G'day, folks. Rod from My Water Filter here today. And we're gonna have a quick look at the comparison between water filters: whole-house water filters versus point-of-use drinking-water filters. Do you need both, is one better than the other, what's the difference, OK? Honestly, I think you need both, and I'll tell you why, OK? This is a whole-house water filter. It's a great water filter, triple whole-house. Sediment in the first housing, and then carbon-carbide or carbon-aragon, OK, if we want to get the heavy metal, etcetera, out. Now, this is locked on the side of the house. All the water that's used in your home is going through this water filter. So, at times, it's going through at 20, 30, 40 liters a minute. And at that speed, we can stop so much. The chlorine and the chemicals, etcetera, pretty easy to stop, OK?
Got some really good cartridges nowadays, and we can hold back some heavy metals, etcetera. But there is an issue when the water gets out the other side of a whole-house water filter. It'll flow on to the shower, you have a beautiful shower, there's no chlorine gas in the shower. You'll have beautiful washing-machine water. Even the kitchen sink will have nice, hot water coming out of it. OK, don't get me wrong.
But there's a lot of pipework between the end of this water filter and where you actually consume your water. And old homes could have lead connections, and things like that, asbestos flashings, you just don't know. So the best, safest way to create the best water you can is always going to be with a point-of-use water filter. Now, that could be a simple gravity filter where you simply take a pot of water out of the sink, and you tip it into the top of the gravity water filter. That gravity water filter has got a candle cartridge in the top. That's going to filter the water at about 1 liter an hour.
Then we move on to reverse-osmosis systems. They're filtering the water at about 200 mils a minute. And then we can move on to a benchtop, or an undersink system, which is very similar to this one here. And that's gonna run at somewhere between two to four liters per minute. So if we compare the flowrates of these drinking-water point-of-view systems to the whole-house, this system here can be flowing up to 10 times as fast.
Now, to remove the real nasties from the water, it comes down to contact time with the media inside the cartridge, OK? And as you can see here with this triple, yes, you get two passes through quality cartridges, the water gets to pass through two quality cartridges, but it's going fast. When we want to get the fluoride out of the water, and the real nasties here, we've slowed the water right down, two liters a minute.
So we've got a lot of contact time between the water and the media. The media is able to do what it's supposed to do, and draw the contamination out of the water, and store it. So then the pure water will flow out of the spout and you've got good-quality drinking water to drink. So My Water Filter would recommend a whole-house water filter of some description. And then at the point-of-use, where you go to drink the water, so the water is filtered immediately before you consume it, we would suggest to have a good-quality, point-of-use drinking-water filter at that point as well. Thank you very much.
