I live in a hard water area. Until now, I’ve been using a standard water filter like Brita, which has worked fine, but I could never achieve the clarity I was looking for in my coffee.
So last week, I dipped my toe in the world of water recipes. I got myself a zero water filter, read up about remineralisation and made a few litres of coffee brewing water.
I wasn’t sure what to expect or if it would make a difference, but man was I surprised! The difference is insane. It was the missing piece to tasty coffee that I had been searching for for so long. Needless to say, I’m sold now and theres no going back for me.
What concerns me us how much of a pain in the ass it is. I have to have a bottle for the mineral water concentrate, a filter jug for the distillation and another jug for the remineralised water. I don’t know if I want all that hassle every day for the rest of my life.
So the question now is how can I streamline this?
I live in a rented city apartment, so space is limited and I can’t make any big changes like under-sink ro installations. I have looked at countertop ro units, but they’re very pricey
Is there anyone else here who makes their own water? How do you manage this? Any advice for someone who is just starting out?


fwiw I’ve had this one for like 3 years now, no complaints. think it’s slightly cheaper on ex amazon tho https://aquatru.com/products/carafe-countertop
What a yucky/scammy/click baitty website vibe, what’s with the “click here to reveal your secret discount” and the forced subscriptions &auto billing on filters?
yeah it’s kinda awful, but I like linking directly to amazon even less lol
It also just appears that you can’t change the RO membrane? Can’t tell because it’s purposely vague, but looks like if you don’t get the subcription you don’t get any filter to start with and have to pay an additional $90?
Edit: its is RO but I don’t see the RO membrane as one of the replaceable filters.
Edit 2: found the RO membrane, it’s $60 every 2 years so yearly cost will be $120 ($90 for filter + $60/2 for RO Membrane)
the amazon one came with one of each filter. not sure about directly from them but I imagine it’s the same?
That’s actually the unit I’ve been looking it. It’s pretty expensive, so I’m glad to hear you are getting good use out of it.
Would you recommend it? Is there anything about it you would change?
nothing major.
we have pretty hard water here, it was killing one of the generic charcoal pitcher filters within a month. the filters in this one haven’t had any problems by the time they are scheduled to be replaced.
a couple possibly annoying things:
