  • Aspergillosis (niger and fumigatus)

Kills 99.99% Bacteria

  • Methicillin Resistant Staphylococcus aureus (MRSA)
  • Vancomycin Resistant Enterococcus faecalis (VRE)
  • Streptococcus Species
  • Pertussis (Whooping Cough)
  • Pseudomonas aeruginosa


SAM 400 patented UV-C technology goes way beyond HEPA filtration.

What’s wrong with HEPA filtration alone? Coronavirus are spherical particles with diameters of approximately 0.125 microns. The smallest particles are 0.06 microns, and the largest are 0.14 microns. HEPA filtration is limited to its smallest mesh size of 0.3 microns. HEPA will NOT filter COVID-19 (coronavirus) effectively. SAM’s UV-C technology captures and destroys the very smallest of microorganisms. Operating way beyond filtration, SAM eradicates 99.9995% of airborne pathogens.

EPA Guideline Laboratory Validated to KILL 99.9995% of Norovirus, the most difficult airborne virus to kill. Per EPA Emerging Viral Guidance, it is expected SAM will eliminate up to 99.9995% of all other easier to kill airborne virus including airborne CORONAVIRUS.

Because air disinfection or purification devices don’t need to be registered with the EPA, companies that make them aren’t required to disclose their efficacy data or verify their efficacy claims in their marketing materials.

Even though air cleaning devices don’t have to be registered, the EPA does have guidelines for the appropriate type and size of bioaerosol chamber in which to test. Scientific Air Management products are tested under these strict EPA guidelines and have laboratory-verifiable pathogen-killing efficacy.

Two independent, nationally recognized lab facilities (Environmental Diagnostics Laboratory and MicroChem Laboratory), using EPA guideline conditions, performed efficacy testing in airborne pathogen killing rates. The following are the tests results and compiled reports.

Per EPA guidelines, Scientific Air Management adhered to the following test protocols:

Test methods employed

Contact time (minutes vs. hours)

Type of pathogen

Killing percentage (minimum 99.9995%)

Air Disinfection Field Studies

The EPA conditions above are difficult to apply in field studies and are hard to accomplish in hospital settings.

For field studies to achieve the same efficiency in testing parameters, they should be conducted at unbiased facilities with the same scientific test conditions that eliminate all testing room variables, like:

Variable source contamination

Personnel and visitor traffic

Equipment movement

Open doors

HVAC inefficiencies

Concise testing should only include the pathogens being tested and the air management device itself within a standard size room.

The field study below, Pharmacy Compounding, is the closest on-site testing to match laboratory conditions. Due to the nature of the sealed and closely regulated pharmacy Anteroom and ChemoRoom, laboratory-like conditions were achieved as the tests were performed in these areas.

Employing the most technologically advanced EPA guideline laboratory methods, combined with modern pathogen surrogates, SAM delivers a validated kill rate for these and many more common pathogens.

EPA compliant bio-aerosol laboratory full room size chamber aerosol disinfection device study,  testing for efficacy in airborne pathogen killing rates in real-world conditions .

Tested in OR’s, ER’s, Waiting Rooms, Patient Rooms, Physical Therapy Rooms, Recovery Rooms, EVS Service Laundry Rooms, case studies conducted at 2 major Medical Centers, resulting in 50% – 70% non-viable particulate reductions in the 0.3 to 10. micron particulate range.

Four bacterial pathogens were tested to validate efficacy. A clear trend was observed in the elimination of airborne bacteria from the test chamber. The following report summarizes the lab’s findings

A Florida hospital compounding pharmacy used SAM400 to pass requirements for USP797 – CAG-009 in September 2018.

Chemotherapy and ante rooms in the hospital were out of compliance prior to the introduction of SAM’s air disinfection machine.

A case study conducted at a Major NY Medical Center proves reductions in the .03 to 10.0 micron particulate range when a SAM400 was in a typical patient room. Tests including HVAC, Central Air Handler Units, with 95% filtration  attachments, and base line coil tests were performed. Particulate reductions consistent despite HAVC inconsistency.

Microchem Laboratory  aerosol testing chamber determines the effect of antimicrobial agents on microorganisms present in the air, as bioaerosols.


The NPAC , Negative Pressure Aerosol Chamber,   measures 10′ x 10′ x 8′ (800 cubic ft.), which is the standard room size according to the EPA. Testing conducted in the NPAC simulates real world conditions of whole room disinfection devices against aerosolized  bacteria, fungi, and viruses.
