G'day folks. Rod from My Water Filter here today, and what we're gonna do is just have a quick look at the differences required for filtering some rainwater versus filtering town and city chlorinated, treated water, okay? So my preference is always the rainwater, because it hasn't had anything added to it. By that, I mean chlorine and chemicals, et cetera, but with rainwater, there's still some treatment required, depending on how you're storing your water and what's going on at your home, alright? So rain lands on the roof, into the gutter, and into your tank, okay?

So these problems associated with rainwater are generally sediment, and that comes out of any tank, whatever you've got. So a prefilter is a good idea, okay? A sediment prefilter will take the lumps and bumps out of the water. This can be outside on the whole home, and then you don't need it under the sink or up on the kitchen benchtop at your filter.

But if you've got no filtration prior to your home, I would use a prefilter if I was drawing rainwater into the home. The second stage is basically the bugs have gotta be stopped, okay? And heavy metals, lead on the roof, flashings, the water can be a little acidic, so it can be eating out the copper pipe, so you can have a lot of copper coming in as well.

So the ultra-pure cartridges, the Coldstream cartridges are fantastic for rainwater, because they'll remove those heavy metals and the herbicides and the pesticides and block the bugs, because they're a ceramic cartridge, okay? So that's normally where we'll go is with a ceramic for the bugs. Then, if you've got a concrete water tank, well the lime tends to leach out of the walls of the concrete and mix with the water, and that will elevate the acidic rainwater up to a neutral pH around the seven mark, so when water's neutral, it's not eating into the copper pipe on the home or attacking the home appliances, and it's good for you, too.

So we always want people to be drinking the water higher than seven, so if you've got a concrete tank, you could simply have a prefilter and a Coldstream or an ultra-pure water filter, just a twin system like that, you'd say, and you'll be good to go. Lime's coming out of the concrete walls and elevating the pH of your water. If you have a other type of water tank, now this could be poly nowadays are used a lot, the bolt-together steel tanks with the big liner bag inside, basically any other form of water tank except concrete, there's no lime leaching out of the walls, so you've got no interaction, no way to elevate or alter the pH of the water. So at that point in time, it's good to have a third cartridge, alright? And that third cartridge, there's a couple of different ways you can go.

We have a pH neutralizer, okay? Mostly calcium in the water, so we're neutralizing the water, elevating the pH just up to seven, just so people are drinking neutral water, alright? And then following that, you can see this filter here, this has got an alkahydrate cartridge in it. So this got a 10-inch drop-in cartridge in here, full of all different sorts of minerals. This is more likely to elevate the pH of the drinking water up to nine when they're new, slowly come back down eight, 8.5, and that will fade away over time, but these will give you a much higher pH-level than a pH neutralizer, alright? So there's two styles there. So that's pretty simple for rainwater, and as I say, there's a little bit of heavy metal could've come off your roof, the paint, maybe the copper out of the pipes, herbicides, pesticides blowing there in the wind, alright? Not a whole lot of contamination with rain water, so a great way to go, if we treat it right, and we get a beautiful product flowing out the tap, alright?

Now government water, town water, city water starts like this, starts as rainwater, but there's a lot of people living in our cities nowadays, and it's obviously a super big challenge for the government and our local shires, et cetera to keep the water supply to everybody's home. A growing population makes it harder every day, so the water being delivered to your home by the government, it is of a reasonable quality, but there's a lot of chemical in it. Obviously they throw that chemical in it so that they can deliver that water to your home, and it's not eating out the water pipe systems on the way, so you go to your tap in a capital city or a country town, generally the water's gonna be between seven and eight, and more likely, 7.2 to 7.5, something like that, pH.

It does alter, don't get me wrong, but generally all across Australia, that's what we find, that's a fair range, alright? So government's pumping water, generally with a pH just above seven, so that the pipes aren't getting eaten out, okay? They're not gonna pump acidic water through their pipes. It would be craziness, alright? So you're always generally gonna have alkaline water, pH-neutral water coming to your home, and that is okay to drink, and you're good to go from there. The problem is the chemicals and the extras that are added to the water, and also the associated pipelines that deliver the water to your home. So when you go and get a glass of water out of the tap in the capital city, that water's not just coming from the tank outside or off the roof, you know?

It could be coming from 20, 30, 40, 50 miles away. It could've traveled miles through those water pipes, and some of that infrastructure, unfortunately, could be pretty old, I got no idea what you could be drinking out of those pipes, alright? So it's always good to have a point-of-use filter where the water's filtered, and the next thing, it just comes out of the filter, into your tap, into your glass, you know you're covered. Same with this one under the sink. You know you're covered. It comes out the filter straight to the faucet, you're drinking it, way to go.

So in the capital cities, for years people have liked the old twin, alright? So forget everything on the top of this system. This is a reverse osmosis water filter, and it has a tank that goes with it. And the reason I've got this here is 'cause this is what I use nowadays, folks, okay? So I've gone away from the mechanical filtration. Still use this on the farm. No problems there with the rainwater, but when I'm at home in the city, we are using reverse osmosis, okay? So to give you a bit of an idea with this system here, the water's coming in, and it's coming into a sediment cartridge very similar to this one here, okay? Lumps and bumps, dirt, sediment in city water as well, no doubt about it, so we get the lumps and bumps out.

Then this part here, this is the chemical remover, okay? Get the chlorine and the chemical nasties out, herbicides, pesticides, et cetera, pretty similar to what this cartridge is doing over here. So these two here are pretty much doing exactly what these two cartridges did here. Now when the water gets out of this cartridge, if you're in the city, unfortunately, it's not the best it can be, alright? It just isn't, I promise you that, so what we've got on top here now, and to give you an idea, these are five micron cartridges in the bottom here, okay, five micron.

This membrane on the top, this filters down to 0.0001 micron, so no virus, anything. This membrane here is splitting the water. This water filter does use a bit of water, 50/50 type scenario, so it is using some water down the waste drain, but that's all your contamination that you're not drinking. You can use it on the garden, do whatever you want to do so you're not wasting the water, but it does split the water to use it, to create the best water. So once the water goes through the membrane, that's when it's pulling out the fluoride, the pharmaceuticals, the ladies' pill, fire retardants, just hormones, all this crazy stuff that we see in stories and news articles on now, and test results flying out every now and again of what's being found in our waterways, and unfortunately, water's clear, and water always looks beautiful, but it's just not the case, okay? It does require a test to know what we're consuming.

So once the water comes through this membrane, it drips everything out the water, and I mean mineral as well. Now that's been a problem for people sometimes. Oh, I don't want a water filter that takes the mineral out. Well, honest truth, I don't either, but I guess where we're at nowadays is, you've got the choice. You can use a filter like this in the city, and it's gonna leave the mineral in, but it's also leaving all those other nasties I just mentioned a minute ago, okay? Versus this one, take the whole lot out, and then once we've got it all out, and we're back to a base product, then we can start again, and we've got a big mineralizer on the back of this product here, add tourmaline and calcium and other good minerals for our health and also to elevate the pH of the water.

So this system here's got an alkalizer on it, and it's gonna deliver water at about nine pH, slowly come back to eight, and slowly fade away every year or so. And obviously this on top's the big carbon. It's just to polish the water up, make the water taste beautiful when you drink it, and I promise you, these ROs do create very fine, very tasty water, and they are ideal for the capital cities and larger country towns nowadays, and we really do recommend them, okay? So have a look. Give us a yell if we can help you in any way. Give us a question, an email, whatever. Always happy to chat and help you out, so good luck and have a good day.
