The Xiaomi Smart Air Purifier 4 sits in our room air purifiers shortlist of air purifiers. Huge value smart purifier with OLED display. We list it because it's a model Australian buyers consistently search for and buy in this category — and at its price point it's worth comparing before you decide.
For allergies, smoke or dust, insist on a true HEPA filter and match the purifier's rated room size to yours — an undersized unit cycles the same corner of air all day. Check replacement filter prices before buying; they're the real cost of ownership.
