Allergy-resistant pillowmaker PureZone raising $3 million

MINNEAPOLIS, Minnesota — PureZone Technologies is raising $3 million ahead of the November launch of its product: a filtration system that also blows away allergens and other particles through a pillow.

The company’s product is a pillow attached to a filtration device that sucks in surrounding air, removes particles via a HEPA air filter and then pushes the cleaned air through the pillow. The company in July announced plans to raise about $5 million, though its recent SEC filing is $2 million less than that figure.

The pillow system was test-marketed last year in a Minnesota hotel and PureZone went so far as to conduct a research study with the state’s Clinical Research Institute in the hope of winning over skeptical allergists.

PureZone’s Web site said it will officially launch the product in November. Each pillow system costs almost $400.
