PUR Water Pitcher Replacement Filter (4-Pack) Review 2026
PUR filters offer better contaminant reduction than Brita Standard at a similar price, especially for lead. The LockFit design is a genuine innovation. Solid choice for PUR pitcher owners.
Overview
PUR has long been Brita's closest competitor in the pitcher filter market, and the 4-pack replacement filter is where PUR makes its strongest case. At $23.22 for four filters ($5.81 each), PUR undercuts Brita Standard pricing while delivering better contaminant reduction — including NSF 53-certified lead removal that Brita Standard lacks. The proprietary LockFit design is PUR's standout engineering feature, creating a mechanical seal that prevents unfiltered water from bypassing the cartridge.
The 2-in-1 filtration combines activated carbon with ion exchange resin in a single integrated cartridge. This dual approach tackles both taste/odor contaminants (chlorine, sediment) and dissolved metals (lead, mercury) simultaneously. PUR certifies its filters to reduce 20+ substances, putting it firmly between Brita Standard (basic chlorine reduction) and Brita Elite (30+ contaminants) in terms of filtration breadth. For the price, it delivers impressive coverage.
The limitation is ecosystem lock-in. PUR filters only work with PUR pitchers, which have a smaller retail footprint than Brita. You will not find PUR pitchers at every grocery store the way you find Brita. However, the filters themselves are widely available on Amazon and at major retailers like Target and Walmart, so replacement availability is not a concern.
Key Features & Specifications
| Filtration Technology | 2-in-1 Activated Carbon + Ion Exchange |
| Capacity | 40 gallons per filter |
| Certifications | NSF 42/53 |
| Pack Size | 4 |
| Filter Life | 40 gallons (~2 months per filter) |
| Compatibility | PUR pitchers and dispensers only |
| Contaminants Removed | Lead, mercury, chlorine taste/odor, 20+ substances |
The LockFit design is worth highlighting because it addresses a real problem with pitcher filters. In traditional drop-in designs, water can seep around the filter edges if the cartridge is not perfectly seated, effectively producing unfiltered water mixed with filtered water. PUR's click-lock mechanism eliminates this issue mechanically. During our testing, we observed zero water bypass with properly installed PUR filters — something we cannot say about every Brita Standard filter installation.
Pros & Cons
What We Like
- ✓ LockFit design ensures proper seating — less likely to produce unfiltered bypass
- ✓ NSF certified to reduce 20+ substances including lead and mercury
- ✓ Competitive pricing at ~$5.81 per filter
- ✓ Better lead reduction than Brita Standard at a similar price point
- ✓ 4-pack provides 8 months of filtration
What Could Be Better
- ✗ Only compatible with PUR pitchers — not interchangeable with Brita
- ✗ Slower flow rate than Brita Standard filters
- ✗ Filters sometimes arrive sealed but with black carbon dust leaking
- ✗ PUR pitchers are less widely available than Brita
Performance & Real-World Testing
PUR filters produce clean, neutral-tasting water that eliminates chlorine taste effectively. In side-by-side tests with Brita Standard, the difference in taste was minimal — both handle chlorine well. Where PUR edges ahead is in documented contaminant reduction: the NSF 53 certification means lead reduction has been verified by an independent lab, not just claimed by marketing. Using a basic water quality test kit, we confirmed that PUR-filtered water showed measurably lower lead levels than Brita Standard-filtered water from the same tap source.
The 40-gallon filter life is on par with Brita Standard and tracked accurately in our testing. Each filter reliably lasted 6-8 weeks for a two-person household. Flow rate is slightly slower than Brita Standard — expect an extra minute or two to fill a full pitcher. The slower flow is a consequence of the denser media needed for lead reduction. Across 19,000+ Amazon reviews, the 4.5-star rating is strong, with the most common complaint being the carbon dust issue on first use (easily solved by flushing) rather than any filtration quality concern.
Value Analysis
At $5.81 per filter with a 40-gallon capacity, PUR costs approximately $0.15 per gallon — nearly identical to Brita Standard ($0.11-0.15/gallon). But PUR's NSF 53 lead certification makes it functionally closer to the Brita Elite ($0.12/gallon at 120 gallons per filter) in terms of what it actually removes. This makes PUR arguably the best value in the pitcher filter market for lead-concerned households, delivering lead reduction at a Standard-tier price point.
The 4-pack provides 8 months of filtration at typical usage rates, which is a convenient purchase cadence — order twice a year and you are covered. The main drawback is ecosystem lock-in: you need a PUR pitcher, and switching away means abandoning that hardware investment. For new pitcher buyers, PUR is worth serious consideration over Brita Standard. For existing Brita owners, the switching cost (new pitcher) may tilt the math toward upgrading to Brita Elite instead.
