Xiaomi Smart Air Purifier 4 Compact — #1 Best Seller Now $110

There is a reason this thing has over 10,000 units sold and a perfect 5.0 rating across 4,200+ reviews. The Xiaomi Smart Air Purifier 4 Compact just works, and right now it is going for $110.58 — down from $160.58.

If you have lived through even one haze season in Singapore, you already know why an air purifier is not optional. The PSI spikes, the windows stay shut, and suddenly your flat smells like a campfire. This little unit handles rooms up to around 27 square metres, which covers most HDB bedrooms and studies comfortably.

What sets it apart is the Mi Home app integration. You can monitor real-time air quality, set schedules, and control fan speed from your phone. Pair it with other Xiaomi smart home devices and you have a proper connected setup without breaking the bank.

The listing also offers the 4 Lite, standard 4, 4 Pro, and Elite models if you need more coverage for larger living rooms. But for the price, the Compact is the sweet spot for most Singapore homes. At this discount, grab one before haze season creeps back around.
