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.

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.

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

1/2 Gallon of filtered water.

Every 12 Months.

AlcaPure Edition bundle: $69.95 per complete set of 3 filters consisting of two pre-filters and one AlcaPure post filter.

OnliPure Edition bundle: $89.95 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.

Every 2-4 years. 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. Zero Installation Purifier Reverse Osmosis Membrane costs $69.95.

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.

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

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.
