        How to use a TDS Meter by RKIN

        What are total dissolved solids or TDS?

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

        Frequently Asked Questions

        Is Zero Installation Purifier Certified by a third party and BPA free?

        Yes, Zero Installation Purifier is made with BPA-free plastic and certified by IAPMO R&T to NSF/ANSI 58 standard for the reduction of TDS, Fluoride, Lead, PFOA/PFOS, Hexavalent Chromium, and Trivalent Chromium. Please click here to view the certification listing page and click here for individual contaminant reduction rates.

        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 the main product image at the top of the page.

        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 membrane. 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 the water quality you use to make purified water, and it 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?

        Please refer to the section below for all details on the replacement filters.

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

        How do I order replacement filters?

        If you sign up for the 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 this system 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 extensively studied by the scientific community.

        Because Zero Installation Purifier's unique design prevents 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 search online 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 if I have questions or need support?

        4 Stages of Advanced Filtration:

        Your water quality may affect the longevity and replacement frequency of the filters. The Zero Installation Purifier Countertop Reverse Osmosis Water Filter comes ready to use out of the box. All the filters and reverse osmosis membrane are preinstalled. You don't need to purchase them separately when you buy the water system unless you are purchasing spares for the following filter change. 


        First Stage Filtration - A 5-micron sediment filter with a unique gradient pore structure traps larger particles in its outer layer and smaller ones in the inner layer, effectively removing particles such as sand, sediment, and rust.

        MPN: RC-FT-82. Replace every 12 months or as needed.

        Second Stage Filtration - Coconut-based activated carbon block filter with high adsorption capability removes harmful chemical residues and carcinogens such as VOCs, THMs, and pesticides, eliminating foul odors and bad taste. MPN: RC-FT-92. Replace every 12 months or as needed. Or an Anti-Scale Version of the Carbon Block Filter for use with extremely hard water.

        MPN: RC-FT-90. Replace every 12 months or as needed.

        Third Stage Purification - NSF/ANSI 58 Certified reverse osmosis membrane with 75 Gallon Per Day filtration capacity purifies water by blocking virtually all harmful contaminants. It's the heart of the reverse osmosis system.

        MPN: ZIPM75. Replace every 24 months or as needed. 

        Hardness over 10 gpg (171 mg/L) may reduce the lifespan of the RO membrane. If the filtered water production decreases over time, please replace the RO membrane and substitute the 2nd stage Carbon Block filter with a PPH Anti-Scale Carbon filter to prevent premature RO membrane failure due to hardness build-up.

        Fourth Stage - OnliPure™ The specialty Ion Exchange Media inside our OnliPure Post Filter reduces any leftover contaminants after the Reverse Osmosis process to zero TDS. Measure and confirm from your home with a simple TDS meter.

        - OR -

        AlcaPure™ Polishing Alkaline Post Filter returns beneficial minerals – Calcium and Magnesium to purified water for the best taste. It also increases the alkalinity of the water to a perfectly balanced level of 7-8 pH.

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

        AlcaPure Post Filter, MPN - RC-ZIPFAP, Replace every 12 months or as needed.

        OnliPure Post Filter, MPN: RC-DIPFL2.5x10. Replace as needed.

        Love my new RKIN!

        We absolutely love this machine! We had been purchasing 14 distilled water bottles per week and it is such a relief to be able to do it at home-plus we were lacking the minerals (per my naturopath) and purchased the unit that adds the minerals back which is a double win! It’s easy to use, attractive on the counter, and overall wonderful. Also, the customer service reps are great and respond immediately (even on a Sunday). Thank you RKIN we are happy to support your product and work!

It’s amazing to know that it's making such a positive difference for you, both in convenience and health benefits. Switching from 14 distilled water bottles per week to having fresh, mineral-rich water at home sounds like a big win indeed! We're glad you find the unit easy to use and attractive—it’s always nice to have a product that not only works well but looks good too. And thank you for the shout-out to our customer service team! We’re proud to hear they were able to assist you promptly, even on a Sunday. Your support means the world to us. If you ever have any more feedback or need assistance in the future, feel free to reach out. Cheers, The RKIN Water Systems Team

        I love this! It saves me so much money on water, as my entire household drinks plenty. Water isn’t very hard in my area so I haven’t had to replace the filter yet, even though it’s been seven months. After buying this I can no longer drink bottled water because this taste so much better! I highly recommend. This was my second one in four years. I prefer room temperature water so this model works well for my family.


        Hello Kaylean, we're thrilled that our RKIN water system has proven to be such a valuable addition to your household! Knowing it not only saves you money but also delivers superior taste compared to bottled water brings us immense joy. We take pride in offering a product that enhances drinking water quality while reducing single-use plastic waste.
