Doctors at

the Division of Allergy and Immunology at the University of California

at Davis, one of the world's leading allergy research institutions, recommend

frequent deep cleaning of the home, including vacuuming at least twice

a week. According to a recent U.C.-Davis clinical study, using a built-in

central vacuum system offers the best means to remove household dust,

dust mites, pollen and pet dander, the leading triggers of allergic rhinitis.

The U.C.-Davis study participants used Beam Serenity Series Central Vacuum

Systems during the clinical study.

"A central

vacuum system is up to five times more powerful than a conventional vacuum,

so it captures far more allergens," said John Coghlan, president

of Beam Industries. "A central vacuum also pulls all of the contacted

material out of the living area to a canister in the garage or basement

so it won't recirculate in the home."

Doctors at

the U.C.-Davis also offer other recommendations to reduce the severity

of allergy symptoms including:

Maintaining

relative humidity at less than 50 percent. Dust mites cannot survive in

a low-humidity environment.

Cleaning and

maintaining forced-air heating systems and air conditioners at least once

a year.

Dusting furniture

with a damp cloth rather than a dry one.

Installing

and using bathroom and kitchen exhaust fans that are vented to the outdoors.

Enclosing

pillows, mattresses and box springs with mite-proof coverings and washing

bedding at least once a week using water at least 130 degrees.

Replacing

fabric-upholstered furniture with leather upholstery or with furniture

made of plastic, wood or metal that won't trap allergens.

Experts also

advise patients to consult their doctor to determine the appropriate regimen

for managing allergies or asthma, and notify the doctor of any change

in symptoms.
