PUREPLUS 5 Micron 4.5 in x 20 in Whole House Sediment Filter - Well

In this review the PUREPLUS 5 micron 4.5 in x 20 in whole house string wound sediment filter is evaluated for households using well water and standard 20 x 4.5 heavy duty housings. The bottom line: it is a practical replacement cartridge for anyone seeking reliable sediment removal without sacrificing flow. Used as a replacement for common 20 in filter models, the cartridge targets sand, rust and color with up to 99% reduction claimed and stands out for a dense inner structure that increases dirt holding capacity and service life.

Key Features

• Compatibility: Fits any standard 20 x 4.5 in heavy duty filter housing and many common models so installation is straightforward for existing systems.
• Material Certification: Made from food grade material that meets European EC1935-2004 and other recognized standards, giving confidence for potable water use.
• 5 Micron Filtration: The thin dense honeycomb design provides accurate 5 micron filtration to capture fine particles and reduce visible sediment and discoloration.
• High Dirt Holding Capacity: A dense inside and sparse outside string wound design holds more sediment for longer life between changes, reducing maintenance frequency.
• Extended Service Life: Rated for up to 30,000 gallons depending on water quality, which typically translates to 3 to 6 months of household use.
• Good Flow Rate: Engineered to maintain flow up to about 2.5 GPM so water pressure is preserved while filtering.

Who It's For

This filter is best for homeowners with well water or municipal supplies that see visible sand, rust or color issues, and for anyone who already owns a standard 20 x 4.5 in filter housing from the listed compatible models. It is a straightforward replacement option for maintenance-minded users who want certified, food grade materials and a longer service life.

Those who should look elsewhere include users needing submicron or specialty chemical removal, or systems requiring higher flow rates than the cartridge design supports; this is a sediment filter, not a comprehensive chemical or microbial treatment device.

Pros & Cons

Pros

• Effectively captures sediment, sand and rust with a reliable 5 micron rating.
• Certified food grade materials provide reassurance for drinking water use.
• Longer service life and strong dirt holding capacity reduce replacement frequency.
• Maintains household water pressure thanks to an engineered flow rate near 2.5 GPM.

Cons

• Not designed to remove chemicals, bacteria or viruses, so additional treatment may be needed.
• Size may be a concern for users with nonstandard housings, as some customers reported mixed reactions to fit and dimensions.
