Collection: Water Filter Cartridges | Replacement Cartridges for Clean & Pure Water

Find the right replacement cartridge (without the guesswork)

Shopping for replacement water filter cartridges should be simple. This collection is designed for Australian homes and workplaces that want an easy way to match the correct cartridge by system type, size and (where available) part number. If you’re replacing a cartridge to bring back better flow, taste or day-to-day performance, start here and narrow down from your current setup.

Key benefits

• Match by what matters: system type, cartridge size, connection style and part number.
• Options for common setups: from multi-stage replacements through to standard housing cartridges and selected whole-house styles.
• Less risk of ordering the wrong fit: use your label details (or send a photo) and we’ll help you confirm compatibility.
• Better day-to-day use: timely replacements can help maintain flow and the “fresh” feel of filtered water (depending on cartridge type).

How it works

Different cartridges do different jobs. Some are designed to capture sediment (like sand or fine particles), while others use carbon or specialised media that many people choose for taste and odour improvement. Because performance depends on the cartridge type and your water conditions, the safest approach is to select the replacement recommended for your exact system and stage order.

What you get

• Replacement cartridges and parts for a range of filtration setups (as listed in this collection).
• Multi-pack options for some systems, where available.
• System-specific formats such as standard housings, quick-change styles, inline filters and specialty components (check each product page for details).

Maintenance & replacement tips

Use a simple checklist:

• Step 1: Identify your system type (benchtop/countertop, undersink, whole house, RO).
• Step 2: Match the cartridge size shown on your current filter (for example, “10" x 2.5"” on many standard housings).
• Step 3: Confirm connection style (standard sump housing vs quick-change vs inline).
• Step 4: Match any part number on the label (or your previous order confirmation).

Replacement timing: schedules vary by cartridge type and water conditions. For AWF 7 and 8 stage filters, see the care notes in our guide. Always follow the instructions for your exact model and stage order.

FAQs

• How do I know which replacement cartridge fits my system?
  Check your current cartridge label/part number, housing size, and 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.
• Are these cartridges for benchtop, undersink, and whole-house systems?
  This collection includes a mix of replacements across several system types. For faster browsing, use the “Learn more” links to jump to system-specific collections.
• How often should I replace my cartridges?
  It depends on the cartridge type, your water conditions and usage. Always follow the instructions for your model and stage order. If you have an AWF 7/8 stage setup, refer to our replacement guide for general care notes.
• My water flow has slowed—does that mean it’s time to change the filter?
  A drop in flow can be a sign the cartridge is loaded with sediment or needs cleaning/replacement (depending on the cartridge type). Check your product instructions and replace if you’re overdue.
• Do I need tools to change a cartridge?
  Some standard housings require a spanner/wrench, while many quick-change cartridges don’t. For plumbed-in systems, turn off the water supply first and follow the instructions for your unit.
• Can I swap in a different cartridge type “to upgrade” my system?
  Only if your system is designed for it. Multi-stage systems rely on the correct cartridge types and order—use the recommended replacements for your model.
