Frequently asked questions
Will these filters fit my pitcher or dispenser?
ZERO FILTER ONLINE® cartridges are made for round 5-stage pitchers and dispensers that use a twist-in cartridge. Compare your current cartridge with our product photos before ordering. Not sure? Email info@zerofilterstore.com and we will help.
What does a 5-stage cartridge do?
Water passes through a coarse screen, a distributor, activated carbon, ion-exchange resin and a fine screen. Together these layers help reduce sediment, chlorine taste and odour, and dissolved solids. Results depend on your local tap water.
When should I replace my filter?
Filter life depends on how much water you filter and on your tap water. Check your filtered water with a TDS meter: when the reading starts to rise, or you notice a change in taste, it is time for a new cartridge.
Do I need to soak or flush a new filter?
No soaking or flushing is needed. Install the cartridge following your pitcher or dispenser instructions, fill the reservoir with cold tap water and let it filter through.
Which pack size should I choose?
Every pack contains the same 5-stage cartridge. Choose by how often you change filters. The price per filter for each pack is shown on the product page.
