Air purifiers have become popular among ordinary families. However, it remains controversial whether indoor air purification improves the respiratory health of healthy adults.

A randomized crossover intervention study was conducted with 32 healthy individuals. The subjects were categorized into two groups. One group continuously used true air purifiers, and the other followed with sham air. and electric [42] air-gap covert channels have also been demonstrated over the past 20 years [18]. D. Our Contribution In this paper we introduce a new type of covert channel that exploits Wi-Fi to leak data from air-gapped networks.

The AIR-FI attack introduced in this paper does not require Wi-Fi related hardware in the air-gapped computers.
