Good day, folks, right from our water filter here, today. And what we want to do, is have a look at some reverse osmosis systems, and just compare a little, and just give you an idea of how they work, so when you're gonna purchase one, you've got a bit of a guide on what you should be looking for, OK? So, what we've done here today, is throw up probably the four most popular reverse-osmosis systems that we sell, OK? So, in the benchtop range, little RO4000, and the RO4000 with alkalizer, I'm gonna talk about those in a second.
Then we've got the big, under sink, Aquasana system, and the Xtreme 7, OK? Now, the situation with these types of water filters, reverse osmosis systems, and I often tell customers this on the phone, is, I don't care where it comes from, it doesn't matter what sticker it's got on it, it doesn't matter what shape it is, all of these filters you see here, are producing similar water out the other side, OK? But, what is important with an RO is what it does to the water, after the membrane, OK? So just remember that. It's the important part of an RO system is what it does to the water after the membrane. Now, to give you an example, this here is a good old-fashioned, twin water filter.
Forget about what's on the top, and basically how it works, the water comes in this side, and in this cartridge here is a sediment cartridge. And that sediment cartridge takes out the lumps and bumps out of the water. Then the water comes over to this one. This is a carbon cartridge. Takes out the chlorine chemical. And they're there to clean the water up, before it comes into the membrane. So, stage one, stage two, stage three is the membrane. Inside this RO system, the same.
These in here, are these type of cartridges, which are known as an inline cartridge, similar to this. So, inside this box, and inside this box, are these long cartridges, with a membrane like that. Once again, the water comes in, it goes through a sediment, it goes through a carbon, and it goes through the membrane, inside here, same here. Now, when that happens, the water goes through the membrane and the RO membrane splits the water. Down the drain is going all the contamination, which is what we want, no problem. And then, on the other pipe that comes out of the membrane, that'll connect into a tank, or if you're using a benchtop model like these two, the blue pipe is the pure water, and you fill up your own containers. Obviously, RO systems work very slow, 200 mils a minute, that type of thing, OK? But they create very pure water.
Now, what's gonna happen, sediment, carbon, membrane, and we've got the water, OK? The water has been stripped of all of the contaminant, but, because these membranes strip the water so fine, it's also stripped all the mineral out of the water, all right? Now, the water's very fine, it has a very low TDS rating, when the water comes out of this membrane, OK? So, there's just about nothing left in it. And, what's gonna happen? The pH of the water, the pH level of the water, it's gonna plummet.
And you're probably gonna have water about 6pH, OK? Now, you don't want to be drinking 6pH water. 7pH, that is neutral water, on the scale, and we'd love to have water, just a little bit above 7, and beyond for some people who like the high alkaline. But we really want to have people consuming water above 7pH, so as they're consuming the water, it's not stripping mineral out of their body, and it's not slowly creating an acid inside your body, OK? So, we'll start with this little one here Water's coming in.
As I've showed you here, it's going through the sediment, it's going through the carbon cartridge, and it's going through the membrane. This is a four stage. And this is the important part for us to remember. A four stage water filter, sediment, carbon, membrane and then it's filtered, then the water goes through a carbon cartridge, to polish the water up, ready for us to drink. And we're consuming that water. But that water, it still seeks pH. A lot of doctors will send people to us to get these, if they're sick, or they've got to flush themselves out, or they want to clean out inside. You can use this one.
But in my best shot and knowledge, is after a few months, it's done its job and you don't want to continually keep drinking acidic water all the time, OK? So, this model here, and this model here, exactly the same, except this one's got a large American alkalizer on the top, And this thing will be like, mineral stones, tourmaline, ceramic bowls, and then alkaline ceramic bowls, infrared inside, and mineral to add back to the water, to elevate the pH of the water. That's the objective.
That's what the job of this alkalizer here is to do. The water comes out of this system, the same as this one, seeks pH, but then it goes through this alkalizer, picks up the mineral, elevates the pH of the water up, and with this big USA Omni Pure One, probably more like to eight and half pH when it's new, and then you're consuming the water. I'd much prefer our customers to be drinking this one here, at eight and a half pH, and then slowly coming down over the life of the cartridge, over the next 12 months, might get down to seven, whatever, and then you can get yourself a replacement and start again.
But I'm not big on people using four stage ROs, and they're consuming acidic water, OK? And there's a couple of them on our site, all right? The AquaPro Under Sink Four Stage RO. It creates acidic water at a pH of six. People want them, people use them. Try and pass the word out, that that's the fact. We much prefer people to have an alkalizer on the top of their RO systems to add the mineral back in the water and elevate the pH. Now, I'll show you over here on this one here.
So, a typical four stage water filter like this, under the sink, is probably gonna look, a bit like that. One, two, three, four, OK? Water comes sediment, carbon, membrane, go through a carbon cartridge on the top, and you're drinking the water. That's a four stage. And, it's still acidic, the same as these two here. So what happens on this one here, the Xtreme 7, which is a very popular water filter, and the couple of reasons I like it, cheap to replace these first two cartridges on the bottom, and that's a bonus because, they're the two that take the brunt of the water. If you're on ball water, and you're using one of these, the Xtreme 7's great for that.
Sediment, carbon, 30 bucks for replacement and you're good to go. So, what we're doing here. Filtering the water before the membrane, through the membrane, and then the water's coming out this end of the membrane here where I am, OK? And, basically, it comes up, and it's going to go into this extreme alkalizer. So this is an alkalizer. Same as this alkalizer, just smaller, OK? So the water comes through the alkalizer, that's elevating the pH in this system up to 8.5, a lot of magnesium in this one, up to 8.5. You can also get the hydrogen one in the Xtreme 7 nowadays. So it will elevate the pH up, and we'll have water coming out of here, at about eight and half pH.
Swings up the top, and then you've got the infrared balls, good for acidity in the body, and a lot of health benefits there for us people. Then the water goes through the top carbon cartridge. These carbon cartridges polish up the water, and make it nice and sweet and good for us to drink again. So, that's the difference. If you cut it off here, and you just go with the four stage, you're going to be drinking acidic water. You check our alkalizer, and another cartridge on the top to elevate the pH, and you're good to go. Obviously, the Xtreme 7's also got the negative magnet on the end, which sort of makes that a lot better as well, OK? So that's a beauty.
The Aquasana, probably got one of the best mineralizers around. Basically, because it uses about four or five different minerals. And, it's NSF certified. Now, the Aquasana's designed to bring the water back up to the seven mark. So, if you took a test on this Aquasana system, after the membrane, it too will be producing water that's got a pH of around the six mark, acidic. But it does have a remineralizer. Not an alkalizer, it's a remineralizer. And, that does elevate the water back up to 7 pH. So, when you're looking at an RO system, have a look, yell out if you need a hand. But, try and get yourself something that's at least, a five stage, OK? So, five stage is going to give you sediment, carbon and then then the membrane three, an alkalizer four, and a carbon cartridge to polish it up before you drink at five. And if you achieve choose that.
This one here is a five stage, so if you can achieve that, you'll be good to go, and be very happy. Thank you very much.
