Pure Water water filters

[TC]

Sam,

The overwhelming body of what you have written has little relevance to coffee filtration.

....but I certainly know we were drilled for a full week of training about the difference between carbon block and reverse osmosis filtration - namely, the inability of carbon to remove TDS from the water supply.

That took a whole week?

Sorry buddy, but I place zero trust in those who knock on doors and then pitch "the script". I'll pass and I'll continue to use the products tested and recommended by a sponsor of high integrity.

Try next door mate. They might be more gullible.

Hi, my name's Sam and I work for Pure Water Systems, I never normally do this when I see threads with misleading information, but I felt compelled to sign up just to reply and set some things straight.

As a direct sales agent I am responsible for knocking on the doors of the public to convince them of the idea of drinking purified water. I agree that the water purification industry is comparable to the snake oil business, there is a lot of jargon and mythical information floating around in order to suck people in to buying inferior products at a cheaper price. I just have to say though, when it comes to people trying to do the right thing in this industry, in actual fact we are not talking about "shonky pseudo-science" but real chemicals and pollutants in our water supplies that we all ought to be aware of. I can't speak for the rest of the sales agents out there working for pws, but I certainly know we were drilled for a full week of training about the difference between carbon block and reverse osmosis filtration - namely, the inability of carbon to remove TDS from the water supply.

Not once is it advertised or are we taught to push carbon filtration as reverse osmosis or vice versa, and I completely agree with you when you say that is a dodgy tactic! I, for one, would never recommend a countertop filter to a coffee shop (for a number of reasons)! Having said that, reverse osmosis is a very time consuming process, so if any of you have what's claimed to be a reverse osmosis system hooked up to your machine without a pressure holding tank you should start looking for the real deal

In regards to the counter top system that bombora is offering for a much cheaper price, it only filters at a nominal level (meaning it can work between 6% and 95% efficiency at any given time), and only filters down to 0.5 of a micron - anyone who knows what they're talking about will know that ecoli can squeeze down to 0.4 of a micron, not to mention the other things getting through with that 0.1 of a micron difference. The cartridges that we use filter down to 0.4 of a micron at an absolute level, meaning they have 96%+ efficiency at all times, they are made from compressed carbon, contain a statically charged vegetable cellulose outer wrapping and a central membrane (so a 3 process filtration).

The other thing you have to watch out for when purchasing a filtration system on the cheap is cheap plastics and chrome that can leech back into your water, and that's not even mentioning lack of warranties and after sale support

Please, I would like to set these things straight and welcome any more questions or differing opinions!

Cheers,
Sam.

I got visited by a snake oil salesman a week ago and he told me about the wonders of his product too Seriously the domestic water filtration industry is full of shonks and pseudo science that would make a used car salesman blush!

Correct filtration for the given situation ALWAYS.

Hi Beanflying

I'm with you on this. I too have an RO 4 stage system which gives me around 35- 38 TDS. I was worried that it might be a bit low for my Giotto Premium Plus due to the sensors not registering water. But after talking to Chris at Talk Coffee, he said that should be fine. I never get scale in any of my machines. I also have my whole house filtered by 2 x 24" cartridges. 10 micron polyspun sediment and 20 micron carbon block. Cant beat good quality water.

research Town Water Supply and see how your municipality treats their water. You will be shocked.

Research it properly and you'll find that potable water in Australia is of extremely high quality in terms of general consumption (ie, drinking, washing, ...). If you want to produce quality espresso, then you have some tighter tolerances to deal with. Test a few rainwater systems and poorly maintained filters systems and you will be shocked!

I also had a water consultant from pure water at my door last week

Let him in as I was curious as to what he thought

Told me that the bench top filter I was using from Bambora was no good

Told me my filter was Nominal and being 5 micron pretty much useless

I needed one of his 0.4 micron absolute filters then filters for my showers and so on .............

Spent a hour telling me how bad our water really is, did a couple of tests using chlorine and a tomato and then they always get offended when you don't purchase anything from them, like I've wasted his time

I'm happy with my Bambora bench top.

[QUOTE=chrislng;471184]Hi all,

Was contacted by the Pure Water company a mob in Queensland I believe.

And on answering a survey I have won a free bench top filter system. The catch I need to buy one of there filters.

The filter is $100 and rated for one year, Im due for a new filter soon so I may just take it but I wanted to see if anyone had any insight into it.


The filter is as follows:

CC1E-HT 0.4 Micron

Commercial non-sponsor link removed

What you think? [I was contacted by the same people about two years ago asking me if I would like to answer a survey, and for doing that they told me that I had won a bench top filter system when I agreed I was told I needed to buy a filter and would cost me $124.90 plus postage and handling $7.50 a total of $132.40.The filter model is CC1E-HT 0.4 micron. I have also checked on line with another company today and for the same model number It will cost me $52 but I think there may be postage charge on top of that.

Re: Pure Water water filters

Carbon is great for pulling solvent out of aqueous streams 8-). The only way to pull out calcium & magnesium is to use a softener which acts on an ion exchange principal.

I treat filtration as an investment to ensure my unit stays in tip top shape - do not cut corners when it comes to water quality.

[beanflying]

Re: Pure Water water filters

As already stated Carbon will not remove calcium. Water Softeners if needed are very different.

[arcenite]

Re: Pure Water water filters

Make sure that the filter specifically removes calcium. If Im not wrong theres a special term for it, just forgot what it was and yeah contact bombora.

[beanflying]

Re: Pure Water water filters

I noticed it filtered to 4 microns and used reverse osmosis unlike my current filter.

Thats the sort of snake oil they use. A carbon block filter HAS NOTHING to do with R/O which is an entirely different process. That is false and misleading conduct and if you pushed the point against trade practices etc!

Re: Pure Water water filters

Yes! You have won free flights to Paris! All you need to do is stay in one of these beautiful remote 2 star fleaholes establishments at 400 Euro a night for 2 weeks :

Lots of well-meaning plumbers/filter sellers do drinking water and have little idea about scale nor espresso machinery.

Best leave it to the pros. Speak with Bombora

Re: Pure Water water filters

I currently use a bench top from Bombora with a CFS117O Cuno/3M.

It was just that the lady was claiming this thing was the best thing since sliced bread and I noticed it filtered to 4 microns and used reverse osmosis unlike my current filter.

I am happy with my current setup so I think I would give it a miss.

Re: Pure Water water filters

Water for Espresso or Brewed coffee is different to nice tasting water to drink. Keeping scale in check is as much important as anything. The filter you have been offered wont do that.

The domestic water filtration industry is worse than buying used cars. Blatant lies and pseudo science abound along with overpriced under performing products to boot. Think Snake oil of medicine man shows and your getting close. The couple of sponsors here do however know their stuff.

The things you need to sort out are does the water taste ok already? If so then maybe a pre filter followed by a carbon filter then topped off with a softener cartridge if required. But water supplies vary dramatically across Australia.

Currently I am running a pumped Reverse Osmosis plant with prefiltration which gets me to around 40PPM TDS which is great for Espresso (could be a touch higher) but it tastes flat if I am making brewed so I have a remineralization cartridge I am playing with to make a shandy of sorts and get back up to 150-200PPM. Our local supply runs from 500-900PPM TDS (Tastes like ) and kills plumbing.

So to clean can be bad and the wrong sort of clean can still see you with a blocked up machine.

Let us know where you are or what sort of water you are running?
