How to Find the Correct Replacement Cartridge for Your Crystal Quest System

Locate Compatibility Information

Crystal Quest provides multiple built-in resources to help you quickly identify the correct replacement cartridge for your system.

Use the options below to confirm the exact part number and size before ordering.

Filter Housing Labels (Fastest Method)

Many Crystal Quest systems include a specification label directly on the filter housing that lists:

• Compatible cartridge part numbers

• Cartridge size (2.5" or 4.5" diameter)

• Cartridge type or model

Check:

• The housing sump (white or blue bottom section)

• The side of the housing

• The mounting bracket or head

This is often the quickest way to verify compatibility without paperwork.

The Crystal Quest Website

Visit your system’s product page at crystalquest.com. Each listing includes:

• Parts & Components tab

• Direct links and SKU numbers for the correct replacement cartridges

Simply search your system model number or name to locate the correct replacements.

Account History

If you’ve ordered from Crystal Quest before, you can also use your order history to identify the exact system or cartridge you purchased:

Check Your Previous Order History (Most Accurate for Repeat Customers)

Log into your Crystal Quest account at account.crystalquest.com

Go to Account → Order History

Open the relevant order

Click the product name (or copy the product name/SKU)

Navigate to that product page and open the Parts & Components tab to view the correct replacement cartridges.

Tip: If you purchased multiple systems, match the item name in your order to the model name printed on your system housing label to confirm compatibility.

Product Packaging

Original packaging frequently lists:

• Replacement cartridge part/SKU numbers

• System specifications and dimensions

• Included components

If you still have your box or inserts, check the specifications panel or documentation for reference.

System Owner’s Manual

Your owner’s manual contains a list of:

• Compatible replacement cartridges

• Part numbers

• Recommended replacement intervals

• Maintenance instructions

If you’ve misplaced your printed copy, digital manuals are available on our website.
