Two filters are available for any of DuPont’s pitchers – the Vista (6 cups, $36.25), Traditional (8 cups,comes with three lids in different colors, $21.50), and Deluxe. The larger Deluxe (13 cups) is outfitted with a dual filter, and the company calls it their premium product.
That double filter will process 120 gallons, and DuPont offers two types of filters for its pitchers: the Universal will handle 60 gallons before it needs replacing, as will the Ultra Protection . Both filters will also fit most Brita, PUR and Culligan pitchers, the company says.
On its website, Dupont offers detailed information about its products and certifications, including a list of contaminants its filters remove. The double filter lists the standard chlorine, particulates and metals, but adds lead, 1,2-Dichloropropane (a chemical solvent that is rarely used today), endrin (a pesticide/rodent killer not sold for general use in the U.S. since 1986), lindane (a pesticide banned in many countries and scaled back in the U.S.) and tetrachloroethylene (a dry-cleaning solvent that is carcinogenic), among others.
