When it comes to more specific contaminants, however, differences between the Brita and ZeroWater start to emerge. With its 5-stage filter that includes ion-exchange fibers, the ZeroWater is able to remove more Total Dissolved Solids (TDS) than any other pitcher filter on the market. It’s also the only pitcher filter certified by the NSF to remove both lead and chromium.
However, it should be pointed out that many drinkers actually prefer some level of TDS in their tap water. Water that’s lacking in mineral salts may be tasteless and have a slimy, unpleasant texture.
As for the Brita, it beats the ZeroWater filter for reducing important (but rare) health risks such as asbestos and cadmium.
There are a couple of contaminants that some pitcher filters can tackle, which neither the Brita nor ZeroWater cover. One of these is Cysts—small pockets in water that can house microorganisms and parasites. Whether you actually need a pitcher filter capable of removing cysts is something you’d likely already know, but if you do, we’d recommend going with the Pur Ultimate 11-cup versus either of the two filters featured in this review.
ZeroWater ZD: N/A
Brita 10-Cup Pitcher: N/A
