The Sediment Filter in a water purifier is a crucial component that plays a vital role in removing solid particles from the water. Here’s a detailed explanation of its function:

Functions of the Sediment Filter:

1.  Removes Suspended Particles:
The primary function of the sediment filter is to remove suspended solids in the water, such as dirt, sand, silt, clay, and other particulate matter. These particles are typically visible to the naked eye and are often found in untreated or surface water sources.

2.  Prevents Clogging of Finer Filters:
By filtering out larger particles, the sediment filter protects the more sensitive filters in the water purification system (such as the activated carbon filter and reverse osmosis (RO) membrane) from becoming clogged. This ensures the longevity and optimal performance of these subsequent filters.

3.  Improves Water Clarity:
As sediment filters capture particles from the water, they help improve the clarity of the water, making it look cleaner and more appealing.

4.  Enhances Overall Filtration Efficiency:
The sediment filter works as the first line of defense by removing large particles. This allows the other filtration stages to focus on finer contaminants, such as chemicals, bacteria, and dissolved salts, which improves the overall filtration efficiency of the entire system.

5.  Protects Appliances and Plumbing:
By removing sediments, the sediment filter helps prevent the build-up of particles in the plumbing system, faucets, and appliances like water heaters. Over time, sediments can cause wear and tear on these systems, and the sediment filter acts as a safeguard.

6.  Reduces Water Taste and Odor Issues:
While the sediment filter doesn’t directly remove chemicals or bacteria, by clearing out large debris, it can improve the overall taste and clarity of the water, especially when combined with the activated carbon filter.

Types of Sediment Filters:

• String Wound Filters: Made of wound strands of thread, this type of filter effectively traps particles.
• Pleated Filters: These have a folded structure that increases surface area for more efficient filtration.
• Spun Filters: Similar to string wound filters, these are made by spinning threads together to form a dense network of fibers that capture debris.

In summary, the sediment filter is an essential part of the water purification system, as it acts as a protective barrier to remove large particles and debris, ensuring that the other filters in the system can perform at their best.

What Impurities Sediment Filters Remove?

As the name suggests, a sediment filter acts as a barrier against different types of sediments or suspended solids. It sieves or holds back physical impurities like dust, dirt, sand, silt, clay, and other solid particles. Mostly the particles that are visible to the naked eye are treated by sediment filters during the process of water purification.

Why Sediment Filters are important?

A Sediment filter usually acts as the first stage of water purification. Being the first line of defence, its core function is to remove the physical impurities or particulate matter from water. It prohibits all the solid particulate from entering your filtered water and enhances the filtration efficiency of RO membrane and UV filters.

It is not responsible for changing the taste or smell of water. It is one of the preventive filtration methods and does not remove chemicals, heavy metals, bacteria, viruses, or dissolved solids in water. These impurities are removed by further stages of RO and UV purification.

Pureit uses gradient sediment filters which are efficient to entrap impurities as small as 5 microns. The sediment layers are tightly wound in layers, ranging from 5-10-15 microns to ensure most efficient filtration.

When is it advisable to clean/replace a Sediment Filter?

Sediment filters need to be cleaned and maintained at regular intervals. You can clean these filters on your own in every 4-6 months or you can call brand experts for the first time and take their help for maintenance, replacement, etc. Always refer to the product manual before changing the sediment filters on your own.

Replacement of sediment filters also depends on the source of the water and the type, quality, etc. If your water supply seems to be muddy or unclear, it is advisable to change the sediment filters in every 6-8 months.
