Yes. We offer dedicated solutions for chlorine/chloramine in city water and iron, sediments, hardness, and tannins in well water.

Best RO/DI System Ever...
I installed the Dual 6 Stage Under Sink RO/DI system a few months ago, and it’s been performing extremely well. Water quality has been excellent. 0 TDS with no noticeable taste or odor, even with challenging source water. I have it connected under my kitchen sink using a small adapter, and it runs without any issues. Setup was straightforward if you’re comfortable with basic plumbing, and the compact, heavy-duty design doesn’t take up much space. The clear filter housings are also a nice bonus for quickly checking filter condition.

4 year review here and no leaks!!
If you want quality, portability and affordability, this RODI is for you. It is a MUST for reef aquariums. This will remove all that bad stuff you do not want in in your aquarium.

Works Perfect for all my plants.
This 3-stage hydroponics system feels solid and well thought out from the start. The filters are built to last, and the housing has that sturdy, no-nonsense feel you want in a grow setup. It doesn’t take up much space and tucks neatly under a bench or along a wall without getting in the way. Simple, reliable, and easy to live with, it does its job quietly in the background while keeping your water consistent for your plants.

LiquaGen Whole House Upflow Water Filter System
Installation was pretty straightforward for someone with basic plumbing know-how. I mounted mine in a way that makes it easy to remove if we ever move. We live in a city with heavily chlorinated water, and the improvement has been noticeable. Drinking and cooking water tastes much fresher, and we’ve also seen a difference around the house , fixtures stay cleaner, and even the dishwasher seems to work better. Overall, it’s made everyday water use a lot more enjoyable.

Truly Everything Water
This tankless RO/DI system has been a great addition to my home and was very easy to set up and it fit nicely under my kitchen sink. Everything has been working smoothly, and the overall experience has been excellent. I would definitely recommend this system to anyone looking for a reliable RO/DI setup.

Life Saver!
Our well water has very high manganese levels, which is common in this area because of the aquifer, and it’s always been a challenge. Since installing this unit, the difference has been night and day. The water is noticeably clear, white laundry comes out clean with no staining, and fixtures like toilets and sinks stay looking fresh.
What I appreciate most is that it does all this without needing added chemicals, unlike other systems I looked at. After a full year of use, I can honestly say it’s been a great investment and has performed exactly as hoped. Well worth it.

Does Exactly as Advertised
The difference this system has made is honestly impressive. Before installing it, hard water buildup was an ongoing problem, but now water spots are practically nonexistent. The water feels noticeably better to use, with a clean taste and no unpleasant odor. One of the biggest wins has been in the shower, hair feels softer and cleaner, and soaps lather much more easily, so we end up using less overall. It’s made everyday water use around the house a lot more enjoyable.

Best Upgrade For Our Small Office Space.
This RO unit is a workhorse. I set it up to a clean drinking water tank which I plumbed to a few places in my house with a jet pump. Works awesome. You won't find a cheaper more efficient unit, replacement filters are cheap compared to other units that can do this kind of volume. Glad to have purchased a unit with a company that backs their product.
