Xiaomi Air Purifier 4 with Smart APP Control & OLED Display

I bought this because my partner suffers from a pollen allergy. We think the unit has made a difference, but it's hard to tell for sure because this unit doesn't measure PM10 (pollin) sized particles. It only measures and responds to PM2 sized particles (urban pollution) - so when on auto, it always run at the lowest speed. There is also the Xiaomi PRO model, which does measure PM10 particles, but has a bit bigger footprint. I also considered the Samsung AX34T, which does measure PM10, but it has a lower CADR rate, a bigger footprint, and much more expensive filters. The unit requires 200mm of free space around ALL sides, so make sure...view more I bought this because my partner suffers from a pollen allergy.

I also considered the Samsung AX34T, which does measure PM10, but it has a lower CADR rate, a bigger footprint, and much more expensive filters. The unit requires 200mm of free space around ALL sides, so make sure you allow for that. The front-controls are easy to understand. The Android app gives you more control, such as being able to turn off the negative ion generator, set a custom fan speed according to room size, or program on/off/speed changes for different times of the day. At the sleep setting it's relatively quiet, but there is a noticeable, fan/air-movement rustling sound which is pretty easy to get used to. At the lowest manual fan-speed (probably similar to sleep mode speed), the unit reports it can fully cope with a room of 5-9 square meters, it's pretty quiet up to 7-13m, but the noise lifts substantially after that. If run at top fan speed, you probably wouldn't want to be the same room with it. It feels like it's making a difference, it's easy to control, fits into the space, isn't too expensive, the consumables are not too expensive, it looks nice in the rom, so we're happy with it.

I’ve been using the Xiaomi Air Purifier [Model] and I’m very happy with it so far. It was easy to set up, the Mi Home app is convenient for monitoring air quality, and it runs very quietly on night mode.

I’ve noticed a big improvement in air freshness, especially during allergy season — less dust and stuffiness. The design is minimal and the filter is easy to replace by looking at the instructions (Not need replacing yet)

Overall, it’s great value for money and does exactly what I need. Highly recommend if you want cleaner air at home! I’ve been using the Xiaomi Air Purifier [Model] and I’m very happy with it so far.

I bought this for my double bedroom and it's bigger than I was expecting it to be, but it's designed for much larger spaces.
Hardly noticeable sound running on lowest level, and it can turn over all the air in my room in about half an hour at that rate.
Bought this to remove mould spores, dust mites and other allergens and it certainly helped, though I also had to throw out a duvet and some pillows before my allergies cleared up completely.
The build quality is rather good, better than I was expecting, everything clips together nicely.
After I bought it, I saw one of a different brand that was much smaller and less than half the price, but I'...view more I bought this for my double bedroom and it's bigger than I was expecting it to be, but it's designed for much larger spaces.

House smells better after using this. Not sure yet how effective it is with tackling dust as I still find myself sneezing (although less often than before) and I have it running at least 8 hours a day.
