Which technology is identified as a method for improving indoor air quality?

• A. Microfiber rags
• B. HEPA Filters
• C. Solar panels
• D. LED lights

Answer: (B)

Improving indoor air quality relies on removing airborne particulates from the air, and HEPA filtration is a proven way to do that. HEPA filters capture and hold very small particles as air passes through them, typically removing at least 99.97% of particles 0.3 microns in size. In multifamily buildings, using HEPA filtration in central HVAC systems or with portable air cleaners can significantly reduce dust, pollen, smoke, and mold spores, which directly improves IAQ. The other options don’t address removing airborne contaminants: microfiber rags clean surfaces, not the air; solar panels generate electricity; and LED lights provide illumination. For best results, ensure proper placement and regular maintenance or replacement of filters.
