Xiaomi unveiled a new smart air purifier that would fit well for smaller rooms and tight spaces. The Chinese company's Smart Air Purifier 4 Compact comes with a small and portable form factor while picking up the cleaning functions of its larger counterparts.


  • Xiaomi launches a compact smart air purifier.
  • The Xiaomi Smart Air Purifier 4 Compact only weighs 2.2 kilograms.
  • Xiaomi's new compact air purifier is available from AliExpress for the price of ~$100.

Unlike other Xiaomi's air purifiers that have box-shaped design, the Smart Air Purifier 4 Compact features a cylindrical and table-top form. It only weighs 2.2. kg (4.9 lbs) and has a diameter of 220mm and a height of 355mm. Getting filter replacement between 6 to12 months is possible through rotating the bottom plate.

Noticeably, its display is located at the top and consists of capacitive touch controls along with a four-color indicator light like on the Smartmi cordless P2 Air Purifier. The only problem with this is you won't easily see the status without peeking at the top. Regardless, users can access the Mi Home app and alternatively see the current cleaning status. It's also compatible with smart home platforms like Google Assistant and Amazon's Alexa.

While it lacks temperature and humidity sensors that are found on the bigger Smart Air Purifier 4 series, the compact model would be able to filter out odor on top of bacterial and common allergens like pet hair and pollen.

The noise level in sleep mode is at 20dB and reaching 50dB when at max cleaning routine.

I still remember how amazed I was when I first got hold of the Nokia 3210 back when I was a kid, and it was during that time I developed my love for technology, particularly for mobile phones. I started sharing my knowledge through writing in different blogs and forums back in Nokia Nseries era. I even make videos before where I put different phones side-by-side. Today, I'm still an avid enthusiast of smartphones, but my interests have evolved into smart devices and electric vehicles.
