Safe Water!? Acuva Eco NX-Silver Water Purification Upgrade!

Safe Water!? Acuva Eco NX-Silver Water Purification Upgrade!

One of the most common questions we get is how do we safely drink from our RV’s fresh water tank. Some RVers avoid the question by using bottled water, but we’re big proponents of avoiding the cost, hassle, and waste of doing that. And besides, isn’t it an awful shame to have a vehicle with a large fresh water supply and not even use it as the source of your safe RV drinking water?

Making sure the water onboard your RV is safe to drink usually involves chemicals (typically chlorine) to sanitize the fresh water holding tank. But for the past several years, we’ve been using an Acuva Eco UV-LED water purification system at our kitchen sink.

We haven’t sanitized our fresh water system in over two years, but our Eco has allowed us to safely drink directly from the tank the entire time. Now that we’ve upgraded to the latest Eco NX-Silver, we’ve got a higher flow rate, at a lower price, with the peace of mind of NSF/ANSI certification.

Laboratory Testing

Before installing our Acuva, we would typically sanitize our fresh water tank about every 6-12 months… which took time AND used quite a bit of water. Since installing the Acuva, we’ve gotten quite lax… and realized it’s been over 2 years since we last sanitized. And nobody’s gotten sick yet! (NOTE: this isn’t something we recommend doing, we’re just reporting that we’ve missed sanitizing for a long time and have stayed safe thanks to our Acuva providing clean drinking water)

Since some people are sensitive to even small amounts of chlorine, not adding any into the fresh water system can be an additional benefit.

The new Eco NX-Silver offers several improvements:

  1. It has a higher flow rate. Not that our original Eco was bad (about 0.9 liters/minute), but being able to fill your glass faster (now 1.2 liters/min) is a bonus.
  2. The Eco NX-Silver is flow-triggered, instead of faucet-triggered. With the old Eco, you HAD to use Acuva’s Smart Faucet… because the faucet itself contained the on/off switch that activated the UV-LEDs. With the new NX-Silver, it’s triggered by the water beginning to flow… which means you can now use the system with ANY countertop faucet.
  3. The flow trigger brings another way to save money… you can buy the NX-Silver WITHOUT the Smart Faucet. If you already have a separate water dispenser at your kitchen sink, you can use it with the Eco NX. The only feature you’ll lose out on is the blue LED indicator light built into the Smart Faucet… which is a cool visual, but not required.
  4. Another advantage of the unit being activated by flow is that it can supply purified water to multiple locations. If your floorplan allows it, you can plumb a single Eco NX-Silver to your kitchen faucet, refrigerator (for the ice maker and/or through-the-door water dispenser), and/or a stand-alone ice maker. Just be aware that the system won’t dispense water faster than 1.2L/min… but since those items aren’t likely to be running all at the same time, you should be OK with a single Eco NX supplying them all. Whenever one of them starts the flow of water, the Acuva will activate automatically.
  5. This new model has passed rigorous testing and meets NSF/ANSI 55 Class ‘B’ (for the supplemental bacterial treatment of disinfected public drinking water) and NSF/ANSI 372 (for the determination and verification of product compliance to minimize lead contaminants) standards.

Can this Eco be attached to the existing kitchen faucet so there is only one facuet ont he counter?


Sunday 21st of March 2021

Hi Angie. Technically, yes. But the flow rate might be too low for other tasks you’d want to do at the kitchen sink (washing dishes, filling pots, etc). So consider that... and maybe look at one of the higher flow-rate units like the Arrow. Would probably be a more pleasant experience long term.

Curious about winterizing the acuva silver water purification system


Friday 12th of February 2021

Hi Wayne! Before winterizing, you should remove the inline pre-filter, just as you would with any under-counter water dispenser, and either bypass it (if your rig is plumbed to allow that) or use a piece of tubing in the filter's place (some RVs come with that section of tubing for just that purpose). If you're blowing air through the lines, you can blow air right through the Acuva, just like the rest of the plumbing system. If you're pumping anti-freeze into the system, disconnect and drain the Eco, as Acuva recommends not putting anti-freeze into it. Just be sure to drain the line going to the Eco so it doesn't freeze.

We love our new Acuva Eco NX-Silver water filter! It has been installed for about a month now and has worked flawlessly. The Acuva is so easy to use, has a small form factor, and is very esthetically pleasing. Your review and installation videos made the decision and installation straightforward. Our water has no taste regardless of where we fill our tanks and the flow rate is just perfect. In addition, it was very securely packaged and the drawstring pouch around the fixture was a nice touch. Traveling through Glacier, Yellowstone, and now the Grand Tetons we have consumed quite a bit of water hiking, kayaking, and biking and it always tastes good. Your reviews, installation videos, and discounts on products is like having our own concierge buying service. Keep up the great work, stay safe, and hope you will be able to winter in a warmer climate.

Thank you so much for the kind words, Larry! To say you just made our day would be a big understatement. It’s always great to hear that we’ve been helpful, and your comment means so much to us. Thanks very much for taking the time.

When you put out the first video about the Acuva system I went out and got the slightly larger unit that came with flow-activation as I wanted for my ice maker as well. It is the single best aftermarket item I have installed in our coach. Thank you again for doing that first video.

If you can run a line to your fridge/icemaker you will be forever happy that you did.

Take care, John

Having an Arrow on an RV is big time! That's the model that Nikki & Jason have in their catamaran. So glad to hear you've been enjoying the upgrade, John!

By the way... we just cracked open that awesome port you so kindly gave us. Thanks again!

Thank you for your wonderful videos and specific information. So often your insight has helped us resolve issues and improve our coach. We just used your discount code to buy the ACUVA system. Looking forward to no more bottled water runs! Safe and Healthy Travels to you!

That’s awesome, Sue! Thanks so much for the nice comment. We hope you love being free of bottles as much as we do. ????
