A couple of years back, air pollution wasn't a concern, but Today it has become a reason for many major health issues. The governments across the world are trying out various ways to fix the global air pollution issue. The outdoor air quality also impacts the quality of the air indoors. Today we can use air purifiers to improve the air quality inside our homes. Especially during winters the pollution outdoors increases hence the demand for air purifiers increases during winters.

What is the look of Mi Air Purifier 3 does it look different?

Xiaomi has kept the overall design of the Mi Air Purifier 3 similar to it's previous models, with only a few aesthetic changes. Xiaomi's has always kept it's product design smart and minimalist. The Mi Air Purifier 3 maintains the same rectangular box design with a mesh on all four sides to suck-in air like it's previous models and a fan on top to blow out purified air. It continues to be only white in color and is made of high quality plastic. 

The few differences that you will notice in the Mi Air Purifier 3 compared to the previous model are - It has a new touch OLED display, which gets rid of all the buttons from the Mi Air Purifier 3. The LED display is circular in shape and has a single touch button that can be used to switch on and off the purifier and also to change between the multiple operation modes. There is a RGB ring around the touch button which changes color as per the PM 2.5 readings of the surrounding.

The interior part of the Mi Air Purifier 3 is also a bit different than the previous versions. Xiaomi has streamlined the insides of the Mi Air Purifier 3 to improve air suction efficiency. One can see that now there are square corners with a grille that has wider openings. Also the Mi Air Purifier 3 uses a centrifugal fan, which is more efficient in throwing clean air faster.

The easy-to-open filter cover on the back of the air purifier remains the same which is a good thing. This easy to open filter cover helps to easily replace the filter when it's over. 

One short coming with the Xiaomi Mi Air Purifier 3 is that the lenght of the power cord is too short, which is around a meter. I personally feel a longer wide would make more sense.

What is the difference in indoor air quality?

Many people think an air purifier produces oxygen while cleaning the air. So let me clear that misconception first. It doesn't produce oxygen and all it does is it filters the air in the surrounding for PM 2.5 particles and other harmful microparticles that cause respiratory illnesses. If you want fresh oxygen oin your room, Try keeping some oxygen releasing house plants like a snake plant inside your house.

When you are exposed to polluted air for a long period of time you can certainly feel the symptoms of breathing polluted air like headache, eye irritation, dizziness etc. When you use the Mi Air Purifier 3 in a closed room you will see that these symptoms don't appear. With the Mi Air Purifier 3 you can sleep comfortably at nights, as it will purify the air in the room by sucking in all the harmful particles and purifying the air.

Compared to the previous version, Xiaomi has improved the air filteration process in the Mi Air Purifier 3 by adding the new Class13 HEPA filter that is known to be super efficient at capturing finer particles present in the air. It comes with a three-layer air filteration system. First there is a primary filter that works to catch the dust, hair and other larger particles. Second layer of filteration is the true HEPA filter that gets rid of smoke, household dust, pollen, and any other particles that measure as small as 0.3 microns in size. The third layer is an activated carbon filter that removes any odour, formaldehyde and other toxic substances. The life of the filter is from 6 months to 1 year depending on your use and the pollution levels.

Another thing that Xiaomi has improved in the Mi Air Purifier 3 is the suction and outflow system. The early versions used the old Eddy Fan, while the Mi Air Purifier 3 uses a Centrifugal Fan that's more powerful in sucking air into the machine. 

The Mi Air Purifier 3 comes with a  Clean Air Delivery Rating (CADR) of 380 cubic meter per hour, which is much higher than the earlier models. ALso it's puriifying capacity is more which is up to 484 square feet.

I have been using it in my living room which measures almost 250 square feet and have seen the Mi Air Purifier 3 reduce the PM 2.5 levels in the room drastically when ever I have used it. On Polluted days when the display reads PM 2.5 levels which are higher than 150 the Mi Air Purifier 3 would bring the levels down to under 50 within 15 minutes. On the least polluted days, I saw the Mi Air Purifier 3 keeping a PM 2.5 level of only 003.

There are various modes available in the The Mi Air Purifier 3. To start off with it runs in the auto mode, in which the fan speed keeps on adjusting automatically. Then there are three levels of fan speed mode ranging from low, medium and high. It also has a sleep mode in which it keeps the fan speed low in which the air purifier is very silent.

Do you need an engineering degree to operate Mi air purifier 3 or it is very easy to use?

The Mi Air Purifier 3 is super easy to use, despite all of the smart features it has. All you need to do is just plug it in the socket, press the touch button to start it. It by default runs in the auto mode when turned on.

As it has a Wi-Fi connectivity, you can also control it via the Mi Home app. Using the Mi Home app You can manage the device from anywhere you want. 

The Mi Air Purifier 3 can also be connected with the Amazon Alexa and Google Home Mini to control the purifier via voice commands.

The Mi Air Purifier 3 is also very energy efficient, and has a energy rating of 38W. Using The Mi Air Purifier 3 I didn't see a jump in my monthly electricity bill. So, if you wish to keep this switched on all the time, you can do so without thinking about huge electricity bills.


Today, Air purifiers have become a necessity for keeping ourselves healthy and The Mi Air Purifier 3 is one of the best Air Purifiers available in India. It comes at a budget price of Rs 10,000, while other popular brand products are priced at almost twice the price. With the new 3 layer filtration system of The Mi Air Purifier 3 and the new Centrifugal Fan helps the air purifier to reduce the PM 2.5 levels in the room within a few minutes.
