1. Advanced Filtration System: The air purifier typically incorporates a comprehensive filtration system designed to capture and remove fine particles and gases present in second-hand smoke. This system often includes a pre-filter to capture larger particles, a HEPA (High Efficiency Particulate Air) filter to trap smaller particles, and an activated carbon filter to absorb odors and volatile organic compounds (VOCs) associated with smoke.

2. HEPA Filtration: The HEPA filter is a critical component for effectively capturing microscopic particles commonly found in second-hand smoke, such as tobacco smoke particles, allergens, dust, and pollen. It removes up to 99.97% of particles as small as 0.3 microns in size, ensuring cleaner and fresher air.

3. Activated Carbon Filter: The activated carbon filter plays a vital role in adsorbing and neutralizing smoke odors, VOCs, and other unpleasant smells present in the indoor air. It helps eliminate lingering smoke smells, making the air purifier particularly effective in combating second-hand smoke.

4. Smoke-Specific Sensors: Some models of air purifiers designed for filtering second-hand smoke may feature specialized smoke sensors that detect elevated levels of smoke particles in the air. These sensors automatically adjust the purification settings to provide optimal air quality and efficiency in removing smoke pollutants.

5. Coverage Area: Air purifiers come in various sizes and capacities to accommodate different room sizes and air purification needs. It's important to select a model with an appropriate coverage area to ensure effective filtration of second-hand smoke in the desired space.
