Xiaomi Mi Air Purifier 2 Review

mi air purifier reviewXiaomi has taken the consumer world by storm over the last five years. It’s not difficult to understand why. With its line up of smartphones and household appliances which have high end specs for mid-range prices, it’s won the hearts of Indian consumers across the country.

Several years ago, Mi introduced the Air Purifier 1 to its home market in China. Chinese cities are world famous for their terrible air pollution and Xiaomi had come up with a winner with its air purifier. Last year, Mi introduced India to its Mi Air Purifier 2. Which Air Purifier finally got its hands on the device that has been selling like hotcakes and with Diwali 2017 season upon us, sales are likely to spike even further.

Form Factor

The Mi Air Purifier 2 takes on a square tower form with slightly rounded corners. The air in the room is sucked through the grates in the lower half of the appliance, passed through the air filters and blown out the top by a powerful fan.

The height of the air purifier is 52cm. It’s not the most compact of purifiers that we’ve seen either, at 24cm in width and depth, but overall it’s pretty sleek.

App Based Control

The Mi Air Purifier takes an unusual approach to controlling the appliance. On the top is a single on and off switch and down the side are three indicator lights to let you know what its status is. Instead of a control panel like every other air purifier on the market, Mi allows you to control the entire device by smartphone. You download an app to your Android or iPhone, connect to the air purifier via wifi, and control everything you need from the app.

All the data and control is available via the app. It begins to learn your habits, such as switching off the device at a certain time when you leave home or switching it back on when you get back. It tells you when the air quality in the room is deteriorating and automatically suggests a setting to keep the air clean. You can find out the air quality in your room, it knows when the air quality outside might be worse – and advises you to ramp up the fan speed to ensure that your room is kept clean.

This level of control and feedback from the app makes the air purifier a truly smart device – far more so than most other air purifiers on the market. At first we were apprehensive about the lack of physical control, but it didn’t take us long to get comfortable with the app and it became a habit to check the air quality in our room.

If you don’t want to connect the purifier to an app, then you can still switch it on and off manually, you’re just losing out on all the extra data, control and help you’re getting from the app.

Coverage and Performance

We were particularly impressed by the performance of the Mi Air Purifier 2. Drawing a maximum of just 31 watts of power, the appliance works in rooms up to 400 square foot. This makes it one of the most efficient air purifiers that we’ve ever reviewed.

The coverage makes it ideal for larger bedrooms and living rooms. The speed at which an air purifier cleans the air is called the Clean Air Delivery Rate (CADR) and the unit boasts an impressive CADR of 310 m3/hr which is the fastest in its category.

Of course, you can’t place the air purifier in one room and expect it to clean all the rooms in the home. Air purifiers work by sucking in air and they are hard pressed to suck in air from other rooms, even with an open door.

On-going Costs

The lifetime of the filter varies according to usage and how polluted the air is. A person in Delhi will find that they have to change the filter every one or two months between October and February, but a person in a less polluted city might find that the filter lasts up to 6 months before it needs to be replaced.

Replacing the filter is exceptionally easy. Just open the back, pull out the old filter and replace it with a new one. Filters cost Rs 2,499 each and are available to buy on the Mi website.

Ideal Usage

The Mi Air Purifier 2 coverage is up to 400 square meters, which makes it ideal for living rooms and large bedrooms. The unit can be run in whisper-quiet mode which means the rate at which it cleans the air is lower, but makes it ideal for bedrooms.

On the lowest fan speed, the unit is far quieter than your ceiling fan and air conditioner. There is also a high speed and turbo mode which is far noisier, so you don’t want to be running it in that setting if it’s late at night in the bedroom. Even in the living room, if you’re trying to watch the TV, turbo mode might become too noisy.

Mi Air Purifier 2 Price in India

We have been constantly impressed by the unique app-based control, performance and on-going costs of the Mi Air Purifier. The price of the unit is the final icing on the cake for us. The MRP is 9,999, but you can find it for cheaper on online shops like this one.

The Final Verdict

The entire team at Which Air Purifier was thoroughly impressed by every aspect of the Mi Air Purifier 2 review process. The only downsides that we could come up with are small, such as the design isn’t very stylish like some other air purifiers. It’s very functional in nature.

Another thing someone brought up is that this is a Chinese company, but given the success of Xiaomi’s smartphones and other products in India, we don’t think the average Indian consumer cares too much about where the company is from. They do care about performance, efficiency, quality and price, and in that respect, the Mi Air Purifier 2 absolutely delivers on all four of those points.
