I believe the ceramic filters are white in color, mine comes with two black colored filters which I believe are the originals with the "pesticide"!! Also, the pair of filters that come with my unit are good for 6,000 gallons, I'm 72 years old and drink about 300 gallons per year so I'll be dead before it's time to buy new filters.
