20 Inch Big Blue PP Sediment Filter – 1 Micron Fine Particle Removal

The 20 inch Big Blue polypropylene sediment filter (1 micron) is a melt-blown depth cartridge designed for superior sediment removal in residential, commercial, and industrial water filtration systems. Constructed from 100 % polypropylene (PP) media, this filter effectively captures extremely fine particles such as sand, silt, rust, and other suspended solids down to 1 micron, preventing clogging and extending the life of downstream filters. Its Big Blue (4.5″ diameter) format ensures higher dirt-holding capacity and longer service life compared with standard cartridges. Replace every 4–12 months depending on water quality and flow. Compatible with all standard 20″ BB housings and ideal as pre-filtration for reverse osmosis, softeners, and RO/UV systems.

Sizing Guide

Whole House Filtration: 20″ Big Blue preferred for high flow and longer service life.
Micron Selection:
· 1 micron: Fine sediment, high clarity requirement.
· 5–10 micron: General pre-filtration with less pressure drop.
· Lowers flow? If pressure drop is significant, consider pre-filters (e.g., 5 micron first).

Timing Recommendations

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

Pros & Cons

✔ Pros

High fine particulate removal: Captures particles as small as 1 micron.
Fits standard Big Blue housings: Easy drop-in replacement.
Good chemical resistance: Polypropylene resists many contaminants.
Longer service life: Deep-depth melt-blown design for greater dirt capacity.

✘ Cons

Does not remove dissolved contaminants: Not effective for chlorine, odors, or heavy metals.
May reduce flow at heavy loads: Higher resistance as sediment builds.
Requires periodic replacement: Frequency depends on sediment load.

FAQ's

1: What size particles does a 1 micron filter remove?

It captures solid particles larger than ~1 micron such as fine silt, rust, and sand. It does not remove dissolved chemicals or microorganisms by itself.

2: How often should this cartridge be replaced?

Depending on water quality and usage, typically every 4–12 months. High sediment water may require more frequent changes.

3: Is this filter compatible with my system?

Yes — it is compatible with standard 20 inch Big Blue (BB) housings used in whole-house and RO systems.

4: Can this filter remove bacteria or viruses?

No. A sediment filter only removes particulates. For bacteria/virus removal, use ultrafiltration or UV systems

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.
