How Long Can You Keep Reverse Osmosis Water

Reverse osmosis (RO) system is a common water treatment technology used to remove dissolved salts, microorganisms, organic matter and other impurities from water. Using reverse osmosis equipment to treat water can bring a variety of effects, including:

1.Removal of dissolved salts:

Reverse osmosis equipment can efficiently remove dissolved salts in water, including sodium, chlorine, sulfate, etc. This is important to improve the taste of the water and make it suitable for drinking.

2.Removal of microorganisms and organic matter:

Reverse osmosis membranes can effectively prevent the passage of microorganisms, bacteria, viruses and organic matter, thereby improving water hygiene and safety.

3.Improve water taste and smell:

By removing impurities from water, reverse osmosis equipment can improve the taste and smell of water, making it fresher and purer.

4.Providing high-quality drinking water:

The treated water usually meets drinking water standards and is therefore suitable for drinking and cooking, providing high-quality drinking water.

5.Protect water equipment:

Using reverse osmosis equipment can reduce minerals and other impurities in the water, helping to protect water equipment (such as kettles, coffee machines) from scale and deposits.

6.Applications in Industrial and Commercial Uses:

Reverse osmosis technology is widely used not only in household purposes but also in industrial and commercial areas where high-purity water is required such as production processes, pharmaceuticals, electronics manufacturing, etc.

Generally speaking, the water treated by reverse osmosis equipment is particularly pure. So how long can this water be stored?

The shelf life of reverse osmosis water in storage is related to the storage conditions. Reverse osmosis water can maintain its pure state for a relatively long time if it is kept clean, sealed, and away from sunlight and sources of contamination in storage and containers.

Here are some general guidelines:


Reverse osmosis water should be stored in dry, clean, sealed containers to prevent the entry of air, microorganisms, or other contaminants.

▪Protect from light:

It is best to store reverse osmosis water in an opaque container or encapsulate it with opaque materials to reduce sunlight exposure. Prolonged sun exposure may cause microbial growth or changes in water quality.


The best storage temperature is normal temperature or lower than normal temperature. Excessively high temperatures may promote microbial growth and may affect water quality.

▪Change containers regularly:

If you use plastic containers to store reverse osmosis water, it is best to change the containers regularly to prevent the plastic material from releasing harmful substances into the water.

▪Regular Inspections and Tests:

Regularly check whether the stored reverse osmosis water is clear and has no odor. If you notice any changes, it's a good idea to get your water tested to make sure it still meets drinking water standards.

Although reverse osmosis water itself does not have an expiration date, proper storage conditions are critical to maintaining its quality. With proper storage conditions, reverse osmosis water may last for several months or even longer, but it's best to check regularly and make sure the water quality meets expectations.
