DOCUMENTED EFFECT
A study from a technological institute in Denmark states that the Danish-developed air purier
MAC500s eectively reduces viruses from the air. In rooms where the air purier is in use, a
more resistant virus, than corona virus, is reduced by 89 % already during the rst hour.
The study documents that the air purier MAC500s reduces viruses in the air by 89 %
in one hour. After two hours, the virus is reduced by 99 percent, and after three hours, t
he reduction is 99.9 %.
The test was performed on a bacterium infected with the MS2 virus. Coronavirus is 7-10 times
more susceptible to UV light than MS2 bacteriophages. This means that the virus on which the
test was performed on is more dicult or as dicult to degrade as SARS-CoV2 (the virus that
causes COVID-19). *
The eect has been compared to pathogens that are 3x and 5x more susceptible than the virus
MS2. The reduction will then very quickly reach 100% as shown in table 3 and gure 4. on page
9 in the full report.

Declaration of
test
and assessment
Danish Technological Institute has performed tests of the efficiency for
inactivation
virus
of the
Jimco
MAC500
air
purifier
.
The test
was
conducted
with the
unit installed in a 20
m
3
sealed
room
. T
he
efficiency
of
the
air purifier
was tested
using
MS2 bacteriophage
s
(
ATCC
15597
-
B1
)
on host
Escherichia coli
(
ATCC 15597
)
as a virus surrogate
.
The
rate of inactivation of the aerosolized MS2
was determined as the difference
between the natural inactivation rate and the inactivation rate measured during
the use of the Jimco MAC500 air purifier
. These inactivation rates w
ere
determined by sampling of the air in the
chamber over a 2
-
hour
period
. The
significant and consistent difference between t
he Natural decay test and the
Product test clearly shows a reduction of the concentration of
airborne
and
active MS2 caused by the air purifier.
Based on the measured
inactivation
efficiency
of the MAC500, the reductions in
% and in log
-
reductions are calculated and are found in the

According to Kowalski*
and Walker
†
the UV
-
susceptibility for bacteriophage
MS2 is
lower
than the UV
-
susceptibility for the enveloped virus, vaccinia virus.
Hence, the indicated efficacy of the tested MAC500 UV
-
C device to degrade the
bacteriophage MS2 will be at least similar to the efficacy against enveloped
vaccinia virus. Efficacy against v
accinia virus allows for a claim for efficacy
against all enveloped
viruses (e.g. MERS
-
CoV, SARS
-
CoV
-
1 and SARS
-
CoV
-
2)
according to DS/EN 14885:2018.
