Xiaomi Mi Air Purifier Pro Review: Is It worth Your Money?

A few weeks ago, we review the Xiaomi Mi Air Purifier 3H and sharing the different prices on various stores. Today we will be reviewing the Xiaomi Mi Air Purifier Pro. I guess at the end of this review you can pick one of the Air purifiers.

Xiaomi Mi Air Purifier Pro

A glance at the body

The purifier has the form of a fairly high cuboid with rounded edges. The lower part contains air intakes in the form of quite small holes, the top conceals the drive, fans forcing air circulation, controller, pollution sensor, and outside, of course, a display showing the operating mode and air data. The air filter has the form of a toroid, the outer part of which is a mesh solids filter, and inside a HEPA and carbon filter. The bottom of the filter contains an NFC tag that identifies the type of filter and allows you to control its wear. Two buttons are used to control the purifier operation by the user – one is located on the back, the other on the upper edge. The first is needed

mainly during configuration, while the second serves as a switch and controls the current mode of operation of the device. Mi Air Purifier Pro has WiFi and works with the Xiaomi Home application that allows for more advanced configuration, so the button will probably not be needed too often.

Performance

The review unit of Xiaomi Mi Air Purifier Pro was sent to us practically ready to work – it was enough to plug in the power cord and plug it into the socket. For the sake of order, it is worth buying the filter – mine was (as it was said) ready to work, but last year I launched an identical device at my mother-in-law and there was required to remove the protective film first. During the first start, you can also connect the device to WiFi (unfortunately, only 2.4 GHz) to get the ability to control it from the Xiaomi Home application – this is not necessary, however, as the change of operating modes is also available via the button.

The basic air parameters on the display: PM2.5, temperature, humidity

After start-up, the display shows the AQI pollution level for PM2.5 particles, air temperature and humidity as well as the operating mode – this is the default Carin which the airflow is regulated based on sensor readings. In addition to automatic it is also available night mode and own mode, which performance can be set in the application (if we do not use it, it will be the maximum possible flow). There is also a colored circle around the display – the color of the light indicates the level of pollution (green, orange, red).

Xiaomi Mi Air Purifier Pro in practice

In the night mode, the device operates at a constant, low speed, which, however, is higher than the automatic setting in clean air. By default, the turbo mode causes the purifier to go to the maximum speed at which noise is very annoying – reducing the speed is possible from the application. Mostly, therefore, the automatic mode was active, in which the working person is usually quiet and trouble-free, but the performance is adjusted as needed. The problem is that the standards that the manufacturer provided for clean, moderately polluted and very polluted air are, at best, quite loose.

And yes, Xiaomi considers good air with PM2.5 up to 75 µg / m³, medium contaminated in the range 75 µg / m³ – 150 µg / m³ and very polluted above 150 µg / m³. EU standards provide for clean air at an hourly level not exceeding 25 µg / m³ … The values ​​adopted by the manufacturer are therefore not only more liberal than European, but also than Polish standards considered too tolerant. Of course, this translates into the work of automation – the efficiency of the purifier increases too slowly in relation to the needs, and unfortunately, you cannot program the thresholds in your own way.

After all, after almost two months of work, I think he is doing quite well. Perhaps it is a matter of the fact that it is the model with the highest CADR coefficient in Xiaomi’s offer, but despite tolerant standards and automation, even in situations where Airly signalled outdoor air quality at CAQI 60-70 level, at home, with the windows unsealed, indications of pollutant levels usually remained below 20 µg / m³ – typically 10-15 µg / m³, and dropped to single-digit values ​​at night.

What’s more, although the layout of the rooms at my place is not favourable for a single purifier, wandering with it in all rooms (to use the built-in sensor) showed that the air quality is maintained at a good level throughout the apartment. This is also seen in the level of natural dusting, which is clearly lower than without filtration.

Application

Because Xiaomi Mi Air Purifier Pro largely turned out to be a fire-and-forget device, it was not necessary to use Xiaomi Home often. The application provides transparent data about air, allows remote control of the purifier via the Internet, programming automatic switching on and off of the device, as well as switching modes depending on the time.

What is important, Mi Air Purifier Pro You can also easily connect to Google Home and control it using the Assistant. Unfortunately, there is no compatibility with the Home Kit. The functionality of the gate goes far beyond the control of the purifier itself; thanks to it you can integrate many devices into one working system.

filters

Down Xiaomi Mi Air Purifier Pro a basic blue filter is included. It is an E12 class filter, having about 330 g of activated carbon (earlier versions were poorer and had a lower class, as far as I know), manufactured by the Japanese company Toray. Its durability is from 3 to 6 months, depending on the intensity of use.

The offer also includes filters of other colors: purple, also E12 class, armed with an additional antibacterial layer (based on metal salts), green, E12 class, with increased efficiency of absorption of formaldehyde and other harmful gases – it is slightly thicker than the others, and its the activated carbon-containing part can theoretically be replaced independently of the rest of the filter. The last filter in the offer is black and has an increased efficiency category H13 and a slightly higher price if we can find it at all because the availability of this variant is not the best.

Summary

Xiaomi Mi Air Purifier Pro is an interesting compromise between price and possibilities. It has good performance, is convenient to use (especially compared to devices lacking even basic intelligence), offers basic monitoring of air parameters, and it can be well integrated with other Smart Home devices.

Importantly, it is a piece of popular equipment with good availability of exchangeable filters at a moderate price, and the price of the purifier itself is not excessive. Therefore, you can forgive him a very flexible approach to pollution standards and not necessarily the best-working automation, because at this price it will be difficult to find a device with similar capabilities.
