In order to assure the highest quality standards possible, each order is inspected for defects prior to shipping. This makes defects incredibly rare. However, if you feel that the item is defective, it may be eligible for replacement if we determine it is due to faulty workmanship or materials. Clearly Filtered offers a limited lifetime warranty. This warranty does not cover normal wear and tear, accidents, abrasion, exposure to extreme temperatures, solvents, acids, or damage caused by tampering/misuse of the item. This warranty does not cover filters. Should your Clearly Filtered item be damaged through unconventional use, we will replace it for half the current retail price plus applicable sales tax.
