Blu Tech Water Filters:

SUPERIOR FILTRATION: The Blu Tech MR3 is a 3-stage RV/Campground water filter system with the 0.2 MICRON High Flow Filter*, the Sediment “LONGEVITY” Filter, and the Granular Activated Carbon Coconut Shell “TASTY” Filter. Smaller micron size means greater filtration! Standard RV inline water filters measure in at 20 Micron. Blu Technology 0.2 MICRON Filters provide filtration for particles that are up to 100x smaller!

DESIGNED FOR RVs: The MR3’s 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! Get 3-4** months of clean and clear water before changing your filters, thanks to the Sediment “LONGEVITY” Filter!

TRUSTED BY RV MANUFACTURERS: The Blu Technology 0.2 MICRON Filter is trusted in the industry and comes standard on RVs from some of the biggest manufacturers, it is also approved by the RVIA. The 0.2 MICRON High Flow Filter is manufactured with FDA-approved materials!

GREAT TASTE: 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, hydrogen sulfide, and more!

DURABLE AND LIGHTWEIGHT: 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!

COMPACT DESIGN: Our 5-inch filters allow the system to be significantly smaller than conventional systems with 10-inch filters, allowing the MR3 to fit in your RV’s wet bay. The MR3 weighs just over 11 lbs, whereas similar 3-Stage filtration systems on the market weigh up to 28 lbs!

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!

    Filters work great.

    I ordered 4 new packs to have in stock. I have not used the new ones yet, but these exact same filters have worked great in the past.

    Great filters

    Blue one must be the off grid model. Was in my original set but I ordered that standard replacement set and had a white filter. Seem to work well although getting the canisters off was a bit of a challenge and took some time. Is there an easier way other than by hand to remove those?
