The Xiaomi Smart Air Purifier 4 Pro is the latest air purifier released by Xiaomi in the Malaysian market. Being part of the Series 4 lineup, this Pro variant would be considered the flagship of the bunch, and we’re here to review if it’s any good. But before that, let’s take a look at the specs, shall we?

|What’s In The Box?||Xiaomi Smart Air Purifier 4 Pro|
In terms of design, there’s not much changes in this department. Don’t fix what’s not broken, right? The Xiaomi Smart Air Purifier 4 Pro still uses the tall, spherical tower design, with the sides on the bottom wrapped with perforated holes for dirty air intake. The new OLED display is placed on the front for easy monitoring, and the output air vents are positioned up top facing upwards.
On the back, that’s where you’ll find the PM2.5/PM10 dual-effect laser sensor. That is also right above the tray slot where the HEPA filter is installed. On the bottom, there’s a round base that is lined with rubber, along with the power port.
There’s not much to shout about the design, except that it looks aesthetically pleasing with the matte white finish. It’ll be easy to place and match it into any living space you’re in.
Xiaomi has been known not just for their smartphones, but also their smart home appliances, and the smart air purifiers are one of the pioneer products of that portfolio. Owning a Xiaomi Smart Air Purifier 3 Pro myself (its predecessor), I’m already familiar with the Xiaomi smart home ecosystem. Comparing between the two, I’d say the user experience is somewhat similar, which is good because there’s nothing new or complicated to learn.
Setting up the Xiaomi Smart Air Purifier 4 Pro was an easy process – take it out of the box, plug in the power cord, unwrap the packaging on the HEPA 13 filter, put it back in, and turn it on. Just like that, you’ve got your new Xiaomi Smart Air Purifier 4 Pro all set to go. The next step is to install the Xiaomi Home app and pair the purifier to your device. This gives you even more control over the purifier, allowing you to do things like performing firmware updates, setting up schedules, configure home automation, routines and scenarios, and more.
With the app as well, you can monitor detailed real-time information about the air quality in your living space. There’s also info like temperature, humidity levels, and estimated remaining days for your HEPA 13 filter. This is really useful so that you will know exactly when the time is right to change filters. No stress, no technical knowledge needed, as the app does it all for you.
You can also share the Xiaomi Smart Air Purifier 4 Pro with other family members so they may control it remotely as well. Combining it with other Xiaomi smart home accessories, it can be fully automated depending on the air quality, temperature, or humidity in the room. That’s what I like most about the Xiaomi Smart Air Purifier 4 Pro. Set it up once on the device and in the app, and it basically runs itself throughout the year.
Performance And Maintenance
Having three cats at home, that also means three litter boxes. Currently, I’m staying in a 650 sq ft. unit with an open style layout, and these litter boxes mean serious business when it comes to dirt particles and smell. Because I don’t want my cats jumping out of the windows to their deaths, I keep the windows closed 99% of the time.
Having used the Xiaomi Smart Air Purifier 4 Pro for a month now, the first thing I realized is a drastic drop in terms of smell. The stench coming from the litter boxes aren’t as strong, and from a distance I don’t smell it that much anymore.
I’ve tried vaping directly and indirectly to the purifier, and it takes less than 3 seconds each time to kickstart the fan and start the purification process. Its response is near instantaneous, and the purification process takes about 10 seconds. For when I’m cooking, even with the cooking hob on, the purifier does a consistent job in purifiying the smoke that escapes the cooking hob. Even after I’m done, it still runs for 10 minutes to ensure the air is truly clean.
The true core of the Xiaomi Smart Air Purifer 4 Pro is its filtration system, and it’s using a three-in-one filter. That consists of the main filter, Xiaomi’s own high-efficiency filter, as well as an activated carbon filter that traps smell. These filters work together to eliminate 99.97% of 0.3μm particles. Not only does it clean up dust and smell, it also eliminates pet hair, pollen, smoke, dander, and cotton fibre.
Not only that, to clean up the room’s air, the Xiaomi Smart Air Purifier 4 Pro has a Particle Clean Air Delivery Rate (CADR) of up to 500m³/h, and is able to release 8330L of clean air per minute. That’s a lot of coverage in a short amount of time, so the smaller the room, the faster the purification process.
In terms of noise, the Xiaomi Smart Air Purifier 4 Pro barely makes a sound, except for when the fans kick in to purify the air. Even when it’s on high fan speed mode, sound is tolerable and not at all irritable to the ears. If you want it to be even more hush, turn on Night mode, and it will turn off the OLED display, and lower the noise levels even more, working silently in the background – you won’t even remember it’s there.
The OLED display is bright and colours are sharp. At a glance, I could easily tell the air-quality status from the colour indicator bar. It is also placed in an optimum position, where I can see it regardless if I’m standing up or sitting down.
When it coms to maintaining the Xiaomi Smart Air Purifier 4 Pro, the usual will suffice. From time to time, give it a good wipe down and vacuum the air vents and perforated holes. Take out the HEPA filter and give it a good brush and vacuum as well. When it’s time to change the filter, simply take it out and replace it with the new one, and you’re good to go for another year.
The top grille is removable by screw, so you can remove it to give the fan blades and air ducts a good clean. The screws also prevents your child from opening or accidentally injuring themselves from the fan blades.
The Xiaomi Smart Air Purifier 4 Pro was made to conquer and purify larger spaces, from living room to master bedroom, it’ll work wonders to clean the air for your loved ones. It’s easy to use, worry-free, and you don’t have to pay attention to it much, really. Just sit back, relax, and let the purifier do its own thing in the corner of your house.
