Doulton W9330958 Under Sink Filter System Video Transcript
Hey everyone, Tony the Filter Doctor here. Today weíre looking at the Doulton W9330958. This is Doultonís under sink filter system, featuring the Super Carb ceramic filter element.
Now, this system comes complete with an installation kit and a drinking water faucet, so this is perfect for those of you who are installing a brand new system and want all of the connections pieces and the drinking water faucet.
Now, as I already indicated, this system features the Super Carb ceramic filter element, which features Doultonís standard ceramic technology with imbedded silver. You see, Doultonís imbedding process is superior to the typical silver impregnating that other manufacturers use. This will not allow the silver to escape the ceramic, and obviously thatís a good thing because you donít want it in your drinking water. But you do want in the ceramic because it causes the filter to be self-sterilizing and bacteriostatic, so that microorganisms cannot live and grow on this filter media.
And, of course, the ceramic is very dense, providing absolute filtration down to 0.9 microns, which equates to 99.99% reduction of microbial cysts like cryptosporidium and giardia, and the same level of protection for pathogenic bacteria like salmonella, e coli, and cholera.
Now, inside of the ceramic shell is a carbon block core, and of course, activated carbon removes a vast list of organic and inorganic contaminants, as well as a variety of VOCís, which are volatile organic compounds, and of course, chlorine taste and odor.
Now, beware that the carbon core will exhaust after approximately 600 gallons, but the ceramic outer shell will last well beyond that. In fact, one of the greatest features of ceramic filters is the reusability factor. You can wash and reuse them approximately fifty times. Simply remove it from the filter housing, and under running water take a green Scotchbrite and gently scrub the exterior surface until it returns to itsí original creamy white color, then reinstall and youíre back in business.
Now, I point this out for a couple of reasons; the big reason being, it really depends on what contaminants youíre removing in order for you to determine filter life. If youíre only concerned with chlorine taste and odor, or maybe you have some VOCís, then youíre going to need to replace the filter after 600 gallons even though the ceramic outer shell is not replaced because the carbon core will be exhausted. But if your primary concern is with sediment and perhaps microorganisms of some kind, well then the ceramic shell will last and last and last and give you very very long filter life. So you need to know which contaminants are your primary concern in order to help you determine filter life.
Now, the entire system is NSF Standard 53 cerrtified and thatís because the filter does remove 99.99% of microbial cysts, as Iíve already indicated. And itís NSF Standard 42 certified for material requirements, because the housing is 100% BPA free being manufactured from an acetyl polyester, and all of the metal components are lead free.
So you can count on this being a high quality system that gives you the performance youíre looking for and removes a high level of contaminants.
Again, it is the Doulton W9330958, and Iím your host Tony the Filter Doctor.
