It works.

We had some trepidation going in; the claims for the Pelican conditioner seemed too good to be true. But it's both good and true. The calcium deposits are a thing of the past, and without wasting tons of water on regeneration cycles or dumping tons of salt into the ecosystem. We also found your customer service rep, Matt, to be extremely courteous, knowledgeable and helpful. Kudos all around.

loving it!

We have only had our water softener for a couple of months, but already we are noticing a big difference in how our skin feels, and our detergent usage. We have well water, which was tested as very good, except for the hardness level, and they recommended the system we now have. We were impressed with their honesty, as they could have insisted we would need something more expensive. We were skeptical about the salt-less system, but after viewing their informative videos that gave info. on both types, could make a decision right for our situation. The sales man was great, not pushy, and gave us space to make a decision. All in all, we will be happy to recommend Pelican Water Systems to any one who needs great water.

No Water Spots

My new Pelican non-salt water softener has not been in for a whole week yet and I am already very impressed with it because leaves No Spots in my stainless steel kitchen sink! I had no idea that would be a perk! I am very pleased with it: No Salt! No Electricity, minimal maintenance. Great product!

Great Product

I just recomended my fourth NS3 water softener to a friend. He is so happy with this unit as all the others friends are. Could not beleive the difference in the water. I have mine for two years now and still works like the same day I installed it. I have a black car that I couldn't wash at my house because it left white spots all over. Since I installed it, I can now wash my black Corvette at home. We are four happy customers from Pelican. NICE JOB

Thumbs up for the NS6

We installed our NS6 about 60 days ago, give or take. We are on well water and had been replacing our tankless water heater about every 3 years. Our second tankless was already making grinding sounds and is not 3 yet. It started getting quieter in about 2 weeks, then grind a little but this morning and for several days it is silent. Plenty of hot water too. The wife is a faucet polisher....she stated she used CLR every 2 or three days.....she is down to every couple of weeks on the CLR treatment. She started talking positive about the softner after only two days...I have a story about my 1 quart mug that I will not tell, for brevity. My commode handle broke. When I took off the tank lid, everything below the water line was like new...the valve above the water level still had scale on it.....I CLR'd the top and now all like new..Have talked one neighbor into buying one... I continue to watch for signs that it is not working but we are getting more and more sure that it is working fine...Now; how long does it last? Thank you Patrick.

Pelican Water Filter

Having the NatureSoft NS3/NS6 has been the best investment I have ever made. Our condo association has well water. I am very pleased to know the money I am saving, not only in the preservation of my new washer, dryer, dishwasher, and shower heads, etc., but the very small amounts of detergents, soap, shampoo, etc., that is needed to clean. No more rings inside toilets, nor calcium nor other mineral deposits, anyplace. And less time having to scrub the deposits as before, leaves me with a lot more time for more important things to do.

Impeccable Service

I am very impress with the level of service and knowledge, as well as the willingness to spend time answering all my questions with such valuable information. I appreciate knowing that it is not necessary to have a plumber reinstall the carbon media which will save hundreds of dollars. Thank you once again.

Amazing Product and Service

I recently discovered that the water in my house is extremely hard and was the cause of significant damage to appliances as well as staining of fixtures, basins, and dishes. I contacted Pelican Water and spoke with Patrick who helped me understand everything I needed to know about hard water and how the NaturSoft system works. After researching different types of water softeners I came to the conclusion that the NaturSoft best fit what I wanted. I wanted a system that softened my water without adding salt or potassium to the water, that required limited ongoing maintenance and expense (only requires a pre-filter change every 6-9 months), that left beneficial minerals in the water, that did not waste water, and that helps reverse the damage caused by hard water. I installed the NaturSoft and immediately noticed that the sink basins I had to regularly clean with vinegar and baking soda to remove hard water stains actually stay clean now! Within a few days of installing the NaturSoft I could see a significant amount of scale buildup dissolving in my dishwasher and the buildup continues to dissolve as time goes on. The water in my house feels and tastes the same as it did before installing the NaturSoft yet I no longer have a problem with mineral scale. It is also worth noting that I have no previous plumbing experience and the NaturSoft was simple and inexpensive to install myself. I had to do some online research to understand how the plumbing in my house works but after I read and learned a bit I was able to get the NaturSoft working without any problems; it took me less than two hours to install the NaturSoft which I think is pretty good for a first-time plumber. Thank you Pelican for helping me solve a big problem simply and affordably! A special thanks to Patrick for answering so many questions, being so responsive, and for all of your help.

It is working

Dear Sirs, I have been using the system for the last four months, in my country, Bahrain, Arabian Gulf, and I am happy to say that it did work, despite the geographical location, and the difference in climate and water quality from that of the US. Thank you

We have had the whole house water filter for over a year and it is amazing to see the filters when they are changed. Makes a big difference with the system. Glad we have it.
