly between 100-150, and the filter brought them down to under 30 in less than half an hour. It is not as noisy either, and has a low fan mode as well. Read our full review of the Philips 3000 Series Air Purifier review here.
Priced at Rs 39,990, the BlueAir Sense+ has a CADR of 120/140/150 for Smoke/Dust/Pollen respectively. Again this is one of the quieter air purifiers you’ll buy, and it comes with its own app and WiFi support. This air purifier can be controlled via the app, no matter where you are thanks to the WiFi capability, just like with the Mi Air Purifier 2.
It has a Night mode and Child Lock, along with easy filter cleaning and replacement. However it does not show the PM10 or PM2.5 level in the room, which is disappointing at this price range. Read our full review here.
