Was on the lookout for a Reverse Osmosis (RO) water filter today. Was going to buy from Qantas marketplace (Philips AD6921 was discounted 20%) but noticed this evening that JB Hi-Fi have taken 20% off all their Philips RO units.
The AD6921 (hot and cold water output) is also reduced 20% down to $1039.20
I had Good Guys beat the price by a few dollars and they added their 3 year Gold Service Extras for what it's worth.
I drink water at room temperature most of the time so didn't see the need to spend the extra $$ for cold water function. This unit comes with two jugs so we'll just store one in the fridge.
Same here. Have it and very happy with it. Might not be the cheapest solution but it's a great option if you're renting or dont want to mess with sink plumbing. Instant hot water is nice too.
One jug doesn't poor quite right and the water spills a bit, has anyone else had that? Any solutions?
Now that you've mentioned it, yes! I tend to pour it over the sink now because it drips when pouring too fast.
Just wondering where those waste water gone?
I think the 6920 is the old model,.right?
Not sure. It's still being sold by Amazon, JB Hi-Fi & Good Guys. When I was researching I came across this other model AD6912 which seemed like it was a newer variant. To me the cons were slightly smaller tank, 2 filters required and less options for adjusting water temp.
Not sure may be this is just hot no cold
Newbie to this stuff, how long does the Reverse Osmosis process take? In other words, if I'm out of water and refill the tank, how long until I can get more filtered and RO'd water out of it?
The specification on the Philips website says water flow = 0.2 L per minute
There are 2 filtered water tanks/jugs. We use both and are rarely caught out with no filtered water.
does this do sparkling too? does it have a sensor to detect how much water to put in cup?
No sparkling water and no sensor, you select the volume of water output you want (e.g. 150 mL, 300 mL, 500 mL etc)
What’s the point then if it’s not smart.
My 7 year old xiaomi one does it
How much are the filters?
Seem to be around $220 from local suppliers but cheapest I found was $140 shipped from Amazon Germany. The filter is expected to last for a year though
Filter is rated for 2000L. Very conservative to last a year for a family. Especially if using it for cooking as well as drinking.
I have this unit more than one year. Use Brita filter as pre-filter water can extend the RO filter life time. The good guys commercial online sell it for $179 + delivery.
This seems crazy expensive. How much bottled water could you buy instead?
But bottled water doesn't have a show off factor nor $200+ cartridges per year.
Bottled water also has the, you know… bottles.
At $0.50 per litre (which is the best I've seen in a while) it would cost $1000 for one cartridge worth of water.
Or looking at it another way for $800 you could either get 1600 litres of bottled water or your first 2000 litres of RO water (ignoring electricity cost). Your second 2000 litres of RO water is even cheaper, $220, which would only get you 440 litres bottled water.
This unit is cheaper than buying bottled by far.
While this may be true it depends on your use case and how far you are willing to push the refills.
For example I calculated I used $160 on bottled water last year. Which got me roughly 250L of water. I would have to push that filter bottle to at LEAST 2-3 years to try to max out that 2000L capacity but they said to replace it after 1. What do you do? Ignore these instructions and use it for 2-4 years? Or replace it ?
In your case of ultra light usage I would not even bother because it would take 5 years for intial payback and 8 years to use up the capacity of the first filter cartridge, and I would want to enquire about how long (rather than how many litres) the cartridge can safely last once you've started using it. Or…. you could pre-filter 8 years of water in advance before the cartridge's recommended life expires. Or maybe increase your usage of filtered/bottled water (use it for cooking as well as for all your drinking water needs, drink more water and less flavoured and bottled drinks 680mL of water per day seems low).
@tenpercent: Yer i'll be real my water intake per day is a little low. I am drinking outside of the house but it's nowhere near the recommended intake.
Thanks for the ideas. If i see another sale I may bite, it'll be a good excuse to drink less flavored stuff like you said.
I also have the hot and cold version. Not worth the extra for the cold feature as you have to wait 15mins for the system to convert to cold (150ml). It comes with 2 jugs so we jus store 1 in the fridge anyways.
You're meant to leave the cold feature on during summer or if cold water is dispensed regularly.
If you really want RO water this is a very expensive way to get it. It may not be pretty but I have an RO unit that I use for my aquarium that has been going strong for several years without needing to replace the filter and still puts out water <5ppm down from >200. I think I got mine for <$100 several years ago.
Check out the water filter factory on eBay for where I got mine. Replacement filters are cheap too compared to the OP product.
That said I do see that this is more convenient but at what cost…
what brand?
I use the purereef ro 5 stage system. Aussie company and made here too. Its around $500. Connect direct to a tap.
$500 per cartridge?
@tenpercent: The whole system. the 5 filtration "canisters" with the filters. Customer service is really good there and they will tell you what level of filtration is adequate. You can also upgrade the system to an extra stage/s. I upgraded from 3 to 5 and could just add the extra 2 filters into the system.

@Sammyboy: So I actually have a very similar system bought for my reef tank, but I understand that it's not the best to use for drinking water due to the minerals being completely stripped out. This Phillips has a remineraliser to out those back in after the filtration, I wonder if we can get something to perform that for our RODI water so it can be used for drinking…
@CrazySurfaNZ: Keep some argonite in the water jug lol Or you could probably just throw some murray river salt into it. Remineralisers may be a bit gimmicky too. Some sites seem to say if your diet is pretty balanced you shouldnt need to remineralise the water…
Damn Myer had it on clearance for $690 at one stage =(
That was the older version :) lower tank capacity (4L?) and didnt store filtered water in the removable jug.
I’m still unsure of why this at home? Can’t you use a on-bench water filter from Bunnings, isn’t RO for salt water? What about the alkaline left in water after RO?
These RO systems are meant to be effective at filtering PFAS, microplastics, etc. Our current standards for drinking water allow a much higher level of PFAS than other countries which concerns me. Just trying reduce further exposure if I can :) (everyone already has some level of PFAS accumulation, it’s impossible to avoid).
Ahhh makes sense now, thanks
We have the hot & cold version. Works great, down side is topping up frequently if you have a large family. Beats having to change Brita filters every month.
