Filter Pitchers and Replacement Filters

A household drinking water filter is designed for water that is already fit to drink; it is not intended for microbiologically unsafe water and does not replace a boil water advisory.

Eight listings, sorted by how specific their certification wording is. One names a body and the substances it covers. Five name a body without a standard number. Two name nothing at all. The difference between those three states is the whole point of this site.

Read this before any of it

No filter in this catalog makes unsafe water drinkable. Household drinking water filters are designed for water that is already fit to drink. They are not intended for microbiologically unsafe water and they do not replace a boil water advisory from your utility or health department.

If you suspect lead or contamination in your supply, the next step is your utility's Consumer Confidence Report, the EPA, and your local health department. It is not a purchase.

Pitchers and dispensers

Seven listings from 6 to 35 cup. Read the certification line before the capacity: one of the seven names no certifying body at all.

  • ZeroWater Pitcher, 10 cup
    Only listing here naming IAPMO

    IAPMO appears on one pitcher listing in this category. The others name NSF, WQA, or no body at all.

    ZeroWater Pitcher, 10 cup

    10 cup statedListed here at position 01

    The listing states IAPMO certification for lead, PFOA/PFOS, chromium and mercury, and a 5-stage filter.

    4253401

    No standard number is named on the listing. Not named: 42, 53, 401.The listing names IAPMO and names substances, but no NSF/ANSI standard number. Read the IAPMO listing for the exact claims rather than assuming 42, 53 or 401.

    A 10 cup pitcher whose listing names IAPMO certification and names the substances the claim covers, which is more specific than most listings in this category manage. It also states a 5-stage filter. Naming a body and naming substances is still not the same as naming an NSF/ANSI standard number.

    What the listing gives you

    • Names a certifying body and the specific substances in the same sentence
    • Only pitcher listing here that names IAPMO
    • 5-stage filter construction is stated
    • 10 cup capacity is stated plainly

    What it leaves open

    • No NSF/ANSI standard number is named, so the cells on the chip stay empty
    • Multi-stage filters tend to run slower than single-stage carbon
    • No filter life in gallons or months is stated on this listing

    Suits Someone who wants a listing that names both a certifying body and the substances.

    4253401

    No standard number is named on the listing. Not named: 42, 53, 401.The listing names NSF/ANSI without naming a standard number, so no cell is filled here.

    A 10 cup pitcher with a stated 200-gallon filter and a listing that names NSF without naming a standard number. The gallon figure is the useful part, because it is the number the replacement schedule is built on.

    What the listing gives you

    • 10 cup capacity is stated plainly
    • Names the substances the reduction claim is about

  • Brita XL Pitcher, 27 cup

Replacement filters

One listing, cartridges only. With a single item there is nothing to compare it against, so this page shows it as a card and does not build a comparison table for a group of one.

  • PUR Pitcher Replacement Filters, 4-pack
    Only cartridge-only listing in this category

    One listing here is cartridges without a pitcher. The other seven are pitchers or a dispenser.

    PUR Pitcher Replacement Filters, 4-pack

    2 month life statedListed here at position 08

    The listing states genuine PUR filters and an 8-month value pack.

    4253401

    No standard number is named on the listing. Not named: 42, 53, 401.The listing names no certification, so no cell is filled here.

    Four genuine PUR cartridges sold as an eight month pack, which works out to the two months per cartridge the pack length implies. There is no pitcher in this listing and no certification named in it, so this page compares it with nothing.

    What the listing gives you

    • Four cartridges in one purchase rather than four purchases
    • Stated as genuine rather than compatible
    • The pack length implies the per-cartridge interval without arithmetic
    • Buying ahead is the practical answer to forgetting the change date

    What it leaves open

    • This listing names no certification and no standard number
    • Cartridges only, so the pitcher has to already be a PUR one
    • Cartridges sitting in a cupboard still age

    Suits A PUR pitcher already in the fridge that needs a year of cartridges.

Side by side

There is one listing in Replacement filters, so nothing on this site compares it to anything. A single-row table would be a comparison with itself.

Care and the parts that are not negotiable

  • Change cartridges on whichever comes first, the stated months or the stated gallons. Manufacturers usually publish both.
  • A cartridge that sits unused in a wet reservoir is not the same as an unopened one in a cupboard.
  • If you suspect lead or contamination in your supply, the answer is your utility's Consumer Confidence Report, the EPA and your local health department, not a purchase.

Questions this category actually raises

Does NSF certification without a number tell me anything?

Very little. NSF/ANSI 42, 53 and 401 cover different things, and a listing that says only NSF certification has not said which one applies. This site records the absence rather than filling it in.

Can a pitcher make unsafe water drinkable?

No. Household drinking water filters are designed for water that is already fit to drink. They are not intended for microbiologically unsafe water and they do not replace a boil water advisory from your utility or health department.

What does a 200-gallon rating actually mean for me?

It is a stated capacity, not a calendar. Divide it by how much water you actually put through the pitcher and you get months. The filter life tool on this site does that arithmetic and prints the formula.

Why is there no ranking of which pitcher filters best?

Because these listings do not carry comparable test data, and inventing a performance order from marketing copy would be exactly the thing this site exists to argue against.
