Xiaomi Air Purifier 4 Pro with Smart APP Control & OLED Display

Probably cleans the air well. Easy set up with the app and nice controls with xiaomi home and limited control with google home. I use a humidifier with distilled water in the same room which spikes the air air purity reading 400x so the nice auto setting screams when I have humidifier on. It is quite and can turn the light off which is crucial for me. The customised setting through the app is used to make the device work on the lowest setting when humidifier is on. I feel like there is less dust but need more time to ascertain. Is a big unit but so is any brand for this power. Probably cleans the air well.

Good price for what you get (bought on sale), considering other big purifiers cost a lot more.

Very robust app for programming your air purifier. I have it programmed to only turn on at a certain air quality (and turn off once it's has cleaned the air), but also have it run on auto overnight. Once I figured out the app, the purifier runs automatically to my schedule 24/7. No need to manually touch it at all.

Not sure how it compares to other air purifiers at filtering air, but I'm happy what this one can do. So far very noticeable at getting rid of any odour. Good price for what you get (bought on sale), considering other big purifiers cost a lot more.

It’s quiet and easy to operate. Performs well to fill the room with fresh and clean air as advertised. It’s quiet and easy to operate. Performs well to fill the room with fresh and clean air as advertised.

My wife developed a dust allergy with the extensive Council earthworks happening just outside our homes fenceline so to ease her suffering I purchased the Xiaomi Air Purifier 4 Pro a month ago and have been really happy with it. I can compare it to another smaller purifier I have in another area of my home that I purchased for the same reason. The Xiaomi feels like a well-built, effective unit that runs smoothly and quietly in the background. The air quality in our home has improved considerably.

I purchased the Xiaomi Air Purifier 4 Pro a few months ago and have been really happy with it so far. While I can’t compare it to other purifiers since this is my first, it feels like a well-built, effective unit that runs smoothly and quietly in the background.

Setup was quick and easy, and despite seeing a lot of reviews saying the app doesn’t work in New Zealand, I had no issues at all — the Mi Home app connected without a hitch and has been convenient for monitoring and control.

I haven’t noticed a clear change in my allergies yet, but to be fair, it’s not allergy season and I’m often out during the day. That said, the air in the house does feel fresher and cleaner with the unit running, and that alone makes it worth having.

If you’re looking for a sleek, quiet air purifier with smart features and hassle-free setup in NZ, this one is well worth considering.

Despite 35 years in IT, I gave up on trying to get the Mi Home app on Apple to connect.

Thankfully the device can be controlled manually thru the wee front panel. Despite 35 years in IT, I gave up on trying to get the Mi Home app on Apple to connect.

Since I've used it at home, my allergies feel better. My nose not running as much as before and when I entry the house, I can feel the house less my pets smell. That's what I want exactly.

I'd give this 5 stars except the App doesn't work at all in NZ. And the Xiaomi helpdesk are not much help.

Quiet. Responds quickly to changes in air quality. Left in manual mode it potters along without the need to attend to it other than the filter/sensor cleaning. Overall, I recommend it. I'd give this 5 stars except the App doesn't work at all in NZ. And the Xiaomi helpdesk are not much help.

The product is great, silent, and works well. Downside is trying to link to the app on the phone, doesn't work for NZ which is annoying. However, no biggie as i rather do it manually.
