Doulton W9223002 Ultra Carb Ceramic Filter Video Transcript
Hey everyone, Tony the Filter Doctor here. Today weíre looking at the Doulton W9223002. This is Doultonís Ultra Carb OBE ceramic filter element.
Now, OBE is an acronym that stands for Ďopen both ends,í and as you can see this filter element is open on both ends. Thatís because itís designed to fit into industry standard size drinking water housings, like for example the popular Culligan HF-360. So, this will fit into housings that take standard 10 inch by 2 Ĺ inch filter cartridges.
Now, the cartridge features Doultonís standard ceramic filter technology with imbedded silver. And itís important to note that this is not an impregnated silver. The imbedded silver is superior because it does not allow the silver to escape into your drinking water. But you want the silver there, because it causes the filter to be self-sterilizing and bacteriostatic so that microorganisms cannot live and grow on this filter media.
And then inside of the ceramic shell is an activated carbon block. Of course, activated carbon removes a long list of organic and inorganic contaminants, as well as a variety of VOCís, which are volatile organic compounds. And it also removes chlorine taste and odor and generally makes the water more palatable.
Then imbedded within the carbon block is an ion exchange resin, and this is designed to capture heavy metals like lead, which obviously you do not want in your drinking water.
This is a high quality filter. Itís NSF Standard 42 and 53 certified. Standard 42 pertains to the materials, and Standard 53 has to do with the capturing of microbial cysts and microorganisms. You see, the ceramic shell provides absolute filtration down to 0.9 microns, so that you get 99.99% reduction of microbial cysts like cryptosporidium and giardia, as well as 99.99% reduction of pathogenic bacteria like salmonella, e coli and cholera.
Now, in terms of filter life it really depends on what contaminant youíre most concerned with, because if youíre concerned about something that the carbon core is removing, the carbon core will be exhausted in approximately six months or 600 gallons. So if your concern is with lead, then you need to change the filter, replace it entirely at approximately six months or 600 gallons.
However, if youíre concerned with something thatís being captured by the ceramic outer shell, maybe itís sediment or maybe itís actually microorganisms, in that case the filter will last a very long time, and itís somewhat unpredictable how long it will last, because you can remove it from the filter housing and wash it and reuse it up to fifty times. Thatís probably the greatest feature of ceramic. Simply take it out of the filter housing, under running water take a green Scotchbrite and gently scrape the outer surface until it returns to itsí original creamy white color. Then install it and youíre back in business.
Again, this is the Doulton W9223002, the Ultra Carb OBE from Doulton, and Iím your host Tony the Filter Doctor.
