Protect Your Home with a MicroAir Defense System

Reduce Risk of Airborne Viruses

Modern Air's MicroAir Defense System is an air purifying device that installs in any air conditioning or heating system. When air passes over the device, ions produced by the device reduce viruses, pathogens, allergens, particles, smoke and odors in the air, creating a healthy environment without producing any harmful byproducts.

  • Actively purify the whole house!
  • Kill mold, bacteria and viruses
  • Reduce allergens, odors, smoke and particles
  • Maintenance free*
  • No replacement parts – total cost of ownership is less than other options
  • Self-cleaning design*
  • Can be wired so you know it is always working*
  • Installs in any air conditioning or heating system

*Available on select models

COVID-19 Pathogen Test Results with MicroAir Defense System:


Human Coronavirus 229E

Time in Chamber: 60 minutes

Rate of Reduction: 90%

This test was run in a test chamber in a lab setting with the MicroAir Defense System.

A petri dish containing a pathogen is placed underneath a laboratory hood, then monitored to assess the pathogen's reactivity to Need Point Bi-polar Ionization (NPBI) over time. This controlled environment allows for comparison across different types of pathogens.

MicroAir Defense System's Needle Point Bi-Polar Ionization (NPBI) technology is used in a wide range of applications across diverse environmental conditions. Since locations will vary, clients should evaluate their individual application and environmental conditions when making an assessment regarding the technology's potential benefits.

How it works

Ions are injected into the air stream and the breathable air space, breaking down passing pollutants and gases into harmless compounds like oxygen, carbon dioxide, nitrogen and water vapor.


When the ions come in contact with viruses, bacteria or mold, their reaction decomposes proteins on the surface of these pathogens, thereby inhibiting their activity. The ions also attach to allergens like pollen and other particles like dust and dander, causing them to band together until they are large enough to be caught by your ventilation system's air filter.

This technology generates the same ions that nature creates with lightening, waterfalls, ocean waves, etc. Nature uses energy to break apart molecules, naturally cleaning the air and producing a healthy environment. The only difference between this technology and nature is that the MicroAir Defense System does it without developing harmful ozone.


The use of this technology is not intended to take the place of reasonable precautions to prevent the transmission of pathogens. It is important to comply with all applicable public health laws and guidelines issued by federal, state, and local governments and health authorities as well as official guidance published by the Centers for Disease Control and Prevention (CDC), including but not limited to social distancing, hand hygiene, cough etiquette, and the use of face masks.
