20" x 4.5" Melt Blown Sediment Filter
The Hydronix SDC Series cartridge delivers consistent sediment removal in a proven melt blown design. Its larger filtration surface area translates to longer life and higher dirt-holding capacity compared to standard spun polypropylene filters. Engineered for 20" x 4.5" housings, this cartridge handles pre-filtration for reverse osmosis systems, well water applications, and whole house sediment control.
Why the Hydronix SDC Series Works
Melt Blown Construction
True depth filtration with graded density from outer to inner layers, capturing particles throughout the media for longer service intervals and superior dirt-holding capacity.
Multiple Micron Ratings
Available in 1, 5, and 20 micron options to match your application, from fine sediment polishing to heavy particulate removal in well water systems.
High Flow Capacity
4.5" diameter body provides ample surface area for commercial and whole house installations without excessive pressure drop during normal flow conditions.
Standard Sizing
Fits all standard 20" x 4.5" filter housings, making it a direct replacement for most sediment pre-filters in residential and commercial water treatment systems.
Pre-RO Filtration
Protects reverse osmosis membranes from sediment damage, extending membrane life and maintaining system performance in municipal and well water applications.
Economical Performance
Proven reliability without premium pricing, making it ideal for regular maintenance schedules in residential, commercial, and light industrial installations.
Where This Filter Fits
The Hydronix SDC Series is designed for any standard 20" x 4.5" filter housing and works across whole house systems, well water pre-treatment, commercial pre-filtration, and reverse osmosis system protection. Common applications include sediment removal upstream of carbon filters, pre-filtration for RO membranes, post-filtration after granular activated carbon (GAC) media tanks, and general particulate control in municipal or well water supplies. Choose 20 micron for heavy sediment, 5 micron for general pre-filtration, or 1 micron for fine polishing before membranes or sensitive equipment.
Hydronix filters are manufactured to consistent standards and backed by a reputation for reliable performance in water treatment applications.
