PurePlus Pro Whole House String Wound Sediment Filter

Sediment is one of the most common water-quality issues in homes, especially those using well water. Sand, rust, scale particles, and other suspended solids can make water look cloudy and can gradually affect faucets, fixtures, and appliances.
A whole house string wound sediment filter provides a practical way to capture these particles before water reaches the rest of the home. The new PUREPLUS Pro Whole House String Wound Sediment Filter is designed for fine sediment filtration while providing high dirt-holding capacity and a longer service life than conventional sediment filters.
What Is a String Wound Sediment Filter?
A string wound filter cartridge is made by wrapping continuous polypropylene fibers around a central core. The tightly wound structure creates a depth-filtration path that allows water to pass through while trapping suspended particles throughout the filter media.
Unlike a simple surface filter that mainly collects debris on the outer layer, the string wound structure captures particles at different depths of the cartridge. This makes it particularly useful for water containing sand, rust, scale particles, and fine sediment.
What Does a Whole House String Wound Sediment Filter Remove?
The primary purpose of a string wound sediment filter is particle and sediment reduction.
Depending on the filter’s micron rating, it can capture particles such as:
- Sand
- Rust
- Scale particles
- Fine sediment
- Suspended particles
- Some visible color-causing particles
A sediment filter is generally used as a pre-filter. It does not replace filtration technologies specifically designed for dissolved contaminants such as chlorine, certain heavy metals, or other chemicals.
Why Use a String Wound Filter for Well Water?
Well water can contain naturally occurring sediment that enters the water supply from the groundwater source or well system. Sand, silt, rust, and other particles can become noticeable at faucets and may accumulate in plumbing and appliances.
A whole house string wound sediment filter can be installed at the point where water enters the home to help capture these particles before they travel throughout the plumbing system.
For homes with well water, a 5-micron sediment filter can be a practical choice when fine sediment is the primary concern. The appropriate micron rating still depends on the actual water conditions and the amount of sediment present.
PUREPLUS Pro Whole House String Wound Sediment Filter
The PUREPLUS Pro Whole House String Wound Sediment Filter is designed for homes that need reliable whole-house sediment filtration, particularly well-water applications.
The cartridge is made from durable polypropylene rope wrapped around a polypropylene core. Its deep-filtration structure is designed to capture sediment throughout the filter media rather than relying only on the outer surface.
5-Micron Fine Sediment Filtration
The PUREPLUS Pro uses a 5-micron filtration rating to target fine sediment, sand, rust, and scale particles.
Its dense honeycomb-style structure is designed with a denser inner layer and more open outer layer, creating a deep-bed filtration path with strong dirt-holding capacity.
According to the product specifications, the filter can reduce up to 99% of sediment, sand, rust, and color.
Designed to Help Prevent the Growth of Harmful Contaminants
The PUREPLUS Pro filter is engineered to help prevent the growth of harmful contaminants within the cartridge, supporting consistent filtration performance throughout its service life.
This design helps maintain reliable filtration from initial installation through replacement, helping provide clearer water throughout the home.
Longer Service Life
The deep-filtration construction provides a larger area for capturing sediment. According to the product specifications, the PUREPLUS Pro can provide up to 30% longer service life than common sediment filters.
The expected filter life is approximately 3–6 months or up to 13,000 gallons, depending on water quality and household usage.
Homes with heavier sediment loads may need to replace the cartridge more frequently.
2.5 GPM Flow Rate
The filter provides a flow rate of approximately 2.5 GPM, making it suitable for whole-house sediment pre-filtration while balancing filtration performance and water flow.
Actual flow can vary depending on water pressure, filter housing, plumbing, and the amount of sediment accumulated in the cartridge.
Material and Certification
The PUREPLUS Pro Whole House String Wound Sediment Filter uses food-grade polypropylene microfiber.
The material meets European EC 1935/2004 requirements and is also described as BPA-free, REACH compliant, and Australia WaterMark recognized.
These material-related standards and certifications provide additional information about the materials used in the cartridge.
How Does a String Wound Filter Work?
Water enters the outer portion of the cartridge and travels through the layers of tightly wound polypropylene fibers.
As water moves through the filter:
Larger particles are captured closer to the outside of the cartridge.
Smaller particles can travel deeper into the filter media before becoming trapped.
This depth-filtration process allows the cartridge to hold a significant amount of sediment while continuing to allow water to flow through.
As sediment accumulates, water flow may gradually decrease. This is one indication that the cartridge may need to be replaced.
How Often Should You Replace a Whole House String Wound Filter?
There is no universal replacement schedule because filter life depends heavily on incoming water quality.
For the PUREPLUS Pro, the expected service life is approximately 3–6 months or 13,000 gallons, depending on usage and water conditions.
You should consider replacing the cartridge when:
- Water flow noticeably decreases
- The cartridge becomes heavily loaded with sediment
- Water quality or appearance changes
- The recommended service life has been reached
Homes with well water containing high levels of sand or sediment may need more frequent replacement.
Conclusion
A whole house string wound sediment filter can help reduce sand, rust, scale, and fine sediment before they enter your home’s plumbing system. The new PUREPLUS Pro Whole House String Wound Sediment Filter combines 5-micron depth filtration, a high dirt-holding structure, and polypropylene filter media for reliable whole-house sediment filtration.
For homes with well water or persistent sediment problems, choosing the right micron rating and replacing the cartridge according to actual water conditions can help maintain consistent water flow and clearer water throughout the home.
