10-Cup Ready-Pour Water Filter Pitcher

Score: 7.4/10 | The ZeroWater pitcher satisfies the desire for measurable, visible proof that filtration is working. The included TDS meter showing "000" is genuinely compelling. However, families should understand that zero TDS comes at a cost: frequent filter replacements that add up quickly.

This review uses R3's Water Filter Methodology v1.0.0.

ZeroWater holds NSF 53 certification with 99.6% lead reduction, matching or exceeding most competitors. For families with older plumbing, this level of protection matters.

The 5-stage ion exchange technology removes virtually all total dissolved solids. Your water reaches "000" on the included meter. This includes minerals, salts, metals, and dissolved chemicals.

Important context: Zero TDS does not equal "purest" or "safest" in all ways. Some dissolved minerals like calcium and magnesium are beneficial. ZeroWater removes everything, which some families prefer while others consider a drawback.

ZeroWater markets PFAS reduction but lacks NSF P473 certification. Third-party testing suggests 70-90% PFAS reduction, better than basic carbon filters but below the 99.9% achieved by NSF P473 certified options like Clearly Filtered.

Standard chlorine taste and odor reduction is confirmed by NSF certification.

The free TDS meter is ZeroWater's distinguishing feature. Test your tap water (typically 100-400 TDS), then watch it drop to "000" after filtering. For data-driven families, this provides satisfying confirmation.

Here is the critical trade-off. ZeroWater filters exhaust based on your water's TDS level:

• Low TDS (under 200): ~40 gallons per filter
• Medium TDS (200-400): ~25-30 gallons
• High TDS (400+): ~15-20 gallons

In hard water areas, a family of four may need new filters every 1-2 weeks.

The built-in spout allows pouring without lifting the pitcher, helpful when full.

Competitive with other premium pitchers. Includes one filter and the TDS meter.

This is where ZeroWater becomes expensive. Assuming medium-hard water:

• 30 gallons per filter, 3 gallons daily use
• ~36 filters per year
• $15/filter = $540/year

Even with bulk pricing ($10/filter), annual costs reach $360.

The ZeroWater pitcher delivers on its promise: zero TDS with measurable proof. The included meter provides compelling visual confirmation. However, families should budget for frequent filter replacements, especially in hard water areas. For most families, the Brita Elite offers better long-term value, while Clearly Filtered provides superior PFAS protection.
