Hoover SilentAir 4000 Ionizing Air Purifier

SilentAir Purifier - Advanced Electrostatic Technology traps many tiny contaminants that HEPA Filters can miss - Helps Purify the Air

Breathing the cleanest air possible is essential to the health and well-being of asthma and allergy sufferers, infants, and the elderly. Hoover’s SilentAir 4000 purifies air without a fan or filter; instead, it circulates negative ions that attach themselves to particles of dust, dander, mold, bacteria, and other pollutants that are commonly found in home and office environments. Instead of letting those polluting particles fall to the floor, the SilentAir traps them on its positively charged Dielectric Collection Sheet. Even the minutest particles that escape most air filters are trapped by this system. As a result, air in rooms up to 500 square feet is conditioned, cleaned, and deodorized as irritants and allergens disappear. Virtually silent, the fanless purifier will not disturb sleep or create drafts. And, with no motor or moving parts, the purifier requires only 4 watts of power to operate, resulting in power costs of less than $4 annually. Six dielectric colleting sheets come with the purifier, which should be changed every three to four weeks. A three-year warranty covers the purifier against defects. --Ann Bieri
