Replacement Internal Filter Cartridge – Hardware

Each cartridge acts as a two-stage filter by providing mechanical and chemical filtration. The dense foam outer layer removes dirt and particulates while inside, the activated carbon removes odor, organics and discoloration. The rigid frame ensures that water passes through the cartridge, and not around it, for optimal water filtration.

Dense foam mechanical filtration removes particles and debris
Activated carbon chemical filtration removes toxins, odors and discoloration
Replace approximately every 30 days for crystal clear water and proper filter operation
If water flow slows inside 30 days, rinse the debris off the cartridge and return to filter
Large Cartridge fits QuietFlow Internal Filter models AT30 (one) and AT 40 (two)
