Effective and economical, the Ultra Dome uses super-dry, moisture-collecting pellets to control humidity. The pellets cost less and collect more moisture than the flakes used by other systems. Ultra Dome's design locates pellets high above trapped moisture for peak efficiency and the over-sized reservoir enables it to work longer than other designs. Treats up to 1,800 square feet. 7-1/2"H x 5-1/2"dia. Includes 24 ounces of pellets.
