The Blu Tech MR3 is a self-contained in-line water filtration system designed to connect between public or private water supplies and your RV, Vessel, or VAN providing exceptional high flow benefits while filtering contaminants, viruses, and pathogens that other filters can't. The expert team of water specialists at Blu developed a 5 inch water filtration system that filters more effectively than traditional 10 inch filtration systems, providing higher flow rates while utilizing new 0.2 micron filtration technology resulting in the most compact, efficient and travel friendly filtration system on the market today. 

The 3 stage water system provides pre-filtering for sediment, sand and other large particulates bringing longevity to your system's filter life. The stage two high flow 0.2 Micron Filter uses a proprietary, patented, electroabsorption media technology capable of removing submicron pathogens and inorganic contaminants through electroadhesion and ion exchange. The 0.2 micron electro-adsorptive media is a breakthrough in water filtration technology, allowing the filtration of lead, bacteria, volatile organic compounds (VOCs), microorganisms, and more, all while maintaining a high flow rate and ultra-compact filter medium not previously possible with traditional filter technology.  The third stage "Tasty" filter utilizes premium coconut and carbon filtration to remove small amounts of chlorine and other contaminants that contribute to water and taste problems.


Built for Longevity & Portability

The MR3 is a fully stainless steel water filtration system, including the frame, canisters, and quick connects. The stainless steel build makes the system both durable and portable. The Blu Tech MR3 is corrosion-resistant and able to withstand the elements in rain or shine! Stainless steel filter housing is more durable than plastic and ensures light is kept out to prevent bacterial or algae growth. The included quick-connect system utilizes stainless steel; high-quality quick connects that are drinking water safe and fully compatible with the full line of quick-connect accessories available. 

Out-of-the-box Ready. 

Arrives with all filters pre-installed. Includes compact aluminum filter frame, filter housings, and all associated connections pre-installed. Includes quick connect inlet and outlet with standard garden hose attachment fittings. Additional information is located on the Documentation Tab.

Trusted Filtration in 3 Stages

The first stage is a longevity filter. This takes out all the big particles first, which keep them from clogging up the next filter and extending the life of all the filter cartridges. 

The second filter is the patented 0.2 micron filter. The smaller micron size means greater protection - similar systems use less effective filters that are 1 micron or larger. This filter is focused on safety of the water to create clean drinking water.  

The third and last filter is all about taste and smell. This filter uses activated carbon and coconut shell to improve your water's taste and smell factor. It has also been shown to remove small amounts of chlorine if present in the water.

Extend Filter Life with the "Longevity" Filter

Extend the life of your filters with the additional Sediment "LONGEVITY" Filter. With this added pre-filter, you will get 3-4 months of clean and clear water (depending on the turbidity of the water). Blu Technology water filters are designed with high flow technology, allowing them to have a high flow rate despite their high filtration rate! The Blu Technology "Off-Grid" filter is made in the USA.

Get Better Tasting Water with the "Tasty" Filter

The Granular Activated Carbon Coconut Shell “TASTY” Filter works to improve the taste and the smell of your water. The “TASTY” Filter works to address common taste and smell concerns with water at campgrounds by addressing chlorine and more!

Effectively Removes

  • Chlorine
  • Cloudiness
  • Bad taste and odors
  • Organic chemicals
Filter Out Dangerous Particles with the 0.2 Micron Filter

Blu Technology’s “Off-Grid” Filters are highly efficient for 0.2 Micron-sized particles. Standard RV inline water filters measure in at 20 Micron, so Blu Technology's “Off-Grid” Filters provide filtration for particles that are up to 100x smaller! The “Off-Grid” 5-inch filter is designed with an added layer of protection only offered by Blu Technology, and is  one-of-a-kind in the industry. The Blu Technology “Off-Grid” filter has an additional electro-adsorptive media technology that is able to capture even more submicron contaminants through ion exchange! 

Effectively Removes

  • Lead
  • Mercury
  • Iron
  • Volatile Organic Compounds (VOCs)
  • Arsenic
  • Giardia
  • Cryptosporidium
  • E. Coli
  • Cysts
  • Legionella Viruses
Thread Into Water Sources Easily with Quick Connects

The stainless steel garden hose quick connects allow you to thread into city water or well water at any campground. Connect/disconnect quickly and easily – get 1,000+ gallons a day with a high flow rate!

Compact Design

Our 5-inch filters allow the system to be significantly smaller than conventional systems with 10-inch filters.

    Great Quality. Amazing Customer Service. Awesome filtration. Enough said!

    Love this!!! Amazing filtration! Reliable plus very convenient and fits in my RV! Love it! Best on the market. Highly recommend especially after a shipping issue needing my address changed and they called the shipper to change and it arrived safely the day it was supposed to. My husband raves about the quality and its design also. So all around good deal! Oh and I've heard they're vet owned? But couldn't confirm that, regardless this is from the US, which we appreciate. :)

    Don’t spend the money

    I spent a lot of money on this filtration system, hoping that it would clean up the water. It did not I would not recommend this. It is way too much money and in my opinion does not work. I am very disappointed with the results and I do not feel the water is safe enough to drink, I would not recommend anyone spending the money on this

    Filters didn’t help our situation much.

    I’d like to start off by saying the water is really bad where we are staying. I thought the filter system would make the water drinkable. I guess it got better for a couple of days, but I think the filters would have to be changed every 2 weeks to make our water drinkable. I was expecting a better result.

    Easy set up. Easy to use.

    Having the quick connect for both ends of the hose makes this system easy

    Portable and useful water filtration

    I am quite impressed with the design of this portable water filtration system. One suggestion that might be a feature request, utilizing some sort of drain plug system on the bottom of each cylinder. We will be using our system on and off throughout the year. It is quite simple to detach each filter cylinder, to dry them out for longer term storage, but wanted to see if a drain plug could be useful. Overall quite satisfied with this product and will definitely be sending other RVers your way!

    Almost perfect

    Would have been better if the quick connects installed were reversed.
