Key benefits

• Less guesswork: choose replacements by part number (where listed), size, and connection style so you’re not buying blind.
• Keep your countertop setup running smoothly: timely cartridge changes help maintain day-to-day flow and water enjoyment.
• Options for popular countertop brands and formats: including Doulton-style ceramic/carbon cartridges and Omnipure options (see product listings for exact compatibility).
• Helpful support if you’re unsure: if you can’t match your cartridge confidently, send us a clear photo and we’ll help you identify the right replacement.

How it works

Countertop filtration is popular because it’s practical: no under-sink plumbing, easy access for cartridge changes, and a simple way to improve the everyday experience of your drinking water. Different cartridges use different media (for example, some combine ceramic and carbon). The best approach for most customers is to replace like-for-like—match your current cartridge label and fit type first, then confirm any extra details (such as size or mount thread) in the product listing.

What you get

• Single replacement cartridges for compatible countertop filter systems (product dependent).
• Fluoride-specific cartridge options (as labelled in the product title/description) for compatible setups.
• Multi-stage bundle packs for selected countertop systems (where listed), so you can refresh multiple stages at once.

Installation & maintenance

Before you order: check the label on your current cartridge and confirm (1) the part number/model, (2) the connection style, and (3) the cartridge size. If you’re unsure, our recommended shortcut is to send a clear photo of your cartridge and housing via our contact page and we’ll help confirm the best match.

When replacing: follow the instructions shown on your cartridge/system listing. As a general care step, many cartridges benefit from a brief rinse/flush to clear any harmless initial dust and prime the media (always follow the product instructions for your specific cartridge type). For ceramic-style filters, clean gently and avoid soap/detergent unless the product instructions explicitly say it’s suitable.

FAQs

• How do I know which countertop cartridge fits my system?
  Start with your current cartridge label: match the part number/model (where available) and the fitting type (for example, a threaded mount). Then confirm size and compatibility notes on the product listing.
• What if my cartridge label is worn or missing?
  Take a clear photo of the cartridge and the filter head/housing (including any threads or connection points) and send it via our contact page. We can help you narrow down the closest match.
• Do countertop cartridges need flushing before use?
  Often, yes. Many cartridges benefit from a brief rinse/flush to prime the media and clear harmless initial dust. Always follow the instructions on your specific cartridge listing.
• How do I clean a ceramic-style cartridge?
  Clean gently under running water using a soft sponge or non-abrasive pad. Avoid soap/detergent unless the product instructions explicitly state it’s suitable for that cartridge.
• My flow has slowed down—does that mean I need a new cartridge?
  Slow flow is a common sign the cartridge is loading up. If your cartridge type allows cleaning, try the recommended care steps first. If flow doesn’t improve, replacing the cartridge is usually the next step.
• Can I swap to a different cartridge type as an “upgrade”?
  Only if your system is designed for it. Changing media or cartridge format can affect flow and performance, so replacing like-for-like is the safest choice unless your system documentation recommends an alternative.
• What if I ordered the wrong cartridge?
  Contact us as soon as possible and we’ll help you work out the correct replacement and the best next step in line with our store policies.
