This is because the AlexaPure shows itself to be reliable and affordable. It has all the same benefits and features as the big Berkey. For instance, it can become portable meaning that you can use it home or even when outdoors camping.

Buying the AlexaPure means that you’re also buying into the story behind it. Alexa Pure originates from a young couple (Matt Redhawk and family) who were expecting and planning for their first child.

They designed the AlexaPure out of concerns over potential future events and emergencies. The idea of ​​an affordable, reliable and highly efficient water filter was motivated by these concerns.

Today, there is an AlexaPure family of products. This includes everything from water filter pitchers and water bottles to air filters. The air filter version is called “AlexaPure Breeze” and there is also the “Survival Spring” option, which are similar to the Lifestraw or Sawyer Survival Water Bottle.

However, in this article I will only provide you with an AlexaPure Pro review. By the end of this review, you will know if the manufacturers claim stack up and whether it’s worth it.

Alexapure Pro Cleaning and Care

Your AlexaPure Pro is created so that it needs very little maintenance.

However, there are a few things you can do to make sure you always get the best results from your water filtering system. The manufacturers recommend the following:

  • Change the filters regularly: Doing this ensures that your drinking water remains clean, contaminant-free and healthy. There are no filter replacement indicators as such but you should keep a filter change schedule. Or immediately replace the filter cartridge if you notice a drastic change in the flow rate of your water.
  • Cleaning the outside of the filter: The mineral content of the raw water can accumulate in the hybrid ceramic housing unit of the AlexaPure system. While this will not have any effect on the filter or filtration process, it’s worth cleaning the filter surface. Remove it, rub with a soft cloth and water (no soap). Be sure to rinse well and then put back into the upper chamber.
  • Routinely clean the whole unit: The exterior surfaces of your AlexaPure Pro stainless steel chambers are easily kept clean with a soft cloth. Rinse the interior with fresh, clean water before using for the first time.

Once you put all the parts together. Pour water through one time to rinse through. And then finally water and let gravity do the rest.

Why AlexaPure Might Be Better?

The AlexaPure is sometimes referred to as a Big Berkey BK4X2 knockoff.

Now, this is NOT because it’s a cheap knockoff but because the Berkey was on the market first.

Berkey has the advantage of being the most recognizable brand. It has a strong reputation, great customer reviews and a certified filtering capacity.

Berkey still rules and is the industry standard for stainless steel gravity countertop water filters.

AlexaPure Pro WORTH it?

The short answer is yes.

But it’s not as effective as the Big Berkey counter top filter system.

Mr Water Geek ThinkingHowever, AlexaPure is ideal for people that are on a budget and still want something that will work similar to Berkey.

It removes toxins from water and provides you with clean, healthy and delicious drinking water on a daily basis.

It does this by combining carbon block filtration power with a hybrid ceramic shell.

AquaTruThe result of this is that it can remove up to 99.99% of many harmful contaminants. This includes a number of things like disinfectants, VOC’s and even hormones.

Apart from affordability, the AlexaPure Pro is portable, lightweight and non-electric.

This makes it ideal for every situation including emergencies.

However, it’s not always available and there are some rumours that the AlexaPure has been discontinued.

Dashed Line


  1. My worry with the Black Berkey filters is the threading on the filter stems and the nuts that tighten against those stems. I stopped using the Berkey filters because the stem and/or nut thread was so flimsy it stripped half the time I tightened the filters in place. The AlexaPure filters use a thread and nut that is VERY robust and have NEVER stripped on me. If the threading and nuts have improved and no longer strip when tightened, I would give the edge to Berkey. If not, the threading and nuts on the AlexaPure and Doulton water filters are your safest bet. It doesn’t matter how well the filter filters if you cannot get or trust the seal between the filter and the dirty water chamber.

  2. I hope my review will help somebody to avoid my mistake. I don’t recommend Alexapure at all. I can’t say anything bad about filters, because I used the system for a very short period of time. However, the parts of Alexapure system are of a very poor quality. You may buy a good filters but the parts will leach chemicals back to your filtered water. I was comparing Alexapure and Berkey. It seemed to me they are almost identical in terms of filtration and i decided to buy Alexapure. I assembled everything the first day after it arrived. The plugs that cover the holes in the upper chamber are made of a very cheap, extremely stinky rubber. The next day when I checked Alexapure system I noticed a rust on the bottom of the upper chamber and because that rust was on the outside of the chamber, it dripped into filtered water. It happened after 1 day of use! The second unpleasant surprise was that filtered water tasted like those stinky rubber plugs. I contacted the company immediately and asked for a return. They tried to persuade me that rust in stainless steel is a normal thing :)) and also I need to soak stinky plugs in baking soda mixture to reduce the odor. I decided to send it back. I packed all parts carefully, put all filters in millar bags with distilled water. When I contacted them again they told me I need to pay for the shipping myself. I paid $45 to send it back. Then I was waiting for a refund for more than 1 month and when I finally received it, it turned out the refund is $75 less than I paid for Alexapure system. They said it’s a fee for disposal…… I ended up buying Berkey system. I don’t have any complaints about Berkey so far.

    1. Hi Nancy

      Products like this need to meet certain minimum standards before they can be sold to the general public.

      So I think it’s unlikely that something like this will leach metals into the water because there are lots of laws in place to make sure that this is not the case and it would be breaking the law if it did.

      Stay hydrated,

  3. Is Alexapure available in California to but? I know Berkey is not. Will they give us the results of California water testing which is what I go by even in Ohio.

  4. Luke, I have compared the data on both and one BIG issue is that Berkey does not filter out nitrates. Living in the midwest myself, we have an extreme amount of nitrates in our municipal water due to runoff. Alexapure filters nitrates at >98%. This is concerning to me that so many believe berkey is better and there are people drinking an absurd amount of nitrates in their water. Also, Alexapure was tested up to 200 gallons and Berkey tested up to 50. And if you read carefully, Berkey requested to not include Cryptosporidium in their testing, whereas Aquapure does and it’s removed 99.9%.

    1. Danae, Where did you get that information about nitrates and Cryptosporidium? I’m researching now and I’m finding research that says that berkeys do filter them as well as aquapure.

  5. Hi Luke, we are trying to find a water filtration system for our weekend cabin. None of the reviews I’ve found discuss intermittent usage (mostly weekends and a week here and there throughout the year). Can you provide some insight? Thank you so much!

    1. Hi Wendy

      The only issue that I can see is that the water would become stale if you left it for a very long time.

      Therefore you would probably need to thoroughlly clean the unit and replace the filter cartridges before using it again.

      Stay hydrated,

  6. What do you mean when you say the Alexapure is not ‘as effective’ as the Big Berkey? I’m trying to decide which to buy and this statement, combined with your review, is confusing. Please clarify what you mean. Thank you.

    1. Hi Cathy

      I found that the Berkey has slightly better filtration capabilities than the AlexaPure.

      We are talking very small differences but this is why I think that Berkey is still the better machine from a technical standpoint.

      For example, the Berkey removes lead at 99% while AlexaPure is 96.4%. And this ‘slight’ superiority is consistant across the board.

      In fact, I’ll be updating this article with a table to provide this information so thanks for bringing this to my attention.

      Stay hydrated,

  7. But Berkey gives a lifetime warranty and Alexapure only gives 1 year? the Berkey would only be $100 more for a lifetime warranty

    1. Hi Beth

      You are correct.

      This means that if lifetime warranty is important to you then the Berkey is definitely the better option even though it costs slightly more.

      Stay hydrated,

  8. Hi!
    Thank you for your research!
    I live in CA so am unable to purchase a Berkey as they will not sell them in CA due to strict legislation about frequency of testing that the Berkey does not follow.
    What is a comparable filtration system?
    Thank you!

  9. It looks like the Berkey filters out more lead than the Alexapure. Can you use Berkey filters with Alexapure and vise versa?

    1. Hi Margie

      Yes, you’re right the Berkey is sold as being able to remove lead by 99.9%

      I don’t think the Alexapure and Berkey filters are interchangeable just by looking at them – the designs are slightly different so unlikely to fit.

      Best wishes,
