Total Dissolved Solids Or TDS

is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid. TDS is sometimes referred to as parts per million (ppm). You can test water quality levels using a digital TDS meter.

Primary sources for TDS in Receiving Waters

are agricultural & urban runoff, clay-rich mountain waters, leaching of soil contamination, & point source water pollution discharge from industrial or sewage treatment plants.

TDS in parts per million (PPM)

Chart values represent national U.S. averages. Actual TDS levels for geographic regions may vary.


How does your water measure up?

TDS meters measure your water quality using PPM, or parts per million, to give you your water’s “purity score.”

Because we want you to be aware of your water quality, we would like to offer you a FREE TDS meter with a Zero Installation Purifier purchase. Just cover $4.99 shipping for the TDS meter as these two items are shipped from different distribution centers.

Is Zero Installation Purifier BPA free?

Yes, Zero Installation Purifier is made with BPA free plastic.

What are the dimensions of the Zero Installation Purifier?

A: 9.5 inches Wide, 16.25 inches High, and 14.5 inches Deep.For mobile devices, view the Zero Installation Purifier in your space, via Augmented Reality (AR), by tapping a 3D model below.

What is the difference between AlcaPure and OnliPure Editions?

AlcaPure Edition post filter returns Calcium and Magnesium minerals back to water once it has been purified by Reverse Osmosis. This increases the pH to an alkaline level similar to spring water.

OnliPure Edition post filter does exactly the opposite - reduces even the tiniest amount of TDS left over after the Reverse Osmosis to zero. This provides lab-grade purified water quality similar to distilled water. Slight variations in the calibration and accuracy of different TDS meters may result in the TDS reading of 1 or 2 PPM.

For most People, AlcaPure Edition Zero Installation Purifier is the right choice, unless you have been accustomed to distilled water taste.

What if I want to switch editions of the Zero Installation Purifier later?

Switching from the AlcaPure edition to the OnliPure edition, or vice versa, is as easy as ordering a different post-filter and clips for attachment. Filters and attachment clips are available here.

How long does it take to fill the top tank with purified water?

It depends on water quality you use to make purified water and might take up to 20 minutes. On average about 15 minutes.

How much filtered water does the top tank hold?

1/2 Gallon of filtered water.

How often do the filters need to be changed and how much do they cost?

Every 12 Months.


AlcaPure Edition bundle: $49.95 per complete set of 3 filters consisting of two pre-filters and one AlcaPure post filter.

OnliPure Edition bundle: $69.95 per complete set of 3 filters consisting of two pre-filters and one OnliPure post filter. Depending on local water quality, filters may need to be replaced more often to maintain 0 TDS.

Getting an abnormal filtered water taste is a good indication that the OnliPure Ion-Exchange post-filter has been exhausted and needs replacement.

How often does reverse osmosis membrane need to be changed and how much does it cost?

Every 2-4 years. Zero Installation Purifier Reverse Osmosis Membrane costs $49.95. You will know right away if the membrane has failed because the unit will not function as usual. Example: There is less filtered water in the top tank.

How do I order replacement filters?

If you sign up for our filter subscription program during checkout, the replacement filters will be delivered to you every 12 months automatically. Otherwise, replacement filters can be ordered on our website or over the phone.

Does Zero Installation Purifier use proprietary filters available only from RKIN and reseller partners?

Yes, we designed our own filters to make filter changes as easy as possible.

Does Zero Installation Purifier remove the "XYZ" contaminant?

Zero Installation Purifier uses a multi-stage reverse osmosis technology. Reverse osmosis is one of the best ways to purify water when it comes to cost per gallon, speed, and purity of the water. Undersink reverse osmosis water filters have been around for decades and have been extensively studied by the scientific community.

Because of Zero Installation Purifier’s unique design, preventing back-pressure within the RO membrane, it performs as well or better than most high-quality under sink reverse osmosis systems.

The second stage - Carbon Block pre filter alone tackles a multitude of contaminants even before they get to the reverse osmosis membrane.

We understand that you may want to do your own research. So the fastest way to get an answer is to do an online search for "reverse osmosis removes XYZ" and review scientific papers. Replace "XYZ" with a contaminant of your choice. Or you can always contact our customer support here.

What is the warranty on Zero Installation Purifier?

You get an unconditional 1-year money-back guarantee, which includes warranty for the same period. We will even cover return shipping if the product is returned within 30 days of purchase. Free shipping on warranty replacements.

Stellar customer service

That is what I experienced when my Rkin Water filtration system would not complete a cycle; after purchasing new filters. The bundle. Chanel C. was who I was working with, and she directed me to all troubleshooting techniques. Chanel was knowledgeable, and personable, and above all patient. It was a pleasure working with Chanel.


Thank you for the beautiful compliments. We appreciate your business!

Keeping it clean

Overall great machine. Great tasting water. We got the one with alkaline balance. Only wish the pour spout would go quicker and it had clearance to handle standard 1/2 gallon bottle.


We are pleased you are satisfied with our product. Thank you for your feedback and opinion. We will look into this for future designs.

Love this!

I got the RKIN zero installation countertop water filter system and I absolutely love it! I love that it’s a reverse osmosis system that completely filters everything out of the water and then the last stage adds the minerals back in and raises the ph to alkaline. I didn’t just assume it did any of this either. I purchased digital ph and tds meters and tested my tap, previous PUR filter, RKIN filtered water, as well as the waste water from the system. My tap water ended up being fairly high in tds and ph. My old PUR filter dropped a lot of the ph but actually ended up making the water acidic which was surprising and disappointing. Then the water filtered by my RKIN was exactly where I wanted it to be. Low in tds but high in ph. It’s amazing that it can strip the water of everything and purify it and then adding the important minerals back in and making its ph around 8 give or take. The waste water was high in tds and still alkaline in ph, which I was very happy about because it let me know that the filtration system was doing its job but also I love that I can use the waste water for my many plants and now my plants are thriving from it. So technically it’s a zero waste system because I drink the water it filters and my plants benefit from everything else. I haven’t been using this system for long enough to know how durable it is but I can tell that it is made really well and not cheap in any way. The filters only have to be replaced once a year and two years for the reverse osmosis filter so overall I think this is a super win. People might shy away from this unit due to the price but I felt that with how much I’ll save from not having to buy bottled water or cheap pointless PUR filters (which btw are crazy overpriced for how well they don’t work and how they don’t last for as long as these filters not to mention the fact that they turned my alkaline water to acidic by about two whole numbers makes me think they are a completely fake and dead product that does nothing good for anyone that buys them.) This countertop filtration system is probably good for maybe up to two people otherwise you’ll be refilling the base a lot. For me, I got a sealed water pitcher so I filter the water and put it in the pitcher to store in the fridge along with many reusable water bottles so I have plenty at anytime. It took me about a month of research regarding many products and this was the one I landed on and I cannot express enough how happy I am with it. I hope in the future they create another that is similar but with a bigger reservoir and that is when I will upgrade. I will definitely be a customer for a very long time if not for life and I highly recommend to anyone who is wanting the best water in their own home and not some cheap store bought load of ****. This is the real deal. Elegant, efficient, effective and everything I wanted it to be and then some. And, my cat also loves the water and drinks more. Ps. Taking this water and chilling it in the fridge makes some of the best ice cold water I’ve ever had. I live in Portland Oregon now and the water here is great but I’m from Montana and we had amazing water quality there as well. But now that I’ve had RKIN, it’s pure filtered alkaline water at its best and so I use it everything. Highly recommend it for putting in your coffee pot as well. My first cup was like night and day from using my old PUR filter’s water for coffee. I live in a fairly small apartment and didn’t want to mess with the under sink sort of filters so this is the best (in my opinion) alternative if you want the BEST possible water. After all, the body is made up of ~70% water so for me I want the best water. Now I’ve got it and I couldn’t be happier! Thanks RKIN and please keep up the good work!
