Customer Reviews
Great value, saved money
I was looking for an Under Sink RO System and compared a few brands. Liquagen had a good sale going on, which made it very competitive. I also signed up for their newsletter and got an extra 5% off, which was a nice bonus. The system arrived quickly and was packaged securely. Installation was a bit more involved than I thought, but the instructions helped. The water tastes much better now. For the price I paid, it feels like a really solid deal. Happy with the savings.
Whole house system experience
I recently purchased a Whole House Water Filtration System from Liquagen. The ordering process online was easy enough, and I received a confirmation email quickly. Shipping took about a week to my address in Texas, which was within their estimated timeframe. The system arrived on a pallet, well-protected. Installation was definitely a two-person job and took most of a Saturday, but the included diagrams were clear. I called customer support once with a question about bypassing the system for outdoor use, and they were helpful and knew their products. The water quality in the house has noticeably improved; no more chlorine smell. The pressure drop is minimal, which was a concern for me. So far, very satisfied with the investment.
Reliable as always
This was my third order from Liquagen, this time for a new set of Sediment Filters and Carbon Block Filters. Just like my previous purchases, everything was smooth. The filters always arrive on time, and they're exactly what I expect. I've bought their RO membranes before too, and they've held up well. It's why I keep coming back; I know what I'm getting. No surprises, which is what you want with water filtration parts. Consistency is key with this stuff.
Good filters, fast shipping
I ordered a Replacement Filter Kit for my RO/DI system. It shipped quick and arrived well-packaged. Filters fit perfectly. No issues at all. Will order again when needed.
Decent system, minor issue
I bought the 5-Stage RO/DI System for my reef tank. The water quality is great, my TDS meter reads zero. Setup was pretty straightforward, took about an hour. My only small gripe was a minor leak from one of the fittings initially; had to re-tighten it a couple of times to get it sealed properly. Shipping was about what I expected, arrived in 5 days to reach California. Overall, good value for the price, but double-check all connections.

Hey, anyone know if Liquagen does a military discount? My buddy told me some water filter places do.
Thinking of grabbing one of their whole house systems, but wondering about the shipping. I'm in Miami, how long does it usually take to get here?
