Sediment water

filter

A sediment filter is usually the first stage in a multi-stage water filtration system. Its main function is to remove physical particles from water before it reaches other filters or your tap.

  • Removes visible, solid particles from water such as:

    • Sand

    • Silt

    • Dirt

    • Rust flakes

    • Other debris

Prevents clogging of other filters (carbon, RO membranes) and protects appliances like water heaters, washing machines, and dishwashers.

Key Features:

1. Material:

  • Commonly made from polypropylene (PP)

  • Types include:

    • Melt-blown (spun): Dense, compact material – standard option

    • Pleated: Higher surface area – can sometimes be rinsed and reused

    • String-wound: Ideal for well water or heavy sediments

2. Micron Rating:

  • Measures the size of particles it can filter out

  • Common sizes: 1, 5, 10, 20, 50 microns

    • Lower micron = finer filtration

    • Example: 5 micron removes more particles than 20 micron

3. Flow Rate & Pressure:

  • Larger micron sizes allow faster flow but less filtration

  • Smaller micron sizes filter more but may reduce water pressure

4. Reusability:

  • Most filters are disposable

  • Some pleated filters can be cleaned and reused once or twice

5. Visibility:

  • Often installed in a clear filter housing so you can visually monitor dirt buildup

6. Installation Use Cases:

  • Whole-house systems (POE)

  • Under-sink filters (POU)

  • Reverse osmosis (RO) pre-filters

  • Well water filtration

When to Replace It

  • Replace every 3–6 months (depending on water quality and usage)

  • Office water filtrationSigns it needs replacing:

    • Drop in water pressure

    • Visible dirt/darkening in the filter

    • Bad smell or taste in water
