INDIANAPOLIS, June 17, 2021 /PRNewswire/ -- An ongoing study by
the University of Colorado Boulder
demonstrated that Carrier air purifiers are able to sustain
significantly reduced levels of airborne particles – between 42 -
67% lower on average – in occupied K-12 classrooms with older,
outdated HVAC equipment. According to the EPA, exposure to airborne
particles, also known as particulate matter (PM), can have a
negative effect on health, particularly to the lungs and heart.
These findings are especially notable for school districts with
aging infrastructure that are aiming to improve classroom air
quality without replacing or modifying existing systems. The
results are based on independent testing at a public school located
in Denver, Colorado. Carrier is a
part of Carrier Global Corporation (NYSE: CARR), the leading global provider of healthy,
safe and sustainable building and cold chain solutions.
The study took place in two buildings with significantly
different ages and HVAC equipment at Cheltenham Elementary School,
in cooperation with the Denver Public School District. Particulate
matter exposure comparisons were taken from an aged 1960 classroom
building and an adjacent, newer building fitted with modern air
handlers installed in 2004 and upgraded in 2019. University of Colorado Boulder engineering teams
measured how often air was being exchanged in the rooms in both
wings and then placed Carrier air purifier XL models in multiple
classrooms in the "old wing."
Prior to deployment of the Carrier air purifiers, classrooms in
the "old wing" had markedly higher PM loads than their counterparts
in the "new wing," regardless of air exchange rate – most notably
in particles less than 2.5 micrometers in diameter, which can pose
the greatest risk to health. Carrier air purifiers respectively set
to provide air flows of 500, 750 or 1,000 cubic feet per minute
(CFM) were placed in three "old wing" classrooms. The units were
found to effectively increase air exchange rate, or the rate at
which the air purifiers returned purified air to the space, and
brought the aerosol levels in older classrooms to levels at or
below those observed in newer classrooms. In addition, the air
purifiers' sound emissions during operation were sustained at or
below World Health Organization guidelines for classroom
instruction.
"As part of the layered strategy for improving classroom air
quality, the technology deployed in Carrier air purifiers is highly
effective and remarkably quiet," said Justin Keppy, President, NA Residential & Light Commercial, Carrier.
"This independent study proves that the addition of Carrier air
purifiers can significantly improve the air quality in classrooms
and provide a healthier environment for students, teachers and
staff."
The Carrier air purifier, a product offered through Carrier's
Healthy Buildings Program, combines three different filtration
technologies to create healthier indoor air. First, a pre-filter
removes large airborne particles like dust and dirt. Then, an
advanced high-efficiency filter captures over 99% of particles
across a broad range of sizes. Finally, an activated carbon filter
removes odors from the air. And with a simple plug-in set-up
process, consumers can immediately begin to filter and monitor
their air.
For larger classrooms or spaces such as cafeterias and
auditoriums, Carrier offers the OptiClean™ air scrubber, which uses
a long-life HEPA filter to remove 99.97% of airborne particles size
0.3 microns to provide cleaner indoor air. An easy way to
supplement an HVAC system without replacing or modifying existing
equipment, the OptiClean air scrubber plugs into a standard outlet
and comes in two sizes with a maximum 600 CFM or maximum 1500
CFM.
