[VIDEO] Coldstream 0.5 Micron Ceramic Water Filter Replacement Cartridge 10" x 2.5" - Product Spotlight

Good day folks, Rod from My Water Filter here today, and what I'd like to introduce you to is the Coldstream Ceramic Carbon Cartridge. This is a great cartridge since it's an all-arounder cartridge.

What you Need to Know

It can be used in a single-stage filter on its own or built into a system. It has some of the most fantastic test results we've ever seen, and that's why you can trust it and count on it. In Australia nowadays, you're not just removing chlorine from the water. Gone are the days of using just a good carbon block cartridge in Victoria, New South Wales, and Queensland because, now they're introducing chloramine into the water. This is why you need a decent cartridge to properly take care of yourself to get chloramine out of the water and this cartridge will do the chlorine and the chloramine 99.9%.

What This Product Does

Made by KLT Filtration in Great Britain. It's CTO, which means our chlorinated water’s carbon, taste, and odor are taken out. It goes well beyond that as well. In the test results, you'll see heavy metals, herbicides, pesticides, even pharmaceuticals, and hormones are filtered as well. It really does bite in and get all of those yucky, nasty contaminants out of the water that we want out nowadays.

Convenient and Comes in Sizes

This product is ten inches in size and is available in a nine as well so it's available for just most common, standard water filters. Even if you've got a single-bench top water filter, this cartridge will still go in.

What You’re Getting

What makes this product excellent is that on the outside is a ceramic outer casing and has a couple of washers in the top. They come well-packed in tubes and is provided with good installation instructions there detailing do's and don'ts. It's just a beautiful lookin' cartridge used in our ULTRAPURE Systems because it's good, and the test results are fantastic.

Easy Installation Process

It only has a hole in one end, so, if you're putting this cartridge into a bench top water filter, make sure that the hole goes down because the water penetrates through the side and comes out the hole and it's gonna go down and out.

If it's under sink, then it goes this way up. It has an instruction which says “this way up” on the cartridge. Hence, bench top will be the other way.

Few Key Points

The ceramic on the outside acts as a sediment cartridge as well. That's why these are great to put into a single-stage water filter housing because it has sediment protection on the outside.

Cleaning Process

If it does block up with sediments, you can simply take the cartridge out, get it over the kitchen tap and scrub it with a 100 grit sandpaper or a green Scotch-Brite scouring pad. The product is about five or six millimetres thick, so you can give it a red hot scrub. That will get the flow rate going again.

Filtering Process

Once it penetrates through the ceramic, this carbon and other medias inside are removing the carbons, the chlorines, the chloramines, tastes, and odors, etcetera. It will absorb all of that garbage and contamination out of the water for you.


Obviously, there's a couple of washers here that come with the cartridge and we install one on the top and one on the bottom here and then, you're good to go. This product is an absolute beauty, and it comes with good test results, so take a look on the page, check them out, and if we can help you out in any way, then just give us a call. We'd be delighted to hear from you. So, good luck, and thank you very much!
