Under Sink Water Filter Cartridge
Under-Sink Water Filter Cartridges – Reliable Replacement for Pure Flow
Your filter cartridge is the heart of your under-sink system—it captures impurities, improves taste, and safeguards water quality. Regular replacement (every 6–12 months or as per system guidelines) restores flow and filtering efficiency. Delayed changes may result in dull taste, slower water, or poorer filtration.
Types of Cartridges & What They Do
| Cartridge Type | Function & Benefits |
|---|---|
| Sediment Cartridges | Remove particles like rust, silt, or sand—protects downstream filters. Usually replaced every 6 months. |
| Carbon Block / GAC Filters | Reduce chlorine taste, odors, VOCs, and some chemical contaminants. Used in both single and multi-stage systems. |
| Reverse Osmosis (RO) Membranes | Advanced filtration—removes dissolved solids, heavy metals, and more; often part of 4–6 stage systems. |
| Specialty Filters | Address unique needs such as fluoride, heavy metals, or microbial reduction (e.g. KDF, ceramic, ultrafiltration). |
Choosing the Right Replacement Cartridge
-
Identify Your Filter System and Size
Cartridges come for specific systems or standard housing sizes—10″ or 9″ models, among others. -
Match Cartridge Type to Filtration Needs
Start with sediment if water is murky, or carbon for improved taste. Choose RO for in-depth purification. -
Check Certifications
Look for NSF, WQA, or IAPMO marks to ensure performance and safety. -
Consider Replacement Frequency
Sediment filters may need changing every 6 months, carbon and RO elements between 6–12 months, depending on use and water quality. -
Confirm Flow Rate & Capacity Needs
Ensure the cartridge supports your demands—high-flow setups (e.g., dishwashers) may require larger or faster filters.
