All of these RO system companies are just resellers. They buy membranes, housings, carbon blocks, and sediment filters and put them together and slap some stickers on them. The fancier ones have their own housings made. Just a few industrial type companies make RO membranes, Dow Filmtec are the best. The only thing worth paying for is a company that tests/guarantees >98% rejection on the membrane. Otherwise they are all the same with a few exceptions. Buy a cheap housing and put good cartridges in them.
I’m looking for an RO system due to the fact that my municipal water is very hard. I spoke with them and found out that they use chlorine and not chloramine, so that’s good news. Also the hardness is about 250ppm according to them give or take. The ph is really high out of the tap as well I’ve had readings between 9.5-8.0 I was looking at this one on Amazon; it’s a Hydro Logic 150gpd unit. I just get thrown off after reading reviews and there’s so many to choose from so I’m even more confused than when I started. Thanks
