Sediment Filter: Ultimate Guide & Best Price in India

Snippet 

A sediment filter is a pre-filtration device used in RO water purifiers to remove dirt, sand, rust, and other physical impurities from water. The price of a 10-inch sediment filter in India typically ranges from ₹50 to ₹250, depending on brand, material, and quality.

Factor:
According to a recent study by the Bureau of Indian Standards (BIS), up to 30% of domestic water purifiers fail prematurely due to improper sediment filtration. That’s why installing the right sediment filter is critical—not optional.

In the age of rising pollution and hard water, water purification isn’t complete without a high-quality sediment filter. Whether you're an individual buyer, a wholesaler, or a technician, understanding what a sediment filter is and how much it costs is crucial.

What is a Sediment Filter?

A sediment filter is the first line of defense in most RO water purifiers. Its main role is to trap and block physical particles like:

• Dirt

• Sand

• Rust

• Scale

• Other large suspended solids

These filters protect the RO membrane and other downstream filters by ensuring that coarse contaminants don't enter the finer stages of filtration.

They are commonly made from:

• Polypropylene (PP)

• Cotton wound material

• Pleated cellulose or polyester

Types of Sediment Filters Used in RO Water Purifiers

Let’s break down the main types of sediment filters:

1. Spun Filters (Melt-Blown PP)

• Most common type

• Made of layers of polypropylene

• Good for fine and medium-sized particles

• Lifespan: ~3 months

2. String Wound Filters

• Made with cotton or polypropylene string wrapped around a core

• High dirt-holding capacity

• Used for more industrial/large-scale RO systems

3. Pleated Filters

• Washable and reusable in some cases

• More surface area

• Suitable for high flow rate applications

4. Cartridge Filters

• Standard 10-inch or 5-inch sizes

• Replaceable and universal

• Used in most domestic RO water purifiers

Why You Need a Sediment Filter in Your RO Purifier

1. Extends RO Membrane Life

Sediment filters prevent physical clogging, thus extending the life of your expensive RO membrane.

2. Improves Water Quality

Even before chemical filtration, water clarity improves dramatically.

3. Reduces Maintenance Costs

Avoid frequent servicing by catching impurities early.

4. Essential in Indian Water Conditions

Due to high TDS, rusted pipes, and turbidity in many Indian regions, sediment filtration is non-negotiable.

FAQs

Q1. How often should a sediment filter be changed?

Every 3–6 months depending on water quality and usage.

Q2. Is a cheaper sediment filter effective?

Yes, but ensure it has a good micron rating and fits well.

Q3. What is the best size for a domestic RO?

10-inch PP sediment filters are standard for most domestic systems.

Q4. Can I clean and reuse it?

Only pleated filters are washable; PP spun filters should be replaced.

Conclusion

Sediment filters may look simple but they’re critical to the health of your water purifier. Whether you're maintaining your home RO system or supplying filters in bulk, understanding the types, uses, and pricing of sediment filters is essential.
