Empty Refillable Cartridge 10" x 2.5" Clear (EC-25975-C)
Empty Refillable Cartridge 10" x 2.5" Clear (EC-25975-C)
The Watts EC-25975-C gives you complete control over your filtration strategy. Fill this 10 inch x 2.5 inch clear cartridge with your choice of media—GAC, KDF, bone char, calcite, or custom blends—to target specific contaminants at precise ratios. The transparent shell lets you monitor media condition and flow patterns without disassembly.
Why Choose a Refillable Cartridge
Custom Media Blends
Load your preferred filtration media in any combination—mix catalytic carbon with phosphate, layer sediment over GAC, or create multi-stage media beds tailored to your water chemistry.
Clear Visibility
Transparent construction allows you to see media channeling, compaction, or exhaustion at a glance, making maintenance timing more accurate than opaque cartridges.
Reusable Shell
Replace only the filter media, not the entire cartridge housing. Reduces plastic waste and cost per cycle compared to sealed, single-use filters.
Standard Dimensions
10" x 2.5" form factor fits any standard filter housing with compatible sizing—drop-in replacement for most residential and light commercial systems.
Precision Control
Adjust media volume and density to fine-tune flow rate, contact time, and filtration efficiency based on your specific contaminant load and water demand.
Watts Quality
Manufactured by Watts Premier with durable, food-grade materials engineered for consistent performance across hundreds of refill cycles.
Fits Standard 10-Inch Housings
The Watts EC-25975-C (also listed as RC-C-975-50) works with any 10-inch standard filter housing that accepts 2.5-inch diameter cartridges. Ideal for DIY water treatment projects, specialty contaminant removal (arsenic, fluoride, heavy metals), aquarium and aquaponics systems, laboratory applications, and any scenario where pre-loaded cartridges don't address your exact filtration needs. Compatible with housings from Watts, Pentek, Culligan, GE, Whirlpool, and other brands using industry-standard dimensions.
Refillable cartridges from Watts give you the flexibility commercial filters can't match—fill once, refill indefinitely, and adapt your filtration as your water quality changes.
