Xiaomi unveiled its latest lineup of air purifiers in the “Smarter Living 2023” event held last week. So let’s have a look at the new Xiaomi Smart Air Purifier 4 series (including Smart Air Purifier 4 Lite), along with their features, availability, expected price in Nepal, and more.
Xiaomi Smart Air Purifier 4 series overview:
In terms of design, Xiaomi’s new air purifiers have the same rectangular shape as their predecessors. There’s a circular OLED touch display that displays information such as real-time PM2.5 (Particulate Matter) level, temperature, humidity, and WiFi connection. This button can also be used to switch between modes such as Sleep, Auto, Favourite, Low, Medium, and High.
Three-layered filtration system
They also include a three-layer filtration system, which includes a primary filter, a true HEPA filter (with anti-bacterial and anti-viral coating), and an activated carbon filter. According to Xiaomi, the Smart Air Purifier 4 series can remove up to 99.97% of 0.3μm airborne particles. For reference, pet hair, pollen allergens, dust, smoke, dander, cotton fiber, etc. comes in the 0.3μm particle range.
Furthermore, Xiaomi has obtained TÜV Rheinland Allergy Care Certification for the Smart Air Purifier 4 series. They also function as an odor eliminator, removing VOC (Volatile Organic Compounds), formaldehyde, toluene, cooking fumes, and other odors. Unlike the “Lite” variant, the regular Air Purifier 4 has negative air ionization too, which releases negative ions for even cleaner air.
