### ⭐⭐⭐⭐⭐ Easy to install, because it was the correct part.
*by S***E on January 24, 2026*

correct part. It's a water filter, and it filters water. What more can you ask?

### ⭐⭐⭐⭐⭐ great replacement
*by J***Y on September 2, 2025*

Works great in my APEC RO-90, thank you

### ⭐⭐⭐⭐⭐ USA made, reasonable price -> only way I’m gonna roll with my drinking water!
*by D***N on January 5, 2026*

USA made, reasonable price -Skip the alternatives which likely dont have legit certifications or testing. FYI - product delivered in a sealed dry bag, other brands are vacuum sealed. Checked with mfgr and this is normal…..so no need for concern if you are used to a vacuum sealed bag with other brands. They also have their own filters worth checking out….some USA, some import.
