WarrantyOne-year limited warranty. AquaTru's product page says it will repair or replace the unit for problems with materials or workmanship.

AquaTru repairs or replaces a defective unit, but you pay a shipping and processing fee. Its help center says the warranty excludes filters, accidents, misuse and failure to maintain the unit, and covers only the original purchaser. A three-year warranty costs $49.95, but that help article doesn't name the Carafe. The help center says to register to see the full policy, and the registration page itself shows no terms.
