Landmark Clinical Study Shows Reduced Allergy Symptoms Using New HEPA Filtration Pillow Device

EDEN PRAIRIE, MN--(Marketwire - May 5, 2010) -  Allergy and asthma sufferers who participated in a recent clinical study experienced reduced morning and nighttime symptoms and slept more soundly using an innovative device that creates a clean "air bubble" around their pillow. The study, which will be published in the peer-reviewed Annals of Allergy, Asthma and Immunology today, focuses on the effectiveness of the PureZone HEPA Sleep System, a first-of-its-kind air-purification device developed by PureZone Technologies.

PureZone uses a HEPA filter to remove more than 99.9 percent of allergens surrounding the mouth and nose of a sleeping person. A small, quiet fan unit draws in contaminated air, purifies it and then blows the pure air through a special pillowcase to create a protective, allergen-free breathing zone for sleep.

The results of the study showed that use of the PureZone HEPA Sleep System as a single therapy significantly improved nighttime and morning nose and eye allergy symptoms for 89 percent of participants. The device also improved quality of life for allergy sufferers, without the need for additional measures to control the bedroom environment.

"We have been able to support that the PureZone Sleep System significantly reduces nose and eye allergy symptoms while improving quality of life," said Dr. Allan Stillerman, the board-certified allergist who conducted the study at the Clinical Research Institute of Minneapolis. "This is the first environmental control device clinically proven to do that."

The trial compared the pillow-based filtration device to a placebo device -- an identical-looking device that lacked filtered airflow to the breathing zone. Researchers collected a rating of congestion, itching, sneezing, secretion and eye problems each day when individuals woke up and went to bed. Breathing zone particles were also assessed and a Quality of Life Questionnaire was completed weekly.
