They don't remove TDS
What is TDS?
total dissolved solids. Only Reverse osmosis can reduce it, not carbon (Brita filter jugs)/ultra filtration.
Trump Derangement Syndrome
@EightImmortals: Is called epstein file, a very effective filtration between followers and their leader
More land fill
Keep in mind that RO requires a heap of energy. This thing sucks down 2200W
The 'actual reverse osmosis' step only needs a pump to raise the input pressure. Even the very high-flow 1000G RO membrane only needs a pump of 300-400W, and the flow rate of this machine is not even close to 1000 gallons per day.
It's the hot&cold thing that uses the power, it's just like a kettle whenever u need it.
Not much waste of energy here.
Is this actual RO? Could anyone advise me if this is anh good.
It's a reputable brand, and it states RO quite clearly, so no problem.
But the RO membrane it uses only lasts 2000L, I don't think this is a long life span.
Yeah also proprietary filters.
If you use carbon filtered water through it it should last way longer. Its chlorine that kills RO membranes
I just realized that this machine only has a post filter but no pre filters.
What kind of design is this…… Well even for the RO pump a pp pre filter is necessary otherwise the pump's lifespan will be significantly compromised.
Probably there is some pre filtration in the RO canister itself? But yeah definitely pour brita jug water in this machine.
@charmandad: There goes your "reputable brand" fairytale naivete out the window…
If chlorine is the problem, just leave the water in the sun by a window in the morning, and the chlorine will be gone by evening. Or boil it for 5 mins (and don't forget to let it cool before filtering).
@wisdomtooth: That was true decades ago, but today the primary disinfectant used in Brisbane, Melbourne and Sydney drinking water supplies is chloramine, not chlorine.
Chloramine does not evaporate from water like chlorine does.
@charmandad: That's because you shouldn't use RO on its own. RO should be used in conjunction with at least an outdoor 3 stage passive filter (up to the 7-stage filter under the tap). By the time it hits RO, you're more or less guaranteed to control the supply without compromising lifespan
Anh Good maybe, but Anh Do Approves
How does it compare to AquaTru, do you know? Isn't that the gold standard in countertop RO?
What is the specific brand of reverse osmosis (RO) membrane in the AquaTru? I would guess you'd struggle to find the brand, just good marketing.
My link above uses DuPont Filmtec reverse osmosis membrane …
https://www.dupont.com/brands/filmtec.html
DuPont
Yeah nah
@marshmall0w2: I checked quickly for you and it appears that AquaTru uses its own proprietary thin-film reverse osmosis membrane, rather than a third-party brand (such as Dow FilmTec or Vontron). This is confirmed by their official support article stating ..
“The reverse osmosis (RO) filter utilizes a proprietary thin-film membrane, engineered to provide superior filtration performance.”
Best of luck if you think that is better than DuPont.
@marshmall0w2: Coincidence that they created the PFOAs, and now are a market leader in RO membranes to remove the PFOAs! lol
I have the 5 stage version, best tasting water, i love my home water better than any, I was able to install it myself successfully, the remineralisation stage improves the taste.
Whi h one is it
I have this one and it has been great …

Hi @sn809
I have a similar one to Matt
https://psifilters.com.au/collections/reverse-osmosis-unders…
Matt's one is "Stage 5: Hi Alkalizer Re-Mineraliser – Adds essential minerals and increases pH for alkaline water."
my one "Stage 5: Re-Mineraliser & Alkaliser Cartridge – Adds calcium, magnesium, oxygen, and balances pH."
Reverse osmosis (RO) is effective at removing PFAS
Reverse osmosis (RO) systems are efficient at reducing high levels of microplastics
The activated carbon filter they (and the Philips unit) use is effective against chlorine, but the primary disinfectant used in Brisbane, Melbourne and Sydney drinking water supplies is chloramine.
More research is therefore needed before one buys to determine how effective activated carbon is with chloramine. The Philips unit does not even use carbon as a prefilter, so it does not appear to be well thought out.
the primary disinfectant used in Brisbane, Melbourne and Sydney drinking water supplies is chloramine.
ChatGPT begs to differ:
In Australia:
Most urban water suppliers still use free chlorine as the primary disinfectant.
Chloramine is used in certain networks — mainly where water travels long distances in warm climates or needs a more stable residual (e.g., parts of Sydney, Perth, Darwin, Canberra).
Regional/rural supplies almost always use free chlorine only.
That's interesting because I also used ChatGPT, but my question would have been worded differently.
Anyway, here’s another source: https://aquasafe.com.au/pages/what-is-chloramine#:~:text=Chl….
“Chloramine is now the primary disinfectant used in Brisbane, Melbourne and Sydney drinking water supplies.”
@bgazer: I checked my supplier's site, Yarra Valley Water, and saw that maybe my area is OK for now. My tap water though does not have a chlorine smell like it once had, so that advice may also be outdated.
It does indicate that many parts of the state have chloramine added to the water.
“Where is it used?
Chloramination is already used successfully in parts of the Yarra Valley Water system, which supplies water from Monbulk to Mount Dandenong Ridge and from Silvan to Seville East. Some of the other areas throughout Victoria currently using chloramination include Geelong, Wodonga, and Bendigo.”

It may not only be regional areas that are affected however:
https://www.facebook.com/groups/wavesaction/posts/3764838770…
"Beginning January 6, 2025, and continuing through January 27, 2025, Melbourne water customers may notice a chlorine odor in their tap water. During this period, the City of Melbourne will be temporarily changing its water disinfection method. This temporary change in water chemistry will not affect the safety of water for drinking.
Chloramine, which is formed from the combination of free chlorine and ammonia, is normally used for disinfection by the City of Melbourne. During the temporary change, free chlorine — without any ammonia — will be used.
“During this temporary period, customers may notice a chlorine taste or odor in their tap water,” explained Public Works and Utilities Director Jennifer Spagnoli. “These temporary conditions will not cause adverse health effects. The water will remain safe for drinking and other uses.”
Changing to free chlorine periodically provides additional protection against microorganism contamination and helps ensure the water you receive remains safe."
@bgazer: Meanwhile, in Qld…
In South East Queensland, chlorine is added to the water as part of the treatment process (Seqwater)
This sort of corroborates they only use chloramine in remote areas:
Ongoing progress on the Regional Secondary Disinfection Optimisation Project – targeted at improving disinfection residuals in Seqwater chloraminated water supply zones, as a key project from Water Quality service standards.(Seqwater Drinking Water Service Annual Report 2022-2023)
Thanks, I think I'll save the $599. You can get a lot of tap water for that.
If you are going to drink it in a quarter (supply fee is daily) $600 should get you about 1170L from Sydney Water.
Only out by a factor of 1,000. That would be 1170KL, not L.
some people tap water has stuff in it, which is why it needs to be filtered. not everyone lives in the same place
Enjoy your PFOA :)
After a quick google on these devices it’s a hard pass from me…
While this leads to very pure, clean-tasting water, it also means the water will have fewer minerals that contribute to taste and potentially health benefits like bone strength and muscle function. Some RO systems address this by including a remineralization stage to add these minerals back into the water.
There is some scientific concern that long-term consumption of demineralized water like RO water could cause mineral deficiencies and associated health issues if the diet does not compensate for these losses, although opinions and evidence vary.
TLDR: So the minerals restored in Philips RO water are introduced by the system’s alkaline mineralizer stage and are not simply retained from the incoming tap water, which is mostly stripped of minerals by the RO membrane.
The claim that it filters heavy and toxic metals is true. The claim that it removes essential minerals is also true.
But my way of thinking is different. The benefit of controlling what you'd be drinking almost 99% of the time is overwhelming compared to the loss of essential minerals. Why? Because you can always take essential and trace minerals from sources you actually trust.
This way, you get both benefits of eliminating toxic heavy metals and chemicals AND control the dosing of essential and trace minerals.
So your premises are correct but your conclusion is not on point.
A new sentence:
Controlling the dosing of essential and trace minerals.
Pmsl
There's no concern because drinking water is not a significant source of minerals, food is.
Sources or bs
I do doubt the nutrients present for dietary claim, but one i do prefer is
Fluorides, when i have many types of filtered and bottled waters i tend to get bad heart burn, acid reflux
Tap water and rain water i always know to be comfortable
The placebo effect is strong in this one Luke
Fairly expensive replacement parts, more so the RO filter. Requires two filters that last 2000L.
post-RO filter: $49.95 rrp
RO filter: $179 rrp
So $228.95 extra every 2000L.
Has anyone tried this compared with the tap system they do for $2K ? It looks kind of nice
Better to use industry standard high spec components in these pre-built kits .. cheaper to buy, cheaper to maintain, better quality, more flexibility ….
https://psifilters.com.au/collections/reverse-osmosis-unders…
Brilliant thanks
Got one, thanks OP.
Did anyone end up finding the newer model sold at a similar sale price anywhere apart from Myer?
I missed the boat it seems and the current RRP is a tad too rich for consideration..
