Propur’s ProOne water filter pitcher uses a ceramic filter element, the ProOne® M G2.0, to supply clean and great tasting drinking water – at least that’s what Propur says (more on taste issues soon).

In this review, we’ll discuss the unit’s pros and cons, and give you our final verdict.

Propur ProOne Water Filter Pitcher – Key Features

The Propur pitcher is BPA + PVC-free and has an overall capacity of 0.92 gallons (3.5 liters), 0.41 gallons (1.55 liters) of that being reserved for the filtered water.

In other words, the pitcher does not get too heavy to lift and pour while providing enough storage for a small family.

According to Propur, the ProOne G2.0 filter can be used “with just about any water source including tap, lake, stream, river, pond and rain water”.

That being said, most other filter pitchers are only recommended to process tap water and therefore not suited for camping trips etc.

The pitcher is simple to set up, fits most standard refrigerators and is warranted for 90 days (limited) against defects in materials and workmanship.

Of course, the Propur can be used as a regular filter pitcher. If, however, you want to infuse your water with fruit simply remove, fill and reinstall the infusion tube.

ProOne Pros

First of all, the ProOne M G2.0 filter cartridge is among the top in the pitcher realm – no add-on filters required. It combines silver-infused ceramic, which helps to prevent the growth of bacteria, with media based on granular activated carbon (GAC).

In addition, Propur has done the most thorough testing of a filter element that we have seen up to this point.

Actually, to be more precise, the testing was conducted by an independent lab certified by the State of New Jersey Department of Environmental Protection. Testing requirements for NSF standards 42, 53 and P231 were met. However, certifications were not awarded as far as we can tell.

This is a summary of the lab reports that can be found on the official Propur website:

The filter removes/reduces

  • Dozens of VOCs – some to more than 99.9% but at least 95.0%
  • TTHMs (chloroform, bromoform, …) – 99.0% on average
  • Aluminum – 98.0%
  • Arsenic(III) and arsenic(V) – 99.7%
  • Lead – 99.9+%
  • Mercury – 99.9+%
  • Sodium fluoride – 97.5%
  • More than 40 different pesticides – at least 98.0%, except for endrin (86.9%), heptachlor epoxide (85%), PCBs (93.3%)
  • More than 50 semivolatile contaminants – 97.0% or more
  • Chlorine and chloramines – 99.9+%
  • Nitrites/nitrates – 99.9+%/98.2%
  • About a dozen herbicides – more than 90.0%
  • 16 tested pharmaceuticals – e.g. Ibuprofen (95.6%) and Acetaminofen (96.0%)
  • Coliform bacteria, cryptosporidium, giardia – 99.999+%
  • Radium 226/228, uranium and other radiological contaminants – 81.6% (84.1%)
  • Fluorinated organic acids, including PFOS & PFOA – 99.9+%
  • Various parasites – think spirulina – 99.999+%

What’s more, the filter reduces at least 99.9% of bacteria (Klebsiella Terrigena), viruses (Poliovirus 1 and Rotavirus) and cyst (Giardia Lamblia), but only for the first 50 gallons of use as per NSF Protocol P231 requirements.

Testing according to NSF Standard 401 for emerging contaminants has shown a reduction of BPA (99.9+%), estrone 86.5% and linuron (99.9+%) among a couple of others.

Another benefit is that the Propur pitcher retains almost 100% of the magnesium and potassium in your water. Calcium on the other hand is reduced by about 80% which is not optimal, but also not that big of a deal in our opinion.

About TDS

Filtering your water with the Propur pitcher, it might read higher in TDS afterwards. This is due to the filter releasing minerals into the water and does not necessarily indicate an underlying issue.

Generally speaking, we don’t consider TDS the best way to measure contamination.

Assembling the Propur filter pitcher is a matter of minutes. What’s important is that you remember to clean the lid, upper blue container and pitcher with mild soapy water (the parts are not dishwasher safe).

Also, hold the filter under cold running water for roughly 2 minutes and use the dark green side of the scrubby sponge that’s included in the package to scrub the white surface. Rinse well afterwards.

Now you can attach the filter to the blue container and insert the assembly into the pitcher.

Fill the upper reservoir with cold water and add the lid on top. What’s important is that you discard the first 2 pitchers of filtered water before use.


One ProOne® M G2.0 filter cartridge is good for up to 225 gallons. However, for the most effective fluoride removal the filter should be replaced every 6 months at the least.

Now, this is much more than what you get with most other pitcher filters. At the same time, replacement filters are pretty expensive.

If you notice a change in taste, smell or flow rate the filter needs to be cleaned. If you’ve cleaned a few times already replacement is the next logical step.

Speaking of cleaning, all you have to do is rinse the filter with cold water while scrubbing the white part as explained above. Rinse well and reinstall.

ProOne Cons

The Propur filter pitcher has 3 issues:

  1. Very slow filtration – Like every other filter pitcher, the Propur, too, relies on gravity to force water through its filter element. Well, this turns out to be a lengthy process which was to be expected considering that the filtration is very thorough. However, depending on the quality of your feed water it can take ages (one customer reported 30 minutes for a single cup). The water literally drips from the filter. This is why we recommend you buy a large glass container so you can filter water 24/7. Also, make sure to condition the filter according to instructions (see above). And if the lid sits too tight it might not allow air to flow inside for pressure compensation, which is something you want to keep an eye on.
  2. Flawed lid – It’s difficult to pour filtered water into a cup or glass without unfiltered water leaking in. And no matter how long you wait, some water always remains in the top chamber. Thus, you either have to lift out the blue container or you need one hand on the lid to push down when pouring. Definitely inconvenient and rather poor design when you consider the cost.
  3. Unpleasant taste – Some customers reported an unpleasant aftertaste in their filtered water. They had to run the filter many more times than recommended by Propur to get rid of it. Again, make sure to condition according to directions.

Last but not least, the Propur pitcher has a high price tag and, like we said, replacement filters aren’t cheap either. The good news is that returns are fast and easy.

Propur ProOne Review: Our Verdict

Water quality wise, the Propur ProOne pitcher is one of the best on the market with testing conducted for the effective reduction of dozens of harmful impurities.

On the downside we have slow filtration – most users say the wait is worth it – and the handling of the upper reservoir that could do with an upgrade + taste issues.

Taking into account the relatively high price, we rate the pitcher with 3.5 stars!
