HEPA air purifiers are designed to trap small particles in the air, but how effective are they really?

Understanding HEPA Filters

HEPA (High Efficiency Particulate Air) filters are known for their ability to remove at least 99.97% of particles that are 0.3 microns in size. This efficacy includes allergens, smoke, dust, and other airborne particles.

Q&A on HEPA Air Purifiers

• Q: How do HEPA air purifiers work?
  A: They pass air through a dense filter which traps particles.
• Q: Are they effective against viruses?
  A: Yes, HEPA filters can trap many viruses and bacteria.
• Q: Do they remove odors?
  A: Not effectively; additional activated carbon filters are needed for odors.
• Q: Maintenance requirements?
  A: Filters should be replaced typically every 6-12 months depending on usage.
• Q: Can they really improve indoor air quality?
  A: Yes, they can significantly reduce airborne contaminants, improving overall air quality.
• Q: Are HEPA air purifiers noisy?
  A: Noise levels vary by model but many operate quietly.
• Q: Are there any health benefits?
  A: Yes, they can alleviate allergies and improve respiratory health.
