Air Purification

The Science of Clean Air: Medical-Grade HEPA Filtration

Indoor air quality (IAQ) is no longer a luxury—it is an essential environmental health requirement. With indoor air often 2 to 5 times more polluted than outdoor air, choosing a professional-grade purifier is vital for those spending 90% of their time indoors.

NASA & Harvard Research: True HEPA filters capture ultrafine nanoparticles as small as 0.01 μm. The Harvard T.H. Chan School of Public Health recommends high-quality HEPA units as a "layered defense" strategy to remove airborne viral particles and allergens.

Key Benefits

  • Allergen Neutralization: Traps pollen, dander, and dust mite waste.
  • VOC & Odor Removal: Activated carbon beds absorb smoke and chemicals.
  • Asthma Support: Reduces triggers to help manage respiratory health.

Buying Considerations

  • Filter Class: Demand True HEPA (H13/H14), not "HEPA-type."
  • CADR Rating: Ensure the unit is sized for your room's square footage.
  • Maintenance: Compare long-term filter costs vs. filterless tech.
