Higher ratedRanked #1 in Best Water Filter Pitchers

Culligan with ZeroWater Technology Water Filter Pitcher

4.6

The Culligan with ZeroWater pitcher delivers exceptional contaminant reduction, particularly for heavy metals, removing 100% of lead, uranium, and arsenic. Reviewers noted its 5-stage filtration system excels in critical contaminant removal and includes a convenient TDS meter. However, the filter has a short lifespan of 20 gallons, requiring frequent replacements and resulting in high long-term costs. The pitcher's acidic, demineralized output and limited 90-day warranty are drawbacks. It's best suited for households primarily concerned with heavy metals, but those prioritizing PFAS removal should consider alternatives.

Strengths

— Removes 100% of heavy metals including lead, uranium, and arsenic
— Includes built-in TDS meter to measure dissolved solids
— Simple setup with no filter priming required

Watch-outs

— Filtered water has acidic pH and is demineralized
— Short filter lifespan of just 20 gallons (2-4 weeks)

Ranked #3 in Best Water Filter Pitchers

ZeroWater 3-stage Water Filter Pitcher

4.0

$28.49as of Jul 5

ZeroWater's 3-stage pitcher filter delivers on its promise to remove 100% of total dissolved solids, achieving zero TDS in hard water conditions like those found in Phoenix, Arizona. Reviewers noted its exceptional performance compared to competitors like Brita and PUR, which struggled to remove even 30% of TDS. However, the filtration process is slow, extracting only 0.8 cups per minute, and produces demineralized water with acidic pH. While it's among the most effective filters tested, its high maintenance costs and slow speed make it less practical for everyday use, though ideal for those seeking ultra-pure water.

Strengths

— Removes 100% of total dissolved solids (TDS) as claimed
— Excellent performance in reducing TDS to zero in hard water conditions
— 5-stage filtration system provides thorough contaminant removal

Watch-outs

— Filtered water has acidic pH and is demineralized
— Slow filtration rate of 0.8 cups per minute
— Highest maintenance costs among tested filters

How they stack up

Culligan with ZeroWater Technology Water Filter Pitcher

The Culligan pitcher surpasses the Brita Longlast in heavy metal removal, eliminating 100% of lead, uranium, and arsenic compared to Brita's limited contaminant reduction. However, it falls short of the ZeroWater 3-stage pitcher's ability to remove 100% of total dissolved solids and is less effective than the LifeStraw Home pitcher in removing parasites and microplastics. Its short filter lifespan of 20 gallons makes it more expensive to maintain than the Aquagear pitcher, which lasts 120 gallons.

ZeroWater 3-stage Water Filter Pitcher

The ZeroWater pitcher excels in removing total dissolved solids, achieving 100% removal compared to the Brita Longlast's limited effectiveness. It outperforms the Culligan with ZeroWater Technology pitcher in TDS reduction but is slower than the Aquagear pitcher and lacks the broad contaminant removal capabilities of the LifeStraw Home pitcher. While it delivers ultra-pure water, its acidic output and slow filtration rate make it less practical than the Aquagear pitcher for everyday use.
