XIAOMISmart Air Purifier 4 Pro Filter

Q: how long its filtr is lasting in real life? is it lasting around 12month?

My original filter lasted around 10 months. I kept using it for 2 more months before replacing it for a total of 12 months. It was pretty dirty by then because I keep my air purifier turned on for almost 24 hours per day.

expensive for a repalcement

The Xiaomi Smart Air Purifier 4 Pro is a great addition to any home. It effectively filters the air, leaving rooms feeling fresh. The smart features are convenient, but the filter replacement cost is a bit high.
