How will I know when it’s time to change filters?
You’ll notice reduced flow, a change in taste, higher TDS reading (for RO/DI), or a digital monitor/pressure drop indicator on certain systems.
Do your systems work for both city and well water?
Yes. We offer dedicated solutions for chlorine/chloramine in city water and iron, sediments, hardness, and tannins in well water.
Can I install the system myself?
Many homeowners install our whole-house, RO, and sediment systems themselves. For softeners and complex setups, we recommend a licensed plumber for best long-term performance.

LiquaGen- 5 Stage Reverse Osmosis & Deionization (RODI) ...
I don't often write reviews, but want to say that after I bought and returned units from other companies from various stores and online sites. This one has been by far the best! I've only had it a few days, but so far it has cycled out 100 Gal and 0 TDS and been really improving the quality of my saltwater tank! Not only that, the construction is solid, and high quality, and it came with the intake adapter from a hose connection (as it is connected in the garage and not under the sink, this is perfect!) PLUS, it came with a great float shutoff valve that I connected to the lid of my 5 gal bucket.
Robert K
LiquaGen Whole House Catalytic Carbon + Softener Combo
“For years our showers smelled like chlorine and left white stains everywhere. After installing the LiquaGen combo system, the water feels softer, glasses look clean, and even my wife’s hair feels better. Best investment for the home.”
Michelle Harper
LiquaGen 6-Stage RO Drinking System
“Our tap water tasted metallic because of old pipes. The RO system removed the odor completely. Now we drink more water at home than bottled water. The taste is honestly better than store brands.”
Michael Polliard
LiquaGen- Heavy Duty & High Capacity- 7 Stage Aquarium...
Finally made the decision to purchase a RO system for my saltwater setup. I have a 180g and 150g reef tank and this puppy does not disappoint. It supports all my needs with my weekly water changes. The setup process was easy, I probably made it more difficult on myself but I also add a water psi gauge and a TDS sensor. I am considering to add a pump to reduce the waste water, 3 gal of waste for every 1 gal RO adds up over time. Overall, great system, I would recommend this item to others.
Brandon Lee
LiquaGen Industrial RO/DI System (Car Wash Use)
“We use LiquaGen DI water for final rinse on cars. Zero spots, no mineral streaking, and it cut our drying time in half. Saved us money on towels and labor. High TDS city water was ruining our finish before.”
Annie Rodriguez
LiquaGen Whole House Sediment + Carbon System
“We’re in a desert area with heavy sediment. Before this, our faucets clogged every few months. After installing LiquaGen, no more buildup, no cloudy water, and appliances are running smoother.”
Dr. H. Andrews
LiquaGen 0-TDS Dual DI Resin System
“We require 0-TDS water for testing equipment. LiquaGen’s system maintained purity longer than previous brands, and the customer support guided us on resin life. Accurate results depend on this water. Exceptional.”
Jason P.
LiquaGen Water Softener + Brine Tank
“Our dishwasher and water heater were getting destroyed by hard water. The difference is immediate — no scale on dishes, shower glass cleans easily, and soap lathers better. I should’ve bought this years ago.”
