Water Filter Part -Pre-Filter:Function: It removes large particles such as dust, sand, and dirt from the water before it enters the main filtration system

The Pre-Filter in a water purifier plays a crucial role in the initial stage of the water filtration process. Its primary function is to remove larger particles and debris from the water before it enters the more sensitive filtration stages. Here’s a detailed explanation of its functions:

Functions of the Water Filter - Pre-Filter:

1.  Removes Large Particles:
The pre-filter is designed to trap larger particles like dirt, sand, silt, dust, and rust, which are present in the water. This helps in preventing these large particles from clogging the finer filters in the purifier (like the activated carbon filter or reverse osmosis membrane), ensuring their longevity and efficiency.

2.  Protects the RO Membrane:
Since reverse osmosis (RO) membranes are highly sensitive to dirt and debris, the pre-filter ensures that the membrane is not damaged by larger particles. This improves the overall performance and life of the RO membrane.

3.  Improves Efficiency of Other Filters:
By filtering out large particles, the pre-filter reduces the load on other filters in the purifier (like the carbon filter and UV system), allowing them to perform more effectively and efficiently.

4.  Reduces Maintenance Needs:
By capturing large particles, the pre-filter helps reduce the frequency at which the other filters need to be replaced or cleaned, ultimately lowering maintenance costs.

5.  Improves Water Quality:
By clearing out dirt and debris from the water at the very start, the pre-filter ensures that the water that passes through the purifier is cleaner and free of particles that could affect taste or appearance.

Types of Pre-Filters:

• Mesh Filters: These are fine net-like filters that trap large particles.
• Cotton Filters: These can be used in some purifiers to filter out larger impurities.

Overall, the pre-filter is an essential part of the water purification system, ensuring that the water entering the main filtration unit is free from large particles, which helps the entire system work efficiently.
