Doulton W9121709 Video Transcript
Hey everyone, Aquaman here with FilterDoctor.com. Today weíre looking at the Doulton W9121709.
Now, every Doulton filter features this self-sterilizing ceramic outer shell with imbedded silver particles. Itís important to note that this is not an impregnation of silver, but rather the silver particles are imbedded within the ceramic and therefore cannot escape; unlike an impregnating procedure which would allow for the silver to escape from the filter media. This is a superior process and will not allow silver to be added into your drinking water. And the silver is important, because it causes the filter to be bacteriostatic and self-sterilizing.
Now, perhaps the greatest feature of these ceramic filters is that they are reusable. You can wash this filter and reuse it up to about twenty times. Simply remove it from the filter housing, and under running water use a green Scotchbrite to lightly scrub the outer surface until its fresh and creamy white like it was when it was new. Then reinstall and youíre back in business.
The W9121709 is a proprietary type cartridge designed specifically for Doulton gravity fed systems. Itís easy to identify a gravity fed filter because it has a significantly longer threaded nipple than those filters made by Doulton that are designed for the pressurized drinking water systems.
Now, this cartridge is a Super Sterasyl cartridge, which means of course, it has the standard ceramic shell and then inside of the shell is a granular activated coconut carbon, designed to reduce things like chlorine taste and odor, pesticides, herbicides and VOCís; while the ceramic outer shell provides absolute filtration down to 0.9 microns, reducing 99.99% of microbial cysts like cryptosporidium and giardia and 99.99% of pathogenic bacteria like salmonella, cholera, e coli and many others.
Again, this is the Doulton W9121709, Super Sterasyl, and Iím your host Aquaman with FilterDoctor.com.
