11 known bad tastes of RO water and their reasons

1. Reverse osmosis water metallic taste

Many people note the most common metallic taste in their RO water.

Various metals are in tap water, which isn’t always entirely removed by the RO system.

That is one reason many people choose to buy a pre-water filter for their Best reverse osmosis system – it can catch any metals and impurities before they go through the RO membrane.

2. Reverse osmosis water tastes like plastic

Many have complained that the bad taste of home water is very similar to plastic.

It isn’t too surprising when thinking about it – most plastics, such as those found in bottles and storage containers, don’t taste very good.

But there’s another reason water tastes like plastic – it may be because of the storage container.

While you should always use food-grade containers for your RO water, if you leave it in a glass or plastic container for a long time, the plastic may begin to leach into your drinking water.

If you want to solve these water problems, try switching to a food-grade stainless steel container.

3. Purified water tastes weird

The main reason behind RO purifying water’s unpleasant taste is anything introduced between the source water and the RO membrane.

You should use only clean low-mineral water, so it should not have any organic salt, chemical, or other impurities.

Also, it would help if you used proper storage containers to avoid contamination after water filtration.

4. RO water tastes weird after changing the filter

After changing the RO filter, the taste of water depends on how long it has been since your last chance.

While usually there is no significant difference in water taste, the hard water softeners become less effective, and the water is worse in taste.

It would be best if you changed your filters regularly to make sure you’re getting the best tasting and filtered water supply.

5. Reverse osmosis water has a funny taste like chlorine

How pure your water tastes depends on the source of water you put into it.

If there is a lot of chlorine in the tap water, the RO system can’t remove all of it, and you’ll taste a little bit of that chlorine in the resulting purified bottled water.

One solution is to use a pre-water filter for removing chlorine and other chemicals before it goes through the RO membrane.

If the source water is high in magnesium salts, you may be tasting these in your RO water.

The magnesium salt breaks down into hydrogen and bicarbonate ions detectable in your finished water.

You can remove some hydrogen and bicarbonate ions by using a resin filter, but if you still find it too salty for your taste, you can purchase a distilled water filtration system to dilute it.

7. Sulfur Taste/ Rotten Egg Taste

Sulfur taste in water is typical in many areas, mainly where the soil or rock contains sulfur.

It also smells like a rotten egg and usually happens on hot summer days or stored water.

Some people say that reverse osmosis purified water contains a funny sulfur taste, but it is the case in most rare.

The sulfur comes from hydrogen sulfide dissolved in water.

It can be removed by using an activated carbon filter, or you can use a de-ionizing resin to remove the hydrogen sulfate.

8. Tastes Like Regular Tap Water

If your water doesn’t have any other tastes, it’s probably just the pure taste of tap water that has gone through a purification process.

Some people find the unpleasant taste of chlorinated water, while others would never know there was chlorine in it because the bitter taste overwhelms other flavors.

Flushing water taps for 30 seconds and using a carbon filter to quickly remove the chlorine taste from the water.

Factors that affect RO water taste

The amount of minerals dissolved in water affects the taste of RO water.

Water filtered by a reverse osmosis system will always be purer than tap water because it removes many minerals found in regular tap water.

Some minerals are beneficial to your health, while others affect how water tastes.

It is possible to improve the taste of RO water by adding minerals back into it, you can also make it as “good” as bottled water.
