Reverse osmosis is a popular filtration method advertised to remove many different contaminants in water.
But let’s look beyond the noise. Just how clean is reverse osmosis water? Is reverse osmosis water purified?
Keep reading to find out!
According to the EPA, purified water is water that has been treated to meet the U.S pharmacopeia standards. Purified water is essentially free of chemicals and contains less than 10 ppm of total dissolved solids.
Another definition of purified water is that it has been processed to remove microorganisms.
Reverse osmosis water is water that has been purified using reverse osmosis. It is much purer than regular tap water and is almost only H2O molecules.
Reverse osmosis purification is the process of purifying water with a reverse osmosis membrane. It works by forcing water through a tiny-pored semipermeable membrane under high pressure. Because the pores are so tiny, only water can pass through them, and pretty much all impurities are left behind.
So, is reverse osmosis water purified water? Yes, it usually is.
That being said, RO water does not always count as purified. If the feed water quality is horrendous and the water contains extreme TDS levels, the RO product water is less likely to come out completely purified. The higher the TDS level in your feed water, the more tasking it is for your RO system to eliminate all of it and a TDS level of higher than 10 ppm is highly likely.
Other factors that may affect the purity of RO water include feed water pressure and temperature, membrane age and condition, and pre-treatment.
Generally speaking, reverse osmosis and purified water are both pure and safe for drinking. But because so many factors determine how “pure” reverse osmosis water turns out, purified water might be a bit purer.
But when it comes to judging which is better, we must remember that the healthier drinking water is always the one that contains fewer harmful contaminants. For example, calcium and magnesium are common impurities in water but aren’t harmful. On the other hand, heavy metal contaminants like lead are always harmful.
So if purified water and RO water both contain these contaminants, the better water will be the one with less contamination.
RO water is superior to unfiltered water and provides many benefits. It is mostly free from contaminants including:
As such, the benefits of RO water include:
