Targeted Bipolar Pulsed Ionization: Using Electrical Charge to Target Airborne Contaminants
How TBPI applies established electrostatic principles, controlling ion polarity and timing, to target the charge characteristics of specific contaminant classes without aggressive oxidation chemistry.
AEIRO white paper
Read the paperFrom Needlepoint Bipolar Ionization to Targeted Bipolar Pulsed Ionization
A next-generation approach to contaminant-specific air treatment. TBPI builds on bipolar ionization with active polarity control and pulsed timing to reduce ion recombination and improve delivery.

Read the paperHard Ionization, Soft Ionization, and Byproduct Formation in Indoor Air Treatment
Why high-energy discharge technologies can fragment molecules and form ozone and secondary byproducts, and why low-energy soft ionization is better suited for occupied spaces.

Read the paperDo CO₂, VOCs and Atmospheric Pressure Affect the Cognitive Performance of Occupants?
A large-scale randomized controlled trial (398 adults) found no systematic negative effect on cognition from short-term CO₂ exposure up to 4200 ppm, supporting outside-air reduction when air is cleaned and recirculated.
