The document lists various compatible consumables, including:

• Carbon Cartridges: Pleated carbon, granular carbon, and carbon block cartridges for chlorine taste and odor reduction, in micron ratings from 0.5 to 25.
• Specialty Cartridges: Such as an Oil Adsorbing cartridge.
• Sediment Cartridges: Polypropylene and cellulose polyester cartridges in various micron ratings from 1 to 75.
• Filter Bags: Polypropylene Felt bags in micron ratings from 1 to 800.

Note: The housing will not accept GAC 20BB, BBF1-20BB, WS-20BB, or CRFC-20BB cartridges.

See the official PDF for exact tabulated values for specific part numbers, materials, and micron ratings of cartridges and bags.
