HVAC-R AIR FILTRATION IN HOMES 2
HVAC-R Air Filtration in Homes
HVAC is the technology of vehicular and indoor environmental comfort. The major
objective of this technology is to facilitate in providing thermal comfort, as well as appropriate
indoor air quality (Wang, Zhang, & Ren, 2011). Air filtration helps in improving the health of
patients with respiratory disorders. The Environmental Protection Agency has outlined that
people's health is tremendously affected by indoor air quality (Herberger & Ulmer, 2012). It has
been found that using germicidal UV light is the best method of improving indoor air quality.
UV light helps in reducing allergy symptoms because it has high energy that can kill
microorganisms (Burroughs & Hansen, 2011). There are several allergens such as dust mites that
are found in people's homes. These allergens can be destroyed by UV light. Dusting and
maintaining home cleanliness cannot eliminate allergens completely because some are still in the
air. UV light eliminate the allergens in the air, ensuring that the room has no allergens.
UV light protects the indoor environment from the mold (Herberger & Ulmer, 2012).
Mold is one the major health issues associated with indoor environments. Allergic reactions can
be triggered by mold spores when people are exposed to such environment. These reactions
range from mild to severe. Exposure to mold spores for an extended period may result in chronic
lung conditions. Mold spores in the air are easily killed by UV light. Eliminating mold spores
ensure that people do not inhale this toxic fungus.
UV light plays a vital role in improving people's heath by killing germs (Herberger &
Ulmer, 2012). During the flu and cold season, germs spread everywhere including the indoor air
environment. The germs include bacteria and viruses that cause diseases. People are vulnerable
to getting sick when exposed to these germs. UV light helps in killing these pathogens in the air.
