If you use a Reverse Osmosis (RO) water filtration system, you need to know when to change the filters. The RO filters are the heart of the system and play a vital role in ensuring the quality of the water you drink. This article will discuss the best time to change your RO filters and how often you should do it.
Understanding the RO System
Before we dive into the best time to change your RO filters, let's first understand how the system works. An RO system consists of a pre-filter, a membrane, and a post-filter. The pre-filter removes sediment, chlorine, and other contaminants, while the membrane removes dissolved solids like minerals and salts. The post-filter is responsible for removing any remaining taste and odour.
Factors that Affect Filter Life
The lifespan of an RO filter depends on various factors, such as the quality of the feed water, the number of contaminants, and the frequency of use. If the feed water has a high concentration of contaminants, the filters will get clogged faster, and you will need to change them more frequently. Similarly, the filters will wear out more quickly if you use the system frequently.
When to Change the Pre-Filter
The pre-filter is your RO system's first line of defence, and it is essential to change it regularly. The pre-filter should be changed every 6 to 12 months, depending on the feed water quality. If the feed water is high in sediment, you may need to change the pre-filter more frequently.
When to Change the Membrane
The membrane is the heart of the RO system and is responsible for removing dissolved solids from the water. The membrane should be changed every 2 to 3 years, depending on the quality of the feed water and the frequency of use. If the feed water is high in contaminants, the membrane will wear out faster, and you will need to change it more frequently.
When to Change the Post-Filter
The post-filter is the last line of defence in your RO system, and it is responsible for removing any remaining taste and odour from the water. The post-filter should be changed every 6 to 12 months, depending on the quality of the feed water and the frequency of use.
Signs that Your Filters Need to be Changed
Apart from the recommended time intervals, some signs indicate that your RO filters must be changed. If you notice a change in the taste or odour of the water, it may be time to change the filters. Similarly, if you notice a decreased water pressure, it may be due to clogged filters.
How to Change Your RO Filters
Changing your RO filters is a simple process that you can do yourself:
- Turn off the water supply to the system.
- Release the pressure from the system by opening the faucet.
- Remove the filter housing and replace the old filter with a new one.
- Reassemble the filter housing and turn on the water supply.
Conclusion
In conclusion, the best time to change your RO filters depends on various factors, such as the feed water quality, the number of contaminants, and the frequency of use. It is essential to change your filters regularly to ensure the quality of the water you drink. If you notice any signs that indicate that your filters need to be changed, do not hesitate to replace them.
