1 Micron Polyspun Sediment Water Filter Cartridge | 20” x 4.5” Whole House Replacement Filter

The 1 Micron Polyspun Sediment Water Filter Cartridge (20” x 4.5”) is designed for high-performance whole-house water filtration systems, including Big Blue–style housings. This filter is the first line of defence in your system, removing fine sediment before it reaches carbon filters, appliances, plumbing fixtures, and tapware.

Manufactured from high-density polypropylene, this depth-filtration cartridge effectively captures dirt, sand, silt, rust, scale, and other suspended particles down to 1 micron, improving water clarity while extending the service life of downstream filters.

Its graded, grooved polyspun structure increases surface area and dirt-holding capacity, allowing for consistent flow rates and reduced pressure drop across the filter. This makes it ideal for residential homes, offices, and light commercial applications where water quality and system protection matter.

Key Features & Benefits

  • 1 Micron Filtration – Removes fine sediment, dust, rust, and particulate matter for noticeably clearer water

  • Polyspun Depth Filter Design – High dirt-holding capacity for longer service intervals

  • Grooved Surface Construction – Maximises surface area and improves flow efficiency

  • Universal 20” x 4.5” Size – Compatible with most Big Blue and standard whole-house filter housings

  • Food-Grade, BPA-Free Polypropylene – Safe for potable water applications

  • Protects Downstream Filters & Appliances – Reduces clogging and premature filter failure

This 20” x 4.5” 1 micron sediment filter is an essential component for maintaining performance, water clarity, and system longevity in any whole-house filtration setup.

Where This Filter Sits in the System

  • Stage 1 of a whole-house system

  • Removes sediment, dirt, rust, algae, turbidity, and other particulate contaminants. Protects downstream carbon / PFAS filters.

  • Not designed to remove chlorine, PFAS, or chemicals

  • Most homes should replace this filter every 6–12 months, depending on incoming water quality and household usage. Properties with high sediment levels, visible discoloration, or pressure drop may require more frequent replacement.

  • No. A 1 micron polyspun sediment filter is ideal as a first-stage filter in whole-house systems. It removes fine sediment while still maintaining good flow, especially when used in a 20” x 4.5” Big Blue housing.

  • When clean, pressure drop is minimal and unnoticeable. Any noticeable reduction in pressure usually indicates the filter is doing its job and becoming loaded with sediment, which is a sign it’s time for replacement.

  • No. This is a sediment-only filter designed to remove physical particles like rust, sand, and silt. It is intended to protect downstream filters such as carbon or PFAS filters, which handle chemical and contaminant removal.

  • This filter fits all Pure₂O whole-house filtration systems. It also will fit all standard 20” x 4.5” Big Blue–style housings. It is not compatible with slimline or 10” filter housings. If you’re unsure, check your housing size or contact us before purchasing.

  • This filter is typically installed at Stage 1, immediately after the mains water supply. Its role is to capture sediment before water reaches carbon, specialty media filters, appliances, and tapware.

  • Yes. The filter is made from food-grade, BPA-free polypropylene and is suitable for potable water applications when used in a Pure₂O Whole-House Water Filtration System, or another appropriately sized whole-house filtration system.

When to Replace

Replace approximately every 6–12 months, depending on incoming water quality and household water usage. Homes with high sediment loads may require more frequent replacement.

Typical Applications

  • Whole-house water filtration systems

  • Pre-filtration for carbon, PFAS, or specialty media filters

  • Residential, office, and light commercial installations

Compatibility Note

This cartridge suits standard 20” x 4.5” housings only. Not compatible with slimline 10” systems.
