Beneficial Minerals Added

The Pelican Pro RO 2-stage post filter offers a carbon/mineral filter inside that adds back in the essential minerals (calcium & magnesium) to your drinking and cooking water which are removed from RO systems and Ultra filtration systems.

How Does It Work?

Pelican’s 6 stage filtration system is both effective and compact, so it will fit below your sink and provide water that is better than bottled water. Food you cook, coffee you make, and liquids you drink will taste better. Here’s how it works.

  • Sediment

    Reverse Osmosis removes dissolved solids, chemicals, and contaminants.

  • Pre-Filter

    RO creates pressure and forces your water through a semi-permeable membrane.

  • Filter

    By filtering out impurities, you can enjoy clean-tasting and delicious water.

  • Membrane

    Sediments and contaminants collected in the filters are safely flushed down the drain.

  • Polishing

    Pelican’s Pro RO delivers great tasting water straight out of your kitchen sink.

  • Minerals

    Essential minerals are added back into the water.

How Is Pelican Different?

There are many RO water filtration systems on the market, and they can vary in quality substantially. Consider these factors when choosing a system:

Number of Filters

Systems with more filters and membranes can remove more impurities from the water.

Reverse osmosis systems typically use 5-stage filtration. The Pelican Pro RO adds a unique 6th stage to remineralize the water.

Amount of Water That
Can Be Filtered

The membrane of the Pelican Water Pro RO system can filter 50 gallons per day, which quickly refills the storage tank.

Our filter delivers 30% more flow from the faucet than a traditional RO system.

Minimal Maintenance Required

No tools are needed to maintain our RO system - just remove one cover and replace the cartridge.

Change the 2-stage post-filter every 6 months and your 4-stage membrane every 18 months.

Sign up for Watershield Autoship Club and get your replacement filters for your RO shipped to you without the hassel of having to remember them.

Green By Design

Wastes 50% less water than standard RO systems.

Smaller and more compact means less resources used to manufacturer.

Smaller packaging and light shipping reduces environmental impact.

Made in The US

High quality membranes and system made in the USA.


The Pelican Water Pro RO system is smaller and lighter than other filtration systems, and can be easily installed in a small kitchen cabinet.

Reviews By Bazzarvoice
Pelican Pro 6-Stage Reverse Osmosis (Brushed Nickel) is rated 4.8 out of 5 by 86.
Rated 5 out of 5 by from Nice and compact, user friendly for easy filter replacements. Water tastes, smells and feels so much better. Great to have the many undesirable elements removed. My cats would not drink the tap water, I bought distilled or purified water for all of us, they drink this water!

Rated 5 out of 5 by from My husband and I chose Pelican Pro 6-Stage RO because we were concerned about contaminants in our water, and tired of buying bottled water. After ordering the system, we followed the instructions along with YouTube videos and help from the CSR at Pelican who answered a question about a valve/tube. We are quite satisfied with our purchase. Would recommend to others considering a water purifier.

Rated 5 out of 5 by from So far, so good! I was surprised that the connections are just pressure fit. After one week, no leaks so, hopefully that will be the case for the long term. Definitely a good idea to heat the white and black hoses under very hot water for 3 minutes or so. This will make sure you get these hoses fully over the dispenser inputs. I was pleasantly surprised at the pressure / volume of water coming from the dispenser. I received good advice from my sales person to keep water in a pitcher in the refrigerator, so that if you fill up a pot with cooking water, you're not waiting for drinking water while the system re-fills. My net is that this was a better alternative to getting a water service to deliver 5 gallon bottles to my home. The only difficult part was drilling through the kitchen steel sink to make a hole for the dispenser.

Rated 4 out of 5 by from Taste great! Love how easy it was for the plumber to install... and the water taste great. Only down fall is RO systems waste water while it fills the tank.

Rated 1 out of 5 by from Obnoxiously Loud!!!! I just had this installed last week and it is so obnoxiously loud it is impossible to watch TV or anything else while it is refilling or recycling the water. I used one of Pelican's recommended installers and they left without it in proper working order, wish instructions that didn't work. And when I called the installer to ask about the noise and an inspection they stated it sounded normal and would charge me $195 if they felt it was normal. Highly regret getting this system now.

Rated 4 out of 5 by from Make sure you hav enough room under cabinet to hide the filter and also be prepared to cut a hole in your granite countertops to accept the water faucet

Rated 5 out of 5 by from Great clean water I'd been putting off buying an RO, because I had an expensive Ionizer I hated to chuck, but it didn't filter Uranium which is apparently an issue in LA as my hair analysis showed increasing UR. Most ROs are also too big to fit under by sink and this one fit perfectly. I'm going to buy another one for Palm Springs. Very happy with the tasted of the water and its compact size. One of my patients is also buying one. :-)

Rated 5 out of 5 by from Great Tasting Wpater After years of buying water at Publix or Walmart, now I have great tasting quality water out of my faucet. The installation is easy, the instructions were detailed. And the cost was not at all much. I have only used it for a few days but so far it exceeds my expectation. The only thing I would have preferred was a stainless steel version to match my appliances and existing faucet. The advice from other reviewers to place the backwash drain at the upstream side of the P trap opposite of the garbage dispenser was valuable. Also, to install the drain line, I did not drill a 3/8" hole because my 3/8" bit did not fit into the opening provided on the clamp and i did not want to risk drilling a bigger hole, so I did a smaller hole, and it works fine.

Rated 5 out of 5 by from Excellent Service I found Technical Support to be excellent. Firstly, I hate being a handyman but had to install the Reverse Osmosis System myself. I was a bit of a wreck, but every time I called I found wonderful support and knowledge. I do suggest they add a few lines to their instructions to be more clear about the direction the valves should be in each position. That would be soooo helpful. In the end, total success! I love it! The shower filter is also awesome. You'll notice the difference in your hair in one shower.

Rated 5 out of 5 by from Works great! The best system out there, I bought this about 2 months ago and purchased over the phone because I had some questions about it. I called in and spoke with a rep. who answered all my questions. Easy setup, fast shipping, great tasting water and of course made in USA!! What more could you ask for. We purchased this system to remove fluoride and other impurities so far it’s working great.

Rated 5 out of 5 by from Excellent unit We recently installed a water softener,afterwards our water had a sodium taste. Installed Pelican 6 stage reverse osmosis system, removed all bad taste from water. Installation was simple. The only problem was water wasn’t cold enough coming from the tank.I connected ice maker to water line after it came through purifier,now have great tasting ice and chilled water.

Rated 5 out of 5 by from Love the qualitly, loved the price! I bought this before we moved into our new home. We have used it now for two months. It takes up much less space than our old R/O system. The water tastes great and I'm glad to know that minerals have been put back into the water after filtering. It was a great price!!!!! Cheaper than any I have found, but the best quality! I highly recommend this R/O filter!

Rated 5 out of 5 by from Clean Pure Drinking Water - On Demand I actually purchased my first Pro 6-Stage RO unit in 2015 when I lived in Arizona, which is notorious for "bad" water. In addition I also purchased a Pelican PSE-1800 Whole House Filter-Softener system at the same time, which is still in use. Both systems work flawlessly. When I moved a year ago I took the RO system with me and recently connected it. Because the unit sat un-connected for a year some issues developed internally. This was NOT the fault of Pelican; like most other active devices, if it's not used over a period of time problems develop. I elected to purchase a new RO system replacement which is now installed and life is great again. Additionally, Pelican worked with me and gave me a substantial discount for the replacement system. So, if you want really good tasting water with very little maintenance (change filters periodically) and a company that stands behind their products; Pelican gets my vote 110 Percent.

Rated 5 out of 5 by from Great product Yea no more water diliveries n no more bottle loading installation was easy it just sales person should have ask how was going to installing so so I did not have to wait for that air gap part other wise just working great getting enough water for 6 people in house n telling you we drink lots of water .. and great thing is it’s really great teasting water

Rated 3 out of 5 by from Could not use this system After receiving this unit, I found that my plumbing would require extensive modification to accommodate it. I ended up returning it at a loss of $40 for shipping. This was no fault of the dealer or product, but was due to my own lack of preparedness. BE SURE that you have a suitable setup before ordering to avoid a costly mistake like mine.

Rated 5 out of 5 by from Great taste! We’ve had this for about a month now and we love it! Our rural tap water contains a lot of chlorine and the difference this makes is amazing. Doesn’t take up too much room under the sink at all and was simple to install. The hardest part was drilling a hole through my sink!! Budget another $50 for the 1 1/4 in drill bit you will need :)
Date published: 2018-09-06
Rated 5 out of 5 by from Beautiful on my sink! The Oil Rubbed Bronze faucet looks beautiful in my kitchen, it matches my other sink fixtures perfectly. What is even better than they way it looks is the Pelican uses 50% less waste and the water tastes great. It makes more gallons a day than my old system and has a smaller footprint under the sink! I am very happy with my purchase.
Date published: 2018-08-04
Rated 5 out of 5 by from Pleased with quality and value Recently had Pelican RO unit installed by my plumber based on his recommendation. It replaced a larger more expensive unit we had for a number of years. Water quality seems equally as pure as the previous unit and the Pelican was 1/2 the price it would have taken to replace the old unit using the original company. So far very pleased.
Date published: 2018-04-19
Rated 5 out of 5 by from Water Tastes A Lot Better We bought this because we have a whole house salt water softener system. It made the water taste horrible so I was mainly interested in the re-mineralization stage. Install is never what you think.. took a few hours but no leaks and the taste of the water is sooo much better! I wouldn't even drink our water before. Worth the purchase.
Date published: 2019-05-30
Rated 4 out of 5 by from Appears to work well Purchased approximately one month ago. We still need to send in a sample to see if our arsenic levels are down. It would be very helpful if Pelican sent sampling bottles with the unit in the future so that the customer knows the correct type of container to send in. Just a thought.
Date published: 2019-08-16
Rated 5 out of 5 by from Drinking water filter IS GREAT. I bought it not too long ago I am happy with Taste of water. I was very disappointed with the Installation manual was no help at all. The installation manual needs to be redone. it should be a step by step how to install this water filter. and more picture.
Date published: 2019-12-02
Rated 5 out of 5 by from Easy to install The color chart showing the proper install could be a little larger but all in all, this was a snap to install and set up. Great water pressure out of the tap. I would recommend this to anyone over what I would call a regular under the sink system.

If I'm using your Filter/Softener Combo system, would I need your RO drinking water system? My water source is from the city.

Asked by: Jeffa
If you have concerns over heavy metals, we recommend adding an RO as that will filter things like Lead and Arsenic from the water.

Can the system be connected to your refrigerator water/ice dispenser as well and if so, what additional parts are required.

Asked by: Budharick
If your fridge is within 6 feet of the RO you can. You would need to purchase additional tubing and a Tee to branch it off to your fridge.

How does the remineralizing filter work?  What is the source of the minerals? 

Asked by: JBT2013
The cartridge on the end that offers minerals uses Calcite to add some Calcium and Magnesium to the water.

Can this be hooked up to fridge instead of supplied faucet?

Asked by: Ice27
RO systems require an air gap in most states so the faucet is required to be on the unit.

Does this remove Strontium Or would a water softener or carbon filter be better suited ?

Asked by: adam86
Heavy metals can be reduced with a combination of an RO and a salt based water softener.
