Indoor air quality has become an important part of modern healthy living. Two technologies commonly discussed in air purification are Traditional HEPA filtration and NCCO technology. While both improve indoor air quality, they work in different ways.

What Is HEPA Filtration?

HEPA stands for High-Efficiency Particulate Air. HEPA filters are designed to capture airborne particles such as:

  • Dust

  • Pollen

  • Pet dander

  • Smoke particles

  • PM2.5

True HEPA filters can capture 99.97% of particles as small as 0.3 microns.

What Is NCCO Technology?

NCCO stands for Nano Confined Catalytic Oxidation. Unlike HEPA, NCCO focuses on reducing odors, VOCs, and airborne chemical pollutants.

NCCO technology helps target:

  • Cooking odors

  • Smoke smells

  • VOCs

  • Formaldehyde

  • Chemical fumes

Key Difference

HEPA captures particles physically, while NCCO helps break down gaseous pollutants and odors.

bmola air purifiers combine advanced purification technologies including:

  • HEPA filtration

  • Activated carbon

  • NCCO technology

for broader indoor air purification.
