ProOne Pitcher – Key Features

The ProOne Water Filter Pitcher features a powerful filter element with a ceramic outer shell and proprietary carbon-based granular media inside the core. The filter element is called the ProOne G2.O M.

The filter is cleanable and reusable and has a lifespan of 6 months or 225 gallons. It removes VOCs, THMs, pesticides and herbicides, heavy metals, chlorine/chloramine, fluoride and other salts, PFAS, microorganisms, and other stuff – really solid and all tested to NSF standards (more on this below)!

The ProOne Water Filter Pitcher further includes a removable fruit/vegetable infusion tube and has a filtered water capacity of 6.75 cups. It comes with a 30-day risk-free guarantee and a 120-day warranty.

ProOne Water Pitcher Pros

As mentioned before, the ProOne pitcher uses cleanable, reusable filters that last for about 6 months or 225 gallons – this is much longer than most competitors and ensures that you spend less on replacement filters. A ProOne filter cartridge costs $41.95, so annual filter replacements only cost ~$85, which is pretty good.

What’s more, the ProOne’s unique design prevents cross-contamination between the filter elements and the filtered water. Most water filter pitchers have their filter elements sitting in the filtered water, potentially leading to cross-contamination. But with the ProOne pitcher, the filter sits upright in the container, out of the filtered water. This position reduces the chances of cross-contamination, ensuring the purest possible drinking water.

Another thing we like about the ProOne is that it’s made from BPA and BPS-free food-grade materials. Plus, ProOne filters retain most beneficial minerals in the water.

What Contaminants Are Being Removed?

The ProOne Water Filter Pitcher has been independently lab-tested to remove over 200 contaminants. We found the lab reports online. Here’s a summary of the contaminants removed and their reduction rates:

  • Dozens of Volatile Organic Contaminants – Up to 99.9%
  • Total Trihalomethanes – Up to 99.9%
  • Dozens of Pesticides, Herbicides – Up to 99.9%
  • Lead – 99.9%
  • Arsenic 3 and 5 – 99.7%
  • Mercury – 99.9%
  • Nickel – 99.3%
  • Chromium 3 and 6 – 98.7%
  • And many other heavy metals
  • Dozens of Semivolatile Contaminants – up to 99.96%
  • Chlorine – 99.9%
  • Chloramines – 99.9%
  • More than 90% Fluoride
  • Nitrates – 98.2%
  • Nitrites – 99.9%
  • Pharmaceutical Drugs – ~95%
  • Several bacteria, cysts, and other parasites – 99.999%
  • Few viruses – 99.99%
  • Around 80% of radiological contaminants
  • Forever Chemicals – 99.9%
  • Microplastics – 99.999%
  • So-called emerging contaminants (BPA, TCPP, Linuron, Estrone, and Other) – up to 99.9%
  • HAA5 – up to 99.8%

A certified independent lab has tested the ProPur filter to NSF/ANSI standards 42, 53, 401, P231, and P473. The results show not only really solid contaminant reduction rates but also lots of contaminants tested for. There are only a few water filter pitchers that can compete with this.

Installation

The ProOne pitcher is easy to set up and use, and its filters require no priming. Here’s how to assemble the pitcher:

Please consider these instructions as a general guideline. Always make sure to check and follow your user manual before getting started.
  1. Take the pitcher out of the carton and put the filter cartridge aside.
  2. Clean the pitcher with mild liquid detergent soap (also clean the lid and upper blue container). Do not put the pitcher in the dishwasher. Once you’re done cleaning, dry the pitcher with a soft cloth.
  3. Take the filter out of its packaging, then unscrew the wing nut from the filter stem (keep the washer on the stem). Hold the filter’s plastic base with one hand and position the filter under running tap water.
  4. Next, rinse and scrub the filter for 2 minutes (don’t put the filter stem directly under the faucet).
  5. Place the stem through the hole in the upper blue container and connect the wing nut to the filter stem on the underside of the upper blue container. Secure the wing nut snugly, but don’t over-tighten.
  6. Fit the upper blue container into the pitcher.
  7. Pour cool tap water into the upper blue container and insert the lid. The first water cycle will take more time due to the filter conditioning process.
  8. Discard the first two batches of filtered water.
  9. The pitcher is now ready for use!
  10. To take out the fruit infusion tube, simply unscrew it by turning it counterclockwise. Put your sliced fruit or vegetables into the infusion tube, then turn clockwise to reattach the infusion tube.
  11. Fit the upper blue container back into the pitcher and fill the upper blue container with cool water.
  12. Secure the lid and allow water to filter through before use.

The Package (Parts)

  • ProOne Water Filter Pitcher
  • ProOne® G2.0 M Filter Cartridge

Maintenance

As mentioned before, ProOne® G2.0 M filter cartridges are cleanable and reusable, so you don’t spend much on new filters. Annual filter costs are about $85, which is pretty good. Here’s how to clean the filters:

  1. Unscrew the wing nut to remove the filter from the upper blue container. Ensure that there are no leaks into the blue stem of the plastic base.
  2. Carry the filter by its base and place it under a stream of running water for 2 minutes.
  3. While holding the threaded stem, place the filter in a bowl of water or under cool running water and scrub the surface with the dark green side of the scrubby sponge included in the package. Scrub away from the threaded stem end of the filter and not towards it.
  4. Rinse the filter and reassemble it. Do not wash the filter with soap or cleaning detergents.

You’ll need to replace the filters before they get too old to maintain the pitcher’s ability to remove total dissolved solids and produce great-tasting water, which is usually every 6 months or 225 gallons.

NSF and Other Certifications

The G2.0 M series filter cartridge is certified for NSF Standard 42 (for material requirement only). This certification has nothing to do with contaminant reduction.

Earlier Product Versions

ProOne used to be Propur. Aside from that, there are no earlier versions of this product as far as we know.

ProOne Filter Pitcher Cons

There are a couple of cons with this water filter pitcher. For one, it’s not the most affordable out there. Also, it has a short 120-day warranty — some brands offer a lifetime warranty.

Its NSF Standard 42 certification is for material requirements only. We would have liked some official NSF certifications for contaminant reduction.

Filtered water capacity is also low — only .42 gallons.

Finally, some past users complained that the pitcher takes too long to filter water. There were also a few complaints about the pitcher leaking unfiltered water along with filtered water.

ProOne Pitcher Review: Our Verdict + Best for

The ProOne Water Filter Pitcher has been tested for over 200 contaminants with impressive reduction rates. The price is on the higher end, but considering what the pitcher offers, we think it’s worth it. The annual maintenance costs are also in an acceptable range. However, we would have preferred some NSF certifications over independent testing. We would have also liked a higher water storage volume and a longer warranty. Overall, we rate this a solid 4.5 stars.

Our Rating in Detail:

  • Filtration Performance: 4.5/5.0
  • Filter Capacity (Life): 5.0/5.0
  • Purchase Price: 4.0/5.0
  • Annual Cost: 4.5/5.0
  • Overall: 4.5/5.0

ProOne Water Filter Pitcher

ProOne

Price: $$$
Filter Process: Ceramic Shell, Carbon Core
Filter Capacity: 225 gal
Storage Volume: 6.75 Cups
Annually: $73.95

Overall Rating: 4.5/5.0 ⓘRating based on filtration performance, filter life, price and yearly cost, NSF testing/certification, customer support, product warranty, our testing/experience, user feedback, and other factors.

The Clearly Filtered is miles ahead of many pitcher models in the market. It’s been third-party tested against NSF standards 42, 53, and 401. The results? Over 350 contaminants removed! It’s undoubtedly the most cutthroat testing we’ve ever seen for a water filter pitcher, and the results are outstanding.

The Clearly Filtered removes common contaminants like chlorine and chloramine, and other ones like lead, VOCs, DBPs, arsenic, PFAS, chromium-6, pesticides, fluoride, pharmaceuticals, semivolatile compounds, radiologicals, and so on.

In comparison to the ProOne Pitcher, the Clearly Filtered has higher reduction rates and is tested for almost twice as many substances. However, the ProOne outshines the CF pitcher at removing bacteria, cysts, and other pathogens — the CF pitcher is not tested for those.

The Clearly Filtered Pitcher’s filtration process includes the use of different proprietary filter media and granular activated carbon. The CF’s filter life is 100 gallons or around four months — shorter than with the ProOne.

The Clearly Filtered has a total storage volume of 17 cups and a filtered volume capacity of 10 cups — more than the ProOne offers. It also outshines the ProOne with its 30-day satisfaction guarantee and a limited lifetime warranty.

The Clearly Filtered Pitcher has a removable lid that makes refilling a lot easier. It’s made of 100% BPA-free material and is built in the USA. The only downside to the Clearly Filtered Pitcher is its high price. It’s more expensive to buy and maintain than the ProOne.

The Epic Pure/Nano Pitcher is another good system, slightly more budget-friendly than the Clearly Filtered, and costs around the same as the ProOne.

Epic Pure handles fluoridated tap water, while Epic Nano is designed to tackle microorganism-containing well water (these organisms could be cysts, bacteria, and few viruses). Epic Pure and Nano pitchers are interchangeable, so you can swap one with the other when the need arises.

The Epic pitchers filter out contaminants using a blend of activated carbon and proprietary filter media. This approach targets over 200 contaminants in water. Epic filters are NSF-tested against standards 42, 53, and 401 (Epic Nano has additional testing against P231 for microorganisms).

What’s removed? Chlorine, fluoride, chloramine, arsenic, pesticides, mercury, pharmaceuticals, lead, sulfate, nitrate, hexavalent chromium, VOCs, cadmium, disinfection byproducts, PFOA, PFOS, and a whole lot more.

Epic Pitchers have a built-in countdown timer that reminds you of filter replacement dates, and the filters have a long lifespan of 150 gallons (this is still less than the ProOne filters).

The total storage of Epic pitchers is 14.8 cups. Its filters are manufactured in the USA with BPA-free materials.

Epic pitchers are covered by a lifetime warranty and a stress-free return policy. Epic offers discounts to military personnel, seniors, first responders, teachers, students, medical staff, and owners and employees of non-profit organizations. There’s also Epic’s recycling program, where you get a new filter in exchange for four used ones.

Bottom line: The Clearly Filtered Pitcher has our number one spot. In terms of filtration, it’s the best of the three. Nevertheless, Epic and ProOne filters are also effective. They were both tested to remove over 200 water contaminants, including microorganisms. Deciding between the Epic and ProOne pitchers is really tough since they’re both solid. In the end, you should pick a pitcher based on your preferences.

Ira Beeber says November 16, 2023

The ProOne, and Epic Nano, and Clearly Filtered, do not remove Nitrates as claimed. Sent samples of all three to a lab and it showed very minimal reduction of Nitrates. Spoke to all 3 companies and they said “nitrates are hard to remove”. ProOne gave me the best explanation that I was able to check out. They told me that certain contaminants may block the removal of other contaminants. Most filters will remove Sulfates before Nitrates. I have Sulfates in my water at about the same concentration as my Nitrates. The filters are removing the Sulfates, but leaving the Nitrates. I’m waiting for an Alexapure Pro filter to see if I can get better results with the Nitrate removal.

    Hi Ira, thanks a lot for sharing!
    These companies test their products’ contaminant reduction capabilities under standardized lab conditions. So when testing for nitrate removal, for example, there’s nothing in the water but nitrate, and there is a specific level of nitrate. Of course, this is usually not the case for people on a real-life water supply and results can be different as you have experienced. So while obviously not being optimal, we still consider this standardized approach to be the best. Otherwise, companies could simply come up with their own testing methods and there was no way for us to verify the results.
    I hope this makes sense!
