Xiaomi Smart Air Purifier 4 with 48m² Large Coverage, 400m³/h PCADR, 99.97% filtration of 0.3μm particles, 150m³/h FCADR,Alexa/Google Control, OLED Touch Screen Display

I got this air purifier to take back home to my country. The device works very well and is very quiet (compared to my old purifier). The display gives an AQI reading in big bold fonts which can be viewed from a distance. It has auto intensity control which is also helpful. Can be controlled via wifi using the mobile app which means you can switch it on before you get home.

Excellent purchase keeping room clean

I received the Global version, meaning that it supports the Xiaomi Home app and voice assistants (Alexa, Google Assistant). I primarily purchased it for use in my Kitchen to prevent cooking odours from escaping into other rooms. Here are my thoughts after about 3 days of use:- The filter is easy to install and has an RFID chip for tracking filter life and the type of filter. It came with a HEPA filter (gray) with a built-in in activated charcoal layer. It also supports filters that are compatible with the air purifier 3H (According to a xiaomi store I called based in Sharjah). The filter quality is good and doesn't have any offensive smell on first use- The top cover is removable with a screwdriver, so it's easy to clean the fan and inner housing completely- It has a negative ion generator like other more expensive air purifiers. This setting can also be turned off in the app- The fan is powerful and has good airflow- The OLED display on the front is very useful. It allows you to turn the air purifier on and off, and allows you to cycle between different modes (auto, manual). The display shows the current PM 2.5 reading, temperature, humidity, mode and wifi connection strength- The xiaomi home app is the main reason to get this air purifier. It displays all the information that the OLED display shows, allows you to operate the air purifier from anywhere with an Internet connection, and allows you to run automations if you have other Xiaomi smart productsCons:- Google assistant integration is basic. It only allows you to turn the air purifier on and off. It doesn't display any of the sensor readings- the included power cord is long (approx. 2M), but not long enough to reach the outlet near my kitchen counter- The holes on the top cover are huge and aren't covered with a mesh. This means debris can easily fall into the motor housing- The negative ion bristles are located only near the air outlet instead of near the air inlet like other expensive air purifier, so I'm not sure how useful it is- The PM 2.5 sensor is slow to react to changes since its located at the back of the air purifier- The auto mode only ramps up the fan speed above 60ppm pollution in order to stay as quiet as possibleVerdict:If you're purchasing your first air purifier, this is probably the best one at a price point of AED 700. However, it doesn't offer major improvements over the Xiaomi 3H. Further, since the 3H is around AED 490 and offers almost all the same features and CADR, it's best to go with that if you're buying multiple air purifiers for your home.

Super silent, i keep it always in my bedroom in Auto mode; but I’m not sure about the particle sensor quality. Sometime it shows 40-50 particles for no reason, then starts working really loud, that annoys me.Has my life changed drastically since using it: no, not at all.Has my psychology changed: Yes, positive way

Reliable product.Reliable seller.Product specifications and delivery time was the same as described.Nowadays there are a few non-reliable sellers in online market. We need to check seller reputation when purchasing any product online. This seller and product was ok for me.

I recently purchased the Xiaomi Air Purifier 4 and I must say, it has exceeded my expectations. Not only did I manage to get it for a fantastic price, but its overall performance and features have truly impressed me.Setting up the Xiaomi Air Purifier 4 was a breeze. The entire process was straightforward, and within minutes, I had it up and running.One notable feature of this air purifier is its negative ion functionality. While it's worth mentioning that I chose to turn it off after reading about it online.The integration with Google Home and Alexa is a definite plus. Being able to control the air purifier with voice commands adds a new level of convenience to my daily routine. I can effortlessly adjust settings and monitor air quality without even lifting a finger.I was pleasantly surprised by the accuracy of the air pollution readings. Comparing the Xiaomi Air Purifier 4's readings with those from the IQAir website, I found them to be remarkably consistent.In terms of performance, the Xiaomi Air Purifier 4 excels. For my bedroom, it efficiently cleans the air in a matter of minutes, with noticeable improvements in air quality. I appreciate how quickly it gets the job done, allowing me to enjoy fresh and clean air whenever I need it most.The only gripe I had was the plug. Initially, I was expecting a UAE plug to be included, but to my surprise, it came with a round plug instead. This meant that I had to use an adapter to make it compatible with my electrical outlets. While it was a minor inconvenience, it would have been more convenient if the purifier had come with the appropriate plug for UAE.

The device came in the factory packaging but it had the usual scotch tape on it,after several attempts to use it i felt sick every time, at first i couldn't figure out what was wrong, then i realised the filter was creating a weird dust smell that made me cough,horrible, don't buy this online, can be dangerous to breathe
