Precision Indoor Air Quality

Your home is where you heal.

Poor air quality prevents healing.

Submicronix applies physics and modern aerosol engineering to address what medicine can't and won't: the environment where patients heal.

Invisible indoor pollutants can impair healing in chronically ill patients, representing a significant unmet medical need.

For decades, indoor air quality has been defined by antiquated standards. But what about ultrafine particulates below 0.3 microns?

Physicians provide medicine and treatments,
but they don't address The Particle Burden.

Health Impact

Pollutants can exacerbate disease across the body.

Clean air is critical to the body's healing process.

Millions of Americans live with conditions that can be worsened by exposure to airborne pollutants.

Particle Physics

The smallest particles can travel the farthest into the body.

Particles between 0.1 and 0.3 microns behave differently — remaining airborne longer and traveling deeper into the respiratory system.

Particle Size Spectrum

Where the particle burden grows.

As size decreases below 0.3 microns, particles stay airborne longer and penetrate deeper.

Particle size (coarse → submicron)Particle Burden · <0.3 μm
100 μmHuman hair
10 μmPollen
1.0 μmPet dander
0.3 μmHEPA reference
0.2 μmMold debris
0.1 μmHeavy-metal dust
<0.01 μmWildfire smoke

The Invisible Environment

Addressing the invisible environment in your home.

Particles below 0.3 microns often outnumber larger particles by 10–100×.

  • Mold debris and hyphae fragments
  • Bacterial fragments
  • Respiratory aerosols
  • Wildfire smoke
  • Combustion particles
  • Heavy metals
  • Construction dust
  • Allergens
  • Textile fibers
  • Fiberglass shards
  • Indoor and outdoor pollutants

The Gap After Remediation

Remediation isn't the finish line.

Killing mold does not remove the microscopic material it leaves behind.

Remediate

Mold contamination is identified and treated.

Residual Particles Remain

Fungal material can break into much smaller fragments.

Particle Burden Persists

Residual microscopic particulate matter can remain even after visible contamination has been addressed.

HEPA · The Next Standard

The invisible environment doesn't stop at 0.3 microns.

*HEPA filters capture at least 99.97% of airborne particles 0.3 microns in diameter.

Hover or tap to expand

*ULPA filters capture at least 99.999% of airborne particles down to 0.12 microns.

Hover or tap to expand

*Both HEPA and ULPA will capture a portion of ultrafine particulates due to Brownian Motion and Diffusion.

The Submicronix Approach

The new standard for healthier indoor environments.

Traditional approaches to indoor air quality focus primarily on filtration. Submicronix applies contamination-control principles to the smaller particulate burden conventional approaches may not fully address.

The Submicronix Mission

Precision Air Quality for the Post-HEPA World.

Submicronix confronts the air quality needs of chronically ill patients. We apply modern detection, contamination-control, and filtration principles to homes where higher standards can improve the indoor environment.

HEPA remains highly effective for most residential and commercial applications. Our mission is to create healthier homes where patients can heal.
