Building Air Disinfection System Designs
A final report from Yale
University's Environmental Health & Safety Team of the extensive MolecuCare
air disinfection system's performance is pending. Note references below:
Yale University is
reporting results with no dehumidification
system currently operating; "no definable airborne mold spores or
mold growth" is present from
Anderson Samplers and surface swabs. View
and on-going beta-test results indicate "a significant
reduction in airborne mold spores" from one H-10 UV air
unit operating "in extreme conditions" at Yale
University [re July News, below].
July 19th, the company began beta testing an H-10 air
disinfection unit at the Yale University School of Medicine's
Department of Bio-Chemistry and Bio-Physics "cold
room" laboratory in New Haven, CT. This is the first of a
series of prototype tests MolecuCare and Yale University
anticipate conducting together. Further
announcements are expected soon.

mold remediation unit operating inside the
Yale School of Medicine cold room (Sept 2012).
MolecuCare announces an H-10 UV air disinfection unit will
soon be placed in the
'cold room' at the Dept of Bio-physics & Bio-chemistry
laboratory at Yale University's School of Medicine in New Haven, CT in June to
combat a severe mold growth condition; mold presence and
airborne spore count will be closely monitored by the Dept.

intended primarily for intensive care,
isolation, and emergency room needs and placed
in several hospitals for long-term
early UV air disinfection machines operate at
air thru-put volumes measured up to 336 CFM, at
a velocity up to 960 FPM, with a 230 millisecond
excursion achieving bacteria, mold spore and
virus kill rates of 99.98%-plus. These H-10
prototypes are mounted on six heavy duty casters
for rapid placement as required and operate at
full capacity on a single 115-120VAC power cord.
On/Off, two-speed operation, and lamp monitoring
functions are fully automatic.

Patented Combination of Proprietary UV DISINFECTION Technologies
air over, by or under ceiling fixtures or boxed filter or
futuristic shaped devices containing ultraviolet lamps, filters,
bars, etc., either does not kill microorganisms or
only kills a "fool's-effort" number
in comparison to the total microbe population in each square foot of
indoor (or airplane cabin) air. The total airborne microbe
population is in the order of ten to over
several hundred millions times the average capture rate of
current old-school UV devices.
The billions of microbes in the air do not dock
around a device to suit the imagination, or get ‘caught’
sufficiently to create the air disinfection result required.
microbe-portion kill or filtering in a forced HVAC air duct system cannot be considered “whole building”
protection. Removing some fish in the lake is far from rendering
it fishless, and microbes are billions more abundant. These
efforts to affect microbe status in the building do not and
cannot remove the microbe challenge with the necessary
second-to-second massive-kill performance mandated by the rate
of air movement, of consistent fresh microbe generation, their
resistance and multi-billion count presence.
Module designs kill Aspergillus niger mold spores requiring
30-50 times the 100% kill-dose exposure levels of Tuberculosis
or Anthrax bacilli.
Irradiation Chamber© designs utilize a
patented combination of proprietary technologies: the unique
design allows engineers to eliminate high-pressure filtration
energy consumption while delivering true clinical standard
sporicidal air disinfection in a single pass to an entire
When the additional energy and horsepower requirements of HEPA
filters are combined with the cost of HEPA filter replacement, MolecuCare
designs cost less than using, cleaning and disposing of HEPA
filters, while eliminating microbes too small for HEPA filters
Disinfection Modules may be mounted in any
orientation. A 12 x 12 x 3 inch Module Controller
with 8 foot cable and remote ON/OFF I/O design is
proposed for each Module: optional Lamp Status LED's and
building control performance system feedback designs
available for all models. Prototype model shown.
Honeywell, upon testing early MolecuCare central UV air
disinfection methods, declares in a 'White Paper' to the
U.S. Military that "MolecuCare's UV technology
is the only known bio-terrorist technology for ready use
as a defense method".
makes this judgment based upon tests and need for
redundant kill in "hundreds to thousands of cubic
feet of continuous air passage necessary to maintain air
safety as opposed to 'HEPA' filters which decrease
airflow and allow pathogens to pass unhindered."
Honeywell reports a kill rate "thirty times
that necessary to kill Anthrax spores in a
fraction of a second exposure dose".
MolecuCare is invited to the Pentagon during the Anthrax
mail saga. MolecuCare spends a year developing Anthrax
protection for the Post Office working with the Postal
Technologies Division of Lockheed Martin.
(then named "MRAD, Inc.") consults to Ft
Detrick in removal of clean-up of deadly residual
microbes of every description and number; MolecuCare signed an Affidavit assuring
removal of all microbe life (see bottom of this page).
History of MolecuCare
Proven instantaneous destruction of viruses, bacteria
and mold spores requiring 30-50 times the kill-dose
exposure levels of Tuberculosis or Anthrax bacilli
~ The only technology capable of maintaining true clinical
standard disinfected air at any HVAC flow rate
~ Designed initially for hospital & clinical air
disinfection; economical enough for and scalable for commercial &
2001, MolecuCare patented the world's first
combination water and air disinfection system: in
2003, Canada issued a patent for MolecuCare's new
ultraviolet water sterilization technology.
favorite quote from our Founder: "An important
scientific innovation rarely makes its way by gradually
winning over and converting its opponents. What does
happen is that its opponents gradually die out and the
growing generation is familiarized with the idea from
the beginning." -- Max Planck, 1858-1947, The
Philosophy of Physics, 1936
Below left, an early (circa 1994) MolecuCare design, the "Virucidal
Chamber" dental/surgical gloved-hand sterilizer: this
design lead to development of the Prosthetix©
Article Sterilizer (right).
Above right, is the world’s only instant in-and-out, (6 second
cycle) "first surface" sterilizer (all exposed surface only).
This device does not require toxic agents as a kill-method to achieve
sterilization: article "first surface" sterilization, however
complex the surface may be, does not require high temperature energy,
but operates at ambient room temperature. Developed for use in
prosthetic and transplant surgical procedures (dental prosthetics and
burrs, heart valve, Pacemaker, bone inserts, joint hardware, etc).
This unit was tested on dental prosthetics and small articles
(syringes, glassware, and sundry hygienic, infant and personal care
articles). Extended tests at Loma Linda University School of Dentistry
acclaimed this device as "the best sterilizer performance ever
studied". Below: Excerpts from U.S. Army Corps of Engineers tests
