How to identify your Crystal Quest replacement filter
Match the system label and part number before buying a replacement cartridge or membrane.

Record the system and component labels
Find the model or SKU on the system label, documentation or order receipt. Photograph the label and note the part numbers of the components you need. Use the installation manual to identify each stage in a multi-stage system.
Match fit and function
Ask the merchant to confirm the replacement part for your exact configuration. Check the cartridge or membrane number, dimensions, end fittings and intended position. Similar-looking parts may be used for different stages.
Use the schedule for your model
Check the manual for the replacement interval, rated capacity and any operating conditions that change the schedule. Save a record of what you replaced and when. Ask the manufacturer if you cannot identify the part or procedure confidently.
Treat a SKU match as a reference, not a complete fit check
The replacement finder separates manufacturer-listed part references from ambiguous or unresolved matches. A part can be optional or used only in one configuration. A shared SKU can also occur on multiple listings with different fittings. Confirm the system version, stage, dimensions and connection before buying.
Check single cartridges and packs separately
The single shower cartridge is listed as CQE-RC-04045, while single Bath Ball replacement is CQE-RC-04052. Multipacks have different SKUs. SMART and carbon-block cartridges also have size and package choices, so the lowest price on a product listing may not describe the item in your system.
