I have the system from Pelican. Our water isn't really hard to begin with, but I love the carbon filtering. Every tap has bottled water taste.

the rhino water filter is GREAT! we've had it for 6 years because we live in Louisiana and they say the cancer rates here are higher. i don't know if it will help with cancer, but mentally i feel better drinking my crystal light knowing that the water is filtered. let's not get started on artificial sweeteners;) another topic for another day...

anyhow, i did a good bit of "research" before deciding on the rhino. I've been very pleased with it. i wish there was a way to keep the hoses outside from using the filter. i don't think any of the filters have that ability. at least they didn't 6 years ago.

I installed both the whole house carbon filter system and Natursoft Salt-free system in June 2013.

The Pelican Natursoft salt free system does nothing to help my hard water issues. It claims to condition the water to prevent internal scaling in appliances and water heaters, etc...; After 2.5 years, i suffered from damage to my water heaters and other electronic systems from the hard water in my city (14 gpg level). IT DOES NOT WORK SO I RECOMMEND BUYING ANY SALT-FREE SYSTEM TO ADDRESS YOUR HARD WATER PROBLEMS.

Pelican has shady customer service and reviewing system. Take note that none of their "reviews" on their site are negative, and they surely failed to post my 1-star negative review.

I wish Pelican Water should have just recommended me to purchase their salt-based ion exchange system (traditional system), as I would be a happier customer.

Their 90-day warranty is bologna! You won't be able to validate the effects of hard water damage to your system/appliance in that time. The damage will have to take much longer time (over a year, in general) to manifest itself.

Pelican Water - DON'T RECOMMEND THEIR SALES PRACTICES

Salt-free "softener" - DON'T BE FOOLED BY *ANY* SALT-FREE SYSTEM FOR HIGH LEVELS OF HARD WATER

I threw that piece of $h!t in the garbage.

Got myself a Kinetico salt exchange softener to replace that piece of junk.
