Customer Reviews
My new filter system
So, I finally got around to replacing my old water filter and decided on the RKIN Under Sink Water Filter. It was a bit of a project getting it installed, but honestly, it wasn't too bad. My husband helped, and we got it done in an afternoon. The water coming out of the tap now is so much clearer, and you can really taste the difference. It's been great for making coffee and just drinking straight from the tap. Felt good about the whole thing, like we made a healthy choice for the house.
Zero Installation Purifier Review
I ordered the Zero Installation Purifier about a month ago. The ordering process was straightforward on their website. It arrived pretty quickly, took about 5 days to reach Denver. Installation was truly zero; just plugged it in and filled the reservoir. The water quality is noticeably better, no more weird taste. I did have a question about the filter replacement schedule and used their online chat support, which responded within minutes. They were helpful. The system itself feels sturdy, not flimsy plastic. It's on my countertop and looks decent enough. Overall, a good experience, and the water tastes clean.
Consistent Filter Quality
This was my third time ordering the Replacement Filter Set for my Zero Installation Purifier. Each time, the filters have arrived quickly and in perfect condition. I've been using RKIN for over a year now, and the water quality has been consistently good. I appreciate that I can rely on them for the right filters without any hassle. No complaints here, just reliable service and products.
Good Water Taste
Got the Countertop Water Purifier. Shipping was fast. Water tastes way better now. Easy to set up. Happy with the purchase.

Can I use more than one coupon code on an order? I have a newsletter one and saw a military discount too.
Thinking of getting the Zero Installation Purifier, but how long does it usually take to ship to, say, Miami?
