Mi Air Purifier 2 Review


In the early-90’s, the water that came out of the taps in most homes and offices was fit to drink and complete all other routine work. If someone was really worried and concerned about the water quality at that time, they would attach a dumb filter worth no use to the tap to have clean drinking water. Not anymore. Things have changed and the quality of water is deteriorating day by day and it seems same is the case with the air we breathe. That’s the reason we all need an air purifier to breathe clean air.

According to WHO, India has more than half of the world’s 20 most polluted cities, considering PM 2.5 particulates present in the air. But, there are so many pollutants present in the air, which origins from a bulk of sources including vehicular and industrial smoke, burning of garbage, construction, dust, dissolved gases and odours. The fact of the matter is, the air around us is never as clean as it appears to be. In fact, the invisible contaminants are the ones that pose the greatest risk to our health.

After China, Xiaomi saw India as the next best logical place to launch its Mi Air Purifier 2. This air purifier is actually a Mi ecosystem product, which is not made by Xiaomi but by a partner company and is marketed by them. Following is the detailed Mi Air Purifier 2 Review to help you make the right decision for your home.


The Mi Air Purifier 2 is designed in such a way that it absorbs polluted air from all the four sides and releases clean air from the top. It has an auto as well as manual mode. It also comes with two noise selection modes, silent and max. But, the most important thing in an air purification device is the filter. So far, all the purifiers available in the market supports a flat filter compartment in which three to four layers are assembled. One has to manually put in each filter and take it out to clean.

Xiaomi supports a cylindrical three layer filter design. The first layer is the PET filter that catches and traps large particles like dust, hair etc. The second layer is the EPA filter, which blocks the tiny particles (including PM 2.5 particulates). The last layer is the activated carbon layer for formaldehyde and odours. The EPA filter is capable of only eliminating pollutants at an efficiency of 95%. The products from its competitors using HEPA filter cleans at an efficiency of 99%.

Here the Mi Air Purifier 2 comes up with a trick up its sleeve. Xiaomi connected your smartphone to the air purifier using an application. Using the Mi Home app, the air purifier connects to your smartphone, which allows you to check the PM 2.5 level in your room. It also let you know that when you need to change your filter, to continue inhaling clean air. This all happens through Wi-Fi and works on both Android and iPhone. You just need to download Mi Home app to use all these features.

There is a button on the back of the air purifier, you just need to hold it for a few seconds and wait for the light to blink. Open the application on your device and pair it with the purifier over Wi-Fi.

China giant Xiaomi claims that the Mi Air Purifier 2 only takes 10 minutes to circulate clean and purified air in a room of 21 m2 area. Well, it certainly manages to lower down the PM level from the hazardous levels but as per some customer’s reviews, it was not working the way it should be. In turbo mode, it can decrease the air quality index in a closed room from 80-100+ levels (harmful levels) to under 50 level (good) in less than 20 minutes.

The only thing missing is a visual indicator on the air purifier to check the air quality at a glance. It does not have any set of coloured LEDs that can tell one how good or bad the air quality in a room is. For this you need to open the app every time.

Xiaomi Mi Air Purifier 2 is available at an unbelievable price of Rs 9999. But the air purifier comes with a filter life of about six months. The Chinese giant recommends to replace it for better efficiency. The filter is a major part of the air purification device, which comes at an additional cost of Rs 2499 and this will be a recurring cost for the consumers. Many consumers reported that their air purifier stopped working merely after 20 days of use, because the filter needed to be changed. This makes the purification device easy to own, but difficult and expensive to maintain.
