Good water, easy setup

I bought the Zero Installation Purifier about three weeks ago. It was super easy to get going, just plugged it in and filled it up. The water tastes way better than what I was getting from the tap. Shipping took about a week to get here, which was fine. Overall, I'm pretty happy with it. My old pitcher filter just wasn't cutting it anymore.

U1 system still great

I ordered the U1 Countertop Reverse Osmosis System last month, which was my third RKIN purchase. Just like my previous orders, everything arrived quickly and was well-packed. The system works perfectly, and the water tastes consistently pure. It's why I keep coming back.

AlcaPure is fantastic!

Seriously impressed with the AlcaPure Reverse Osmosis System I got! The water quality is amazing, truly a noticeable difference. Installation was straightforward, even for me, and the instructions were clear. I especially love how compact it is on my counter. This was a fantastic upgrade for my kitchen, and I've already told my sister about it. Definitely buying replacement filters from here when the time comes!

Is RKIN actually good for fluoride removal? Or should I just go with something like a Berkey filter instead for that?

D Derek Romero 1 month ago

I use their AlcaPure and it definitely targets fluoride. They even sell a specific fluoride removal filter if you're extra worried about it.

A Andre 1 month ago

Berkey's good but RKIN's RO systems are usually more comprehensive for a wider range of contaminants, including fluoride. I switched from Berkey personally and noticed a difference in taste.

Hey, wondering if anyone knows if RKIN does a military discount? My buddy was asking about it for a new filter system.

M Mike Beaumont 4 weeks ago

Yeah, I'm pretty sure they do. I saw it mentioned somewhere when I was looking at their site for my U1 system. Like, you have to verify or something.

S Sarah 3 weeks ago

They do, but it's usually not stackable with other offers. So if there's a big sale, sometimes that's a better deal overall.

Does anyone know if RKIN lets you combine coupon codes? I have a referral thing from a friend and I also saw a first-time buyer discount.

G Greg C. 2 weeks ago

Nah, pretty sure you can only use one at a time. Most places are like that unfortunately.

J Jared Doyle 1 week ago

Yeah, tried that before. The system only lets you enter one code at checkout. Had to pick between the referral and a site-wide sale.

Thinking about getting the Zero Installation Purifier but I'm in an apartment, is it really 'zero installation'? Or is there some plumbing I gotta mess with?

B Beth S. 3 weeks ago

Nah, it's legit zero. You just plug it in and fill the tank. No messing with pipes or anything. Super easy.

E Emma Z. 3 weeks ago

Can confirm, I literally just pulled it out of the box, plugged it in, filled it, and hit start. Easier than setting up a coffee maker.

How long does shipping usually take to like, California? Looking at getting one of the countertop RO systems soon.

B Beth Torres 1 month ago

I'm in LA and mine got here in about 4-5 business days, pretty standard.

A Andre 4 weeks ago

Mine was maybe a week, but that was during a holiday sale so things might have been slower then. Usually pretty quick though, afaik.
