⚡ At a Glance
- • Filtration Performance: Activated carbon plus a multi-layer structure reduces chlorine, heavy metals, odour, scale and sediment while retaining healthy minerals
- • Best for: Households using Waterdrop jugs or tank filtration systems who want affordable replacement cartridges
- • Not ideal for: Systems that fall outside the listed Waterdrop compatibility range or require OEM-only parts
NSF 42 certified activated carbon cartridges use multiple layers including nylon mesh, ion-exchange resin and non-woven cotton for deep filtration. Compatible with a wide range of Waterdrop jug and tank models and rated for around 200 gallons or eight weeks of use per cartridge.
Cleaner Drinking Water - Thanks to activated carbon and multi-layer filtration
Activated carbon adsorbs chlorine and organic compounds while a multi-layer structure (nylon mesh pre-filter, ion-exchange resin, activated carbon layer, non-woven cotton) traps sediment and exchanges ions to soften water. NSF 42 certification applies to the activated carbon element of the media.
Clearer flavour and reduced unpleasant tastes and smells make tap water more pleasant for drinking and cooking.
Simple Swap and Fit - With direct compatibility across Waterdrop jug and tank models
Cartridges are manufactured to match dimensions for models including WD-WFD-22, WD-WFD-40, WD-WFD-40-L, WD-PT-07, WD-PT-05, WD-PT-05-L, WD-PT-04, WD-PT-61 and WD-PT-72. Installation is a plug-in replacement that requires no tools.
Fast, tool-free cartridge changes keep downtime to a minimum and match the fit of original filters according to user feedback.
Longer Service Life - With roughly 200-gallon capacity and an eight-week recommendation
Each cartridge is rated to filter about 200 gallons of water or to be replaced approximately every eight weeks under typical household usage. Continuous filtration design supports sustained performance over that lifecycle.
Fewer changes per year reduce waste and upkeep, making cartridges a practical alternative to single-use bottles.
