### ⭐⭐⭐⭐⭐ Great Replacement for Acquasana Shower Filter
*by Z***N on March 10, 2026*

Easy to install, fits and works good on my Acquasana shower filter system. It is also cheaper than the Acquasana replacement filters.

### ⭐⭐⭐⭐⭐ Nice product
*by J***. on May 18, 2026*

Work. Not as long as I would like. But does remove chorline

### ⭐⭐⭐⭐ Won't order anymore, water pressure killer
*by J***D on January 4, 2026*

UPDATE: The seller saw my original two star review and reached out with incredible customer service to resolve my issue desribed below. I gave the last filters I purchased two stars in my original review, but have amended my review to 4 stars because of the great customer service. I've ordered these a number of times. Sometimes they're decent and sometimes not; more recently not. Water pressure goes to a trickle within a couple of weeks of installation of new filter. Very aggravating. Can't justify continued use of them.
