PJM Leads the Charge in NPBI Air Purification


Needlepoint bipolar ionization is a proactive air-cleaning technology that has been proven to reduce airborne particles, neutralize VOCs, and actively kill bacteria, mold, and viruses including SARS-CoV-2, which causes COVID-19. NPBI can help save energy by reducing outdoor air needs by up to 50% and requires no maintenance. Unlike traditional corona-discharge bipolar ionizers, UL-certified needlepoint BPI is ozone-free.


PJM Mechanical Contractors, Inc. has installed numerous customized GPS NPBI™ units in various HVAC system types and sizes.


How Needlepoint Bipolar Ionization Works

  • Millions of ions are released into the airstream and dispersed via the existing HVAC system

  • Positive and negative ions seek out particles and bond with them to form clusters

  • The increased mass of these clusters allows them to be easily captured by the filtration system

  • Pathogens are deactivated when the ions disrupt surface proteins

PJM Mechanical Contractors has decades of expertise in a wide array of additional IAQ products and mitigation measures including:

  • Upgraded MERV filtration

  • Humidification and dehumidification

  • Dilution ventilation (outdoor air)

  • UVGI evaporator coil treatment

  • UV light systems

  • Evaporator coil cleaning and sanitization
