Reviews split between filters that work and repeated product problems. Many customers say refunds never arrived, charges were repeated, and support did not respond. Others mention quick delivery and better-tasting water. Most complaints center on billing and returns.
Examples from available reviews (Nov 2018 – Feb 2026).
Return process was lengthy, return at expense, and refund was not issued.
“BEWARE OF THIS COMPANY.”
Received unauthorized auto-reorders and had leaking filters; refund seems unlikely.
“Found out my name was on an automatic reorder list.”
Filter works well, easy to install, and I'm happy after repeat purchases.
“Works well, easy to install and a reasonable price.”
Excellent filters and good customer service; will reorder.
“Excelent filters and good customer service.”
Warranty and returns come up often. Several reviewers say warranty claims were denied and returns were blocked by a strict no-exceptions policy. Fewer reviews describe quick replacement shipments and service that resolved the issue.
Billing issues hurt value for many buyers. Customers mention foreign transaction fees, duplicate charges, and surprise subscription charges. Some repeat buyers say prices are fair and the products offer good value.
Ordering and fulfillment vary widely. Some customers received their orders quickly with no problems. Others report canceled orders, prolonged attempts to place an order, or trouble reaching a representative.
Reviews describe uneven filter performance. Some customers report leaks, black residue, and bad taste or smell after installation. Others say installation was easy and the filters improved water taste.
Customers often point to poor follow-up. Reviewers describe refund requests that went unanswered, no phone access, and slow or missing responses to cancellations. A small number say the team was helpful when they did respond.
Ratings split between very negative and very positive experiences. Low ratings often focus on refunds, billing, and support problems. Positive reviews highlight product performance and fast delivery.
For each review, the core experience based on original source reviews.
