Just Go with the Flow

After months of advising my relatives to get a water filtration system, one of the families finally decided to purchase one.  I had told them about the Berkey, and they thought this is what they purchased.  Well… not really.

From what the family member told me, the booth at the trade show they attended had two filtration systems side by side:

1-  the clear Berkey Light, with the red food dye in the canister above, being filtered clear into the canister below, AND

2 – a stainless steel model right next to it which was not being tested.

They wanted a Big Berkey, the kind with the stainless steel housing.  The salesman started with,”This is just like the Berkey, but these Propur filters are designed to be much better…”  In the end, they paid $239 for the unit and took it home.  Now the adventure begins.  They opened the box, and found nothing was labeled, except for a couple of these small stickers that said “Propur,” and 1 page instruction sheet.  They wanted to make sure they assembled it correctly so they called me and asked me about Propur which I was not familiar with.

Before they arrived, I did a search on the internet and found the Propur website.  It appears Propur has positioned themselves to be a Berkey competitor.  I wanted a thorough review, but I did not find much information on the web.  Thus I decided to test it myself.  I am not an expert, nor I do not have any scientific water purification measures, but I’ve used enough water filters to do a road test.  I contacted ProPur’s Customer Service to see if they could send me published results (similar to what Berkey posted) but they just sent me back to the website.  When I asked where is the unit made, all I was told was “Europe” but nothing more specific.

We followed the assembly instructions exactly.  The steps indicated you had to filter two batches of water before it is ready to drink.  Not wanting so waste so much water we filled the top container about halfway with tap water.  We left it alone for about six hours.  After several hours, the water still did not seem to be flowing down.  Not much water was getting purifed.

I called up the seller on their receipt and explained the issue:  not much water is getting through.  The man who answered was not surprised.  He indicated the Propur water filter, when new, will not completely let any water through unless the top canister is completely full.  He said we needed to fill up the entire top canister and let it run through a few times; it may take three days for it to start flowing right.  He also said the top canister will never completely empty out; you will have to keep refilling the top canister close to the top for it to filter properly.  I feel this could be a problem in an emergency if you only have a little bit of water to filter.

Sure enough, once we filled it close to the brim, the unit started running the water through.  We refilled it one more time.  On the third fill up I tasted the water and it did taste better than tap water.   But I was still wondering about its purification abilities, and the amount of contaminants it could filter out.

What I Found Out

After a while I found Debunking the Alternative Choice.  The article does not name names but I am sure who the “alternative choice” is, as they themselves claimed their comparison to Berkey all over their website.  I also ran across the informative article Water Filtration Facts-Pay Attention to the Nines.  In looking at the results posted,  Berkey clearly has more 99.9999% of contaminants covered.

After 4 hours, this is the amount of colored water filtered.

It took over 24 hours for the top container’s orange water to get filtered through.  The resulting water did look clear, and was good tasting.  It also worked well with tap water, as long as you keep the top canister full.  However, this final test tells me if I were actually purifying dirty water in an emergency, these Propur filters would take a really long time.  And in an actual emergency, time is something you may be short on.

Ultimately the family who bought the filter decided to keep the stainless steel container since it works okay, but will replace the filters with Berkey’s.  In my opinion, if you are in the market for a water filter, make sure you are getting the real article.  Some final tips:

  • A few dollars price difference is not worth the frustration and lack of confidence.
  • Research the system thoroughly before you buy
  • Review the list of contaminants and pay attention percentages of substances removed
  • Find out the unit’s about flow rates:  in an emergency you will likely be purifying unclean water which may potentially slow it down considerably
  • Purchase from a reputable source.
  • Find out about return policies.

    • Thanks JacLynn. There are just so many details to take into account when getting a water filter, I did not even think about flow rates until this experience. Thanks!

  1. This type of filter is fairly good if you are are going to be stationary, and as you mention, have a larger amount of water available to filter. My recommendation is for a smaller hand pump unit. I prefer the Guardian units by Cascade Designs. They are a bit pricey, but you get what you pay for. They have a lifetime guarantee, and have many accessories to fit any need. Most of all, they are highly portable (fits in a coat pocket) and efficient, and can filter water right out of a puddle if needed. They are even used by the military.
    Check them out, they are worth a look.

    • Hi John in Iowa, In an emergency a unit that can filter water right out a puddle can be a lifesaver. Good to know, I will have to look at those Guardian Units. Thank you!

      • The thing that must be remembered with water filters is that if it filters good, the water will flow though it slower. Katadyn makes a Base Camp unit that is a bag with a ceramic filter in it that you hang on a tree after it is filled. The problem is that it takes several hours to filter the water through it as well. All drip filters are like that, if they filter good. If you have the time to wait on them, they are pretty effortless, but they are bulky and not very versatile.
        A hand pump unitlike the Guardian, increases the pressure on the water to force it through the ceramic filter faster with lesser amounts of water needed. All ceramic filters are pretty good, and the Guardian has filter add-ons that boost their efficiency, such as an iodine cartridge that connects to it to kill viruses (ie;Bird Flu). There are lots of neat but necessary things including spare filters, water bottle adapters, and etc. They make a lower priced unit called a WalkAbout that I haven’t tried, but I’ve heard it’s a good starter unit.
