Membrane Solutions 5-Micron String Wound Filter for Well Water
Designed as a 5-micron string-wound sediment cartridge, this universal 10×2.5-inch filter is suited as a prefilter for whole-house systems and RO units. Constructed from food-grade polypropylene, it is lead- and BPA-free, non-toxic, and odorless, reducing the risk of leaching into water. Its four-times dirt-holding capacity and increased flow rate help extend service life in feedwater with substantial sediment. The 10×2.5-inch universal size fits most standard housings, making it a versatile choice for well-water setups.
PUREPLUS 5-Micron Pleated Sediment Filter for Well Water
The PUREPLUS 5-micron pleated sediment filter provides a larger filtration area, improving efficiency while maintaining a strong flow. Made from food-grade material that meets EC1935-2004 regulations and BPA-free certified, the filter helps reduce sediment, sand, rust, and color. Its pleated design uses 3D weaving technology to capture more impurities without restricting water pressure. With a typical capacity around 30,000 gallons, it is recommended for replacement every 3–6 months for most households, depending on water quality and usage.
PUREPLUS 5-Micron Sediment and Carbon Filter Replacement
This filter combines sediment reduction with activated carbon to improve taste and color while removing up to 99% of sediment, sand, rust, and color. It uses food-grade materials and meets EC1935-2004 regulations, with BPA-free certification. It is designed for GE FXHTC, GXWH40L, GXWH35F, GNWH38S and similar housings, typically delivering up to 30,000 gallons of filtered water. Note: For well water, performance may vary; consider a product targeted to well water if sediment is exceptionally high. Pack includes two filters for easier replacement planning.
PUREPLUS 5-Micron String Wound Filter 10×4.5 Inch
Designed specifically for well-water filtration, this 5-micron string-wound cartridge uses a dense honeycomb structure and 3D weaving technology to capture more dirt while maintaining steady flow. It is made from food-grade polypropylene, BPA-free, and EC1935-compliant, with a typical lifespan around 30,000 gallons, depending on water quality. The 10×4.5-inch size fits most standard housings and is available in a 2-pack for convenient replacement scheduling. Expect strong sediment control with good flow for homes relying on well water.
PUREPLUS 1-Stage Well Water Filter 10×4.5″
This 1-stage system provides comprehensive well-water filtration by removing sediment, rust, and some heavy metals, delivering crystal-clear water to every tap. The unit is designed for 10×4.5″ universal housings and emphasizes durability and long service life under well-water pressures. It offers a high flow rate to maintain normal household water pressure during filtration, reducing the need for repeated filter changes. However, for heavily contaminated sources or high iron/manganese, consider upgrading to a multi-stage system with a dedicated iron- and manganese-reducing cartridge.
Buying Guide
Choosing the right cartridge for well water involves balancing sediment control, taste improvement, and system compatibility. Consider these factors to tailor a setup to your home:
- Water source and contaminants: Test your well water to identify sediment levels, iron, manganese, and taste/color issues. This informs whether you prioritize sediment-only filtration or a carbon-infused cartridge for taste improvement and chemical reduction.
- Micron rating: A 5-micron filter captures many common sediments without overly restricting flow. A 1- to 3-micron option provides finer filtration but may require more frequent replacements in sediment-heavy water.
- Filter type and material: String-wound and pleated filters excel at sediment removal; carbon-infused cartridges help with taste and odor. Food-grade polypropylene and BPA-free certification are common quality indicators.
- Housing compatibility: Most 10-inch housings are standard; verify the exact size (10×2.5″ vs 10×4.5″) and the housing thread type (usually 1″ NPT).
- Certifications and safety: Look for EC1935-2004 compliance, REACH, BPA-free, and third-party testing (NSF/ANSI) where possible for assurance on materials and performance.
- Flow rate and capacity: Check GPM rating and estimated gallons until replacement. Well-water setups may vary; 30,000 gallons is common in the products above, with replacement every 3–6 months depending on usage and water quality.
- Replacement schedule and maintenance: Multi-pack options save on replacement labor and ensure you have cartridges on hand. Documented replacement intervals help maintain filtration effectiveness over time.
- Well-water specifics: If your water contains high iron or manganese, consider a dedicated reduction stage or a multi-stage system designed for iron/manganese removal.
- Cost and durability: Higher-quality materials and multi-pack options can reduce long-term costs. Consider warranty, availability of replacements, and overall system compatibility.
Across well-water scenarios, a well-chosen 5-micron cartridge paired with a compatible 10-inch housing delivers robust sediment control with reasonable flow. When taste and odor are concerns, a carbon-inclusive cartridge can complement sediment filtration. For homes facing iron or manganese challenges, a staged approach with a dedicated reduction cartridge may be warranted. Always confirm compatibility with your existing filtration system and, if in doubt, consult a filtration professional to optimize performance for your specific well-water profile.
