20μ Sediment Filter 20 inches BB For Dirt Removal
The AMPAC USA 20μ Sediment Filter is a jumbo Big Blue cartridge (4.5" x 20") built to remove dirt, rust, sand, silt, and other suspended solids from your water supply. Its 20-micron nominal rating captures particles down to 20 micrometers, delivering a real improvement in clarity without excessively restricting water flow.
- Fits standard Big Blue 4.5" x 20" filter housings
- Nominal 20-micron rating for effective particulate removal
- Traps dirt, rust, sand, silt, and other suspended solids
- Melt-blown polypropylene media, free of wetting agents, solvents, antistatic agents, or binders
- High flow rate and extended dirt-holding capacity
This filter excels as a whole-house pre-filtration stage, acting as the first line of defense against particulate matter before it reaches more sensitive filters or appliances. That protection extends the life of downstream carbon blocks and reverse osmosis membranes while shielding plumbing and water-using appliances from abrasive sediment damage. It's equally effective as a pre-treatment stage ahead of commercial reverse osmosis systems, where clean feed water is essential to protecting membrane integrity and maintaining system efficiency.
Because the filter media is manufactured without wetting agents, solvents, antistatic agents, or binders, it's well suited to drinking water pre-treatment — no unwanted chemicals leach into the water during filtration. The Big Blue format's larger diameter and length give it a higher flow rate and greater dirt-holding capacity than smaller cartridges, so it can process more water before it needs replacing.
Every AMPAC USA 20μ Sediment Filter is manufactured to consistent standards for micron rating, structural integrity, and material purity, giving residential and commercial users alike a dependable first-stage filter for cleaner water and better-protected downstream equipment.

Frequently Asked Questions
What does the 20μ Sediment Filter remove from water?
It removes particulate matter such as dirt, rust, sand, silt, and other suspended solids down to 20 microns in size, improving water clarity and protecting downstream equipment.
What size filter housing does this cartridge fit?
It's a jumbo Big Blue cartridge sized 4.5 inches in diameter by 20 inches long, designed to fit standard Big Blue filter housings.
Is this filter safe to use ahead of drinking water systems?
Yes. It's made from melt-blown polypropylene with no wetting agents, solvents, antistatic agents, or binders, so it removes contaminants without introducing new ones.
Can this filter be used as pre-treatment for a commercial reverse osmosis system?
Yes. It's commonly used as a pre-filtration stage ahead of commercial RO systems, protecting membranes from sediment and helping maintain performance and longevity.
What's the benefit of the Big Blue format over a standard-size cartridge?
The larger 4.5" x 20" format supports higher flow rates and greater dirt-holding capacity, so the filter can process more water before it needs to be replaced.
