I live in an area whose water supply is around 200-300ppm TDS. I'm not letting that come anywhere near my E61 machine, so I use the "Zero Water" filters and then remineralize. This is convenient, but the filters don't last long, given the water they have to work with. How do you treat your water? Do you use RO? Is there a less wasteful/expensive method of water purification I don't know about? Thanks in advance for all your advice.

I’m around 130 TDS and I’m still on my first filter since January - yesterday it was still giving me zero

@"Uncletits"#p70651 Thanks for that. I get through one filter a month. Once I've remineralised, I'm at around 120ppm. If I had water as relatively pure as yours, I might not even filter. 😉

@"PianoMan"#p70653 - my water reads 180ppm - 200ppm TDS. However, the hardness in terms of calcium carbonate is 310ppm. I use ZeroWater. One filter lasts me around 6 months. On average, I use 1.5L water a week.

@"MediumRoastSteam"#p70655 I'm starting to think I'm a heavy coffee drinker. 🤣 I get through around 10L a week. Perhaps it's because I have to flush the group head when I make a coffee. It's not the most water-efficient process. ☹️

Live in Kent crazy hard water - have a full house softener - which then goes into the zero. Usually get around 65-100 tpm - had the first set of filters in since april 24 - maint light just come on so it must have hit 2000 litres. Though tbh the readings seem fine still.

@"MattH"#p70659 A softener removes the calcium hardness, yes, not just a purifier? Forgive my ignorance as I'm fairly new to this. I share your frustration with water hardness. I honestly don't think I could run an e61 style machine straight from the mains.

I make rodi water they cost about 80-100 to buy and install.

@"Cuprajake"#p70661 Is that a standard RO system? Do you perhaps have a link?

I use this system. https://www.waterdropfilter.co.uk/collections/portable-reverse-osmosis/products/instant-hot-water-reverse-osmosis-system-wd-k19-h The price varies almost daily. I paid £279. It is quite quick, has worked faultlessly in the 2 months I have had it. They are a global company. I used to use the Osmio Zero system which is nearly £200 more. I do have to add bicarb back in to the water for use if my coffee machine but for me the pro's outweigh the con's I have just checked Amazon and it is currently £269 https://www.amazon.co.uk/Waterdrop-Instant-Dispensers-Countertop-WD-K19-H/dp/B0BRMWKJ19/ref=sr_1_1_sspa?crid=38ZT436W2WYCE&dib=eyJ2IjoiMSJ9.xkFNOU04MGbmwbEkqArwvPxM0ZgPRDd_EjIvyeavtS1sPKbhK2JXcWMbgOaoykchr_gCJCnx6D0bTKKp5PSjvcbYC_wxG4LpwLN-_AbFUDvwRwVxoTO2OSnHVjClQTjiH8D3UjftYrn74Z7GAi9UJMBcgBOC5jTxcg96_rnwPBSv7w3D6u2q7slbPltsDzg7_rWnUlffy4D02ATnRktAb_cyxJu1ZBlo2kc0WrntmZ0H5tJ3fP4D45rcuLOL37nR9AIZJeCeBcWx3G9tShu06m4G4J1t5OBrSNZE3uxCZyU.oEoPg7c9nWYXIdrOuFUw9DbKJpnmI4Y28kAxH4p8FMU&dib_tag=se&keywords=waterdrop+k19&qid=1723984248&sprefix=waterdrop+k19%2Caps%2C112&sr=8-1-spons&ufe=app_do%3Aamzn1.fos.d7e5a2de-8759-4da3-993c-d11b6e3d217f&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1

@"PianoMan"#p70660 Yes just the hardness (or at least reduces it) and then the Zero has to work less hard so it keeps the filters lasting longer.

From what source to people get the purified water (i.e. with near-zero TDS)?

PianoMan

Cuprajake I’m in Lincoln. I’m pretty sure the water in my taps comes directly from a public toilet. 😡

so ro is pushed through a membrane and will leave some tds in the water, the final stage is the di which turns it into pure water the same as distilling,

its neat/pure

my setup has a meter that shows the input/output of my sytem around 65-70 in and 0 out

PianoMan

Cuprajake The question is, how does a traditional, installed RO machine compare to a countertop RO machine (which I’ve only just heard about) in terms of purity.

PianoMan The question is, how does a traditional, installed RO machine compare to a countertop RO machine (which I’ve only just heard about) in terms of purity.

The purity for both is fine if it’s for coffee/coffee machines. Countertop - no plumbing, no leak concerns, no drain routing and produces hot water. Installed, requires drain routing, and if the installation leaks, a lot of water everywhere and doesn’t usually produce hot water (but some can)..

The main difference is filling with water vs not filling, for me filling a 5 litre tank once or twice per day is no biggie.

PianoMan

DavecUK Which one did you get?

DavecUK

PianoMan I have the Ozmio 0 which has served me well for 6 years plus but today a Waterdrop arrived. I purchased It from Amazon and I thought I’d give it a try. It’s a bit too early to say yet, how well the water drop works and how convenient it is.

The Waterdrop K19 price was very attractive from amazon.At £269 delivered

PianoMan

DavecUK Fun times. It’s always good to get new gear. I’m increasingly thinking the countertop RO is the way to go. Thanks

When countertop wasn’t available, I had undercounter, but kept a weather eye out for countertop. When it became available, that has always been the recommended way AFAIC

PianoMan

DavecUK I looked and it’s back up to 299, otherwise I’d probably grab one now

269…..

258 warehouse deal as new

DavecUK

I checked 1 hour ago is was still £269, here at this link.

https://tinyurl.com/2d2wvaqz

PianoMan

DavecUK still 299 for me. There’s a used one at 269, but that’s not for me. I guess that’s the internet, for you 🤪

Adrianmsmith

PianoMan

Used one is 258…. Try my link above as well.

PianoMan

Nope. What a rip! I guess that’s the internet saying look at other options. I’d pay more if I got more. Any suggestions?

PianoMan

PianoMan ah… I just read. It’s a prime exclusive.

PianoMan - you could always get prime OR… just suck it up. In the grand scheme of things… What’s £30 these days, specially on something like that over 5 years?

For that price, however, you can buy a ZeroWater jug and enough filters to last you the next 8 years, assuming you use 3 filters a year.

https://www.robertdyas.co.uk/zerowater-3-pack-filter?_br_psugg_q=zerowater+filter - 3 filters, £32
https://www.robertdyas.co.uk/7cup-17l-ready-pour-water-filter-pitcher - Jug (includes a filter) - £23

MediumRoastSteam

Adrianmsmith - It’s a Prime deal. Do the same in incognito (or log out). And the price will be £299.

Adrianmsmith

MediumRoastSteam

Ah, ok. Sorry 😎

Do you live close to dave or me 😎

PianoMan

Adrianmsmith Lincoln, but probably not. Either way, now it’s no longer discounted, there are other options. People seem to be raving about the Aquatru, for example. It has a more RO-style filter and I’m not paying for a hot water dispenser.🤔

dfk41

PianoMan People seem to be raving about the Aquatru

Just a quick glance but I find the blurb very confusing. It seems that the Classic is £349 and the 3 filters cost £100….I might be wrong button t it seems that not having a hot water facility costs a bit more?
