I'll admit it. I'm partial to Berkey water filters. I've owned one for years, and I've been happy with it. It's the only brand of gravity water filter that I knew about when I bought it.
But then I came across Propur, a brand that's been giving Berkey a run for the money.
I noticed a lot of discussion about Propur in online preparedness forums. If preppers are talking about a water filtration product, I figured that I should pay attention!
So I decided to find out more.
I spent hours researching the Propur filter to learn everything I could about it. I looked at test results and specs and reviews by people who use it. And I was impressed.
There are several different sizes of Propur filters, but for this review I'm going to focus on the most popular one, the Propur Big. I'm going to talk about its effectiveness, how it works, and where you can get the Propur Big at a great price.
Since it's very similar to the Berkey and Alexapure filters, I'll also cover some of the differences between them.
You can click on a question in the quick navigation below or just go on and read the whole review.
How does Propur water filtration work?
The Propur Big is a gravity water filter. It consists of two containers that stack together. You start by pouring water into the top part, where the filters are.
Gravity pulls the water downward through the filters into the bottom container. There's a spigot near the bottom for dispensing the purified water.
There's no plumbing involved. You can set it on your countertop or on a table.
What is the Propur made of?
The container and the spigot are stainless steel. The filter element is granular activated carbon in a container of silver infused ceramic.
In case you're wondering about the silver, it's used because silver inhibits the growth of bacteria. You don't want bacteria growing on your filters!
Where are Propur water filters made?
The filter element is made in England. I was not able to find out exactly where the other components are made. I emailed Propur to find out. They told me that the system is "made from imported and domestic components and assembled in the US".
What contaminants does the Propur ProOne G2.0 filter element remove?
This is what impressed me the most about Propur. An independent lab tested the ProOne G2.0 filter element for all kinds of contaminants. The results show that the filter eliminates all or almost all of the following:
- volatile and semi-volatile organic contaminants
- heavy metals
- disinfectants and inorganic non-metallic contaminants (including chlorine, chloramine and fluoride)
- bacteria and viruses
- radiological contaminants
- blue-green algae (parasites)
Propur is one of the best filters for lead removal. The lab data shows that it removes 100% of lead. That's impressive!
As far as "good" minerals go, the filter reduces calcium somewhat (about 81%), but it does not remove any magnesium and only 2.5% of potassium.
Of course, it also takes out bad tastes and odors, leaving you with delicious fresh-tasting water.
Here are links to the third party lab test results for the ProOne G2.0 filter:
Chemical Reduction Test Report (testing to NSF Standards 42 and 53)
P231 Microbiological Reduction Test Report (testing to NSF protocol 231)
Emerging Contaminants Test Report (testing to NSF Standard 401)
Does Propur filter out microplastics?
Yes, it does. Lab test results from September of 2017 show that the Propur filter blocks 99.99% of microplastics.
Microplastics are tiny bits of plastic debris, 2.5 to 10 microns in size. It's considered an "emerging contaminant", meaning it's been detected in drinking water, but the health risk isn't fully known yet.
But there's no doubt that it's not a good thing to ingest plastic!
That's one less thing you'll have to worry about if you filter your water with Propur.
Is the Propur water filter NSF certified?
Yes. It is certified to NSF/ANSI Standard 42 for aesthetic impurities, according to the NSF website.
Although the ProOne G2.0 filter has not been officially certified to NSF/ANSI Standard 53, it does meet or exceed this standard for healthy drinking water. That's according to the independent lab tests mentioned above.
So you know your water is clean and safe.
What's the size of the Propur Big and how much does it hold?
It stands 21.5" high and has a diameter of 9.25". It has a capacity of 2.75 gallons. This makes it a good size filter for a small family or group of 2-4.
What other sizes of Propur water filter system are available?
The Propur stainless steel gravity filter comes in four sizes to accommodate different size groups. You can use this chart to compare the capacities and prices.
Propur also makes a pitcher system that uses the same filter element, but in a mini size. It also has a removable infusion tube so you can infuse the water with fruits or vegetables if you like.
What does the Propur Big filter system include?
It comes with:
- 2 stainless steel chambers.
- stainless steel lid.
- 2 ProOne G2.0 filters.
- stainless steel spigot.
- non-slip pad.
What accessories are available for the Propur filter?
You can buy a stainless steel wire stand for the system that raises it up by 5 inches. This makes it easier to dispense water into glasses and containers.
Another helpful option is a sight glass spigot that allows you to see how much water is in the holding chamber. Otherwise, you have to lift up the top chamber to see how much water you have left.
How long does it take Propur to filter water?
It takes 6 to 7 hours to filter 2.75 gallons with 2 filters. You can add a third filter to speed it up if you like.
It does take some planning ahead to make sure you have a steady supply. But after you've had it for a little while you'll figure out a routine that works for you.
Some people just fill it up at night and then in the morning they have a full container of water ready.
How long do Propur filter elements last?
The manufacturer recommends replacing the filters every 12 months.
It's possible that they could last a little longer or they might wear out sooner than that. It depends on the quality of the water you put in and how much you use it.
What is the cost per gallon for Propur filtration?
I asked a representative at Propur how many gallons of water a ProOne G2.0 can filter before it needs to be replaced. The answer was anywhere between 700 and 1,200 gallons per filter.
That means that a pair of ProOne G2.0 filters is good for 1,400 to 2,800 gallons.
Using the lowest price that I found for a pair of filters ($139), the cost per gallon works out to 5¢ to 9¢ per gallon.
This is for the cost of the filters, and doesn't include the initial expense of buying the complete system.
Propur vs Berkey: What's the difference?
Here are the differences that stand out to me:
- The Propur doesn't require additional fluoride filters like Berkey does. The ProOne G2.0 filter does it all. If your water isn't fluoridated then this doesn't really matter. If you want fluoride in your water, then you won't want to use Propur.
- You don't have to prime the filters. You just put the Propur filters in and you're ready to go. To me this is a big advantage. Priming the Berkey filters is not fun. I usually end up spraying water everywhere and soaking my clothes when I prime them.
- The top chamber doesn't have to be filled to the top to achieve the maximum flow rate. Berkey does.
- Propur comes with a stainless steel spigot. Berkey comes with a plastic one.
- The life of the filters is different. Propur filters last about a year. The black Berkey filters can last anywhere from 3-5 years, but the fluoride filters only last 6 months. Berkey filters can be scrubbed and reused for several years, but Propur filters must be discarded after one year.
I compared the test results with similar tests done on the black Berkey filter. There was little variation between the two. Berkey has a slight edge here, but to me the difference was negligible.
In most cases, we're talking less than 1% difference in total reduction of certain contaminants.

Propur vs Alexapure: Which is better?
Alexapure and Propur are more alike than they are different.
They look almost identical on the outside, except that Alexapure has a plastic spigot, and the Propur has a stainless steel spigot.
The Alexapure filter is carbon block encased in a shell made of a hybrid ceramic material. So, it's similar to the Propur ProOne G2.0 filter.
As far as effectiveness goes, they are almost equal, except in lead reduction. Propur reduces lead by 100%, but Alexapure only reduces it 96.4%. This is significant, because there is no safe level of lead in drinking water, according to the EPA.
Because of Alexapure's weakness in lead reduction, I would say that Propur is the better of the two.
Alexapure is a little less expensive than Propur, but it doesn't have a warranty - only a 45-day return policy on unopened products. That seems a bit risky to me.

How much does Propur cost? Where can I buy it?
The prices at Amazon can change without notice, so I don't include prices in my reviews. It's easy enough to find out the current price, though.
Or you might like to buy directly from the manufacturer, Propur USA. Shipping is free, and there are other payment options available, including PayPal.
Does Propur have a warranty?
Yes. It comes with a lifetime warranty on the stainless steel parts. The filters have a 1 year warranty.
What do buyers say about Propur?
What Buyers Liked
- Water tastes great
- Easy to set up and refill
- Filters water quickly
Didn't Like So Much
- Takes up a lot of counter space
Does Propur make a shower filter?
Yes, Propur does have a shower filter in its line of products.
The Propur ProMax shower filter removes or reduces many contaminants including chlorine and fluoride. Please see What’s the Best Shower Head Filter? for more details.
Summing It Up
I think the Propur water filter is worth considering if you're looking for a countertop water filter that removes every conceivable kind of contaminant.
It's great for everyday use at home or work.
And it's good to have on hand for emergencies.
It's also handy to have if you want a water purifier to take along when you travel. You could even take it on your next camping trip if you wanted to. You can dip water right out of a lake or stream and put it through the filter.
I think that's pretty cool!
If I didn't already have a water filter system, I think I would probably lean toward buying a Propur. It does a great job of purifying water and it's easy to use. Those no-prime all-in-one filters are a big plus in my book!
You can also find the complete line of Propur products at the manufacturer's website.
