The Clearly Filtered Water Pitcher meets
the Culligan 10-Cup Water Filter Pitcher
Removes more contaminants than any other pitcher, backed by third-party lab data. We tested it head-to-head against the Culligan 10-Cup Water Filter Pitcher ($35) across 6 key dimensions.
Clearly Filtered Water Pitcher
“Removes more contaminants than any other pitcher, backed by third-party lab data”
Culligan 10-Cup Water Filter Pitcher
“RO-level purity from a $35 pitcher with a built-in TDS meter to prove it”
Head-to-Head Breakdown
Strengths & Weaknesses
Clearly Filtered Water Pitcher
- Removes 365+ contaminants including PFAS, fluoride, and heavy metals, verified by BOS Water and Project Farm lab tests
- Medical-grade Tritan plastic with zero BPA, BPS, or estrogenic activity, confirmed by BOS Water's material safety analysis
- Third-party tested to 200% of rated filter life, so performance holds up well past the 100-gallon rating
- Slow filtration at roughly 13 minutes for two cups, per Project Farm's timed testing
- Prone to clogging if your tap water has high sediment, which BOS Water flagged from customer complaint data
- Unfiltered water can leak under the lid and mix with clean water when pouring at certain angles
Culligan 10-Cup Water Filter Pitcher
- Strips water to 0 TDS (reverse-osmosis purity) from a gravity pitcher, verified by Water Filter Guru's lab scoring it 9.33/10
- Built-in TDS meter lets you measure water quality before and after filtering, and tells you exactly when the filter needs replacing
- At $35 upfront, it costs a third of the Clearly Filtered and delivers comparable heavy metal and fluoride removal
- Filters last only 15-20 gallons, pushing ongoing costs to roughly 90 cents per gallon per Water Filter Guru's calculations
- Inconsistent on disinfection byproducts like chloroform, which BOS Water found reduced by only 41-86% in retesting
- Tiny 3.5-cup feed reservoir means three separate refills just to fill the bottom pitcher, which gets tedious
The Verdict
Our Bottom Line
The Clearly Filtered pitcher won because it removes more contaminants than any other pitcher on the market, and the lab data backs it up. BOS Water tested 14 pitchers head-to-head and ranked it first for overall filtration effectiveness, citing its ability to handle 365+ contaminants including PFAS (forever chemicals), fluoride, heavy metals, and disinfection byproducts. Project Farm threw heavily contaminated water at it and got safe drinking water out the other side, scoring it at the top for both clarity and fluoride removal.

- Households concerned about PFAS, fluoride, or heavy metals in municipal water who want the most thorough pitcher filtration available
- Buyers with a higher upfront budget ($90) who prefer lower long-term maintenance costs at $0.55/gallon
- Anyone who values medical-grade materials (BPA/BPS-free Tritan) and a 24-month warranty
- People who fill the pitcher in advance and refrigerate it, since the slow filtration speed requires patience
- Renters or apartment dwellers who cannot install under-sink or whole-house filtration systems
Culligan 10-Cup Water Filter Pitcher
The Culligan 10-Cup pitcher (built on ZeroWater's 5-stage filter technology) earned the value pick because it delivers reverse-osmosis-level purity from a $35 pitcher. Water Filter Guru scored it 9.33 out of 10, their highest pitcher score ever, because it eliminated 100% of detected health-related contaminants in lab testing. That includes uranium, fluoride, lead, and total PFAS. BOS Water ranked it second overall for filtration effectiveness, just behind the Clearly Filtered.
- Budget-conscious buyers who want lab-verified heavy metal and fluoride removal for under $40 upfront
- People who enjoy seeing measurable proof that their filter works via the built-in TDS meter
- Households with specific lead or uranium concerns where TDS reduction to zero provides peace of mind
- Buyers willing to replace filters frequently (every 15-20 gallons) in exchange for a much lower entry price
- Anyone transitioning from bottled water who wants an affordable first step into pitcher filtration
