It is natural to wonder what reverse osmosis water tastes like, especially when hearing about this kind of water treatment process for the first time.
I definitely know I was curious!
Let’s look at the smells and tastes of RO water in more detail.
So, what does reverse osmosis water taste like?
Properly purified reverse osmosis water tastes like nothing really. Some people like to describe it as “flat”. This is because RO water is almost pure H2O, lacking mineral content. And it’s the minerals in water that gives it its round taste.
So, does reverse osmosis water taste good or not?
It certainly tastes better than low-quality tap or well water full of contaminants. But ultimately, the absence of impurities in RO water provides a blank canvas, but it can be remineralized if the taste is not to your liking.
The final composition of reverse osmosis water can vary depending on various factors, such as the source water and the specific filtration process. Source water, which refers to the original water used as input, can have different impurities that may influence its flavor. Excess contaminants such as salts may leave a salty taste in the RO water, or If your RO system does not have a carbon post-filter, the water may pick up some flavor from the storage tank.
When we say “no taste”, it signifies that the reverse osmosis filtration process has been highly efficient, resulting in pure water free from undesirable flavors. This means that harmful contaminants, if any, have been effectively removed, ensuring the water’s quality and safety.
Yes, this may happen depending on the cooking method. For instance, the boiling process may lead to the leaching of minerals and other substances from the food into the liquid, potentially altering its taste. As a result, some of the original flavors in your food could be lost or diminished.
There are a lot of reasons why your RO water may develop a bad taste, particularly if it is a plastic taste!
If the taste of your reverse osmosis water is indistinguishable from unfiltered tap water, it means your RO system’s filters are not working as they should and will need to be replaced.
Water odor is often caused by hydrogen sulfide, which smells like rotten eggs. Reverse osmosis systems with activated carbon filters can remove low levels of hydrogen sulfide, but high concentrations may remain.
Different chemical forms of sulfur have varying filtration capabilities. While sulfite and sulfate can be eliminated, reverse osmosis membranes cannot filter hydrogen sulfide due to its small size.
Luckily, you can improve the taste of your reverse osmosis water in various ways once you have identified the cause of the issue:
The first and easiest thing to try is flushing and sanitizing the RO system itself. To flush your RO system, open the RO faucet and drain the storage tank, then let it refill and repeat the process. To sanitize the system, use a solution of household bleach or hydrogen peroxide.
Your home water pipes may need to be flushed due to the accumulation of various minerals or dirt. This will help eliminate any off-flavors or odors that may be causing the reverse osmosis water to taste bad.
Ensure that you are replacing your filter elements on schedule. Replacing the filter elements in your RO system should eliminate any bad tastes or smells due to a clogged RO membrane or malfunctioning pre or post-filter.
A carbon post filter will ‘polish’ your RO water once it exits the storage tank. This will eliminate any residual odors and tastes before consumption.
If your feed water has high levels of specific contaminants, you may want to consider additional pre-treatments.
