Water Purification


Ultraviolet water purification is the most effective method for disinfecting bacteria from the water (aside from RO). UV rays penetrate harmful pathogens in the water and annihilate illness-causing microorganisms by attacking their DNA. 99.9% of bacteria, viruses and other pathogens…dead!


We’re not talking 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.

Going back circa 2017, we were in Florida outfitting Curiosity for her worldly voyage. We knew we wanted an inline water system that we could install and not have to fuss with.  But, we were concerned about any unit surviving the harsh marine environment.  That is when we came across Acuva.

It is a compact, all stainless steel, marine grade system we could install right at our faucet.  We were sold.  So, we requested a unit to review…and here we are over a year later, happy, hydrated sailors.

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 Eco is $649, which may or may not seem like a big investment to you, but it is way cheaper than buying bottled water.

We own the ACUVA ECO 1.5.  I know from the photo it looks like we installed the ‘ARROW’ model, but it’s because they have updated their packaging.  That said we have just installed the spanking new ECO NX model in my mom’s van and it is SWEET!  Nearly half the price of our ECO 1.5 model but just as good.  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 power by increasing pH, making small water clusters and providing beneficial minerals such as calcium, magnesium, potassium and sodium.

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

      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

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