Satisfy Customers—including their doctors, lawyers and adjusters.

Remediation is evolving. Source removal is recommended over the use of antimicrobials, and odiferous chemicals that mask problems are undesirable, portable HEPA filtration is fraught with challenges in terms of engineering appropriate air flow and testing for leaks, and medical professionals have developed sophisticated testing methods and biomarkers that point to toxins in the environment.

AeroSolver is proud to offer the remediation industry a new, sophisticated yet simple technology for cleaning indoor air.

Active Capture

HEPA filtration is only effective under specific air flow conditions, which are challenging to achieve in remediation environments. Rather than rely on air flow to push particles through a filter, AeroSolver fills the volume of the room with a particle-capturing fog. This method employs similar physics utilized for years by the Pollution Control industry.  It is ideal for ever-changing remediation environments. Typical features such as corners and fixtures present a challenge for air flow dependent methods like HEPA filtration. AeroSolver evaporates slowly so particles do not re-aerosolize during damp wiping, yet does not permanently seal to surfaces.

  • Use AeroSolver to ensure no particles are left behind
  • AeroSolver Pure can be used with chemically sensitive clients
  • Faster and more economical to use than air scrubbers

One of the biggest misconceptions is mold remediation is successful if you get good spore trap air sample results.  This test method can’t be used to identify small microbial fragments that are nondescript when viewed with a light microscope at the highest magnification. For health effects, smaller particles are more dangerous since they can penetrate the lungs and blood stream more efficiently.  The diameter of the alveolar pores in the plural lining of the lungs is approximately 5 micrometers. Conidia (anamorphic spores) from various species of Penicillium and Aspergillus are generally 2 to 5 micrometers in diameter with shapes beingcircular (spherical)  to slightly oval or ovoid. Stachybotrys and Chaetomium produce larger conidia with non –spherical shapes (football shape to cylindrical for Stachybotrys and a lemon drop shape for Chaetomium). Conidia for Alternaria have a bowling pin shape and can exceed 40 micrometers in length. 

Small particles are harder to control in the air since they are not subject to gravity as much as larger mold whole spores.  ISO cleanrooms are rated by their cleanliness for particles in the air as measured by a laser particle counter.  Depending on the density of the particle, Brownian motion starts occurring at approximately 0.5 micrometers or slightly larger than an endospore from Bacillus bacteria at 0.3 micrometers.  Anothersize range for cleanrooms is 0.1 micrometersor 100 nanometers (Influenza virus).  The smaller the particle, the harder it is to clean from the air. The problem is air turbulence creates swirls and eddies to which in turn creates chaos for cleaning the particles from the air.  Laminar airflow for cleanrooms was invented by Sandia Laboratories in 1961 for the nuclear program.  In today’s unidirectional cleanrooms, HEPA filtered air is supplied from one side or the ceiling and pulled by exhaust systems opposite the supply wall or ceiling.  The airspeed must be 60 to 120 feet per minute or you will have areas of airborne contamination from submicron particles. HEPA filtration is only effective under specific air flow conditions, which are challenging to achieve in remediation environments with portable devices.

Overcome this problem after you do demolition and preliminary surface cleaning.  Use AeroSolver product with the NAMs turned OFF.  Immediately start wiping surfaces. HEPA vacuuming should always occur before any final fogging to avoid cross-contamination.
