Every room must have a medical-grade purifier.

The Silent Siege: A Physiological Report on Air Pollution
We often mistakenly believe that air is transparent, ethereal, and an unconditional public resource that we can take for granted. But under a microscope, that seemingly pure air may be a cocktail of heavy metals, polycyclic aromatic hydrocarbons, nitrates, and sulfates.
Air pollution is not merely the grayness outside the window; it is a round-the-clock 'microscopic invasion' targeting the human defense line.
1. Breakthrough: When particles penetrate the defense line
The human body has a sophisticated defense system: nasal hairs can block large particles of dust, and the cilia in the trachea can expel foreign objects through coughing. However, this system is nearly ineffective against PM2.5 (particles with a diameter of less than 2.5 micrometers).
