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.

    Almost perfect

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

    Very pleased

    We have had this unit installed now for a few months and are enjoying the clean filtered water and the convenience of the system. The hubby is not very handy but was able to install everything with no problems and it’s all tucked away underneath in our wet bay so we don’t have to take up valuable room in our living space/counters with other water filtration systems. We are very satisfied!

    I am a happy camper!

    I am a full-time RV-er. I winter in Southwest Arizona. The city water is very hard here. I tested my water with water test strips and it showed extreme hard water that was over 500 ppm. I was shocked. So I thought I would invest in the blue tech system and water softener. I gave the system some time and then tested the water in a few days and I was happy to report that the water was in the excellent zone of the test strips and now I have soft water. I am very satisfied with the blue tech system

    Blu Tech MR3

    Sturdy, well made and lightweight. I have a lot more confidence in the water we are using. The .02 micron filter sealed the deal for me. I really like the stainless steel and the quick connects that came with the unit.
