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.

Rated 5 out of 5 by from Do it your self installation The quality of the equipment was outstanding. I found it difficult, being an 80 year old man working under the kitchen sink. But the color coded tubes all went together nicely with clear instructions. Glad to be finished.

Rated 5 out of 5 by from Finally, "pure water"! My 2nd purchase from Pelican... My 1st is the shower filter. It's great and easy to change the filter, no more itchy skin. 2nd purchase was the under the sink 6-Stage Reverse Osmosis system. No more carrying those gallon bottles of drinking water! Now clean and good tasting water for drink and cook with - making coffee, steaming veggies, etc.. The system was installed by my son and a friend, and only problem was water "burping" from the small hole in the faucet and water was running all over the counter. I called Pelican's service dept. and it was solved quickly: shorten the white hose from the faucet to the drain and make sure it runs downhill with no kinking or loops in the line. Working great now. My water not only tastes good, but no more chlorine smell and it's free of the ugly stuff county water leaves in when they "filter" it. Bonus was the service I received - before purchasing, Michael was so patient and really spent time explaining to this great-grandma (75) how the system worked and about replacement filters. I signed up for auto shipment which is another bonus from Pelican. I recommend the Pelican systems for their products and service.

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.
