A New Multi-Stage Design
brings specialized filtration media together in one filter for broad-spectrum performance.
2X Faster Flow
Get filtered water faster, without changing the gravity-powered simplicity of Alexapure Pro.
Testing That Goes Beyond the Tap
Expanded testing reflects both everyday water concerns and the uncertain freshwater sources** you may need to rely on during emergencies.
The new Alexapure Pro filter works with both generations of the system. It connects directly to the new Alexapure Pro and includes the adapter needed for original systems—so every Alexapure Pro owner can take advantage of the newest filter technology.
From lead and arsenic to fluoride, nitrates, uranium and more.
Dedicated testing for pesticides, herbicides, glyphosate, VOCs and SVOCs.
Expanded testing includes microplastics, PFAS (forever chemicals), pharmaceuticals, BPA, DEET and other emerging compounds.
Bacteria, cyst-sized microspheres, turbidity and particulates put the filter to the test against concerns that become especially important when relying on uncertain freshwater sources.**
Alexapure Pro has been helping families filter their everyday drinking water and prepare for uncertain water supplies for more than a decade. This next generation builds on a name people already know and trust.

"Not only is the color different on these filters but so is the screw in area. They replaced the Alexapure filters I had in my Big Berkey which fit and worked perfectly. These new oneshave a weird adaptor on them that has the filter sit above the water in the bottom of the top portion so there is about a half inch or an inch of water that sits in your top tank."
"Not only did our filters come fast , the team is so responsive , polite and helpful . I am really impressed with the friendly people at MPS. Thank you The Blankenship’s"
"The filters are working fine. The instructions didn’t say to flush the fisrt fill therefore it had a salty taste to it. I think it needs to have a least one flush and maybe two. This is my opinion."
"We have used the Aquapure system for several years now, and notice a huge difference in the taste of water not filtered through the system. Reading the long list of particles eliminated or greatly reduced by these filters, it is the choice we make for our family's health to purchase and use this system. Patriot Supply has the number one customer service department - no one calls to double check an order was received or if I am pleased with the purchase - no one but Patriot Supply. Excellent!"
"I ordered these last year. When I went to open them recently, there was an issue. I contacted patriot supply, they got the lot # of the faulty filters to report. The immediately sent me four new filters. I was so blessed to have such prompt help, and the new set of filters I received are working beautifully with no issue."
"I had to order the new filter and it’s terrible. My water taste just like my tap water. It is not up to the standards of what I expected since my first water filters were way better"
"These filters are USA made and the best for our water issues. I made the mistake of trying something cheaper...ha. The water tasting like pond scum. Always trust My Patriot Supply!"
"You guys are great. Thank you SO much for working with me when my package was delivered to the wrong location and never able to be recovered. I truly appreciate it. I will continue to confidently place orders with you and recommend you to others."
"Great and reliable water filter system. Excellent customer service and fast shipping! Repeat customer here for years."
"i have not used yet, Are part of my long term prepping,"
Each Alexapure Pro filter is rated for up to 200 gallons of filtration*, depending on the quality of the water you’re filtering. You don’t have to keep track of every gallon—when you notice a significant decrease in flow rate, that’s a good indication it’s time for a replacement.
The Alexapure Pro can hold up to four filters at once—and every filter you add gives you two benefits: faster flow and more filtration capacity.
Two filters provide approximately twice the flow rate and up to 400 gallons of combined filtration capacity. Install four, and you can get approximately four times the flow rate and up to 800 gallons of combined capacity before replacement.
That means less time waiting for filtered water and longer between filter changes, giving you more filtration capacity already in place when clean water matters most.
Yes. The new Alexapure Pro filters are fully compatible with original Alexapure Pro systems. Each new filter includes a simple quick-connect adapter so you can use the newest filter without having to replace the system you already own.
The new Alexapure Pro filter was reengineered from the inside out. It delivers 2X faster flow, features an expanded testing program built around both everyday and emergency water concerns, and is now made in-house in the USA for greater control over quality and consistency.
It’s also fully compatible with both new and original Alexapure Pro systems.
No. The new Alexapure Pro filter arrives ready to use with no priming or flushing required. Simply install the filter according to the instructions, fill the upper chamber and let gravity do the rest.
Not when properly stored. Unused filters can be stored indefinitely in their original sealed mylar packaging. Keep them in a cool, dry place away from sunlight, humidity and chemicals such as cleaning supplies, paints or gasoline.
Since the filters no longer need to be pre-primed, you don't have to worry about freezing and cracking during storage. So your backups are always ready when you need them most.
No. Unlike Reverse Osmosis, distillation, or deionization systems, Alexapure Pro is designed to target unwanted contaminants without stripping your water of its naturally occurring dissolved minerals. In-house testing showed that overall dissolved mineral levels remained consistent before and after filtration.
Alexapure Pro is designed for simple upkeep. Clean the stainless steel chambers periodically with fresh water, mild soap and a soft cloth. If you notice buildup on the filter or a decrease in flow, remove the filter and gently clean the exterior under running water—never use soap or detergent on the filter.
After cleaning, reassemble the system and make sure all connections are secure before refilling. With routine care, your Alexapure Pro is ready to keep filtering whenever you need it.
*Performance and capacity are based on controlled laboratory testing. Actual results may vary depending on water quality, target contaminant and usage.
**Do not use with water that is known or suspected to be microbiologically unsafe or of unknown quality without adequate testing and/or disinfection before or after the system.
It is essential to follow operational, maintenance, and filter replacement requirements as directed for each application for this filter and system to perform correctly. Read the information accompanying the system and change the filter as suggested. The contaminants or other substances removed or reduced by this water filter are not necessarily in all users’ water.
