RO is a process through which water pressure pushes the tap water through a semipermeable membrane that allows relatively small water molecules, but not larger molecules such as dissolved minerals (e.g. Salt) to pass through. Thanks to the process the pure tap water is separated from all other substances found in the water. Here's what a typical RO installation looks like along with some of the maintenance requirements. Fast forward to 13:35 to see if RO operation and troubleshooting.

Note also that many RO fitlers are not as effective in reducing TDS as they claim. In our test of the Top 10 Countertop RO filters we found that many of them still had a TDS of 50 or higher after filtration.

"The sales guy used a TDS tester to justify the need for a RO system" TDS measures the amount of dissolved substances in the water. Often the sales technicians use this as an argument for needing a water filter. The problem is that TDS is not a good measurement of clean water. The main components of TDS are typically calcium, magnesium and bicarbonates that the human body needs. A TDS of 250 ppm for example normally just means that the tap water is high in minerals which is good.

RO systems remove contaminants from water including bacteria, viruses, nitrates, sulfates, fluoride, arsenic and much more. But they also removes healthy minerals such as magnesium, calcium, potassium and sodium. Overall RO filters can remove 100s of substances from tap water with a 99% or higher filtration efficiency rate. Some high pressure professional RO filters such as Blue Water Superior Osmosis even achieve 99.9%. Low cost RO filters on the other hand generally have a much lower efficiency. It's really important that you look at the independent lab tests and certifications of each specific brand and product.

However, for public tap water in Europe and North America RO filters are generally not required. Before purchasing an RO unit or any other water treatment equipment check the quality of your local tap water and what is required to make it safe and tasty. Don't listen to the sales guy.

In this article we clarify the basics that you need to know about RO filter, the pros and cons and the best alternatives to RO water filters.
