Description
Zhongna Fu and seven colleagues tested in 2026 a new hospital air cleaner that uses a high-oxygen membrane, comparing it with a plasma air cleaner already in use. Natural airborne bacteria served as the test organisms, and trials ran in wards both empty and occupied, so the team could see how real ward life changed performance. They also checked whether room size, temperature, humidity, starting bacterial load, or staff movement altered the result.
With no one in the room, the membrane machine killed 88.4 percent of airborne bacteria, clearly above the plasma machine's 82.5 percent. Once the ward was occupied, the gap vanished, at 80.0 percent against 78.7 percent, a difference too small to be statistically meaningful. Room conditions and staff activity did not measurably change the membrane machine's performance in these tests. The authors conclude it beats plasma cleaning in empty rooms only, and it cannot yet stand alone against airborne infection.
