Our Oak Leaf Steamer adds healthful moisture to the air and adds style and character to your wood stove. It makes a great conversation piece and gift! The steam escapes from openings where the leaves and acorns overlap. This steamer is a fun and functional way to combat dry winter air. Our cast iron Oak Leaf Steamer serves as an alternative to electric humidifiers, perfect for those with allergies and asthma. This durable, attractive steamer with removable lid holds approx. 2½ quarts of water, so it won't run dry overnight. Matte black finish inside and out.
