Great Filter

With the unwanted introduction of flouride in the town supply water I needed to go next level filtering and this filter does the job. I installed it myself and it wasnt hard. I drink a lot more water now knowing that it is clean. I rang the office for a chat and they were helpful with my questions. I Recommend this product.

Very happy with the unit and setup!

After doing the rounds online, we decided to buy this unit as it ticked a lot of boxes for us. 6 stages, good quality, good access to replacement filters, good price and good customer service from John and his team.

The unit arrived within days, and after studying the installation instructions for an hour and placing everything out on the floor, we decided to give the installation a go.

The unit came with everything we needed, except for the 12mm drill bit to fit the faucet and thread tape for all the fittings, so we had to go to Mitre10 to get these, and we also bought an extra stainless steel spring washer and flat washer as there seemed to be one piece missing in the faucet set. Not a major, just hard to figure out which piece it was missing as the graphic explaining the pieces wasn't super helpful.

Once we had these, we went at it, and everything came together pretty smoothly. We had a little trouble with the press fit pipe fittings, but that came down to our inexperience in using them, not a fault with the parts themselves. We also made the mistake of not tightening down the RO cartridge lid enough, so once it got pressure, it started to leak out. Again, our fault not the unit fault, it's just we had this problem because the pipe didn't line up with the press fit fitting if the cartridge lid was fully tight, so we had to remove the pipe and cut a slightly longer one and route it ourselves. Easy stuff.

Once these problems were solved, we let the unit run for 20 mins to clear out the system and boom, tasty fresh water.

Everyone in the house is super happy and noticed the difference straight away.

Here's to a future with ACTUAL clean water!

Thanks John for your help. I highly recommend this product.

Fantastic!

I only wish I had installed this years ago. With the upcoming mandated fluoridation of my families town water supply, it was the last straw. I had been humming about installing a drinking water filtration system for a while. I have no regrets, it was a simple install for myself with moderate plumbing skills and tools available. I installed it to both the on bench tap (that was provided) and through to the fridge water and ice dispenser as well, i had to purchase a T join ($10). I had very low flow at the fridge but this was resolved by buying a fridge filter bypass plug ($85).
The storage tank system is a must, and provides surprisingly good volume for about 5-6 litres before flow drops, which is plenty, as to not leave you filling a glass of water under a trickle.

We were going to do a blind taste test, but the difference was so blatantly obvious, after drinking the filtered water for a few days, just raising the glass of regular tap water to my face, and my wife did also, we could instantly smell the stench of chlorine. God knows, what other nasties we no longer drink. Unfortunately we still have to wash in it.

I did alot of research and I think this 6 stage Oasis system with the remineralastion, is the best and cost of filter replacements, and availability.
If I replace all the filters at 6 month intervals (max recommended life) and the membrane at 3 years (recommended is 2-4max). At current pricing it is a yearly cost of $512 per year. Not my cheapest bill but by far not my most expensive, nevertheless a bill i'm happy to pay to have spring quality water at the tap my young family to drink. A much better option than buying water in plastic bottles.

If you're on the fence, here's a simple question. A billionaire goes to a restaurant, the waiter asks. "Still, sparkling or tap water?" It's only ever option 1 or 2, and it always comes in a glass bottle.
Do you really think they would ever drink a city or town's 10 times recycled and chemically treated tap water? No, they would not.
