Use the refrigerator model label, the old cartridge, and the appliance manual to confirm the exact replacement before ordering.
Start with the full refrigerator model number
Open the refrigerator and look for the appliance information label using the location suggested in the owner’s manual. Copy the model number exactly, including its final letters and any dash. A family name printed on a door or sales receipt may describe several configurations. The complete model code is the detail you will need when looking up the filter for your particular refrigerator.
Take a clear photograph if the label is small or hard to read. Keep the model number with the appliance paperwork. Save the serial number separately for service questions, and share it only when the manufacturer or service provider needs it. If you manage more than one refrigerator, identify which unit each note belongs to before comparing parts.
Locate the air filter in the manual
Find the documentation for the full model code. Look for the section on care, odor filtration, or replacement parts, and check whether that model uses a replaceable air cartridge. The manual can help you identify its location and the way the cover opens. A refrigerator may also have a separate water filter with a different part number and replacement procedure.
If the documentation covers several models, look for a chart or a model-specific note before using the part reference. Save the exact line and the page where it appears. If the manual describes a different cover than the one in your refrigerator, confirm the complete model code and ask the manufacturer before trying to remove a panel.
Read the cartridge markings where available
If a filter is already installed and the manual gives a removal method, follow that procedure so you can see the cartridge label. Photograph the front, edge, and any arrows or tabs. Write down the printed replacement code with the exact spelling and digits. Keep the used cartridge out of the way while you compare the information.
Use the old cartridge as one piece of evidence. Someone may have replaced it before, especially if the refrigerator was bought used. Compare its printed code with the manufacturer’s parts information for the appliance. If the old filter carries a different number, ask whether that code is an approved cross-reference before ordering it again.
Check the full filter family name and code
Look for the exact filter code in the replacement listing’s compatibility section. The current SEISSO listing is for Pure Air Ultra II and lists PAULTRA2 among the references. Use the appliance manual to confirm that reference for your refrigerator. Read the entire name carefully, since a shared brand name or the words Pure Air alone give you less information than a complete part number.
A listing may show several codes for an equivalent part. Record which code comes from your manual and which appears in the listing. Ask the seller to confirm the match if the page contains a code that resembles yours but differs by a digit, letter, or suffix. This is especially useful when two similar packages appear side by side in search results.
Use shape and dimensions as a second check
Compare the outline, thickness, retaining features, and orientation markings with the original cartridge or the diagram in the refrigerator manual. A photograph taken from above may hide an edge or tab that matters when you insert the filter. Check the side view if the seller provides one. Use those visual details alongside the written compatibility information.
If the measurements or the cartridge shape disagree with the part information, contact the seller with the model and part code. Ask about the specific item you plan to order. Once a cartridge arrives, compare it with the original or the diagram before installing it. Pause if the cover requires force or the part will not sit as illustrated.
Choose the pack after confirming the match
The current SEISSO Pure Air Ultra II listing offers three-pack and six-pack options. Check which option is selected and compare it with the number of refrigerators you are maintaining. If the appliances use different cartridges, keep their replacements labeled by model. This makes it easier to pick up the correct package when a filter is due.
Use the manufacturer’s care instructions for replacement timing, storage, and any filter reminder. Record the date when you install a cartridge so you can plan purchases around your own appliance. If you choose a multipack, keep the spare cartridges in their packaging and follow the storage directions until you need them.
Confirm the label when the order arrives
Read the package label and compare it with your order, the appliance model notes, and the manual’s part reference. Check that the cartridge is intact and that its orientation markings agree with the instructions. Open the refrigerator filter cover using the documented method and position the cartridge as directed.
After installation, check that the cover closes in its intended position. Use the manual for any filter reminder reset, because the sequence depends on the refrigerator controls. If the cover or reminder behaves differently from the instructions, note the appliance model, selected cartridge, and what you observed before asking for help.
Keep the information for the next order
Put the full appliance model, verified air filter code, cartridge photograph, and installation date in one place. Include the manufacturer’s reference or manual page and the exact variant you bought. A quick record is useful when the old packaging is gone or several product listings use nearly identical photographs.
Review the current SEISSO listing if your appliance documentation calls for the Pure Air Ultra II family. Compare your confirmed reference with the listed codes and select the pack that suits your needs. When a refrigerator is replaced or moved to another location, update the record so the next purchase follows the new model’s instructions.
