Air Oasis Photocatalytic
UV Test Data
Conducted by an independent lab.
Coverage
over a six day period in an average 3000 sq. ft. single level home.
Petri-dishes were placed in the furthest corner of every room daily and tested
over a six day period. Several tests were conducted with varying amounts of
contaminants. More time was required to achieve the total 3000 square foot
coverage as contamination levels were increased. With the Air Oasis 3000 it's
not a matter of how many square feet can be covered, but more a matter of
time. A timeline for complete coverage is illustrated below.
Note: This
model of a home had no fans or air conditioning unit to circulate air. The
air purifier did all the work in this controlled environment.

Test Procedure |
The device was operated as
directed under normal household conditions. Five replicate air samples
were drawn from an area 13 feet from the device and about 3 feet above
the floor at intervals of 8 hours, 30 hours, 54 hours, 102 hours, and
150 hours after start. Standard Petri Dishes were inoculated at each
sampling interval. The Air sampler was calibrated to deliver 100 liters
of air in one minute and 500 liters of air in five minutes. Inoculated
plates were returned promptly to the laboratory for incubation and
counting. There were four tests run five different times in different
petri-dishes in different places throughout the test house.

Summary |
After four days:
Test 1 Mold: 97.7% reduction
Test 2 Yeast & Mold: 90.9% reduction
Test 3 Mold: 77.0% reduction
Test 4 Bacteria*: 34.5% reduction
*Note: Bacteria tests in
homes with low ambient bacteria levels will show low percentage drops.

Ozone Levels Lab Test For Air Oasis Air
Purifier
Testing the
new AHPCO™ Cell in an HVAC duct. The ozone levels within the duct were .02 ppm
which is the same as forest air. The ambient levels within the room outside
the duct were .01 ppm. With the new AHPCO™ Cells, oxidation is performed by
super oxide ions, hydroxide ions, and hydro peroxide ions in air vapor rather
than strong and dangerous ozone.

The
Petri-plates after a 24 hour treatment with the air purifier. Note the
reduction in number of colonies compared to figure 1 (Control, No treatment
with air purifier).
It was also
evidenced that the Petri-plates placed closer to the distance to the air
purifier (1ft. and 2 ft.) produced least number of colonies after 24h., 48h.
and 72 hours of treatment of the indoor air with the air purifier. Figure-3
shows the level of infection after 24 hours with distances 1 ft, 2ft. and 4
ft. away from the air purifier. There was very minor trace of inoculums from
the Petri-plates from 1 ft. or 2 ft. and 4 ft. distances after 24 hours of
treatment of the room air indicating thereby definite reduction of the
microbial aeroallergen in the room air. After 72 hours of treatment of the
indoor air with the air purifier there was almost no micro flora or propagules
left in the indoor air since there was no microbial colony produced on the
Petri-plates. All the experiments were carried out with setting at High in the
air purifier. Figure 1 shows the Control plates without any treatment. All the
3 Petri-plates from the set up of 1ft, 2ft and 4 ft show vigorous growth of
the microbial colonies after incubation in an incubator at 37 degrees Celsius.

Effect of air purifier after
different periods of exposure on the number of microbial colonies.
From the
figure-2 is a graph on the distribution of the number of microbial
colonies before and after the treatment of indoor air with the air
purifier, it is very clear that there was a gradual reduction in the
number of microbial (bacterial and fungal) colonies with greater interval
of exposure with the air purifier. |

Effect of
treatment of air purifier on the concentration of indoor aeroallergen
concentration.
The Petri plates from the set up of 24 hour treatment with air purifier
from distances 1ft, 2ft and 4 ft from the air purifier showed no
significant microbial growth. At the distance of 1 ft no microbial colony
was recorded on the Petri-plate while the Petri-plates from 2 and 4ft
showed very minor trace of inoculums. This figure shows the distribution
of the aeroallergen count after the treatment of the room air after
24hour, 48 hour and 72 hours. After 72 hours of treatment there was almost
no aeroallergen left closure to the air purifier. |
