The SA-150R air purifier is designed for a 220-square-foot room, or about 14 by 15-1/2 feet. It has a clean, unobtrusive design; the housing is made of sturdy, heat-resistant off-white plastic with black and gray accents. It's designed to be able to mount on a wall, and it comes with mounting hardware. A simple control panel with only three buttons--On/Off, Function, and Time--allows for a wide range of air-purifying options: Smoke, Pollen, Automatic, four blower speeds, and a variety of timer configurations. (The timer can be set in configurations of 1, 2, or 4 hours; all be selected to total 7 hours if desired.) On Auto, the SA-150R will use its ultraviolet sensors to switch to the mode best suited to the moment. Light-up displays indicate whether the unit is cleaning dust or odor; green indicates clean, while red means it's still purifying. When the air is clean, it conserves energy by going into sensor mode.
Always unplug purifier before cleaning; use a soft cloth, dry or only slightly moistened, and towel or allow to air dry afterward. Do not allow water to drip on or enter purifier housing. After 200-300 hours of use, clean grid and filters with a vacuum cleaner; do not use water. Carbon and HEPA filters last approximately 2 years; replacements can be purchased at local dealers that carry Soleus Air products. The 115-volt Soleus Air SA-150R air purifier measures 18 by 17 by 6 inches, with a 6-foot power cord. The remote takes two AAA batteries (not included). Detailed mounting, care, and caution instructions are included. Soleus Air offers a 1-year limited warranty against defects in material and workmanship under normal use conditions. --Garland Withers
