Water filtration machines with convenient features are increasingly popular among households. However, clogging in RO filters is a common issue. What causes RO filter clogging? How to address this issue? Follow our article at Mytour!
1. Why Do RO Filters Get Clogged?
RO filter clogging occurs due to various reasons, including:
- - Frequent usage of water filtration machines over an extended period.

- Poor quality of the water source, prolonged operation of water filtration machines, and irregular maintenance contribute to RO filter clogging.
Checking for RO Filter Clogging

To check if your RO filter is clogged, you can directly feed water into the filter inlet and compare the ratio of wastewater to pure water.
3. Troubleshooting When RO Filters Get Clogged
3.1. Cleaning the Filter Core
To address a clogged RO filter, clean the filter core by removing it from the unit. Then, inspect the inner membrane for accumulated dirt. Clean the RO filter thoroughly and reinstall it in its original position.

3.2. Replacing the RO Filter
Cleaning the filter core is a simple way to fix the issue of clogged RO filters. However, cleaning the filter core gradually weakens its performance and reduces water quality. Therefore, you may consider replacing the RO filter instead.

Typically, RO filters have an average lifespan of about 2 years (24 months). Depending on the filtration level, capacity, and source water, the lifespan of RO filters may vary.
4. Some Usage Tips
To minimize the risk of RO filter clogging, consider the following:
- - Regularly check the filtration system and other components of the water filter.

- Replace the filter when it reaches its service life.
