20 Inch Big Blue PP Sediment Filter – 5 Micron Sediment Filtration

The 20 inch Big Blue PP Sediment Filter – 5 Micron is a melt-blown depth cartridge constructed from 100 % polypropylene designed for effective removal of suspended solids in water systems. With a nominal 5 micron rating, this filter captures larger particles such as sand, rust, silt, and dirt, extending the life of downstream filtration components like carbon filters and reverse osmosis membranes. Its Big Blue (4.5″ diameter) format provides high dirt-holding capacity and longer service life compared to smaller cartridges. Ideal for whole-house pre-filtration, municipal supply conditioning, well water filtration, and commercial systems. Compatible with all standard 20″ Big Blue housings.

Sizing Guide

Whole House Filtration: 20″ Big Blue is recommended for higher flow and longer life compared to standard 10″ cartridges.
Micron Selection:
• 5 micron: Ideal as primary sediment stage when water has moderately high particulate levels.
• 1 micron: For finer sediment removal (less flow, more frequent changes).
• 10 micron: For very coarse sediment with minimal restriction.

Timing Recommendations

Water Condition	Recommended Change Interval
Light sediment	~9–12 months
Moderate sediment	~6–9 months
Heavy sediment	~4–6 months

Pros & Cons

✔ Pros

High flow capacity: Big Blue housing and 5 micron rating allow better flow performance.
Reduces load on downstream filters: Captures coarser particles before carbon or RO stages.
Long lifespan: Deep-depth melt-blown design holds more dirt before change is required.
Compatibility: Fits all standard 20″ Big Blue housings for easy replacement.

✘ Cons

Not fine filtration: Does not remove very fine sediment <5 micron.
Does not remove chemicals or microbes: Requires additional filtration stages for full purification.
Pressure drop with heavy load: May slightly reduce pressure when heavily loaded.

FAQ's

1: What does 5 micron mean?

It means the filter captures particles around 5 micrometers and larger, ideal for sand, rust, and sediment.

2: How often should this filter be replaced?

Typically every 6–12 months, depending on water quality and sediment levels.

3: Is this compatible with my water system?

Yes — if your system uses a standard 20″ Big Blue housing, this cartridge fits directly.

4: Will this remove bacteria or chlorine?

No — sediment filters only remove solid particulate matter. For microbes or chemicals, add appropriate media (e.g., carbon, UV, RO)

5. What are Big Blue filter cartridges?

Big Blue filter cartridges are large‑capacity water filters designed for whole‑house and commercial water filtration systems. They fit Big Blue housings and effectively remove sediments, chlorine, rust, and other impurities from your water supply.

6. What sizes of Big Blue cartridges are available?

Big Blue cartridges typically come in standard sizes such as 20‑inch and 10‑inch lengths, with different micron ratings to suit your water quality needs. Check product details to choose the correct size for your system.

7. What micron ratings do Big Blue cartridges come in?

Big Blue cartridges are available in a range of micron ratings — from coarse filters (e.g., 5 µm) for sediment removal to finer filters (e.g., 1 µm) for finer particulates. Choose the rating based on your water quality and filtration requirements.

8. What do Big Blue cartridges filter out?

Depending on the cartridge type, Big Blue filters can remove:

Sediments like sand, silt, and rust
Chlorine and chemical tastes/odours (carbon cartridges)
Scale and particulates that affect appliances and plumbing

9. How do I install a Big Blue filter cartridge?

Turn off the water supply to the filter housing.
Relieve pressure by opening a nearby tap.
Remove the housing and old cartridge.
Insert the new Big Blue cartridge, ensuring correct orientation.
Reassemble and turn the water back on.
Always follow the installation instructions provided with your filter housing.

10. Can Big Blue cartridges improve water taste and odour?

Yes — activated carbon Big Blue cartridges are specifically designed to reduce chlorine taste and odour, giving you cleaner and better‑tasting water.

11. Are Big Blue cartridges compatible with my filter system?

Big Blue cartridges fit standard Big Blue housings (typically 4.5” diameter). Check your housing size and cartridge length before purchasing to ensure compatibility.
