More than 25 million Americans, including many children, suffer from
asthma and allergies, causing them to miss work or school and costing
millions of dollars in healthcare expenses1. To help reduce
exposure to allergy and asthma triggers, many patients implement
lifestyle changes, such as washing bedding frequently, using
hypo-allergenic pillow cases and HEPA vacuum cleaners, and using
high-efficiency air filters in forced heating and cooling systems. While
some may question the effectiveness of these changes, a new study
published in the August issue of the Journal
of Asthma found that using a high-efficiency air filter with a
MERV rating of 12 or higher can effectively reduce indoor levels of
common airborne asthma and allergy triggers.
The study2 was designed and conducted by Environmental Health
& Engineering, Inc., (EH&E)
of Needham, Mass. EH&E professionals evaluated the effectiveness of six
types of residential air filters at capturing four types of microscopic
particles found in indoor air of homes - cat allergen, respiratory
virus, and indoor and outdoor fine particulates - all of which can
affect indoor air quality and contribute to cough, shortness of breath,
wheezing, and other asthma symptoms.
"While other studies have addressed ways to manage asthma at home, this
is one of the first to evaluate the use of high-efficiency filters as an
important part of the solution," said Dr. David L. MacIntosh, Chief
Science Officer with EH&E and Adjunct Associate Professor at the Harvard
School of Public Health. "Some asthma interventions can be quite costly,
yet this study demonstrates that spending an extra $50 per year for a
higher-efficiency filter may have significant impacts on levels of many
airborne triggers in the home."
While effective asthma interventions should include several elements,
study results show that the Filtrete
Healthy Living Ultra Allergen Reduction and Filtrete
Healthy Living Ultimate Allergen Reduction 1-inch air filters
captured more than 50 percent of asthma and allergy triggers in a
typical home. These filters also were found to be more than nine times
as effective as standard fiberglass filters.
