Customer Reviews
Ordered RO membrane, quick delivery
Got a replacement RO Membrane. Fast shipping, arrived in 3 days. It was the correct part. Installed it myself with no issues. Water quality is back to normal.
Good system, easy install
I bought the Reverse Osmosis Water Filtration System. Ordering was simple on the website, took about 5 days to reach me in California. Installation was surprisingly easy, even for me; the instructions were clear. Had a small question about a fitting, called support and they answered quickly. Water tastes much better now. Seems like a quality product.

Hey guys, thinking of getting one of their RO systems. how hard is the install really? I'm pretty handy but not like a plumber or anything.
Quick question, does Express Water ever do sales on their replacement filter bundles? Trying to plan out my purchase.
