Works good, satisfied with the filters, wish were a bit cheaper.

Wish there was a link to the video instructions how to replace the filters.


Really don't want to admit this.....

Bought and installed September 2019......I have yet to change a filter.(it's summer 2022)...I'm on here buying replacement filters now. This is truly one amazing system. Every single person that drinks our water loves it. I'm really not exaggerating. Before the RO system I had 5 gallon water delivery and a tank....after spending 120 bucks a month on water I was done! I knew there had to be a better alternative and this was it. Wow what a life saver this has been. You probably should replace these filters when they say to however. This has saved me so much money. I bought mine off their eBay store but I see they have one on Amazon as well, all seem to be the same prices. If you're on the edge about getting one, I definitely recommend it. I'm a long time user and it works very very well.... It's one of those things you can install and forget trust me I did... Installation took me about 4 hours but I'm very meticulous it will take a normal person probably half that, it's not hard either just make sure you have room underneath your sink for the tank and the filters

Purchased this unit to replace the activated carbon filters we had before. The water this unit produces is superior in taste compared to the carbon type. We're very pleased.
