    Question Water filtration - Brita vs 3M? Something else?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Once a year I have an urge to get proper water filtration system.
    I want to be able to manually fill the water tank of the espresso machine with stainless steel boiler as well as I want to use filtered water for drinking/cooking.
    The plan is to get 3-way tap to avoid drilling the sink.

    But the main question is what brand/system to get.

    There is not many options available in Australia.
    I see a lot of people are using Brita Finest (C150)
    Some people are using 3M (HF15-MS)

    I am here to listen to people's opinions on these brands (and other brands).

    1. Have your water professionally tested
    2. You have stainless boiler/s. Get a buffering filter.

    1. No, the water wasn't tested. I am in Sydney so water supposed to be not too bad...

    2. What is buffering filter? Sachets to drop into the tank?

    Send some water to Bombora, they will recommend a filter based on your water and usage

    Do the sell to public?
    I have never seen prices on their website so I assume they are wholesale supplier only.

    1. So you don't have any information about your specific circumstances- only broad generalisations.

    Time for you to do some research on the effects of conventional softeners and pH. Acid and chlorine/chloramines are stainless steel boiler nemesis.

    Until I send water samples for testing the best I can do is Sydney Water Quality Report for my region.
    https://www.sydneywater.com.au/web/g.../dd_210921.pdf


    My question is more generic too - I saw some comments where someone was saying switching from 3M to Brita affected the taste that much so that person switched back to 3M.
    Obviously Brita Finest C150 looks like the most popular domestic solution for machine with stainless steel boilers.
    But I was wandering if water going to taste Ok for general use after this filter.

    Espresso machine is going to be Ok as long as numbers are right.
    Yes, I need some more research about people. (how filtering affects water taste)

    Yeah, that was me...

    The issue is though, even though the Brita C150 Finest was the recommended filter for us to use after water testing by Bombora, the overriding concern was more focussed on Total Hardness issues than anything else. My lovely lady identified the issue first as she loved the water being supplied through the 3M unit but could not bring herself to drink the water from the Brita after installation - To her, it tasted metallic.

    I didn't think it affected the taste unduly of espresso from our Dual Boiler machine so was happy to continue. However, when it came time to replace the filter the last time, and then involving my wife in the decision, she definitely wanted to go back to the previous 3M filter so, that's what we did.

    As it turned out, it was totally worth doing as the quality of coffee in the cup immediately improved to the point where I decided, for us, the drinkability of the water was so improved, we both swore off competing filter units from that day forward.

    All of the above relates to our circumstances and the chemical makeup of the town water we are supplied and may not be directly replicated for your own particular situation. We are however, happy that we made the switch back to the 3M filters.

    As I recall, Dimal is also using a Flair now rather than a dual boiler e-61 machine.

    In addiction, his previous dual boiler Diadema would have been copper rather than stainless steel boilers.

    Al in all, a whole different ballgame and the 3M is certainly fine given his new (specific) circumstances.

    Was pretty darn fine with our original HX Junior Extra too, but that's going back a fair while now.
    In defence of the Brita filter system, the DB JE didn't have a single solitary nodule of scale to be found anywhere. They definitely live up to the claims made by Brita...

    This is exactly my concern - I don't want filter for expresso machine only, I want to drink raw water too.

    As far as I remember it was 3M HF15-MS. Can't find if it suitable for stainless steel boiler.
    Going to talk to Bombora tomorrow.

    No mate, for s/s boilers the Brita C150 Finest is the best (and only) single cartridge filter system that will look after the boiler for you.
    Not worth the risk to try anything else unless the Bombora guys and gals recommend an alternative we don't know about yet...

    I see I see.
    I was under impression 3M is doing the same job.
    Metallic taste - here we come...

    Thank you for the input.

    Haha....

    Don't stress about what my very clever wife can detect in the water, she is some kind of supertaster and I defer to her when ever the issue of taste defects arise...
    You may not even notice anything at all, I didn't until she pointed it out to me.

    Agreed. The C150 Finest water certainly does taste somewhat flat and inert to me. I have never got metallic though.

    Ion exchange normally tastes great in that (for me at least) low concentrations of salt taste very slightly sweet and somewhat sparkling.

    Haha, understood.

    Just called Bombora and asked if 3M HF15-MS is suitable to stainless steel boiler espresso machines.
    And they didn't tell me without testing my water.
    I though it's a general knowledge.

    So I called 3M.
    They can't tell me straight away either - they promised me to call back when they figure it out.

    Nope- they won't without a test- but I (and others) have already mentioned that...

    Unless your tap water meets https://techcenter.lamarzocco.com/js...calculator.jsp you can pretty much eliminate ion exchange with SS boilers.

    Save your time asking the same questions here and elsewhere. Have your water tested.

    Don't know how much clearer we can be, to make the point to be honest...

    No, I couldn't pick metallic either but like you mate, I could pick a difference.
