Express Water
Start making better tasting food, ice, coffee, and drinks. You will notice a huge difference in the taste of your water and food. Make crystal clear ice without the impure clouds of unfiltered ice.
Extend the life of your water using appliances and keep impurities out of them. Deionization stops water impurities from building up overtime. With tap water you may need to replace appliances early or various living impurities can start growing inside them.
When creating habitats for aquatic life it’s important to start with the purest water possible. Whether you’re adding salts for reef tanks or specific trace minerals for freshwater fish, you need to be sure you’re creating the ideal environment, free of chlorine, iron, Total Dissolved Solids, lead and more.
Reduce up to 99.99% of over 158 impurities in tap water, including Total Dissolved Solids (TDS), Lead, Chlorine, Fluoride, Radium, Various Living Impurities, Arsenic, Cadmium, Pharmaceuticals, Chromium, Heavy Metals, Rust, Sand, Dirt, Dust, Cyanide, and more. Deionization creates some of the purest water possible.
Deionization dramatically increases reduction of the hardest to catch impurities through ion exchange. It attracts the cation and anions of impurities, leaving you with pure water.

DI Filter
"I bought these DI filters to tame TDS bleed through on a tankless reverse osmosis system. The TDS bleed through was as much as 35 and as low as 8 in fluctuation which is still very good RO water but wanted to see if adding a DI filter would stabilize the TDS and it did. The TDS fluctuation now is high of 6 and as low as 1 within a second of turning it on. I wanted to eliminate the bulky holding tank on a traditional RO but with the same or better TDS and this DI filter did what I was holping it would do."
It works great
"I used a tds tester and it showed right at 000! I used to have zero water but with this system I won't need it anymore."
15 ppm
"bought this to add to my ro system but I am still a reading of 15ppm in the water it's a big drop from 117ppm but not low enough for aquarium use"
As Expected

Q&A
- Where in the filter process should the ION filter be installed? I have the 3 pre filter, RO membrane, UV, and the PAC filter after the tank.
- Dear Valued Customer, Thank you for taking the time to contact Express Water. The ION filter should be installed after the RO membrane and before the UV filter in your filtration process. This placement ensures that the ION filter can effectively treat the water after it has been filtered by the RO membrane but before it undergoes UV disinfection. Please do not hesitate to contact our office directly at (800)992-8876, Monday-Friday, 8am-5pm (PST) should you have any further questions or concerns. We are here to help!
