Why we like it…

This Countertop Reverse Osmosis Water Filter transforms ordinary tap water into pure, healthy, and delicious drinking water.

Reverse Osmosis (RO) filters have been around of a long time, but as you may already know, we have never been big fans of reverse osmosis. Yes, they make dirty water into very clean water…but in the past there have been drawbacks, like lots of wasted water, difficult maintenance, challenging installations, slow water delivery, etc.

We’ve come upon a new countertop RO system that eliminates some of those problems, and it just might be the answer to your family’s needs.

Unlike most countertop filters, Zero Installation Purifier (Formerly called ZIP) is not a gravity type filter. Gravity filters, while better than no filter at all, come with certain limitations and problems.

Zero Installation Purifier is a true reverse osmosis filter. As such, the water produced is super-clean. And because Zero Installation Purifier has an internal pump it produces water much faster than most reverse osmosis systems…up to 75 gallons a day! That’s an amazing amount of water for such a compact unit.

Zero Installation Purifier purifies water much more efficiently than typical reverse osmosis units, and it also captures all the water typically wasted. That water can be used for other purposes around the house.

Rkin AlcaPure vs Rkin OnliPure Zero TDS.
These two filters are essentially identical except for one significant feature. The AlcaPure reintroduces beneficial minerals into the water once it has passed through the Reverse Osmosis (RO) membrane. The OnliPure does not.
RO technology is so good at cleaning water that it even removes minerals that are generally considered to be beneficial to human health.
  1. Calcium: An essential mineral for bone and tooth health and it helps regulate muscle function.
  1. Magnesium: Also helpful for bones and teeth and helps regulate blood sugar, blood pressure and muscle/nerve function.
  1. Potassium: Helps regulate fluid balance and maintain healthy heart function.
  1. Sodium: Helps regulate fluid balance, blood pressure, nerve/muscle function.
  1. Chloride: Helps maintain acid-base balance and helps with digestion
Let’s talk about TDS
TDS (total dissolved solids) is a type of test commonly, and mistakenly used to attempt to indicate if water is safe to drink. This is misleading. Water can contain all sorts of dissolved solids that are toxic, but it also contains beneficial dissolved solids, (see above). So, a filter that leaves zero TDS is great for offering very clean water but not-so-great because it has removed all the beneficial minerals.
Unscrupulous/poorly informed water filter manufacturers commonly try to scare potential clients by showing TDS test results. TDS is simply NOT a way to determine if there are toxins in your water.
Let’s talk about alkaline water.
Although the water produced by the AlcaPure filter is more alkaline than the water produced by the OnliPure filter, the AlcaPur should never be confused with an “Alkaline Water Ionizer”. Manufacturers of those machines, (which can cost over $4,000!), make a lot of claims about specific benefits to be realized by raising the pH of your body by drinking water produced by their machines. There’s only one problem with that claim…vigorous, peer-reviewed scientific studies show no benefit.
Our bodies work very hard night and day to maintain very specific ranges of alkalinity. Your body will over-ride any attempts to change those parameters.
