Good system, slow delivery

I ordered a Salt-Based Water Softener mid-month. The ordering process online was straightforward, no issues there. Shipping took about 8 days to get to my place in Indiana, which felt a little long. Installation was mostly easy, I did it myself with the guide. The water quality is much better, I noticed a difference in my shower right away. Filters seem well made.

Works fine, easy setup

Got the Under Sink Water Filter last week. It was easy to install under my kitchen sink. Water tastes good now, better than before. No leaks or anything. Shipping was pretty quick.

Thinking about getting a whole-house filter from Shell Water Systems. Are these things actually good? Like, for real, or is it just marketing hype?

S Steve Vargas 3 months ago

Yeah, I got their whole house combo like six months ago. Seriously, water tastes way better, and my skin feels less dry. Pretty happy with it.

O Omar L. 3 months ago

I was skeptical too, but my neighbor got one and raves about it. Says their water test after install was really good, like 97% of the bad stuff gone. Thinking about pulling the trigger myself.

hey does shell water systems ever have sales on their whole house filter setups? or like a discount code for new customers?

S Sam Bennett 4 months ago

They definitely do sales, especially around holidays like Black Friday or New Year's. I got a couple hundred bucks off my system last spring. Keep an eye out.

B Beth Kaur 4 months ago

Yeah, check their site directly. I think they usually have a new customer discount or something popped up when you first visit. Sometimes they do free shipping on replacement filters too, which is nice.
