Customer Reviews
Good system, easy install
Just received my Under Sink Water Filter. Installation was pretty straightforward, even for me who's not super handy. All the parts were in the box. Water tastes clean now. It's a nice change from buying bottled water all the time. Good purchase.
ZP unit, good support
I ordered the Zero Installation Purifier about a month ago. Delivery took 5 days to reach Denver, which was reasonable. Setup was easy, just plug it in. The TDS went from 280 to 20. I had a question about the AlcaPure Filter replacement schedule and customer support responded within a day with clear instructions. Quality feels solid.
Perfect water every time
Got the Countertop Water Purifier and I'm so happy with it! The water tastes amazing, way better than what came out of my tap before. It was super easy to set up, took like 5 minutes. Definitely noticed a difference in my coffee and tea. Will totally buy from RKIN again!

hey, anyone got one of those RKIN countertop purifiers? I'm in an apartment, thinking about the zero installation one. is it really as easy as they say? also, how long does shipping usually take to, like, California?
thinking about getting the whole house system but wondering if there are any good sales coming up? or like a first-time buyer hookup type deal? trying to save some cash you know.
