Our Verdict (Best For)

The PUR PLUS 11-Cup pitcher performed poorly in our 2025 filtration lab test, mostly due to potential leaching of barium and boron above strictest health guidelines (2024 was slightly better with only barium detected at levels below health guidelines). The taste of our water improved in 2025 with no odor, though some taste remained in 2024. The pitcher has a high count of NSF/ANSI-certified contaminants, but mostly for easier-to-remove organics. It is easy to set up and maintain, with a capacity large enough to fill a 40 oz bottle with a single refill – still fits in the fridge. There’s a flip-top lid for one-handed refills. Upfront and long-term costs are well below-average. More cons: A short 90-day warranty, a quite uncomfortable handle, tricky pouring, and a spout gap allowing unfiltered water to mix with the filtered. Overall, there are better pitchers on the market.

The PUR PLUS 11-Cup pitcher is designed for use as a drinking water filter and can purify both tap water and properly disinfected well water.

As usual, we’ve tested the pitcher with our own hands:

  1. Hands-on experience: We assembled, primed, used, and maintained it.
  2. Filtration effectiveness: Across 2 independent test rounds, we sent unfiltered and filtered tap water samples to professional laboratories for analysis to determine real-world contaminant reduction. Each round used a different pitcher, water supply, and lab. We also reviewed NSF/ANSI certifications and other available test data.
  3. More testing: We conducted taste and odor evaluations as well as filtration speed tests.
  4. All other product aspects: We considered initial and long-term costs, warranties, additional features, frequent customer complaints, and more.

What We Like Most

  • Filtered water had a much better taste and no odor (2025 test).
  • Higher count of NSF/ANSI-certified contaminants but limited in regards to contaminant types mostly covering “easier-to-remove” organics.
  • BPA-free and dishwasher safe (without filter).
  • Straightforward setup with clear, illustrated directions and a YouTube tutorial video.
  • Fits in fridge shelves and door.
  • Big enough to fill a 40-oz bottle in one refill.
  • Flip-top lid makes it easy to refill with one hand.
  • Filter maintenance is easy also thanks to filter change indicator light.
  • Well below-average upfront price and estimated annual filter replacement cost (compared to other pitcher filters).

What We Don’t Like

  • Achieved poor results in our 2025 lab testing.
  • Barium and boron detected in filtered water at or above strictest health guidelines in our 2025 lab testing (testing the PUR PLUS 30-Cup Dispenser also showed potential barium and boron leaching).
  • Higher level of barium detected in filtered water in our 2024 lab testing (below strictest health guidelines).
  • Filtered water was odor-free but had some remaining taste (2024 test).
  • On-demand filtering takes patience.
  • Flat handle is not the most comfortable.
  • Tricky to pour at first without water running down the front.
  • Gap near spout allowed unfiltered water to leak into filtered water while pouring.
  • Only comes with a short 90-day warranty.
  • Third-party customer complaints about cracked plastic, the lid falling off while pouring, and clogged filters.

Full Analysis of the PUR PLUS 11-Cup

Filtration: 2.87/5.00

The PUR PLUS 11-Cup water filter pitcher scored 2.87/5.00 for filtration. How? Most importantly, it achieved poor results in our 2025 lab testing, a downgrade from its adequate 2024 performance. In our 2025 test, the filtered water had a much better taste than our tap water though not 100% perfect. In 2024, there was some taste remaining (no odor was noted in either test round). Finally, while the PUR PLUS has a higher count of NSF/ANSI certifications for contaminant reduction, these mostly cover “easier-to-remove” organics.

1. Lab Results: 2.78/5.00 (2025) & 3.98/5.00 (2024)

Remember that our before vs after lab comparison is not an exact science. It’s informational and subject to variability, inaccuracies, and interferences caused by natural fluctuations in water quality, accidental contamination, human error, instrumentation issues, and more. Furthermore, our lab-testing is limited to those contaminants present in our water supplies and at their respective concentrations. As such, it can only give us a general idea for how effective a certain water treatment product might be.

In our 2024 and 2025 lab tests comparing an unfiltered and a filtered tap water sample, the PUR PLUS 11-Cup pitcher could remove 8 undesirable impurities and contaminants to below the minimum detection level (so essentially to 100%): chlorine, bromodichloromethane*, bromoform, dibromochloromethane*, chloroform*, copper, lithium, and uranium.

The following substances remained in our water:

  • Barium increased by 1,200% in 2024 (at 0.13 ppm, it was still below the strictest EWG health guideline of 0.7 ppm) and by 2,271% in 2025 (at 0.965 ppm, it was higher than the EWG health guideline). This is extremely concerning for potential leaching at a level that may make the water unsafe to drink.
  • Boron decreased by a moderate 50% in 2024 but increased by an astounding 4,456% in 2025, which is highly suggestive of potential leaching. At 0.697 ppm, the concentration again exceeds the strictest health-based guideline we identified (5 ppm, WHO).
  • Also note: During our testing of another PUR PLUS filter cartridge in the PUR 30-Cup Dispenser as part of our countertop water filter comparison, both barium and boron were also detected in the filtered water above health guidelines, supporting the findings from our PUR PLUS pitcher lab results.
  • Strontium was reduced by a very high 94% in 2024. In 2025, it was reduced by a solid 72%.
  • Manganese was reduced by a poor 22% in 2025 (not present in 2024).
  • Nitrate was reduced by a minimum of 70% (solid) and up to 99% (very high) in 2024. In 2025, it was completely removed.
  • Fluoride increased by 20% in 2024. While it seems improbable that such a large increase could be the result of natural variability, it’s also unlikely that the PUR PLUS adds fluoride to the water, as there’s no fluoride-based filter media. In contrast to this underwhelming result, the PUR PLUS pitcher completely removed fluoride in our 2025 test, where we used a different lab method to measure fluoride. (We consider this method to be much more reliable compared to the 2024 method).

Finally, limescale/hardness was reduced by 99% in 2024 and by 90% in 2025. Therefore, the PUR PLUS should help protect your kettle and/or coffee maker from buildup.

Aside from contaminant reduction, we found 3 substances in our 2024 filtered water that were not present in the unfiltered water, suggesting potential leaching: iron (0.01 ppm), silver (0.07 ppm) and zinc (0.07 ppm). Iron and zinc are merely aesthetic impurities which only become relevant (e.g., impacting water taste) at a higher level (0.3 ppm and 5 ppm, respectively) than detected in our sample per the EPA secondary standards. Silver, on the other hand, neared but did not exceed its EPA guideline (0.1 ppm); while excess silver does not pose any health risk, elevated levels can still cause undesirable cosmetic effects (skin discoloration and graying of the whites of the eyes).

In 2025, silver and zinc also showed up in our filtered water, albeit at lower levels than the previous year (0.0012 ppm and 0.054 ppm, respectively). Our lab findings at first glance seem to contradict the PUR PLUS pitcher’s official performance test data which claims the reduction of zinc by 92.70%. However, this apparent discrepancy may be explained by differing test conditions: PUR PLUS feed water contained 10 ppm zinc whereas ours contained no measurable zinc; therefore, the amount we observed post-filtration is more consistent with trace leaching from the filter media rather than incomplete removal.

*In our 2025 lab testing, we artificially spiked our tap water with fluoride and nitrate because our new water supply contains neither. The nitrate solution, however, unintentionally contained chloroform, resulting in a test concentration of 1,670 ppm – far above realistic tap water levels (100 ppm is already considered high). Despite this extremely elevated concentration, the PUR PLUS removed all chloroform and other disinfection byproducts. This result is noteworthy on its own and is also why we did not re-test VOC reduction, unlike other pitchers that failed to fully remove VOCs (including chloroform) in our ultra-high chloroform test.

2. NSF/ANSI Certifications and Other Test Data

The PUR PLUS is certified for the reduction of 27 contaminants by the NSF against NSF/ANSI standards 42, 53, and 401 and by the WQA against NSF/ANSI standards 42, 53, and 401. Listed reduction rates include:

  • Chlorine (taste and odor – 97.50%)
  • Lead (99.40-99.70%)
  • Mercury (>96.40%)
  • Pharmaceuticals (94.30-96.80%+)
  • So-called emerging compounds including industrial chemicals/herbicides (94.50-99.00%+)
  • Microplastics (99.80%)
  • VOCs and other organic pollutants (81.10-98.30%+)

3. Filtration Process

The PUR PLUS filter cartridge utilizes particle filtration, granular activated carbon, and ion exchange resin. Particle filtration (mechanical filtration) acts as a sieve to trap solid (undissolved) impurities like sand, rust, and dirt. Activated carbon removes things like bad tastes and odors, chlorine/chloramine, disinfection byproducts and other organics, as well as certain metals. Ion exchange targets dissolved, unwanted ions in the water.

4. Taste and Odor Tests

In our 2024 test, the filtered water was odorless but had some taste remaining. In our 2025 test, the filtered water was odorless as well, and the taste was much improved compared to our tap water but not 100% perfect.

Usability: 3.30/5.00

The PUR Plus pitcher achieved a usability score of 3.30/5.00, based on its performance in the following categories:

  1. Initial system assembly including filter priming (1.00/1.00)
  2. Day-to-day use (1.60/3.10)
  3. Filter replacements (0.70/0.90)

1. Initial Setup: 1.00/1.00

Assembling the PUR Plus pitcher is very easy. The user manual provides clear, illustrated directions outlining each step. In addition, there is a tutorial video on YouTube for the visual learners.

Here’s a quick overview of the setup process:

  1. Soak the filter for 15 minutes, then rinse for 10 seconds.
  2. Hand wash the pitcher, lid, and pour tray with mild, soapy water and rinse well. (Remove filter light from the underside of the lid before washing).
  3. Insert the filter into the pour tray, push down and twist clockwise to lock.
  4. Hold reset button on filter light for 10 seconds until it blinks green.
  5. Fill reservoir with cool tap water and let it filter completely.
  6. Now your pitcher is ready to use.

2. Day-to-Day Use: 1.60/3.10

2.1 Speed & Water Capacity: 0.80/1.20

The PUR Plus pitcher is a mediocre choice for daily use – we feel there are better options if day-to-day practicality is your primary concern. On a positive note, its filtered reservoir (12.5-cup capacity) is generous and can store plenty of water, but it has a smaller feed (6-cup). Since the filtered capacity is more than double the size of the feed, you need to refill twice in order to top up the filtered reservoir. We estimate 5-6 daily refills for the average-sized US and US family households, which also happens to be average for the pitchers we tested.

In addition, the PUR Plus filters fast enough to meet the daily water needs of the average-sized US households, and it can handle thirst bursts. That said, on-demand filtering takes patience. In our 2025 filtration speed test, the pitcher could filter 4 cups in 11:14 min, though it was much faster in our 2024 test at 6:20 min.

Finally, the pitcher fits both on the shelves and in the door of a standard fridge (dimensions: 5″x10.5″x11″), and thanks to the sufficient feed and filtered capacities, you can fill a large 40-oz bottle with a single refill.

2.2 Handling & Pouring: 0.15/1.15

The PUR Plus feels fine in the hand, though we prefer a rounded handle over its flatter style. More importantly, we found it tricky to pour cleanly at first; water tends to run down the front of the pitcher until you find the sweet spot. With daily use and practice, we assume users would get the hang of it; however, there may be a bit of a messy learning curve in the meantime.

To add insult to injury, unfiltered water can leak through a gap near the spout, mixing with filtered water while pouring, so you definitely have to wait until all water has filtered.

Its weight including the wet filter cartridge is average compared to the other pitchers we have tested, coming in at 2 lb 4.6 oz. While heavier weight may indicate sturdier construction (e.g., thicker plastic) and/or more filter media (desirable for better filtration results), it also can make handling more of a challenge.

2.3 Refilling: 0.65/0.75

The PUR Plus is easy to refill with one hand thanks to its uncomplicated flip-top lid that opens by pressing the lifted edge near the top of the handle.

3. Filter Replacements: 0.70/0.90

Filter replacements are very easy, and this pitcher comes with a filter change indicator built into the lid to remind you when to do so. We assume the indicator is time-based.

Rated filter life is 40 gallons. Assuming 300 gallons of yearly water consumption for the average household, we estimate that you will have to change the filter 7.5x annually. Note: per the manufacturer, the filter lasts “up to 2 months.” Based on this estimate, you may only have to change the filter 6x yearly.

Costs: 4.78/5.00

Based on value for money, the PUR PLUS pitcher achieved a cost score of 4.78 out of 5.00, indicating it is relatively inexpensive for what it offers compared to competing pitchers (a score of 4.00 represents average value). Notably, both its upfront price and annual filter replacement cost are well below average compared to the other water filter pitchers we tested.

1. Upfront Price

As of September 16, 2025, the PUR PLUS pitcher is priced at $24.99, which is well below the $58.53 average across all the water filter pitchers we tested.

2. Long-Term Expenses for Filter Replacements

Based on 300 gallons consumption and a 40-gallon filter life, we estimate $70 in annual filter replacement costs, which is well below the $120.13 average across all the water filter pitchers we tested.

3. Product Warranty

The system is covered by a short 90-day warranty.

Additional

1. Looks

The PUR PLUS comes in two color options.

2. BPA-Free

The pitcher is made of BPA-free materials.

3. Easy to Clean

The pitcher is dishwasher-safe (the filter is not).

4. Frequent Customer Complaints

We read about issues with cracked plastic or the lid falling off when pouring. Other customers complained clogged filters.

We did not experience these issues first-hand.

Bottom Line: We’re Worried About Potential Leaching (3.34/5.00)

Filtration weighted at 60%, and usability and cost at 20% each, the PUR PLUS pitcher scored a final rating of 3.34 out of 5.00.

It is somewhat middle of the road as far as usability is concerned. It holds enough water and filters fast enough to keep pace with your daily needs, and is easy to set up, refill, and maintain. However, it’s a little messy to pour and not quite as comfortable to hold as some of the other pitchers we reviewed.

More importantly, we’re worried about the PUR PLUS’s results in our lab testing. Although it fully removed 8 contaminants, our 2025 results showed evidence of potential leaching of both barium and boron above the strictest health guidelines (we got similar results with a PUR PLUS cartridge tested in the PUR 30-Cup Dispenser). In 2024 testing, barium also showed potential leaching.

So even with its low upfront price and maintenance costs, the lab results make the PUR PLUS difficult to recommend.
