How to Tell if Your Refrigerator Has an Air Filter (GE, Sub-Zero, Frigidaire)

Open your fridge door and catch a whiff of old onions or fish. Those smells linger and mix with everything else. An air filter traps odors and keeps food fresh longer. Many people search "does my fridge have an air filter" because bad smells frustrate them.

Most new refrigerators include one, but older or basic models often skip it. This guide shows simple ways to check. You learn model lookup tips and common spots for GE, Sub-Zero, and Frigidaire units.

Step 1 – Locate Your Refrigerator Model Number

Find the model number first. Look on a sticker inside the fridge door edge or on a side wall. Some appear on the back or bottom.

Grab that number. Visit the maker's website or open the manual. Search your model. Sites list parts and features. If an air filter shows up, your fridge has one. This way works best and takes little time.

Step 2 – Look for Control Panel Indicator Lights

Check the control panel next. Many models flash a "Change Air Filter" or "Pure Air" light when time comes to swap it.

See a red light or message? Your unit likely has a filter. No sign does not always mean none exists. Some lack indicators. Still, lights give a quick clue on newer fridges.

Step 3 – Check for Physical Filter Locations

Inspect inside the fresh food section. Filters hide as small rectangular charcoal pads behind a cover.

Look at the top, back wall, or near vents. Remove shelves if needed. Spot a plastic housing or grille? Pull or slide it open. Find a black or gray cartridge? You have a filter.

Step 4 – Brand-Specific Locations and Tips

Brands place filters in set spots. Details help you search faster.

GE Refrigerators

GE units often put the odor filter in the upper left or top rear of the fresh food area. Some Café models hide it behind a cover on the left rear wall.

Enter your model on the GE parts site. Use the first eight digits. See an ODORFILTER part? Buy it and confirm the feature.

Sub-Zero Refrigerators

Sub-Zero builds air purification into select lines only. Classic, Designer, and PRO models include it. Others do not, and you cannot add one later.

Find the access door on the back wall between top shelves. It sits right or left based on the series. Open it to see the cartridge.

Frigidaire Refrigerators

Frigidaire spots the PureAir filter at the top center or near vents in the fresh food section. Slide or unscrew the cover to reach it.Type your full model on the Frigidaire site. No filter listed? Call support. They check fast. Learn more in The Ultimate Guide to Refrigerator Air Filters for extra tips on types and benefits.

Step 5 – How to Identify the Filter

Spot the filter easily once you find the housing. It looks small and rectangular. Black or gray charcoal fills it. The plastic cover snaps or slides off. See that setup? Your fridge fights odors with a built-in system.

Step 6 – Alternatives if Your Fridge Doesn’t Have a Filter
