We additionally examined the Brita Full Faucet Filtration System. In distinction to the opposite mannequin within the Brita lineup, the Primary Faucet Filtration System, it enables you to set the tap to each a standard circulate and, moreover, a sprig sample. That additionally units it aside from Pur’s filters, which lack the spray possibility. Past that function, nevertheless, we a lot favor the Pur Superior mannequin. Pur’s faucet filters have considerably extra ANSI/NSF certifications. The Brita filter can be not licensed for mercury, whereas the Pur filters are. In our testing, the Brita persistently dripped, which led to a pink movie on the filter housing, presumably the micro organism Serratia marcescens, which is commonly present in damp sinks and showers. (The water was draining out of the saturated filter; the tap doesn’t leak.) Lastly, the Pur Superior has a lower-profile design and a modern form that we like a lot better than the Brita Full’s blocky, upright kind.
