## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect !
*by M***V on April 16, 2025*

Great ! Exactly what I needed .it Works

### ⭐⭐⭐⭐⭐ Works really well, but my whole house water filtration system is lackluster
*by D***E on July 24, 2024*

There were no items in the package that were missing or damaged. Works really well, but my whole house water filtration system is lackluster. You'll want something like this if you're off grid, or living on an island in the middle of the ocean, lol.

### ⭐⭐ Only lasted 3 months
*by F***S on March 25, 2025*

Purchased in December, installed January 1st. Fully Clogged by 23 March (3 months later (9,000 gallons)). I have multiple pre-filters, and the membranes I had before this one lasted much longer (1 year, 36,000 gallons). Now I am buying new membranes again, but a different brand than this. As they say, you get what you pay for.
