PUREPLUS 5 Micron 10 x 4.5 Whole House String Wound Sedment Filter

In this review the PUREPLUS 5 micron 10 x 4.5 string wound cartridge is evaluated as a replacement whole house sediment filter for well water systems; it is best for homeowners who need reliable removal of sand, rust and visible particles without stripping beneficial minerals. The bottom line: this cartridge is a practical, cost-effective replacement that fits standard 10' x 4.5' housings and delivers strong dirt-holding capacity and long service life compared with basic paper options, making it a smart choice where sediment is the primary concern.

Key Features

• Certified Materials: Food grade construction meets European EC1935-2004, Australia Water Mark and REACH standards, and is BPA free to give confidence in material safety.
• High Filtration Accuracy: The 5 micron rating and thin dense honeycomb rope design capture fine sediment, sand and rust while maintaining flow for whole house use.
• Extended Service Life: Innovative structure gives about 30% longer life than common sediment filters and can handle up to 30,000 gallons depending on water quality.
• Good Flow Rate: Designed for a deep bed filtration function with a flow capability up to 2.5 GPM to keep household supply steady under typical conditions.
• Wide Compatibility: Fits standard 10 x 4.5 heavy duty housings and many common filter models so it is easy to drop into existing systems.
• Quality Control: Produced under ISO9001/14000 processes with pressure and water hammer testing to reduce risk of leaks or failures.

Who It's For

This cartridge is aimed at homeowners on well water or those with clearly visible sediment in their incoming supply who need a durable, low-cost replacement for whole house sediment housings. It suits people who prioritize material certifications and a filter that holds more dirt than paper cartridges.

Those looking to remove dissolved chemicals, soften water, or reduce TDS should look for specialized carbon, catalytic, or softening stages instead, since this is a sediment cartridge that does not lower TDS and is designed specifically to trap particulates rather than change water chemistry.

Pros & Cons

Pros

• Certified food grade materials and BPA free construction provide reassurance about safety.
• 5 micron string wound design removes sand, rust and color effectively and lasts longer than many basic filters.
• Easy to install in standard 10 x 4.5 housings and compatible with a wide range of common models.
• High dirt-holding capacity with a respectable flow rate for whole house use.

Cons

• Does not reduce TDS or remove dissolved contaminants, so additional stages are needed for chemical concerns.
• Service life depends heavily on local water quality, so frequent replacement may be required in very dirty wells.
