The Good Housekeeping Seal is symbol of assurance and reliability to consumers for over 100 years. When an item earns the Good Housekeeping Seal, it has been rigorously assessed by the Good Housekeeping Institute and performs as promised. We stand behind every GH Seal product with a two-year limited warranty, offering repair, replacement or refund up to $2,000. The Good Housekeeping Institute is a state-of-the-art consumer testing facility staffed by engineers, chemists, researchers and other scientists.
