I'm looking for recommendations for a good ro/di unit

Marktheshark83 · Apr 2, 2016

I'm ready to buy a ro/di unit for my house, sick of goin to lfs to buy it. What's a good brand to go with?

I don't need one with high water volume, only really need 10 gallons a week. 5 for water changes and about 5 for top offs.

Do they even make one for small tanks/volume output?

Thank you. Links would be helpful; )

Spectrapure. No other vendor treats and tests their RO membranes or blends their own DI resins.

I've been using a PurelyH2O unit for 5 years now and I love it. Before that I had the Spectrapure and another before that, which I do not remember. I don't consider the filters when buying a unit. Any filter can be put into any unit, so you can switch those out anytime. You can have Spectrapure today, BRS next month and someone else the month after that. I love the outfit I currently have at 300gpd. Get the biggest membrane you can afford. It's not about how much you can make in a day, but how fast you can make it when you need it. If I have an emergency, or need water for "whatever", I can make 12.5 gallons in an hour. If someone had a 75gpd outfit, for example, they could make only 3.

im a spectrapure supporter, but i will agree, but the largest you can afford. Sure itll cost more, and replacing the membranes will be a bit pricey...but as @Lionfish Lair said, its great to be able to make a decent amount of water in a short period of time. I have a 180 GPD and wouldnt think of going down to 75 or 90...being able to make enough water for a WC in a few hours is great(7.5G/hr).
