Brita vs PUR replacement filter cost

If you bought a Brita or PUR pitcher and are now staring at the replacement-filter aisle wondering whether you're being slowly bled dry, this page is the honest math. The short version: pitcher refills are a real annual cost, the two brands are closer than the boxes make them look, and there's a TCO crossover where an under-sink filter starts making more sense than pitcher refills indefinitely.

This is a replacement-cost guide, not a buying guide for new pitchers. If you're shopping fresh, also read pitcher filter vs under-sink RO.

Filter lines and replacement cadence

Both Brita and PUR sell multiple cartridge lines at different price tiers. The difference between the lines matters for both cost AND what they certify against.

Brita

Standard cartridge — NSF/ANSI 42 (chlorine taste/odor) only. Replace every ~40 gallons or ~2 months for typical 2-person households.
Elite (sometimes called Longlast+) cartridge — NSF/ANSI 42 plus NSF/ANSI 53 for lead and certain other health-effect contaminants. Replace every ~120 gallons or ~6 months.

The Elite line costs more per cartridge but lasts roughly 3× as long AND adds lead certification. For households with any lead concern, Elite is the only Brita line worth buying — Standard isn't certified for lead.

PUR

Standard cartridge — NSF/ANSI 42 (chlorine taste/odor). Replace every ~40 gallons.
Plus cartridge — NSF/ANSI 42 plus NSF/ANSI 53 for lead, plus typically NSF/ANSI 401 for some emerging contaminants. Replace every ~40 gallons.

PUR Plus historically carries broader cert coverage than Brita Elite (the NSF 401 emerging-contaminants standard is uncommon at this price tier) but replaces more frequently. The per-gallon cost ends up similar — you trade longer cartridge life for narrower cert coverage, or shorter life for broader certs.

You can verify what any specific current cartridge SKU certifies against on WQA Gold Seal — Brita and WQA Gold Seal — PUR. Cartridge cert lines change occasionally as manufacturers reformulate — the database is the live source of truth.

Annual cost framework

The honest answer to "how much will I spend per year?" depends on three inputs:

Cartridge line you pick (Standard NSF 42 only vs Elite/Plus with NSF 53).
How much filtered water your household actually drinks in gallons per week.
Where you buy (Amazon subscribe-save, Costco multi-pack, drugstore single).

Approximate annual cost for typical households (single Brita-style pitcher, ~half a gallon to a gallon a day):

Profile	Cartridges/year	Annual filter cost (approx)
Single person, 2 gal/week, Brita Standard	5-6	$30 – $50
Two-person household, 4 gal/week, Brita Standard	8-10	$40 – $70
Single person, 2 gal/week, Brita Elite	1-2	$30 – $50
Two-person household, 4 gal/week, Brita Elite	2-3	$50 – $80
Single person, 2 gal/week, PUR Standard	5-6	$30 – $50
Two-person household, 4 gal/week, PUR Plus	8-10	$60 – $100
Four-person household, 8+ gal/week, Brita Elite	4-5	$90 – $130
Four-person household, 8+ gal/week, PUR Plus	15-20	$120 – $180

These are ranges, not point estimates. Subscribe-save discounts (typically 5-15%) and Costco/Sam's Club multi-pack pricing can shift a household down a tier. Single-cartridge drugstore purchases can shift you up.

The wide spread between PUR Plus and Brita Elite at high-usage households is the most consequential delta: PUR Plus carries broader certification but replaces 3-4× as often.

When you've spent enough on pitcher refills

If you're a multi-person household running through filters every 2 months on the PUR Plus side or every 6 months on the Brita Elite side, your 2-3 year cumulative cost lands in territory where an under-sink system starts making sense:

3-year pitcher TCO (4-person household, PUR Plus):    ~$400-$540
3-year pitcher TCO (4-person household, Brita Elite): ~$270-$390
3-year under-sink carbon TCO (NSF 53):                ~$200 (system) + $50/yr cartridges = ~$350
3-year under-sink RO TCO:                              ~$400 (system) + $100/yr filters = ~$700

Under-sink carbon with NSF/ANSI 53 reaches cost-parity with a high-usage PUR Plus household in roughly 2-3 years. Under-sink RO costs more upfront but addresses a broader contaminant set (arsenic, fluoride, hexavalent chromium, PFAS) — relevant only if your CCR actually shows those contaminants.

The crossover isn't just cost — it's also cert coverage. A $90/year PUR Plus household with no plans to upgrade is getting NSF/ANSI 42 + 53 + 401 at the pitcher. An $80/year Brita Elite household is getting NSF/ANSI 42 + 53. An under-sink RO household is getting NSF/ANSI 58, which covers a different contaminant set. Don't assume "more expensive cartridge = more capability"; verify per-product on the WQA database links above.

A bridge worth considering

If you're replacing pitcher cartridges often AND your concern is lead or PFAS specifically — not just chlorine taste — there's a case for upgrading to an under-sink stage even before you cross the cost-parity line. NSF/ANSI 53 carbon under-sink filters and NSF/ANSI 58 RO systems do not interrupt their reduction performance the way a pitcher cartridge does in the last week before you replace it. Pitcher cartridges' reduction efficiency drops as they approach end-of-life; under-sink systems with quarterly or semi-annual cartridge service stay closer to their rated reduction throughout the cycle.

This matters most for lead — where the EPA's health goal is zero — and PFAS, where any reduction is desirable. For chlorine taste, end-of-life cartridge degradation matters less.

If this applies to you, walk through the Filter Finder — it'll route you to the cert standards to look for at the under-sink tier given your specific situation.

What this guide deliberately doesn't do

Quote specific cartridge SKU cert standards. Brita and PUR reformulate cartridge lines periodically; what was NSF 401 last year might not be on the current SKU box. Verify any specific cartridge on WQA Gold Seal — Brita or WQA Gold Seal — PUR before buying based on a cert claim.
Tell you Brita is better than PUR or vice versa. They occupy roughly the same niche with different cartridge-life vs cert-coverage trade-offs. Picking depends on usage volume and which contaminants you care about.
Give exact per-cartridge prices. Retail prices vary across Amazon, Costco, drugstores, and direct-from-brand subscriptions; the prices on cartridge boxes in 2026 are not the prices in 2027. Use the ranges above as cost-tier guides, not invoices.
