Customer Reviews
Shower filter easy install
Got the Shower Filter and it was super easy to put in, like, five minutes max. Water feels softer, which is nice. Didn't expect it to make such a difference, but it did. Happy with it.
Wellness System, good quality water
I ordered the Wellness Water System and an extra set of replacement filters. The website was pretty straightforward for ordering, though I did spend a little time comparing it to a few other brands. Shipping took 6 days to get to my place in Arizona, which was within their estimated window. Installation of the Wellness system was manageable; the instructions were clear, and I didn't need any special tools. The water quality is noticeably better. I tested it with the pH Test Kit I bought separately and it showed a good alkaline level, which is what I was hoping for. Customer support answered a question I had about filter replacement frequency pretty quickly over email. Overall, a solid product and experience.

Anyone know if they usually have good deals around Black Friday or Cyber Monday? I'm trying to decide if I should wait to buy a whole house system.
Thinking about getting one of these systems, but I'm kinda handy, can I just install it myself or do I need a plumber? Just for an under-sink one.
