Ensuring that drinking water is pure and safe is a necessity in every household. The water purifiers in our homes consist of various water filters that remove unwanted dirt, impurities and other harmful particles and chemicals.

There are multiple filters used in a water purifier and each of these filters play a different role in the purification of water. Sediment filter, being one of the pre-filters, plays an important role in the initial stages of the filtration process.

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.


  • Is a sediment filter necessary?

    Let us see What is a sediment filter? It is a barrier against different types of sediments or suspended solids. Sediment filters are quite an important component in the water filtration system. If the water has dirt, debris, or fine particulates, then a sediment filter is necessary.

  • Does sediment filter enhance water quality?

    Sediment water filters can help to remove any visible particulate matter or any particles of dirt, sand, dust, and debris which can be caught in its micron-rated capacity. However, these filters do not remove any chemicals, bacteria, heavy metals, or dissolved particulate matter. They don't help to improve the taste or smell of the water

  • Can I use a carbon filter as a sediment filter?

    Sediment filters can help in catching dirt while carbon filters help in capturing organic compounds which can cause bad tastes and odors. It is because a carbon filter can remove particles by adsorption, it is not considered a good sediment filter.

  • When would you use a sediment filter?

    If the tap water at your home has visible particulate matter, and any particles of dirt, dust, sand, and debris which can be caught on by its micron-rated capacity, you must use a purifier that has a sediment filter in it.

  • How often should I change my sediment filter?

    If you want to know when to change sediment filter, then it must be changed every six months to one year. However, the best way to know is to observe the water pressure at your home. When the pressure begins to drop you must change the filter.
