I use the Smart Air 4 for small rooms and Smart Air 4 pro for big rooms. I think there might be a newer model out, and I always get the global version. Been using this brand for years.
I just bought the Xiaomi Air Purifier 4 Pro and it’s very good it has a higher CADR for bigger rooms, better sensors for the PM2.5 + PM10 detection and faster air cleaning from my research. The regular 4 still handles PM2.5 fine but is more suited to smaller rooms.
Robo vacuumed, daily wipes, air purifier, humidifier (moister in the air to capture and drag down dust).
Even closing windows 24/7 will not help cause by law apartments and homes must have a ventilation system that lets air flow and cannot be blocked. Look for a small square plastic panel near balcony entrance.
I run Xiaomi Smart Air Purifier 4 Pro and have it run with my Home Assistant. It’s on almost 24/7.
Looks interesting, but not as widely available as a Xiaomi.
The Xiaomi 4 Pro and the Smartair SA-600 appear to have the most directly comparible CADR ratings (500 vs 508 claimed)
Prices are from Lazada Xiaomi store or WEDO air, an official supplier of SmartAir in Thailand
[SmartAir SA-600 Review](https://housefresh.com/smart-air-sa600-review/) Cost: 10900
[Xiaomi 4 Pro](https://housefresh.com/xiaomi-4-pro-review/) Cost 7010
SmartAir Replacement Filter cost (Requires 2X HEPA plus 2X Carbon) 990+890= 1880
Xiaomi Replacement Filter cost (1 HEPA, with built in Carbon filter) 1349
The SA-600 is fully manual, basically a box fan with a filter.
The Xiaomi has an air quality meter and an auto mode.

Durable, effective for allergens/odors, but loud on high.
