Premium Water Filter Cartridge Replacements

Key benefits

• Match the right fit faster: filter by common sizes (including 10" and 20") and narrow by micron rating.
• Shop by your setup: options across benchtop, under-sink, whole house and RO-style replacements.
• Less chance of ordering the wrong item: follow the simple 60-second checklist below before you buy.
• Help when you need it: if you're uncertain, photos of the label + housing make matching much easier.

How it works

Different cartridges do different jobs. Some are chosen for sediment (particle) capture, others are chosen for taste/odour improvement, and some are selected by a specific micron rating or media type. The safest approach is to replace like-for-like based on your exact system model and stage order. Always check the product page details for the cartridge format and compatibility notes.

Find your match in 60 seconds

1. Read your current label: note the series/stage name and any part number shown.
2. Confirm the size: use the on-page filters to match your current cartridge length/diameter (common sizes here include 10" x 2.5", 10" x 4.5", and 20" x 2.5").
3. Choose the right "job": match sediment vs carbon vs other media, plus the micron rating (if applicable).
4. Check the format: standard housing cartridges differ from other styles — confirm what your system takes before ordering.

Installation & maintenance

Replacement timing varies depending on cartridge type, your local water conditions and how much water you use. A drop in flow or a change in taste or odour can be a prompt to check your cartridge — see our guide on the 5 signs you need to replace your water filter if you're not sure it's time yet. If your setup is a multi-stage system, follow the recommended stage order and care notes for your exact model.

FAQs

• How do I know which replacement cartridge fits my system?
  Match the label/part number (if available), the cartridge size, and the cartridge format/connection style. If you're unsure, send a clear photo of the label and housing via our contact page and we'll help you narrow it down.
• What's the difference between sediment and carbon cartridges?
  Sediment cartridges are chosen for particle capture, while carbon-style cartridges are commonly chosen for taste and odour improvement. Always replace what your stage order requires for your exact system.
• What do micron ratings mean (for example 0.5 vs 20 micron)?
  Micron rating is a way to compare filtration fineness. Use the on-page filters to select the rating that matches your system stage and housing.
• My water flow has slowed — does that mean I need a new filter?
  Slower flow can be a sign a cartridge is loaded (especially sediment stages). Check your product instructions and replace if you're overdue — our step-by-step walkthrough on how to replace a water filter cartridge covers the process if you'd like a hand.
• Are these cartridges for benchtop, under-sink and whole-house systems?
  This collection includes replacements across several system types. For faster browsing, use the system links in the "Learn more" section above.
