What Is Bipolar Ionization?
A Guide to Plasma Air’s Soft Ionization

Cleaner, Safer Indoor Air

Plasma Air Bipolar Ionization

Around the world, commercial buildings and residential homes face a hidden challenge - indoor air quality.

Plasma Air’s soft bipolar ionization (BPI) technology reduces airborne particles, pathogens, odors, and VOCs, safely and continuously. The technology is designed to restore healthy indoor air via equipment installed in HVAC system.

What Bipolar Ionization Does

Let's review how soft ionization works to clean the air of pollutants.

Step 1 - Ions Cluster Airborne Particles

Ions group small particles into larger clusters.

Step 2 - Larger Clusters Improve Filtration

Improved filtration efficiency without upgrades.

Step 3 - Pathogens Are Inactivated

Viruses and Bacteria are disrupted at the molecular level.

Step 4 - Odors Are Neutralized

Odor molecules are broken apart.

Step 5 - VOCs Are Broken Down

Hazardous chemical compounds are reduced.

What Bipolar Ionization Removes From Indoor Air

Proven Reduction of Key Air Pollutants

Viruses &
Bacteria

Ions disrupt harmful microorganisms to reduce viability.

VOCs &
Chemicals

Breaks down chemical pollutants and harmful gases.

Mold &
Spores

Reduces airborne spores that trigger allergies and asthma.

Fine
Particles

Clusters tiny particles (PM2.5) so filters can capture them.

Odors &
Gases

Neutralizes organic odors and chemical smells.

Soft ionization reduces airborne pathogens, PM2.5, allergens, VOCs, and odors. We help building owners meet clean air goals, reduce complaints, and support occupant health. Visit our research library for more.
