DiscussionSTAS is able to kill and trap the bacteria with higher efficacy and performance. In addition, it also aids to sleep and breathe better, keeps the body fresher, and increases the oxygen level in brain for better functioning. The combination of these layers can make indoor atmosphere clean and free from all pollutants. The pollutants are trapped by the combination of impaction, interception, and diffusion mechanism. The larger particles follow the curved contours of the air and reluctantly attach to with another, this effect is called impaction, the mid-range particles are eliminated by interception process, and finally the particles of size < 0.3 μm are eliminated by diffusion process.
