Cartridge Filter 10 inch

Pearl Water Filter Cartridge 10 Inch (PP Spun, 5 Micron)

If your RO purifier is clogging fast, losing pressure, or letting cloudy water through, the problem usually isn't the membrane — it's what's happening before the membrane. The Pearl Water Filter Cartridge is a 10 inch PP spun cartridge filter built to trap sand, rust, silt, and suspended solids at 5 micron accuracy, before that dirt ever reaches your RO system. Made from layered polypropylene using melt blown technology, it's a standard-size cartridge filter that fits most universal RO housings used in Indian homes, offices, and small commercial setups. Whether your supply is borewell water, municipal water, or tanker water, this cartridge acts as the first line of defense in your water purification system — protecting the membrane, improving flow rate, and cutting down on maintenance costs. It's a small, inexpensive part that quietly does a lot of heavy lifting.

What Is a 10 Inch PP Spun Cartridge Filter?

A PP spun filter cartridge is a cylindrical sediment filter made by spinning strands of polypropylene fiber around a hollow core. As the fibers wind layer over layer, they create a gradient density structure — looser on the outside, tighter toward the core. Water has to pass through all of these layers, and each one catches progressively finer particles.

This matters because raw water, especially from borewells or overhead tanks, carries physical impurities that have nothing to do with dissolved salts or bacteria. Sand, rust flakes from old pipes, mud, and general sediment are mechanical problems, and they need a mechanical solution. That's exactly what a PP spun cartridge is for.

Every RO purifier — domestic or commercial — needs a pre filter cartridge like this one because the RO membrane itself is extremely fine and easily damaged. Without sediment filtration ahead of it, particles scratch the membrane surface, block its pores, and shorten its working life dramatically. A 10 inch PP filter is the industry-standard size for most household RO systems in India, which is why it's often called a universal RO filter cartridge.

How Does It Work?

The filtration process is straightforward, but it's worth understanding step by step:

1. Water enters the housing and flows around the outer surface of the cartridge.

2. Coarse particles get trapped first by the looser outer layers of spun polypropylene fiber.

3. Water moves inward through progressively denser layers of fiber.

4. Fine particles down to 5 microns are captured as water works toward the cartridge's hollow core.

5. Filtered water exits through the core and moves on to the next stage — typically a carbon filter or the RO membrane itself.

Because the filtration happens gradually across the depth of the cartridge (not just on the surface), the filter has a high dirt holding capacity. It doesn't clog instantly the way a simple screen filter would; it fills up gradually from the outside in, which means longer service life between replacements.

Key Features

• 5 micron filtration rating — fine enough to remove sand, silt, rust particles, and visible suspended solids while maintaining good water flow.

• Melt blown / spun polypropylene construction — creates a graded density structure for depth filtration rather than surface-only trapping.

• 10 inch standard length — fits standard housings used across most domestic and commercial RO systems in India.

• High dirt holding capacity — the layered design means the filter can absorb more sediment before pressure drop becomes an issue.

• No chemical treatment — made purely from polypropylene, safe for drinking water pre-filtration with no leaching of odor or taste.

• Universal compatibility — works with most standard 10 inch cartridge filter housings, regardless of purifier brand.

• Lightweight and easy to handle — simple to install or replace without tools in most housings.

Benefits

Better water quality. Removing sediment before the water reaches later stages means cleaner-tasting, clearer drinking water at the tap.

Membrane protection. The RO membrane is the most expensive part of your purifier. A good pre filter cartridge absorbs the physical wear that would otherwise fall on the membrane.

Longer RO life. With less sediment reaching downstream components, RO systems run into fewer blockages and last longer between major services.

Lower maintenance cost. Replacing a ?100–?300 cartridge every few months is far cheaper than replacing a damaged RO membrane.

Higher flow rate. A clean, properly sized sediment filter keeps water moving efficiently, instead of forcing your pump or purifier to fight against a clogged system.

Easy installation. No special tools or plumbing knowledge needed — it fits directly into a standard 10 inch cartridge housing.

Universal compatibility. As a standard-size cartridge, it works as a drop-in RO replacement filter across many purifier brands and models.

Applications

• Homes and apartments — the most common use case, protecting kitchen RO purifiers from tank or municipal water sediment.

• Restaurants and hotels — higher water usage means more sediment load; regular cartridge changes keep service consistent.

• Schools and hospitals — where consistent, clean drinking water access is essential and downtime isn't an option.

• Commercial RO plants — used as a pre-filtration stage ahead of higher-capacity membranes.

• Industrial pre-filtration — protecting pumps, valves, and downstream equipment from abrasive particles.

• Borewell water systems — borewell water often carries high sediment and mineral content, making pre-filtration especially important.

• Municipal water connections — even treated municipal water can carry sediment from aging pipelines.

• Tanker-supplied water — water stored and transported in tankers often picks up rust and sediment along the way.
