I used a basic Brita pitcher for years assuming it was removing “contaminants.” Then I read the fine print on the filter packaging: the standard Brita filter removes chlorine taste and odor, some sediment, and not much else. It does not remove lead. It does not remove PFAS (forever chemicals). It does not remove bacteria or viruses. I had been paying for better-tasting water, not safer water.

That sent me down a research rabbit hole. What I learned is that “water filter” is an unregulated term and most pitchers are doing the bare minimum. A few, however, are certified to remove the things that actually matter.

What the Certifications Actually Mean

Look for NSF/ANSI certifications on the packaging or the manufacturer’s website. The ones that matter for drinking water: NSF 53 (reduces lead, cysts, asbestos, VOCs), NSF 401 (reduces emerging contaminants like pharmaceuticals and BPA), and NSF 473 (specifically reduces PFOA/PFOS — the two most common PFAS compounds). If a filter only has NSF 42, it reduces chlorine taste and odor only. That is a cosmetic filter, not a safety filter. The standard Brita falls into this category.

Best Overall: ZeroWater 10-Cup Pitcher ($35)

ZeroWater is the only pitcher filter certified to NSF 53 and NSF 401 that consistently removes lead, chromium, and PFAS down to undetectable levels in independent testing. It comes with a TDS (total dissolved solids) meter so you can test your water before and after filtering — the filtered water should read 000. The downside: filters cost about $15 each and last for roughly 20-40 gallons depending on your tap water quality (the included TDS meter tells you when to change). More expensive per gallon than Brita, but Brita is not removing lead. You get what you pay for.

Best Budget: Brita Elite (Formerly Longlast) Filter ($20 Pitcher + $17 Filter)

Brita’s Elite filter (the blue one, not the white standard one) is certified to NSF 53 for lead reduction. It does not have NSF 401 or 473 certification for PFAS, but third-party testing shows it reduces some PFAS compounds — just not as thoroughly as ZeroWater. One Elite filter lasts 120 gallons (about six months for a household of two). That makes it the cheapest per-gallon option that still removes lead. If lead is your main concern and PFAS is secondary, this is the best combination of cost and protection.

Best Premium: Clearly Filtered Pitcher ($75)

Clearly Filtered is independently tested to remove 365+ contaminants including lead, PFAS, pharmaceuticals, and fluoride (which most filters do not touch). The filter lasts about 100 gallons and costs $50-$55 to replace. The upfront cost is high — $75 for the pitcher plus $55 per filter — but if you have well water or known contamination issues, the peace of mind is worth it. It is the only pitcher I would feel comfortable using with well water that has not been independently tested.

Filters to Skip: Brita Standard and PUR Basic

The standard white Brita filter is NSF 42 only — chlorine taste and odor. No lead. No PFAS. The PUR Basic filter is marginally better (NSF 53 for lead), but the pitcher design has a known leak issue where unfiltered water bypasses the filter and drips directly into the reservoir. Consumer Reports confirmed this in testing. If you have a PUR pitcher already, the PUR Plus filter (the one with the blue wrapper) is the upgrade that actually filters properly. The basic one, skip.
