Do you really know what is in your tap water? Yeah, me neither! I have been using the Alexapure for two years and wanted to put it to the test! Is the Alexapure really filtering? And how often do I actually need to change out the filters?

What is an Alexapure?

Alexapure is a brand of water filtration systems that promises to remove 99.9999% of impurities from your tap water, leaving you with clean, safe, and great-tasting water.

The Alexapure water filtration system is a popular choice among homeowners looking to improve the quality of their tap water, well water, and even water with known contaminants!

As a real user of the Alexapure system, I could already tell that the Alexapure improved the smell and taste of my water, but what about the contaminants? In this post, I will discuss my experience with testing* the Alexapure system with my city tap water with both new and “old” filters.

*These are just my results using at-home tests purchased through Amazon. I also have legally safe tap water, but according to the EWG’s Tap Water Data Base, there are still quite a few contaminants. That being said, I am not scared to drink our tap water and I have no experience using this product with water that is not deemed safe for drinking. Do your own research (especially if you plan to filter well water or if using known contaminated water). Stay safe, friends.

Alexapure Product Description

The Alexapure system uses Alexapure® gravity block filter with hybrid ceramic shell to filter water via gravity using two chambers. This water filter is meant for everything from everyday use with municipal water to well water, camping trips, and off-grid living.

According to My Patriot Supply, “The Alexapure Pro’s filter reduces 200+ contaminants from water while still preserving essential trace minerals. It makes your water cleaner, safer to consume, and better tasting!”

Here are the highlighted features from the Alexapure website:


  • Durable stainless steel construction
  • Easy assembly and maintenance
  • Reduces 206 contaminants commonly found in drinking water
  • Verified filtration capacity of 200 gallons
  • Water storage capacity of 2 1/4 gallons
  • Convenient stainless steel spigot for instant access to filtered water
  • 10-inch upper chamber
  • 10 1/8-inch lower chamber
  • 21 1/2-inch assembled height including top handle
  • Weighs less than 8 pounds

Alexapure Claims and Warranty

Reduces 206 contaminants commonly found in drinking water including:

  • Bacteria (> 99.9999%)
  • Chlorine (>99.9%)
  • Fluoride (>97%)
  • Pesticides (>95%)
  • Pharmaceuticals (>95%)
  • Viruses (> 99.99%)
  • Heavy metals
  • Lead

Every filter is verified to filter 200 gallons of water (Using around 2 gallons a day at my house, that’s only about 100 days!).

The manufacturer of the Alexapure Pro water filter system also provides a limited liability warranty, which covers the replacement of the product in case of any defects. However, you have to contact customer service if you have an issue after use.

According to the Alexapure website:

We offer a 30-day, no-questions-asked return policy on all unopened products. After 30 days—or for opened products—we will review your return request on a case-by-case basis. Before attempting a return, please keep in mind that performance of filters may vary due to conditions of source water, water turbidity, and seasonal water conditions.

Alexapure Design and Ease of Use

While I like the look of the Alexapure, it is not the prettiest on the market. I personally think the Berkey is prettier.

However, the housing itself is stainless steel and durable, and the filters are long-lasting. The website claims you should replace your filter when it noticeably slows down when filtering.

After two years, the housing still looks brand new and has no dents or dings despite my active and rambunctious family.

One potential negative is that it does not come with a stand. Most users will need to purchase one. I did not like the look of the one on the website, so I purchased a wood plant stand shown in the photo that fits well.

The Alexapure system is designed to be easy to install and maintain. The filters are located in a compact housing unit that can be easily accessed for replacement.

As for installing the filters, it IS super easy. However, make sure to watch the installation guide video because we had ours installed in the wrong chamber for quite a while…

Alexapure Cost and Value

I originally chose the Alexapure because it is cheaper than similar units, and you have to replace the filters less often.

Alexapure vs the Big Berkey Water Filter System

When compared to other water filters such as Berkey filters, the Alexapure Pro filters more. If you get a Berkey, you have to get several additional specific filters to filter out all of the contaminants filtered through the Alexapure system.

  • The Big Berkey is the same size capacity to the Alexapure pro (2.25gallons) and costs $367 in 2023.

The Alexapure Pro water filter system is also compliant with California Prop 65. The system has been tested by an independent laboratory and has been found to reduce the concentration of these substances to below the permissible limit. The Berkey is not independently tested (currently) and cannot be sold in California.

Testing the Alexapure Pro vs. Tap Water

I wanted to know if my filters were still working after 2.5 years of use.

  • Original System Purchased 06/24/2020 with one filter
  • Second Filter Added 04/17/2021
  • Test date: 1/18/23

Since we fill our unit about once a day with 2 gallons of water, that means a filter should last my family 100 days. We are CLEARLY over that suggested limit for both filters. I guess we will see the results! When I purchased the filters, I *think* I remember it saying more along the lines of 3 years per filter. It seems they have changed the claim to a more modest 200 gallons on the website.

My next-door neighbor purchase a new Alexapure system one month ago (December 2022). This test will compare our tap water, my system with 2 “expired” filters and a new Alexapure with one filter.

In order to conduct the test, we purchased 3 Original Watersafe Test Kits from Amazon and followed the directions. This test checks pH, hardness, chroline, copper, iron, nitrates, nitrites, lead, and bacteria. It does not test for all of the contaminants claimed to be filtered by the Alexapure.

Analyzing the Alexapure Test Results

These test results were surprising. I expected the new filter to filter better than the 2 “expired” filters. I do not know if Alexapure changed their filtration systems in 2022 vs. my original one purchased in 2020.

The point of two filters is not to filter the water better, but to filter more quickly. However, my results show that the Alexapure with two filters did indeed filter more.

According to these results, I do not feel the need to replace my filters yet. That being said, I do not know how effective it is at filtering the other contaminants not tested. Once again, the website suggests to change your filters once the filtration slows, and ours hasn’t yet.

It is clear that the Alexapure is definitely filtering out contaminants in both cases (new and old filters). The most noticeable difference is actually the smell and taste of the water. If nothing else, I much prefer the clear taste of the Alexapure water.

How often should I change my Alexapure Filter?

The frequency at which the filters need to be changed depends on several factors, including the quality of your water and the amount of water you use. If you want to stick to the guidelines set by Alexapure to be safe, then you must change it after 200 gallons.

If you go by the test results above, then you probably do not need to change the filters as often as recommended if you want to save some money (only if you know your drinking water source is safe to drink. If you are filtering really dirty water, please buy new filters).

How many Alexapure filters should I buy?

Based on the test results, two filters seem to filter better than one. The Alexapure can hold up to four filters, but I feel that may be a bit excessive. For ease of use, I think two are required. Otherwise, the water filters too slowly.

Alexapure Review Feedback From a Real User

Would I recommend the Alexapure to a friend?


In conclusion, the Alexapure Pro water filtration system is a great option for homeowners looking for a high-quality water filter system that can remove impurities such as hardness, copper, and nitrates. The system is easy to maintain and is cheaper than the Berkey. Based on the test results, you can probably get away with using your filter longer than the recommended 200 gallons if you have a clean water source. The taste and smell of water filtered through the Alexapure is far superior to tap water.

  1. I love water purifiers. We use a different brand but have to change out our filters and, subsequently, our entire system fairly often. Trying a new system might be worth it as we definitely notice the difference between filtered and tap water, coming from a guy who is regularly dehydrated because of my animosity towards water.

  2. I’ve been wanting to get a water filter, but they seem so pricey! This is making me want to take the plunge anyways. Thanks for the analysis 🙂

  3. Great article! However one major flaw in your analysis is that the filters last about 5000 gallons before recommended replacement not 200-300 each filter should last about 2-3 years depending on the usage.

      1. “Verified” filtration capacity, just means that they stopped the testing at 200 gallons, and it still does what it claims to do. The time it would take, and the cost would be astronomical , if they continued testing it through the full 5000 gallons.

      2. When I purchased mine many years ago, they did say each filter was rated for 5000 gallons. When did they change that? I purchased (4) and they told me it would be good for 20K gallons. What a disappointment.

        1. I’m not sure! it said the same thing when I initially purchased. I have no affiliation to the company. I am hoping that it is *actually* still the same but maybe they cannot market it as such.

  4. We are checking out all water purification types to get one for our family. My friend showed me her Berkey. She has the two tall filters but also has round arsenic filters. Is that something only Berkey has or does the Patriot brand filter arsenic a different way?

  5. Thank you for this very thorough experiment. It helped me to feel reassured. I have an Alexapure Water System with 3 filters inside. Mine are going on 3 years and 2 years old. I don’t taste any difference now at all, but I was starting to wonder if they are working as well, since they are most likely over due to change according to the recommendations. After reading your article I feel a lot better and, in fact, I’m 💯 sure they are working. After reading your article, I took a glass of tap water and a glass of filtered water and tried to see, smell and taste the difference. I could see, smell and taste the differences easily. The filtered water tastes great, looks crystal clear and doesn’t smell like chlorine. I will save my money and not worry about changing them until I start smelling or tasting a difference.
    Thank you again!

  6. I have used mine for almost 2 years. Ive washed it out but have not changed filters. Someone from the company told me just wait until it starts pouring slowly out of the faucet. So far its the same as brand new, so I’m going to wait.
    Where do you get something to test the water?

    1. Hi Cindy! I totally agree! Mine seemed to stay good forever! I got the kits off Amazon. I have a link in the post or you can search Water Testing Kit and you should find some options 🙂
