Water Purification


Ultraviolet water purification is the most effective method for disinfecting bacteria from the water (aside from RO).


We’re not talking about the old UV lights that were made with mercury, were power-hungry and needed replacing every year.  There is a new generation of LED-UV and it’s a massive improvement!  As with other LED lights, the LED-UV lights are much more environmentally friendly and last way, way, way longer (around 10 years).
Going back circa 2017, when we were outfitting Curiosity for her worldly voyage, we knew we wanted an inline water system that we could install and not have to fuss with.  Which is how we ended up with the Acuva.

It’s a compact, all stainless steel, marine-grade system we could install right at our faucet.

UV-LED Water Purifier

  • Sterilizes 99.9% of bacteria, viruses and other pathogens
  • Improves taste, odor and color
  • Chemical free water purification
  • Functions like a regular faucet
  • Compact design, ideal for small spaces (boats, RV’s, tiny home)
  • Low power consumption
  • Environmentally friendly
  • Hooks up to a standard 12V battery or AC power


Doing the math

The average human should consume 2 liters of water per day?  That is just the bare minimum because in the tropical heat we consume way more.  For example, in Tahiti a 5 liter jug of water is 330CFP.

  • 2 liters a day per person x 365 days in a year = 730 liters
  • That means we would need 146 of those 5 liter jugs.
  • 146  5-liter jugs x 330 CFP Franc = 48,180
  • 1 CFP Franc = 0.0095 USD
  • 48,180 CFP = $457.72 USD
  • $457.72 A Year Per Person x two = $915.44

$915.44 a year just in drinking water!  The Acuva may or may not seem like a big investment to you, but it is way cheaper than buying bottled water.

$100 Discount

Acuva has offered up $100.00 OFF any system, just use the Promo Code WYNNS at checkout!


We have the ACUVA ECO 1.5 installed on Curiosity.   BUT, we just installed the spanking new ECO NX model in my mom’s van and it is SWEET!  More affordable and all the same benefits.  If you’re looking for a new water purification system we’d recommend you go for the new ECO-NX.

Extra Filters

Finding the correct filters through sites like Amazon is a deep search!  There are so many models that all look and seem the same…but they are NOT!  To get the ¼” female thread you must search the EXACT filter name and confirm the MFR Model # after you click the link.  For my fellow Amazon shoppers, here are our exact models and links:

Basic Carbon Filter  – 

Pentek GS-10-B Inline Water Filter (Model 255503-43)

Granular activated carbon filter that reduces bad taste and odor including chlorine (uses coconut shell granular activated carbon to reduce the bad taste and odor of chlorine plus common particulates and other impurities).

Re-Mineralize Filter:

iSpring 10″ Inline Minerals Filter FX15

By adding this inline filter as the final stage in an RO system, you’ll get the optimum benefit of the alkaline-mineral media. With this addition, you turn your existing reverse osmosis system into a spring water source with all alkaline and antioxidant qualities. This alkaline antioxidant filter provides abundant active hydrogen. It also increases the reduction of power by increasing pH, making small water clusters and providing beneficial minerals such as calcium, magnesium, potassium and sodium.

    Trying to order the NX version from Canada. The discount code provided doesn’t actually work.

      Oh no! I will send an email to our contact now and see if I can get a response quickly for you. Stay tuned!

    Maybe Mary could add the Some form of recirculate should have been part of the design with a tankless heater in an RV.

    Hi, lots of comments relating to:



    I really feel for Mary and her (previous) Airstream water issues. I’m so glad you knew all the right solutions for the TASTE issue to help your Mom / MIL! The odd thing is, I have had / have the same issues, but I’m in a house! Our house is on a well. The house came with a water softener, but the water was tasted HORRIBLE! We had a Kinetico system installed, which provided for R/O & UV, but only at the kitchen sink new water tap, and the refrigerator for ice & water. I told the Kinetico folks I wanted this water at the bathroom sinks and showers. They then told me how much over the already over $6k that would be. We’d have to buy individual systems for each bathroom sink, but the showers would be too much. Ugh! So, our teeth brushing water still tastes horrible. When we remodel our bathrooms before downsizing from our already small ranch home, we plan on installing the system you got for Mary to make the bathroom sink water So. Much. Better. Thank you so much for the great info!


    However, what really makes me mad for Mary in her house-priced Airstream RV is the hot water for a shower issue. We, too, have a tankless hot water heater. There has to be enough draw for hot water to come out of the tap. So, unless maybe the dishwasher is running, as we RARELY wash clothes in hot water, the water just to wash our hands is always cold! And, as with Mary’s issue, we have many, many gallons of cold water going down the drain until the water heats up enough for a shower. For us, we have a well. One definitely can run out of water on a well, but Mary’s supply is much more limited. For the price she paid for a brand new RV, all I can think is, what on earth is wrong with those people who designed that water heater system?! There MUST be a way to heat the water before turning on the tap, that allows for not wasting water. I also disliked hearing that for the folks who prefer to wet down, suds up, then rinse, with the water being turned off during sudsing, the water heating process starts all over again. Unreal! I’d be very interested if you find a solution to the shower’s water heating issues.


    I’m wondering if you or Mary have come up w/ a solution to the cabinets opening during transit issue? What about magnetic baby locks? They’re normally screwed into a cabinet, but you could test with a double back sticky tape, then use a super serious glue to hold in place permanently.


    For the tall, pull out storage shelf, I’d line it something that could bend to come up the sides of the basket, and maybe install a thin wall on the side that is accessed less frequently. That will keep small things from falling through the shelves, and taller bottles that are prone to tipping over could be strapped up against the thin wall.


    For the couch end where that removable pillow falls off, what about installing a more hardcore type of Velcro?

    Hello guys!!!
    Is this easy to install or do I need a plumber to do it?

  5. Lyn

    hi. how long does each filter last? ie.. how many spares should we oder at a time?
    thanks x

    • Curious Minion

      They are rated for filtering “x” gallons of water. If you follow the link in the post the product info will tell you how many gallons they will filter before you need to replace them. How many gallons you use will depend on how many people you have onboard. Is it just you? Or are you a family of 5? You need to estimate your usage. In general I think having one spare would give you time to reorder IF you are doing something like coastal cruising in the U.S. But if you’re sailing around the world then you would need to take more.

    So I’m looking to order the system, only I notice the eco version you have at $649 isn’t the one in your pic. What is the one you have 1.5 or 5 litre. Thanks

  7. Sharon Bradley

    Thanks for all the water information. Do you have any information on the remineralization component of water process? Thanks, Sharon
