The Biggest Problems with AlexaPure Pro
The AlexaPure Pro is a cost-effective way to get filtered water in your home but here are some of the biggest problems that not enough people talk about:
This is a countertop water filter and as such you will need a sufficient amount of countertop space to accommodate this device.
You will need to manually fill it with water, which can be quite cumbersome.
AlexaPure pro is good at treating everyday tap water but not ideal for water, which has more serious issues e.g. well water.

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.
AlexaPure Benefits In Detail
Before comparing AlexaPure to its biggest competitor the Berkey. Let’s look at this product as a stand alone and consider all the AlexaPure pros.
By far the biggest benefit are its filtration capacities.
AlexaPure filters water through a dense carbon block filter that also uses a hybrid ceramic.
The result of this is that it can remove around 99.99% of all sorts of contaminants. This includes disinfectants, pathogens, bacteria, cysts, heavy metals and even some radioactive elements.
1. Easy to install and easy to use.
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.
2. Affordable
AlexaPure is usually a little cheaper than is counterparts. This includes the prices for its replacement filters. Keep an eye on places like eBay and Amazon for on-going sales and special offers. Because it doesn’t use electricity, it will not increase your operating costs or energy bills.
3. Good looking.
It’s pretty aesthetically pleasing to the eye. This makes it something that will fit into the decor of most homes.
It’s made of high quality stainless steel so has a premium finish and this leaves you with a high quality appearance that will attract everyone’s attention.
4. Certified water removal.
Like many other high level water filter systems, the AlexaPure has a number of independent water quality tests.
All tests and certifications show its ability to deal with all sorts of contaminants and bacteria. This includes the elimination of protozoa, hormones and viruses.
5. Large capacity yet very small footprint.
The AlexaPure has a storage capacity of clean filtered water that is 2.25 gallons. While it is also capable of dealing with up to 1.5 liters of water at a time.
6. Lightweight.
It is actually very surprising to see how light an empty AquaPure is, despite how big and heavy it looks. The entire unit (including the ceramic filter) only weighs around 6.5 kg. This makes it super portable and ideal for outdoor events.
AlexaPure vs Berkey Water Filter
Anyone thinking about buying an AlexaPure has probably considered buying a Berkey first. Let’s compare the two:
AlexaPure Water Filter | Berkey Water Filter |
 |  |
| 5000 Gallons (Filter Max Lifespan). | 6000 Gallons (Filter Max Lifespan). |
| 2.25 Gallons | 2.25 Gallons |
| Lead removal >96.4% | Lead removal >99.9% |
| Chlorine removal >99.9% | Chlorine removal >99.9% |
| Chloroform removal >99.9% | Chloroform removal >99.8% |
| Copper removal >99.0% | Copper removal >99.9% |
| Chromium VI removal >98.7% | Chromium VI removal >99.8% |
| Fluoride by 99.9% | Fluoride by 99.9% |

Why AlexaPure Might Be Better?
The Alexa Pure water filter system is effective, lightweight and costs less than a Berkey.
The lower price at a similar filter capacity makes the AquaPure more accessible (at least cost wise) to the average person.
It’s a quality product that also provides good customer service according to verified customer reviews.
Why The Berkey 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.
Where To Buy The AlexaPure Pro
The best place to buy the AlexaPure Pro is from an online store like eBay or Amazon.
Amazon might be a better choice because you get to read all the verified customer reviews before you buy. It’s also great to get your AlexaPure direct from Amazon.co.uk.

AlexaPure Pro WORTH it?
The short answer is yes.
But it’s not as effective as the Big Berkey counter top filter system.
However, 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.
The 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.
So an even more cost-effective water filter is the AquaTru. See the video above to get an idea of what it can do.
Do you know of any testing of the AquaPure filters at the 5,000 gallon mark or even 3,000 or 1,000? Are there any charts that show the average decline in effectiveness over time? Are there any home tests, like Berkey’s Red Dye test, that will indicate continued effectiveness?
Hello! Can I use Berkey filters in the Alexapure Dispenser? I live in CA and Berkey won’t ship dispensers to me. Thx in advance!
Hi, I purchased the Alexapure in 2020 and I am extremely happy with it. Our tap water tastes horrible and bottled water doesn’t taste much better. So, I purchased the Alexapure and extra filters. The water tastes great and Alexapure has more than paid for itself in less than two years.
I highly recommend it.
Luke, my question is, does it hurt the filter if you have a Salt water Softner for your harm.
Hi Luke!
Firstly – thank you SO much for this site. A great help in making a decision. I’m leaning toward the Berkey, a friend has one and I’m very impressed at the “clean” taste of the water overall. However – my concerns are that they don’t provide a data sheet, so how do we “know” it does as they claim? Also, does the Berkey remove Glyphosate?
Thanks, Jacqueline
Hi Jacqueline
I just found a reliable Berkey contaminants list and the article has been updated to reflect this.
To answer your question yes, Berkey removes Glyphosate down to below lab detectable limits.
>Berkey Contaminants List< Stay hydrated, Luke P.s thank you so much for the information linking to the Canadian Berkey lab test results.
I’ve been drinking and cooking with distilled water for many years. I decided to purchase the Alexapure on top of what I was already doing to be sure I was using clean water. I filter the water with Alexapure and then distill that water that just got filtered. I was astonished that my distiller had a lot more residue at the bottom when I started using the Alexapure filtered water than when I was simply using tap water. Something doesn’t add up.
What is meant by your suggestion to “change filters regularly” on the AlexaPure system. If each filter filters 5,000 gallons, what is a “regular” schedule for changing filter?
When you say the Berkey filters 99.9% of lead. That means with the extra lead and chlorine filters correct? How much does it filter without the extra filters? Same question for the chlorine please.
Hi Kat
It is my understanding that you only need the special filters for extra fluoride and arsenic protection. Everything else (like lead and chlorine) should be covered by the regular Berkey filter cartridges.
Stay hydrated,
Luke
Thank you for clarifying for me.
The Berkey system does NOT filter flouride. It is a scam product. I have yet to be convinced of the lLexapure.
Hi Nina
The Berkey DOES filter fluoride when you get the fluoride and arsenic filters.
Stay hydrated,
Luke
That’s the issue having to buy extra filters when the alexapure can filter these two without the extra cost. Alexapure wins hands down.
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.
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.
I saw someone say that the Berkey fluoride filter is aluminum. Would that leach into the water?
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.

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.
Hi Marion
Alexapure might be affected by the same California laws that affect Berkey? Perhaps you might want to consider something like AquaTru?
I’ve written an AquaTru review article here with a Berkey comparison.
Stay hydrated,
Luke
I live in california and alexapure can be shipped here. I have one of their units and I also purchased 4 additional filters and created my own 5 gallon bucket water filtration system for more water availability.
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%.
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.
Does this remove chloramines so you can use the water for fish or house plants, etc?
Hi Daniel
Both Alexapure Pro and Berkey remove chloramines by 99.99%

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!
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,
Luke
Hi Wendy,
Berkey suggests removing the filters from the tank if you’re away longer than a few days. They suggest removing and storing them in ziploc bags in the refrigerator and then re-priming them before re-installing in the Berkey. Not sure how long they can be safely stored this way though.
Your best bet is to carry your filter with you. That will ensure that the water is fresh and the filters remain moist. Remove the filters and lay them on the bottom of the tank to prevent snapping them off at the base. Besides, you want to filter your water at home also don’t you?
Does either brand remove chlorinated hydrocarbons? And if so, what is % removal?
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.
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,
Luke
But Berkey gives a lifetime warranty and Alexapure only gives 1 year? the Berkey would only be $100 more for a lifetime warranty
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,
Luke
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!
Talya
Hi Tayla
Hmm I would try the keywords “Stainless Steel Gravity Water Filter” into Amazon and pick the one with the best customer reviews. E.g. I currently see one called RainFresh SM4A that looks pretty decent.
Stay hydrated,
Luke
It looks like the Berkey filters out more lead than the Alexapure. Can you use Berkey filters with Alexapure and vise versa?
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,
Luke
Does Alexapure filter out glyphosate?
Hi Steven
Yes the Alexapure filters glyphosate by 99% according to the manufacturers’ literature.
Best wishes,
Luke
