Spigot dispensing
Moderate filter cost

Review

What to know about PUR DS1811Z (PUR PLUS 30-Cup Dispenser)

A slim 30-cup fridge dispenser with a spigot. It uses the PUR PLUS filter that PUR says is IAPMO-certified for Total PFAS, and PUR's footnote says the claim applies to both pitchers and dispensers. It is the high-capacity choice for families who want PUR's PFAS-certified filter.

Editorial notes

Why it stands out

Why we like it

It uses the same filter that TapWaterData lists as IAPMO-certified for Total PFAS, and PUR says the claim covers pitchers and dispensers. No lab has tested this dispenser itself, so its PFAS result is carried over from the 11-cup pitcher's test.

The 30-cup capacity and spigot suit big households, and it is sold by Amazon at a mid-priced level. Annual filter cost matches the pitcher at about $108.

What to know

Skip it if you want a true pitcher or have little fridge space. Check that the listing includes a PUR PLUS filter.

Performance

Score breakdown

PFAS reduction evidence

Strength of proof that the system cuts PFAS: a current NSF/ANSI 53/58 PFOA/PFOS or total-PFAS certification (NSF, WQA or IAPMO) and/or independent lab results (TechGearLab/Tap Score, Quality Water Lab). Certified plus lab-verified scores highest; marketing-only claims score lowest.

8.3

Certified filter; lab results carried over from the 11-cup pitcher, not tested in this unit.

Other contaminant coverage

Certified or lab-verified reduction of lead, chlorine/chloramine, VOCs, pharmaceuticals (NSF 401), microplastics, and for RO, TDS, fluoride, nitrate and arsenic.

7.8

Same filter: lead, microplastics and PFAS, but little fluoride reduction.

Value

Upfront price plus annual filter cost per gallon, judged against the protection delivered.

7.0

$39.99 sold by Amazon, plus about $108 a year in filters.

Installation & cabinet fit

DIY difficulty, whether it needs a drilled faucet hole, a drain saddle or an electrical outlet, renter-friendliness, and under-sink footprint (tank vs tankless).

6.0

Dispenser, not a pitcher; needs a fridge shelf edge to reach the spigot.

Flow & daily convenience

Flow rate or production speed, filter-change ease, and filter-life reminders.

7.0

Spigot and big reservoir mean fewer refills. The 40-gallon filter goes quickly in a big household.

Health, materials & sustainability

Lead-free component certification (NSF 372), BPA disclosures, wastewater ratio, energy use, effects on pH and minerals, and any media leaching found in lab tests.

6.5

Plastic; keeps minerals.

Reliability & support

Leak reports, warranty length, availability of replacement parts and filters.

6.5

Sold by Amazon; filters widely available.
