Does a Brita or carbon pitcher remove copper?

Only if that specific model is certified to NSF/ANSI 53 for copper. Carbon alone is not a guarantee, but some pitchers do carry the certification. In our catalog the Brita Standard Pitcher and the PUR Plus Pitcher are both certified to NSF/ANSI 53 for copper, so the certification listing is what to check rather than the filter type.

Does boiling remove copper?

No. Boiling does not remove copper, and because it evaporates water it can leave copper slightly more concentrated. To reduce copper, use a filter certified to NSF/ANSI 53 for copper or a reverse osmosis system certified to NSF/ANSI 58.

Contaminant · Water

Copper

EPA action level 1.3 mg/L (Lead and Copper Rule). 3 of the water filters we score hold an accredited NSF, WQA, or IAPMO certification to reduce Copper, and 3 more market it with no accredited certification we could verify. A claim is not a certification.

What it is

Copper is a metal that enters tap water on its way to your faucet, not from the source. It leaches from copper plumbing, soldered joints, and brass fittings inside household and building systems, with the most copper showing up in water that has sat in the pipes overnight. Soft or acidic water tends to dissolve more copper from the plumbing it touches.

Why it matters

The EPA sets an action level of 1.3 mg/L for copper under the Lead and Copper Rule, the same rule that governs lead. Because copper comes from the plumbing rather than the source water, the level at your own tap can differ from your neighbor's even on the same supply. We score whether a filter is certified to reduce copper, not any health outcome.

What removes it

Look for certification to NSF/ANSI 53 for copper, or reverse osmosis certified to NSF/ANSI 58. The trap is that a carbon filter is not automatically a copper filter: a pitcher or faucet unit only earns credit here if copper appears on its certified contaminant list, which is exactly what we check. Some pitchers do carry NSF/ANSI 53 copper certification, so the certification listing is what separates them, not the filter type alone.

Reference: EPA Lead and Copper Rule, action level 1.3 mg/L; NSF/ANSI 53 (copper reduction) and NSF/ANSI 58 (reverse osmosis).

Scored filters certified for Copper

6.6
Waterdrop G3P800 Tankless RO
A tankless 800 GPD reverse-osmosis system IAPMO-certified to NSF/ANSI 42, 53, 58 and 372 for a broad contaminant list including lead, PFAS, arsenic, nitrate and fluoride.
5.9
PUR Plus Pitcher (7-Cup)
An affordable pitcher certified to reduce lead, mercury, microplastics and chlorine, though its 40-gallon filter needs frequent swaps.
5.6
Brita Standard Pitcher
An everyday ion-exchange pitcher certified for chlorine, copper, cadmium and mercury - but notably NOT certified for lead.

Marketed for Copper, but not certified

These scored filters market Copper reduction but we found no accredited NSF, WQA, or IAPMO certification for it - "tested to" is not "certified to." Absence of certification is not proof a product fails to reduce it, only that we found no independent verification.

6.1
iSpring RCC7 5-Stage RO
A 5-stage 75 GPD under-sink RO. The base RCC7 is NSF-certified for TDS reduction only - the lead, fluoride and arsenic claims belong to other iSpring SKUs, not this model.
2.7
LifeStraw Home Pitcher
A membrane-and-carbon pitcher marketed against bacteria, microplastics, lead and PFAS, but its claims rest on 'tested to' lab data rather than active third-party certification.
1.5
Great Value Water Filter Pitcher (HS528N)
A budget store-brand pitcher whose Walmart listing says 'Certified to NSF/ANSI 42&53' but names no certifier, number, or registry - an unverifiable claim that earns no certified credit here. No standalone filter price is published, so cost per gallon also can't be computed.
